If you caught my thoughts on the Ouai St Barts range, it won’t shock you to learn that I’m fully on board with their haircare too. I first tried the Ouai Medium Hair Shampoo and Conditioner via two generous samples on a weekend trip to London, and loved them at first use. When my Redken shampoo and conditioner ran out, I didn’t hesitate to go full-size.
What I like about Ouai is the ease – you pick your shampoo and conditioner by hair type: Fine, Medium or Thick. No faffing or trying to self diagnose hair conditions. My hair, once solidly in the Thick camp, has mellowed into Medium territory over the years, so that’s what I went for.
The bottles are sleek, minimal and look properly smart in the shower. But the standout here is the fragrance which the brand name the Mercer Street fragrance. It’s a beautifully balanced blend of Italian lemon, Turkish rose, jasmine sambac, iris, lily, and white musk. It smells like an expensive salon.
🤍Ouai Medium Hair Shampoo
A satisfying lather that strikes the right balance between clean and conditioned. It doesn’t strip, doesn’t dry, and leaves hair feeling light, soft and frizz-free thanks to a blend of keratin, kumquat extract, babassu and coconut oils.


🤍Ouai Medium Hair Conditioner
Equally impressive – silky without being heavy, hydrating without greasiness. It rinses clean and leaves no tell-tale residue, which is no small feat for something this moisturising.


Together, they leave my hair feeling properly clean and touchably soft – never squeaky, never straw-like. They’ve slotted seamlessly into my routine.
Good haircare should be simple and effective. This range hits both points spot on.
