Rated 5 out of 5 by from Satisfied First off, love the smell! It does not smell like a chemical like some others do. Been using it on my clients and is loving the results. Their hair comes out much fuller and strong.

Rated 5 out of 5 by from Clean and fuller hair! This is a very nice shampoo. It lathers very well and makes my hair feel clean. My hair is has been thinning due to perimenopause, but this helps my hair to appear fuller definitely going to be a staple product.

Rated 2 out of 5 by from Not my favorite. The smell is good and overall it works ok. I didn’t feel like my hair felt super clean after and I feel like it got dirty really quick after using.

Rated 5 out of 5 by from Adding to my haircare line up I recently started using the entire Redken Acidic Grow System. This shampoo is great! I have curly hair and this shampoo cleanses but it does not dry my hair. Creates great sud and is a neutral scent.

Rated 5 out of 5 by from Lightweight but strong clean I received this product free of my honest review. As always a fan of Redkin products. This shampoo surprised me by lathering up right away. Very light weight yet had a great cleanse.

Rated 4 out of 5 by from Good Cleanse & Full Effect I would say this shampoo does what it needs to do as part of a system that helps in helping the hair feel fuller. I noticed a little bit of extra shed from my regular use so I did knock off a star for this, but I will note that it did a good job of leaving my hair feeling clean without needing a lot of it to do the job. If I wanted to build volume into the hair for styling, I would recommend this shampoo.

Rated 3 out of 5 by from Wanted to love...meh I really wanted to love this new Redken line since I'm a huge fan of the other Acidic lines. However, the Acidic Grow Full System Densifying Shampoo just sorta left me hanging and wanting more. I love that its clear and it truly has a great lather and cleanses the scalp and hair well. The smell is fairly strong like a chemical scent that I don't care for. It works ok for fine hair but doesn't not feel super hydrating. The claim is fuller hair, but I can't say I really noticed.

Rated 5 out of 5 by from Great product The smell is a very clean smell, it leathers up really nice. Using this with the whole system helps my hair feel more fuller.

Rated 5 out of 5 by from Great shampoo This made my hair feel so much fuller after one use! The smell is very fresh and a little goes a long way, very concentrated. Gives my hair a good clean feel, but feels so much denser. Highly recommend this for all my thin hair girlies.

Rated 5 out of 5 by from Great volume shampoo Redken sent me this free sample through the BzzAgent sampling program. This is a great shampoo that finally does what it says it will do, Add Volume! I love that it really does make my hair feel alot fuller and I also feel like it cleans my hair well at the same time. Some shampoos I've encountered in the past have a hard time doing both those things. This shampoo smells decent. Nothing special on that part, but its a nice smell without being overpowering. It works really well with the matching conditioner. It also works even better if you use the whole line of products with it. However, it definitely works on its own if you don't want the entire collection of products. I definitely recommended this to anyone with thin, fine or just lifeless hair. It adds just enough volume.

Rated 5 out of 5 by from Loved It, Clean Volume Without Stripping 5 stars! My clients all love this shampoo. It cleanses really well and gives their hair great volume without feeling stripping or harsh. The hair feels soft, fresh, lightweight after using it. It also smells amazing and best of all doesn't irritate sensitive scalps. Great product! It is gentler than other densifying shampoos. Definitely recommend!

Rated 4 out of 5 by from Good for fine hair Smells good, works nicely on finer hair! Suds up well & seems to leave a nice shine!

Rated 5 out of 5 by from The shampoo to keep your hair full The shampoo in the 4 part system is unbelievable. It smells like heaven. It makes the hair much fuller. It lathers up with foamy bubbles.

Rated 4 out of 5 by from Solid Shampoo I enjoy the texture and scent of this shampoo, I have noticed my hair feeling nicer and less breakage. I would like to have more time to see if this line does help with growth, but overall I would recommend!
Date published: 2026-03-06
Rated 5 out of 5 by from Love it! I absolutely love that this isn’t overpoweringly fragrant like a lot of shampoos can be. I was a little nervous to try it because sometimes the acidic bonding line can mess with my curls, but this actually seem to make my curls really happy.
Date published: 2026-03-06
Rated 5 out of 5 by from Gentle on my fine hair Redken sent me this free sample through the Bzzagent sampling program in exchange for my honest review. This Shampoo has a light lather to it and is perfect for prepping my hair for the acidic bonding grow full system. It cleanses my hair throughly without stripping it. I found the formula to be very gentle on my fine hair as well. This shampoo left a pleasant citrusy herbal scent on my strands that lingered in my hair throughout the day.

Rated 4 out of 5 by from Good cleansing with pleasant smell This product does a nice job of cleansing the hair and scalp. The smell is pleasant and not overwhelming.

Rated 5 out of 5 by from Clean fresh volume I absolutely love this product. Hair and scalp feels clean, you get volume without your hair feeling like straw. Light fresh scent.
Date published: 2026-03-04
Rated 5 out of 5 by from Great line! I have very fine over processed hair and this shampoo leaves my hair feeling very clean without feeling “stripped.” It lathers very well and you don’t need much product. I like the smell; it has refreshing ocean vibes, gender neutral smell. I def recommend using the whole line together as that’s where I’ve found the best results overall.
