Who it's for
Curl Expression Hair Mask is for anyone with curly, wavy or coily hair — types 2A through 4C. Particularly well-suited to dry, dehydrated and frizz-prone curls, and to those who heat-style or have chemically treated curls. A natural pair with the matching Curl Expression Shampoo and Conditioner for a complete curl-care routine. The generous salon-size makes it ideal for committed users, professional stylists, and salon back-bar use.
How to use
- Wash the hair with a sulfate-free shampoo (ideally the matching Curl Expression Shampoo).
- Squeeze out excess water from the hair.
- Apply a generous amount of the mask to the mid-lengths and ends — avoid the scalp.
- Comb through with a wide-tooth comb or fingers to ensure even distribution.
- Leave on for 5–10 minutes.
- For an intensive treatment, cover with a shower cap and apply gentle heat (warm towel or hair-cap warming) for 15 minutes.
- Rinse thoroughly with lukewarm water.
- Use 1–2 times per week, depending on how dry the hair feels.
