Amazing product

[This review was collected as part of a promotion.] Finished a whole bottle of this product and just ordered my second. Takes a few weeks of consistent use to notice a difference, but it has definitely made my hair way thicker and stronger. Will be buying this product again!

Hair feels great and healthier

I like using this in combo with the genesis serum. I feel like the two products work so lovely together, strengthening existing hair while also allowing for new growth. Love the way it feels and will continue to use
