Smoother and fuller looking
[This review was collected as part of a promotion.] I’ve really enjoyed using this shampoo. The texture and scent of the product are both really lovely and I’ve really seen a difference in the appearance of my hair over a short time too. I’ve used the shampoo in my routine alongside the matching conditioner, hair serum and densifying spray. Using the combination of products I feel as though my hair is stronger, smoother, shinier and appears fuller too, which I love! I have struggled with split ends for a while now and these products have really helped to stop my hair breaking so easily. I have really enjoyed testing out these products!

Cleans well and leaves hair soft
[This review was collected as part of a promotion.] I have been using this shampoo for around two weeks and I am very pleased with the results. It cleanses my hair thoroughly without drying it out and leaves it feeling fresh and soft. My hair looks healthier and has a little more volume at the roots. The scent is lovely, and the product feels like a professional salon-quality treatment. I will definitely continue using this shampoo and would happily recommend it to others.

Great for thin hair
[This review was collected as part of a promotion.] Redken acidic grow full shampoo is a powerful product to help add volume and nourishment to flat and thin hair. My hair always ware lacking of volume and I can see a huge improvement since starting this whole range. Even after first wash my hair ware lifted and easier to style. I also love the scent of this shampoo. It is fresh and citrusy, very luxurious.

Really impressed!
[This review was collected as part of a promotion.] I have found this shampoo to work really well. I often have to shampoo twice to feel like my hair is properly cleaned but not with this product. My hair looks super shiny, clean and also seems to last longer before getting greasy. It smells great and the bottle will last a long time. I would really recommend this range as a whole and have seen noticeable results after using the 4-step routine over the past week and a half.

Lathers up well but unsure of any growth
[This review was collected as part of a promotion.] I was gifted this product in exchange for an honest review from Home Tester Club.
The bottle works well, however it is difficult to squeeze out when there is only a small amount remaining.
The shampoo has a pleasant smell, which is not too strong.
The shampoo ladders up very well and you only need a small amount to wash your whole hair which makes it good value.
I haven’t seen any benefits to my hair growth or thickness. This may be linked to the short testing period. Therefore I would have to give it longer.
I do have frizzy curly hair and unfortunately do feel that this shampoo dries out my hair.
I would recommend all to try this as it may work for them.

Already seeing changes!!
[This review was collected as part of a promotion.] This has been an absolute godsend after struggling with postpartum hair loss. Since using this shampoo my hair is growing back rapidly! Leaving it soft and feeling fuller.
Leaves scalp feeling clean and refreshed.
I would 100% recommend this, especially if you’re struggling with hair loss and want results.
