Hair Care

Hair that looks good and hair that is good are different things. Our hair care products are built around both. The shampoos, conditioners, treatments, and styling products in this collection all exist because hair isn't one-size-fits-all, and "works for all hair types" usually means works for nobody in particular.

Fine hair that’s flat by midday. Thick hair that turns blow drying into a workout. Curly hair that goes one way on Tuesday and another on Thursday. OUAI gets it, and our professional hair care products are ones that actually understand what your hair does.

Hair Care Products FAQs

What hair care products do I need for a healthy routine?

Less than you think. The non-negotiables: a shampoo that matches your hair type, a conditioner applied mid-lengths to ends, and something to protect your strands post-shower (OUAI Leave In Conditioner is the go-to — it does about five jobs at once). From there, a weekly treatment masque and whatever styling products you actually need. That's it. A great hair care routine isn't about owning twenty products. It's about owning the right ones.

How do I choose the right hair care products for my hair type?

Start with thickness (fine, medium, thick) and texture (straight, wavy, curly, coily). Those two answers determine almost everything else. OUAI shampoos and conditioners are labeled by hair weight, so you're not decoding a label that says 'moisturizing' and hoping for the best.

How often should I wash my hair?

As often as your hair actually needs it, not as often as some rule says you should. Fine hair tends to get oily fast and often likes every-other-day washing. Thick, curly, and coily hair holds its natural oils much longer and usually thrives on once a week. Washing too often strips the scalp of oils it actually needs, which triggers more oil production. The irony. The Detox Shampoo once a week handles a deep reset for any hair type.

What's the difference between hair care products and styling products?

Hair care products (shampoos, conditioners, treatments…) work on the health and structure of your hair. They cleanse, nourish, and strengthen. Styling products shape, hold, or finish the look. Both matter, but they operate at different stages: hair care first as the foundation, styling last to direct the result. 

Do I need to use conditioner after every shampoo?

Yes, for nearly every hair type. Shampoo opens the cuticle to lift out oil and dirt; conditioner closes it back down, smooths the surface, and replaces the moisture that shampooing strips. Skipping it causes frizz, breakage, and hair that's just harder to deal with.

Can hair care products help with damaged hair?

Absolutely, and the right ones make a serious difference. OUAI Bond Repair Balm reverses hair damage in 3 minutes (clinically tested). The Treatment Masques restore moisture and strengthen with keratin, shea butter, and panthenol. The Leave In Conditioner protects against heat damage up to 450°F and reduces breakage by 52% when used with heat tools. 

How can I build the best hair care routine?

Start simple. Shampoo matched to your hair type, conditioner on mid-lengths to ends, Leave In Conditioner for protection and hydration. Add a treatment masque once a week. If fuller hair is a goal, layer in the Scalp Serum daily. Add styling products based on what you're going for. Then: leave it alone and be consistent. The best routines are the ones you actually stick to.

Why is consistency important in hair care?

Because hair takes time. Most products don't work overnight (they build results over weeks of regular use). The Scalp Serum takes 90 days to show its full effect, as damaged hair needs sustained repair. The boring basics (wash, condition, protect) done consistently are much better than a complicated routine that only happens when you remember. Pick the routine you'll actually do.
