OI Oil

from £31.50

Multi-purpose hair oil to smooth frizz, boost shine and hydrate

This is the finishing touch that makes all the difference. OI Oil is a lightweight, multi-purpose hair oil that delivers instant softness, glossy shine and long-lasting frizz control, without leaving hair feeling heavy. Just a few drops smooth the lengths, improve manageability and give hair that polished, healthy look.

Powered by antioxidant-rich Roucou oil, it helps protect hair from environmental stress while gently hydrating and sealing the cuticle. Ideal for dry, frizzy, curly or colour-treated hair, and especially good for medium to coarse textures. Use it before styling for softness and control, or after for shine and definition. Finished with the signature warm OI fragrance, it leaves hair silky, radiant and beautifully put together.

Why we love it

  • Controls frizz and adds instant shine

  • Softens, hydrates and improves manageability
