    Healthy Scalp, Healthy Hair!
    Not only does this serum smell amazing, it has changed the game! As a breast cancer survivor who has lost and regrown an entire head of hair, this has returned my scalp health and inturn regrowth of lost or broken strands. I use this as part of an Ouai routine and I couldn't be happier with the results ✨️ Pairs great with Ouai detox shampoo for added scalp health. Highly recommend for hair growth without medicated products.Read less

    It works, but with a caveat
    I bought this because my scalp was red in spots and flakey. It has really helped in a very short time! One star was removed because it does cause my hair to be a little oily. I use a little dry shampoo to counteract but it would be nice if it didn’t do that. Or if I could use it as a before wash treatment a couple times a week.Read less

    I use it for my itchy scalp
    I really like this serum. I use it for my itchy scalp and it really helps soothe the itch. I also like that it’s water based so it’s not oily and my hair doesn’t look gross after I use it.
