Rated 5 out of 5 by from Satisfied First off, love the smell! Perfect use after the step 1 , shampoo.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 Lightweight but effective This conditioner is very lightweight, but does a great job making my hair feel soft, not weighed down at all. Love it.

Rated 2 out of 5 by from Not a favorite I don’t feel like it’s moisturizing like they claim it is. My hair felt gritty and got dirty a lot faster than normal. I wouldn’t recommend using this.

Rated 4 out of 5 by from Great for thin hair! I have recently started using the entire Redken Acidic Grown System. This conditioner is great, it is on the thinner side compared to some of their other products. It does not weigh down my hair but does still condition my hair. Easy to rinse out, does not leave hair oily or with a residue. The scent is neutral and great for both men and women who are looking to improve their scalp health and hair growth.

Rated 4 out of 5 by from Lightweight and fresh I received this product free of my honest review. As always a fan of Redkin products. This conditioner was not as thick as I expected, yet really conditioned well. It left my hair smooth but not weighed down.

Rated 5 out of 5 by from Leaves hair feeling super hydrated and no build u Very lightweight with great scent! Hair feels fantastic!

Rated 5 out of 5 by from Great conditioner Redken sent me this free sample through the BzzAgent sampling program. Just like the shampoo, this conditioner works very well at providing moisture & volume to the hair. A little product goes a long way. Its not heavy feeling, so it's great for thin, fine hair like it is ment for. It did not make my hair greasy or leave any weird residue. I would recommend this to be used with matching shampoo to get the fullest benefits of this conditioner. If your hair is limp & lifeless, give this duo a try.

Rated 5 out of 5 by from Good and Lightweight I loved the texture of this conditioner, I find it to be a suitable part of the full system. Works great with the shampoo so I would recommend bundling it if you haven't already to notice the benefit. I'd recommend for medium to finer textures of hair as it has a very light conditioning benefit but it is definitely helpful if you are looking to style and keep volume in the hair.

Rated 3 out of 5 by from Wanted more 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 Conditioner just sorta left me hanging and wanting more. I like that it appears to be dye free and works into the 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, and it left my hair soft. Using this with the whole system helps my hair feel more fuller

Rated 5 out of 5 by from Soft, Volumizing and not Heavy 5 stars! I really love this Conditioner. It makes my client's hair feel soft, smooth, and healthy without weighing it down. It pairs really well with the shampoo and helps give hair tons of volume while still feeling lightweight. It smells so clean and nice too. It does not irritate scalps and leaves the hair feeling clean, nourished and easy to manage. Definitely a great conditioner and I highly recommend!

Rated 3 out of 5 by from Works great Smells good, works nicely on finer hair! Suds up well & seems to leave a nice shine!

Rated 5 out of 5 by from The perfect accessory if you want more density The conditioner to this 4 part system pairs well with the shampoo. It's thick and smells great. It coats the hair and helps with density.

Rated 3 out of 5 by from Great Conditioner I enjoy the texture of the conditioner, I have noticed my hair feeling a bit more dry after using this conditioner. I have tried the shampoo with other conditioners in the Redken line and like the combo better than together. I would like to have more time to see if this line does help with growth, but overall I would recommend for someone struggling with volume and for someone with more fine hair

Rated 5 out of 5 by from Love this line My curly hair felt so soft and hydrated after using this, and the scent is light but fresh, not overpowering at all and I’m really sensitive to fragrance.

Rated 5 out of 5 by from Hydrating without weighing my hair down Redken sent me this free sample through the Bzzagent sampling program in exchange for my honest review. After shampooing my hair I dispersed this conditioner from my roots to ends and left it on for 3 minutes. This conditioner has a nice citrusy herbal scent to it that fills the shower. I found this product to be deeply hydrating without weighing my hair down. After washing this conditioner out of my hair it felt soft and was easier to comb through.

Rated 5 out of 5 by from Soft voluminous hair I absolutely love this product. Light weight conditioner, you get volume without your hair feeling like straw and weighed down. Hair felt soft and smooth. Light fresh scent.
Date published: 2026-03-04
Rated 5 out of 5 by from Leaves processed hair so soft! I really like this Redken acidic line as I have fine, over processed hair, short hair and it’s been making a difference overall. I’m using the whole line and I do think that matters! The conditioner is creamy, has a nice texture and leaves my hair feeling quite soft. I like the smell, it’s refreshing and oceany vibes. Def gender neutral.

Rated 5 out of 5 by from Get it Love using this conditioner with the shampoo. Not super heavy and does not leave hair greasy or weighed down.
Date published: 2026-03-03
Rated 5 out of 5 by from Love! Love using this conditioner! In combination with the shampoo, this is the perfect duo! Perfect for people with fine hair!

Rated 5 out of 5 by from Loving it so far I received this product as a free sample in exchange for this review and I love it. Paired with the shampoo it makes my hair so soft and silky. I’m hoping with longer use it will help my fine hair grow longer. Overall I like this line so far.
Date published: 2026-03-02
Rated 5 out of 5 by from My new favorite Little skeptical of the shampoo at first but after giving it a try, it’s an instant yes for me. My hair feels super clean and looks fuller. I’ve noticed a lot less shedding as well!
Date published: 2026-03-02
Rated 4 out of 5 by from Nice overall I thought this was a great product. wasn't a huge fan of the smell and I did not think that it had really good de-fluffing properties. hair especially curly textured hair was still very fluffy afterwards

Rated 3 out of 5 by from Best for short hair Not very moisturizing if your hair is dry. Nice scent
