Overview
Not a light weekly rinse, this IGK mask doubles as a rinse-out treatment and an intense leave-in for thick, frizz-prone hair. A plant butter concentrate, spirulina protein and a biolipid barrier smooth and detangle.
Leave-in use makes it a frizz tool between wash days, and the claimed multi-day control cuts styling time. The rich formula is aimed at coarse texture, so lighter hair types are not the target.
Who it's for
Medium to thick hair that needs taming overnight or between washes gets a flexible mask. Fine or oily hair should choose a lighter conditioner.
Pros and cons
- Rinse-out or leave-in
- Long-lasting frizz control claim
- Detangles and softens
- Vegan, sulfate free
- Too rich for fine hair
- Leave-in amount not specified
- Small jar for leave-in use
Performance notes
The butter concentrate coats mid-lengths and ends, and the biolipid barrier slows humidity from roughing up the cuticle. Leaving it in gives more control on coarse texture, while rinsing gives a lighter finish.
