You will see difference!

if you're looking to turn around your thinning hair, then definitely try this. Only after first use, you will know if this suits you. It will thicken, darken, and soften your hair. Will change the look of your hair.

I have been using this product for some time now and i have definitely noticed some hair growth. I am one yr postpartum and experienced a lot of hair shedding. This product does not leave your hair oily. I use it after I shower and it smells amazing! My hair feels and looks very soft after !
