Amazing for length!

I was focused on growing my hair after a bad haircut and this did the trick! I saw great length within months and the bottle lasted around 3/4 months using it 2x a week after washing my hair! I prefer this over the Gensis growth serum - can’t recommend enough!

I love this product

[This review was collected as part of a promotion.] I have been using this product after every wash and my hair has gotten visibly thicker and unlike a lot of products, this one does not make my scalp itch.
