Davines OI All In One Milk

The spray I hand to people who ask what they should be using before they blow-dry.

It's a light leave-in that does several jobs at once — detangles, controls frizz, adds softness, and protects from heat. That combination is why it's the one product in the range most people end up keeping.

What you'll notice

A comb goes through wet hair without fighting. Hair dries smoother and frizz is noticeably calmer, especially in damp weather. It's light enough that it doesn't build up, and it carries the OI scent.

Who it's for

Most hair types, and particularly useful if you blow-dry or use irons regularly. Fine hair can use it without going flat, which is the main thing that separates it from heavier leave-ins.

Who it's not for

If your frizz is severe or your hair is coarse, this alone won't hold it — you'd want OI Hair Butter in the wash, or OI Oil on top. This is control, not heavy smoothing.

How to use it

Spray through towel-dried hair, mid-lengths to ends, and comb through. Don't rinse. Then dry as normal. A few sprays is enough on most heads.

Available in 50ml (travel) and 135ml.
