Works Without Build-up On Frizzy, Curly, Heat Damaged Hair
My hair has been looking a bit shabby since I've been heat treating too often. The more I wash it, the more heat my hair receives and since I don't like to go a week without washing (even though that is best for my hair), my hair will get very dry from excess washing and the blow out and flat iron ...

This left my hair feeling so soft and silky.
Not sponsored absolutely love

Best!
A good hair mask, does the job. If you have extremely dry hair this is a holy grail
Doesn't do anything
I much prefer the matrix food for soft over this. with the ouai fine to medium mask i cant even run my fingers through my hair, yet when i use the matrix food for soft its like magic.
Perfect
Love it! Also, i do not use the shampoo and conditioner from this brand. It works great still!

- Q
Can you leave the product on overnight?
- Asked by Jj
- Official Answer By OUAI - Brand EngageAbsolutely! To do so, we recommend making sure hair does not have any product on it first. Then, use a spray bottle to make your hair slightly damp. Apply from ends to mid-shaft. Use a wide-tooth comb to distribute through hair, and let dry for about 5 minutes. Place hair in a bun, use a sleeping bonnet if you like. Rinse in the morning and shampoo your scalp. Conditioner is optional.Was this answer helpful to you
