Mielle Rosemary Mint Strengthening Hair Masque is a deep-conditioning hair treatment for dry, brittle hair, formulated with biotin and rosemary and peppermint oils to help nourish and strengthen strands. The formula blends plant oils and butters — including sweet almond, sunflower, olive, shea, coconut, and babassu — with botanical extracts like rosemary, chamomile, comfrey, hops, and nettle, plus honey, to help restore softness and shine to dry or damaged hair.
After shampooing, the masque is smoothed evenly through damp hair from roots to ends, left in for 15 to 20 minutes, then rinsed thoroughly. Mielle markets the Rosemary Mint line as suitable across a range of textures and safe for chemically treated hair.
