OUAI Hair Mask

By Jamie Lin, Reviews Editor||How we test

Celeb-approved mask with shea butter, avocado oil, and marshmallow root for silky, frizz-free hair.

OUAI Hair Mask has earned its celebrity following through genuine performance rather than clever marketing. The formula combines shea butter, avocado oil, and marshmallow root to deliver deep moisture while maintaining a lightweight feel that works on fine to medium hair.

We tested this on medium-thickness hair prone to frizz and found it excellent at taming flyaways and adding a beautiful, natural-looking shine. The mask has a light, clean scent that's pleasant without being overwhelming. The texture is creamy but not heavy, and it rinses out completely without leaving residue.

At current pricing for 8 oz, it's a premium purchase but competitive with other luxury masks. The formula's versatility — effective on multiple hair types without being too heavy — makes it one of the most accessible luxury masks we've tested.
