[This review was collected as part of a promotion.] What a game changer! I had sooo many fly aways! My hair was always so staticky and dull. After using this product in just one use I could see a difference. I continued to use it as needed. I definitely recommend and it smells amazing too!

[This review was collected as part of a promotion.] This product is safe in color hair and I love it! As you can tell in the photos I have one side where I put the product in and one side where I didn’t. On the side where I used the product my red is more vibrant and you can see the frizz is gone. I tend to have very dry skin because I use a lot of dry shampoo how’ve once I use this product it adds back in so much moisturizer. I am not sure how much this cost but it is definitely something I would buy for my hair to knee it healthy in the future. The appearance of the bottle is mid but the product does so much more than that.

[This review was collected as part of a promotion.] This product is AMAZING! My hair is shiny and stopped shedding! The smell is so nice and feels like a fresh was everytime. I have all my friends buying this product and they love it!

[This review was collected as part of a promotion.] First, I was impressed with the bottle and pump. It is easy to control the amount of product you get. The serum is thin and not greasy at all. I noticed the scent right away. It’s light and fresh. Not too heavy or overpowering. It would not compete with other products you might use. I first tried it at night on dry hair. I used a nickel size amount and worked it from the mid-section of my hair through the ends, and went to sleep. In the morning, my hair was soft and shiny. I didn’t shampoo that morning, and styled my hair as usual with a curling iron. My hair still styled great, with no residue, just soft shiny locks. The next day, I tried the serum again, this time on damp hair, and immediately blowed it dry, and styled with a curling iron. This is where I usually have trouble with frizz and fly aways from the heat styling. The serum definitely protected my ends throughout styling, and my hair still curled easily. The difference is I had no frizz, no fly aways, or broken ends sticking out. Just soft beautiful curls. I absolutely love this serum. It will be a staple for me from now on. It is a must have if you heat style, have damaged or color treated hair. Or if you just want soft, shiny beautiful hair. You need to try this serum!

[This review was collected as part of a promotion.] So have fine, straight hair with a lot of blonde highlights and my hair can get dry to the point that even a hair mask does nothing. I work the serum into wet hair and blow dry. It completely brings my hair back to life, leaves it super soft and smooth. The scent is light and I find it to be pleasant. It's a smallish bottle but you dont need a ton, just distribute it well! You can also use it on dry hair and it still works so well and doesn’t make your hair look oily! All in all, I love this product and feel like you would too if you were to give it a try!!

This right here loves it! I am mixed, and nothing ever has been the best for my hair but Redkens. When I seen they had a new product for curly hair, it sold me. The day and night serum on top is a must have in the bag. Before I even shampoo use the detoxifier shampoo and results are immediate! If anyone can reach out about advertising and promote products please reach out I have before and after pictures. And a video of me talking about products as I as a hobby style hair.

[This review was collected as part of a promotion.] I have bleached hair, so I am always looking for conditioning and repairing hair products to minimize damage and make my coarse, overprocessed hair more manageable. The Redken Serum has a light lotion consistency, so more watery than a hair mask which makes it appropriate for daily use. I apply it to the dry ends of my hair, and while other products such as hair oils leave my hair weirdly crunchy the next day, this serum sinks into my hair without leaving any noticeable residue. I have tried soo many hair products including olaplex and I really like this serum! Also, it’s great that it can be used night and day.
