Works as described!

5 months ago
[This review was collected as part of a promotion.] This conditioner is creamy and dense like most but it didn’t seem to weigh the hair down although I still use a minimal amount of any conditioner to not flatten my hair. It does have a soapy smell to the line which isn’t my favorite but could be worse. It worked well with the other products. I’m not sure the conditioner and shampoo alone would make the max difference in volume density. The size is reasonable and would last pretty long unless you have super long hair. I didn’t know Azelaic acid could be used on the hair I’ve used on skin for dark spots.

Fresh and clean

5 months ago
[This review was collected as part of a promotion.] This conditioner is the perfect complement to the shampoo in this set. The conditioner add moisture and keeps my hair feeling smooth and strong. It washes out like any other conditioner. The scent is fresh and not overpowering. After several weeks of use I have noticed new hair growth coming in and my hair looks great. Highly recommend!

Conditioner ph balance and growth

6 months ago
[This review was collected as part of a promotion.] The conditioner felt good to apply to the hair. With a semi thick consistency that coats the hair nicely and requires to leave in for 3 minutes. It has a pleasant fragrance and initially it felt amazing. The day after I washed my hair my scalp was extremely itchy and dry with no flakes. It could be that I’m based in Southern California where it’s dry or low humidity and / or this being the first time I’ve used a ph balance product. I did use it as a second time three days later and again my scalp was very itchy due to dryness scalp and lucky with no dandruff. This probably better for use either once a month or in a more humidity environment.

In Great Condition

7 months ago
[This review was collected as part of a promotion.] I HATE the packaging of this line…the conditioner packaging is small, only 10oz, and has a micro thin flip top which was almost impossible to open in shower. Wish it had more of a traditional push button or pump to dispense product. Conditioner was good, but not mind blowing. My hair texture didn’t feel any different after using this - just like any other conditioner. It has a super light, mildly chemically fragrance. It was easy to apply to strands with its “thicker than lotion but thinner than cream” texture. I would think it might do something with consistent use; however, it’s a luxury prograde for me, so I’d only be using for special ocassions.

✨️ Thick, Creamy, and Dreamy ✨️

7 months ago
[This review was collected as part of a promotion.] The Acidic Grow Full Conditioner was thick and buttery. It enveloped my hair in luxurious moisture. I left it in for 3 minutes before rinsing (as directed), then it rinsed out cleanly. Once my hair dried, it felt silky and bouncy. The conditioner claims to "coat the hair fiber for an instantly denser look." My experience aligned with this claim. It was subtle, but 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!

Favorite conditioner so far!

5 months ago
[This review was collected as part of a promotion.] I am RARELY a fan of conditioner because they weigh down my hair, but I really grew to love this one! I especially think you have to use both the conditioner and shampoo to get the full effect. This conditioner, when used before the shampoo, made my hair fuller, softer, and full of life. It was easier to manage overall. I let the product sit for three minutes prior to rinsing and used all over. Would love to continue using this conditioner!

Hydrating conditioner

6 months ago
[This review was collected as part of a promotion.] My hair is thin and tends to get oily quickly, so I'm always careful with conditioner. This one has a white, creamy texture that feels rich but not heavy. It spreads easily through the mid lengths to ends. After rinsing, my hair feels smoother, softer and easier to detangle while still feeling lightweight. I also enjoy the fresh citrus that matches the shampoo. Used together, my hair feels clean, balanced and not weighed down.

Worth trying!

7 months ago
[This review was collected as part of a promotion.] I love when the brands I love formulate products that is consumer conscious. Redken acidic grow full system conditioner is not only sulphate and silicone free but the bottle is made of 100% recycled plastic as well. It’s ph balanced hence the moisturised and healthy hair. So far I am absolutely loving it and definitely going to repurchase!

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.
