Clean and fresh

2 months ago
[This review was collected as part of a promotion.] This densifying spray works great with the rest of the system. It is the last application in the hair growth system and you spray it onto your scalp and then comb it through. The main thing I notice, even after following directions, is the I will have residue in the spots where I spray directly, even after I comb through and style. It’s not really bothersome and I otherwise love the way it makes my hair feel. I have been seeing new hair growth coming in and I love the fresh scent of this product. Highly recommend!

Nice product!

4 months ago
[This review was collected as part of a promotion.] I was excited and nervous to try this new Redken Acidic Grow Full System Instant Densifying Spray . I have natural, long, thin hair with oily roots and dry ends. In 90% when I try new sprays serums or other leave-in products- my roots look greasy and feel heavy! I experienced bad hair loss recently - I need to help my hair. I use this densifying spray after Shampoo, conditioner, serum from the same Redken System. I just spray it on my damp hair after serum and use hairdryer as usual. Watch my video - this is the proof- how soft and light my oily roots feel after BOTH leave in products from this system. I’m impressed!!! Will continue to use this spray for my hair. Hope it’ll help with growing new beautiful hair.

Smells Great and Adds Texture and Volume

2 months ago
[This review was collected as part of a promotion.] I have used Redken products in the past and had a favorable experience, so I was very excited to try this. At first I wasn’t a fan of this product because it left my hair feeling very stiff and crunchy. I realized it needs to be combed through and fluffed several times once hair is dry, and that crunchy feeling goes away. It is a pain to have to do this, and takes a fair amount of time. I air dry my hair, and this product makes my hair take significantly longer to dry, which I also don’t love. It adds slight volume and texture, but nothing too noticeable. For me personally, the results are not a significant enough trade off. I get almost the same results from the shampoo alone, which doesn’t require fussing. I much prefer the serum from this line to this Densifying spray, and I don’t think both are necessary. It smells absolutely amazing and is the same scent as the rest of the products in this line. If I had to describe it, like ocean air- sea salt and citrus. It is fresh without being astringent, and definitely a unisex scent. The pump broke after the first time I used it. There is a small lock button on the side that broke off, so I can’t get it out of the “lock” position. I did not drop the bottle or anything, so it seems like it might be a quality issue. This product is fine, and gives positive results, but I can’t wholeheartedly recommend it. Go with the serum instead.

✨️ Soft, Flexible Body ✨️

4 months ago
[This review was collected as part of a promotion.] The Acidic Grow Full Instant Densifying Spray added the most body of the products in the product line. A sprayed it 6" from my scalp, massaged it into my scalp, and combed it through my hair (as directed). It gave a lifting effect to the roots, and dried into a soft texture. It claims to "coat the hair fiber for an instantly denser look." My experience aligned with this claim. My hair was noticably fuller. This change was more noticeable when combined with the entire Acidic Grow Full System. Each product within the Acidic Grow Full System had a subtle botanical aroma- similar to blue chamomile. It came across as natural, not perfumey. Over the course of a week, I noticed my hair become less frizzy and more shiny. There has, also, been less breakage and hairfall in my brush. Overall, I highly recommend this product!

Magic in a bottle

2 months ago
[This review was collected as part of a promotion.] I received this product for free and exchange for my honest opinion I have super thin hair so any help I can get in making it appear thicker is a huge plus! I really loved this densifying spray! It not only made the hair look thicker, especially on my crown where it’s the thinnest, but it made it feel healthy. It was a tiny bit sticky because I shower at night, but overall it did its job and it’s a product I’d love to keep up with to continue seeing results.

Length and volume

a month ago
[This review was collected as part of a promotion.] The acidic grow full product line has really helped grow my hair along with making more volume for me. I typically have very thin hair and it is very hard to give it any movement. While using instant densifying spray I was able to achieve a little bit more length and a little bit more volume. Simple to use after the shower and doesn't dry out my scalp like some products. Spray nozzle held up well, I ended up wiping it off after use but it only took me a second to make sure there was no buildup on the nozzle. A nice fine mist helps to make even distribution of the product in my hair. Definitely a good system.

Love it! Gives nice complete feel and look

4 months ago
[This review was collected as part of a promotion.] Disclaimer: I have received this Redken Acidic Grow Full System Instant Densifying Spray absolutely free in exchange for my honest review. I was pleasantly surprised how great this densifying spray is. It gives you a really nice lift. I usually use this as the last step of my Redken routine. After shampooing and condition i get the serum worked in and then go spray happe all over my hair. It makes them feel really nice and full as well as smell nice. Unfortunately it doesnt smell as delicious as the shampoo but it will do! Love it! Just makes sure to spray not to close to your head though otherwise your hair will just feel crusty. Put some distance between your hair and spray.

Beautiful hair

[This review was collected as part of a promotion.] This spray gives me instantly volume, it really delivers, I apply it to damp hair and can see the lift at the roots right away, it doesn’t leave my hair stiff or sticky, on the contrary maintains a natural finish with movement, it also like that it provides heat protection when I use styling tools and I love the fresh scent that it leaves in my hair, smells so clean.

Adds texture to the hair

3 months ago
[This review was collected as part of a promotion.] I received the Redken Acidic Grow Full System Instant Densifying Spray as a courtesy to test and review. This spray has the same Lemonchello scent as the rest of the system. The bottle has a nice spray function with a locking and unlocking tab which is great for travel. This Densifying spray feels and acts to me like a sea salt spray. While wet, this product is slightly tacky and once dried, feels like the hair has a gritty almost texture to it. This threw me off a bit as the Redken products are usually soft and clean feeling to me. I am excited to see the after affects after use over time.

Instantly thickens hair!

4 months ago
[This review was collected as part of a promotion.] This is one of those products I didn’t realize I needed until I started using it consistently. The Instant Densifying Spray gives my hair that immediate fuller look without feeling sticky or stiff, which is huge for my fine/thinning hair days. I spray it at the roots and through the lengths before styling, and it instantly makes my hair look thicker and more alive, not weighed down. It also layers really well with heat styling and doesn’t leave that crunchy residue some volume sprays do. Keeps my scalp feeling clean and very easy to wash out at the end of the day. I don’t feel any residue left behind. The product thickens my hair to last all day and I work in a hospital so some days are more trying than others.

REDKEN instant densifying spray

3 months ago
[This review was collected as part of a promotion.] Girls, if you are following to the newest trends, and if you love hair volume like I do, try this product, this one is addictive. I am gonna tell you how I use it: I spray it at the roots before blow drying, I swear, difference and effect is visible after even first use. My hair looks fuller, without feeling stiff or crunchy. What I noticed is that it does not make fake volume. It enhances what you actually have. For my thin, postpartum hair that struggles with styling, this spray makes everything easier. My blowouts last much longer, my roots don’t collapse in two hours, and I don’t need heavy teasing anymore. Plus it has thermo protection formula. After styling I do not even use some setting products because there is no need for that. Thermo protection is the most important plus in my opinion. The product has such a clean, natural and light scent. IDK what formula are they using but it is fact, the ingredients are chosen very carefully, so the result is just amazing. I was frustrated, my thin hair got even thinner after pregnancy and breastfeeding, styling became disappointing instead of enjoyable, I missed feeling confident about my hair… and this REDKEN system gave me everything I needed. It strengthened, reduced shedding, made styling easier,gave my hair body without weight. This is exactly what thin hair needs. Highly recommend but for the best result, I recommend to use a full system and don’t skip steps. shampoo, conditioner, serum, spray.

Almost perfect

4 months ago
[This review was collected as part of a promotion.] I’ve been using full Redken Acidic Grow Full system. Overall I’m genuinely impressed so far. The densifying spray smooths hair while adding structure and light fullness without any stiffness . I’ve noticed less breakage while styling and my hair looks more polished overall. The scent isn’t anything memorable but it’s clean and pleasant. A tea tree oil and rosemary base with a subtle hint of citrus. It smells fresh and herbal but fades after awhile on the hair. The systems works best when used together. Each product complements the others, creating healthier looking, smoother, fuller feeling hair. While the scent isn’t a standout feature, the performance is. The system creates a solid foundation for stronger fuller looking hair while supporting scalp health.

Boost for thin flat hair

3 months ago
[This review was collected as part of a promotion.] The final step I use in Redken acidic grow full system is the density spray while my hair is still damp. The spray distributes evenly and doesn't leave a sticky or heavy feeling. It adds a bit of grip and body, which helps my natural thin, flat hair look fuller when it dries. I like how it layers well with the serum without weighing my hair down. The density spray has bright citrus scent, keeping the whole routine cohesive. My hair feels light, fresh and more lifted after styling.

My favorite acidic grow product

2 months ago
[This review was collected as part of a promotion.] Redken's Acidic Grow densifying spray is my favorite product from this line. The locking mechanism on the bottle is useful for making sure it doesn't spray when you're traveling and I don't think I've ever seen another hair product with a little toggle to lock the lever, so I thought that was pretty cool. I feel like this product, which happens to be step 4, is the only one that makes a noticeable difference in my hair. I could do without the shampoo, conditioner, and serum. In fact, I've used this densifying spray after using regular shampoo instead of the rest of the Acidic Grow line and still had good results.

Kinda slimy

2 months ago
[This review was collected as part of a promotion.] I received this product for free in exchange for my honest review and opinion. Nice size bottle with a closing mechanism so it won’t spray out into your shower bag at college or when going on vacation. It dries super fast but the consistency was kind of slimy. It has a pleasant clean scent. The instructions weren’t very clear but I assumed that you spray it on your roots and rub in the help strengthen your hair and promote growth. I didn’t see any visible results after two weeks of use every single day. It left my hair a little crunchy.. my hair density didn’t seem to change. Great value but wouldn’t purchase.

My hair felt soft and manageable. Drying time was average to normal drying time of my hair since I applied it to my wet hair. I feel this is very great quality and and sprayed evenly where I wanted it to. The direct nozzle makes it easy to apply exactly where you want it. I am very satisfied with this product.

Spray ph balance and growth

3 months ago
[This review was collected as part of a promotion.] This spray goes on easy with good coverage and easy to hold to apply. It light weight doesn’t weigh the hair down and the fragrance is light and pleasant. It didn’t make the hair feel sticky or greasy. My hair when dry felt like dry straw and not sure if due to winter in SoCal which is dry or low/no humidity or if due to being first time using a ph balance product but it also made my scalp itchy due to dryness without dandruff

You’re So Dense!

4 months ago
[This review was collected as part of a promotion.] First off, I absolutely HATE the packaging of this line…especially the Densifying Spray. I went to apply to my hair and *pop* - the entire top with the trigger went flying!!! I was able to snap it back on, but it took some work popping it back together. Then…it wouldn’t even spray. After about 40 tries, it finally worked! So exhausting!!! All that said, once I got the protect applied, my hair DID feel a little denser…like there was more ‘meat’ to each strand. Not a huge amount, mind you, but to the point I could feel it in my fingers. I’m not positive it can perform any miracles on my thinning hair, but it’s a nice product. There’s no real scent I could detect and the product is clearish so there was real wrestling to get the product to blended in. Hair feels a little more dried out than usual, but I think that’s to help build the illusion there is more hair.

Now this isn't a volumizer, you're not going to get huge bouncy hair but you will get a nice subtle boost. Feels and smells refreshing! Very easy to use. Using this product along with the rest of the acidic growth line for the past month, I have a good amount of new hair growth/baby hairs! Can't wait to see the long term use results!!

Helping my hair get healthy while giving it shine

4 months ago
[This review was collected as part of a promotion.] Doesn’t leave any oily or residue or stiffness on your hair. Easy to apply while spraying . Easy to style afterwards and my hair looks thicker from applying the spray. Although I do use the entire system from shampoo conditioner to the sprays to not sure how the results would be alone. I’m sure it would give volume but this actually makes my hair healthier. As for hair growth I would need more time to tell.

Works well, pair this with the hair growth system

3 months ago
[This review was collected as part of a promotion.] First I want to thank Influenster and Redken for this complimentary hair system for my honest review. This bottle comes in a plastic bottle with a squeeze handle. This product does hold your hair and makes it crunchy and stiff. For better use I spray it closer to my scalp and work it into the scalp and top of the head only while my hair is wet. It does not have a scent, at least not to me. This works well as far as I can tell. Pair it with the rest of the hair system. It does not dry out my scalp or cause any irritation. I give this 5 out 5 stars. I recommend this product.

Adds volume, but dirty hair feel

2 months ago
[This review was collected as part of a promotion.] I was very curious about this product, but was interested to know that my hair felt very sticky when using it following the shampoo and conditioner in the system it almost felt like I put in a texturizing spray at my roots. It made it very hard for me to run my fingers through my hair and felt dirty at the end of the day as if I had to wash it even though I just washed it with the full system. I’m not sure if I would label it as an identifying spray, but it definitely feels more like a root lifting spray. I thought by the packaging it was meant to be more of a hair growth product but in this case it’s just to make the hair look fuller which it does, but the hair feel is a little uncomfortable.

Hi there! Thank you for reaching out about our Acidic Grow Full System Instant Densifying Spray. We appreciate your observation regarding the product's function. You are correct that this is a styling treatment designed for instant volume and fiber expansion, rather than a long-term hair growth product. It acts similarly to a root lifter by coating each strand to create the appearance of thicker, fuller hair immediately. The "sticky" or "texturized" feel you described can sometimes occur if the product is concentrated in one area or if too much is applied to dry hair. For the most comfortable results, we recommend: Applying to damp hair only. Focusing on the roots and combing through to ensure even distribution. Using a blow-dryer to help "set" the densifying agents, which typically removes that tacky sensation and leaves the hair feeling fuller but manageable. Your feedback regarding the packaging and "hair feel" is incredibly valuable to our development team as we strive to balance high-performance results with a professional finish.

Just okay

2 months ago
[This review was collected as part of a promotion.] This Redken Grow Full Instant Densifying Spray I found to be just okay. For one, the sprayer broke almost instantly which made it pretty much unusable. When it did still work it definitely added texture my my hair but left it feeling kind of dry and crunchy. I could see using this for maybe before an updo kind of hairstyle but wasn’t for me for everyday use.

Hi there! Thank you for reaching out about our Acidic Grow Full System Instant Densifying Spray. We are truly sorry to hear about the issue with your packaging and your experience with the Redken Acidic Grow Full System Instant Densifying Spray. A broken sprayer is certainly not the professional experience we strive to provide, and we appreciate you bringing this to our attention. Regarding the "dry and crunchy" texture, this sensation can occur because the formula contains high-performance densifying agents designed to wrap around each hair fiber to create immediate volume and grip. While this texture is excellent for updos and styles requiring extra "hold," for a softer everyday finish, we recommend: Applying the spray to damp hair only. Focusing application at the roots rather than the ends. Blow-drying the hair immediately after application to help "melt" and set the densifying ingredients for a fuller, smoother feel. Your feedback is invaluable to our quality and development teams as we work to improve both our packaging and user experience.

Even coverage, dries down well

4 months ago
[This review was collected as part of a promotion.] Redken AcidicGrow has a scent similar to tea tree oil. The Densifying Spray was a little sticky at first, but dries down nicely. My hair definitely appears fuller after the first use. While a bit awkward, the trigger spray does have a pretty fine mist with even coverage! If you struggle with fine or thin hair, this is a great product.

[This review was collected as part of a promotion.] This products is great for styling days. I spray it near my roots and it gives my hair a fuller look without feeling sticky or stiff. It does not make my har crunchy which I appreciate. It just adds a bit of body and makes my hair look thicker, especially around the crown. It is subtle, but you can definitely see the difference.

It works well!

2 months ago
[This review was collected as part of a promotion.] This product used with the rest of the suite of products works well and does create body and density. If you let it air dry it will make your hair crunchy but it does comb out and still provide volume/density. I wish it wasn’t as soapy smelling in fragrance. Otherwise it was impressive in its results.

Didn’t work for me

2 months ago
[This review was collected as part of a promotion.] Waited awhile to review because I really wanted to try the product and see if it worked. I’ve used it for three washes now and I haven’t seen a difference in thickness or fullness. I really wanted to because my hair needs it after being postpartum for a year and a couple months now.

We hear you, and we are sending so much love to you on your postpartum journey! We know how important it is to feel like yourself again, and we’re truly sorry you haven't seen that boost in fullness after three washes. Hair density and thickness can often take a bit more time to show visible changes, especially as your body continues to transition. We truly appreciate your patience and for giving Redken a place in your routine—we're rooting for you and your hair! 💖✨

This Densifying Spray Will Lift Your Roots

4 months ago
[This review was collected as part of a promotion.] The Redken densifying spray used in conjunction with the shampoo and conditioner, gave my roots a sure lift. I tested out just the shampoo and conditioner alone on one day, and then the shampoo and conditioner with the densifying spray added in on another day. I definitely got more lift with the addition of the densifying spray. I did, however, find that I had a little bit of a coated field to my hair where the spray had been applied. My hair did not feel as silk like and flowy like the day when I had only used the shampoo and conditioner. I personally do not like when I can feel product in my hair and when it changes the texture. This was partly user error as the directions do specify to use primarily at the roots. Going forward I will ensure to use this only at the roots and not comb throughout the rest of my hair to avoid the coded texture throughout my lower strands. I think this is the key to using this product as that is where the lift is needed. The product does what it says it will do; it adds volume!

Did make my hair look fuller

4 months ago
[This review was collected as part of a promotion.] I used all four products and blow dried for the before and after. My hair did look fuller, but nothing dramatic. I have very fine, straight hair, so any body is a win. This product did make my hair a bit “crunchy” at the roots, but I may have applied too much.

[This review was collected as part of a promotion.] I tried Redken Acidic grow system densifying spray ,And i am very impressed with it. The spray is lightweight and easy to apply . it gives my hair extra volume, And makes more fuller and thicker without feeling greasy and heavy. I like that it helps lift the hair from the roots and makes style easier ,especially when i blow dry my hair. my hair feels soft, natural and more manageable. it also provides heat protection , which is very helpful for my hair. package is modern and very easy to use. scent is also nice. overall, like this collection, my hair is better now !

Damaged my hair

2 years ago
It fried my hair gave me a color chemical burn. My hair has never gotten damaged from using shades eq this was my 1st time using shades eq plus bonder . My hair strand elasticity strength is weak and breaks off and coils back crunchy , it feels like gum I used it as directed and I don’t have any medications and it felt horrible while I rinsed it with just water before I used my vegan shampoo It’s been a horrible experience, I’ve been using non permanent hair color for a couple years now to regrow natural healthy hair. And now my entire hair strand is damaged. I contacted redken directly and the rep was rude and kept talking about herself and how she’s a chemist and she burns her hair off and blah blah blah. Very rude I’m literally in shock .

No, I do not recommend this product.

If you use it correctly, it is magical

a year ago
My stylist uses this on my hair when I get my balayage lightening. Rather than paying 80.00 for a toner application only between full services, I decided to try it at home. Mixed it exactly as was described using 2 bonder colors (9V and 10GRo), 000 crystal clear, and the processing solution. Applied to clean, dry hair and left it on for 20 minutes. May hair looks like I just left the salon. It is shiny, soft and the color is exactly what I was looking for. I realize doing a home hair color job is not always recommended and can be done incorrectly, but I followed all the directions and it came out perfect.

Yes, I recommend this product.

DREADFUL PRODUCT!!

2 years ago
I used the product a week ago. It made my hair extremely, dry, fizzy and stiff -- more like straw than hair. I to correct the situation by using deep conditioner, mask, your 25 Benefits One United in an attempt to reverse the damage/condition -- no improvement. I couldn't be more upset, worried, unhappy and at loss as to how to restore my hair to its previous state..

No, I do not recommend this product.

Crap product

I used the shades eq gloss and the gel product with it and my hair is HORRIBLE now. The color is cute but my gorgeous soft long hair is freaking straw now. I can’t even wear it down it’s so staticky. Redken ruined my hair
