Argan oil hair treatments are sold in several forms, most commonly creams, serums, and straight oils.
Argan oil creams commonly advertise hydration and moisture, smoothing and frizz control, enhanced shine, damage repair and strengthening, softening, and general conditioning.
Leave‑in creams are typically applied to damp hair and not rinsed. Deep conditioners or masks are used after shampooing, left on for a few minutes (often about 3–5 minutes), then rinsed. Oils and serums can be applied to wet, damp, or dry hair and used before blow‑drying or after styling.
Several items claim multi‑day frizz control—commonly up to 72 hours or “up to 3 days” when used with the full system—and report resistance to very high humidity (examples note protection up to about 97% humidity).
