Scalp Care

Your scalp is skin. And like any skin, it needs to be clean, balanced, and hydrated to do its job. When it's clogged with product buildup, irritated, or just dry, it creates a bad environment for hair to grow. A good scalp care routine really is what makes the rest of your hair routine actually work.

They’re products specifically designed to work on the scalp itself rather than the hair strands. OUAI Scalp Serum for example is a leave-in treatment you apply daily, a bit like a serum for your face, but for your head.

If your hair feels weighed down even right after washing, if your roots get oily weirdly fast, if your scalp itches or feels tight, or if your hair looks less full than it used to… those are all signs your scalp could use some attention. And even if none of those apply, using a Scalp Serum is just good preventive maintenance.

Shampoo cleans the hair. Conditioner smooths it. And the best scalp care products work on the skin underneath, balancing oil production, exfoliating dead skin, hydrating the scalp barrier, and in the case of our serum, actively supporting fuller-looking hair. They serve a completely different function. You can't swap one for the other.

Daily for the Scalp Serum (one dropper’s worth, massaged in, left in. AM or PM, wet or dry hair, up to you). Weekly (or twice weekly if you want an extra-clean scalp) for the Scalp & Body Scrub, applied before shampoo. The Serum is where commitment really counts, as users typically see results after 90 days of consistent daily use.

Yes. The Scalp & Body Scrub does an excellent job of deep-cleaning excess oil and the product buildup that makes roots look greasy. The Serum is a balancing formula, not a heavy one, so it absorbs quickly and doesn't add oil to the equation. 

Yes, our products for scalp care are safe for color-treated hair. They’re all free of SLS and SLES, which are the ingredients most likely to mess with color. 

Yes, in fact, OUAI Scalp Serum was tested in a 16-week clinical study, and 100% of users showed improvement in the look of fuller, thicker hair, and 90% showed improvement in scalp health. So, it’s no wonder it’s one of our best hair care products for a healthier scalp.
