OUAI Thick Hair Shampoo Eucalyptus Rosemary 10 fl oz

Salon-Worthy Thickness and Shine for Hair That Demands More

If you already know what OUAI can do for thick hair, you know why restocking is non-negotiable. This is the shampoo that actually meets thick hair where it is — not where other formulas wish it were.

Thick hair has its own set of challenges: it weighs down easily, resists detangling, and can look dull no matter how often you wash it. A formula that deeply moisturizes and detangles without stripping colour or leaving residue is harder to find than it should be. When you finally find one that also strengthens hair and helps fight frizz, you hold onto it.

The OUAI Thick Hair Shampoo 10 fl oz is built around a keratin and oat peptide-infused formula that works from root to tip — reinforcing each strand while smoothing the cuticle. It functions as a color safe shampoo for thick hair, meaning your tone stays true wash after wash. This full-size 10 fl oz bottle is a sulfate free shampoo that lathers richly without the harsh stripping agents that leave thick hair feeling rough and tangled. Shea butter, avocado oil, and marshmallow root extract work together in a deeply conditioning blend that leaves hair manageable, visibly shinier, and noticeably stronger over time.
