Great addition to haircare routine
[This review was collected as part of a promotion.] Easy to use product with a pleasant smell. Great product range for thin hair. I used this with the shampoo and hair felt thicker without being weighed down by the product. A little expensive but other than that great

A little goes a long way
[This review was collected as part of a promotion.] After my first use of this product I found my hair to feel a little greasy and oily to touch and look at. I’m hindsight I think I overused the product and didn’t comb it in enough. After my first use I’ve used it 5/6 more times since and have made sure to use less and comb it in properly. It’s been much better doing this and I’ve found that only a few sprays does the trick just fine for me. I’ve found that using this alongside the shampoo, conditioner and hair serum, my hair appears healthier and fuller and it’s really helped to boost my confidence. The spray pump is really effective so make sure to hold it far enough away to use it properly.

Not impressed
[This review was collected as part of a promotion.] I have been using this along side with the shampoo, conditioner and the spray.
Unfortunately this product leaves my hair stuck together and quite dry therefore I have been leaving this one out of my hair routine. However cannot rate the other 3 products enough!

Gives light volume to hair
[This review was collected as part of a promotion.] I have been using this spray for around two weeks. It is easy to use and does not leave my hair sticky or stiff. I have not noticed a dramatic increase in volume or hair density yet, but it does not weigh my hair down and helps keep it looking neat and manageable. Perhaps the results will become more noticeable with continued use. I plan to keep using it and would recommend it to anyone who wants to try a lightweight volumising product.

Volume in a bottle
[This review was collected as part of a promotion.] Redken acidic grow full spray is a basically volume in a bottle. Combined with the shampoo and conditioner from the same range it provide decent volume even for thin and flat hair.

Really impressed!
[This review was collected as part of a promotion.] I've seen impressive results using this spray along with the other 3 products in the range over the past week and a half. My hair looks visibly fuller than it has in years and super shiny. The range does what it says and I would definitely recommend.
