Why Asian Stylists Recommend It
Dense, humidity-prone Asian hair reverts and frizzes after styling; a heat-activated smoothing leave-in seals the cuticle during drying so the sleek finish holds, which a rinse-out conditioner cannot.

Avoid if
Skip if your hair gets oily quickly or you dislike a soft, coated finish.
Why we recommend it
ReFa's Lock Treatment is a heat-activated leave-in that smooths and protects hair during blow-drying — a cream counterpart to the Lock Oil for thick, coarse Asian hair. Applied to damp lengths before heat, it uses the dryer's warmth to help seal the cuticle, tame frizz, and hold a smooth, glossy finish longer through a humid day, with heat protection built in. It suits dense, humidity-prone hair that reverts after styling, and it stays off the fine roots so it does not weigh hair down. Smooth it through damp mid-lengths and ends, then blow-dry. It preps and smooths for the blow-dry rather than deeply repairing — a heat-activated smoothing leave-in, ideal with a ReFa tool.
