Skin Benefits

Promotes a sleek finish and smoother styling with a lightweight afterfeel, leaving hair looking more polished from root to tip.

Uses in Skincare & Cosmetics

Turns up in leave-in sprays, milky lotions, hair milks, and styling creams.

Safety

May cause irritation for some, especially on sensitive scalps or with leave-on use. Avoid eye contact, and patch test first if you're prone to reactions.
