Key actives

• Glycerin (2.5%): a plant-based humectant — draws and binds water deep into the hair fibre for long-lasting hydration.

• Hibiscus Seed Extract: a curl-loving botanical that strengthens, softens and adds moisture.
• Amodimethicone: a smart silicone that smooths the hair surface and reduces frizz without weighing curls down.
• Cetearyl Alcohol + Behentrimonium Chloride: conditioning agents that detangle and soften.

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

1. Wash the hair with a sulfate-free shampoo (ideally the matching Curl Expression Shampoo).
2. Squeeze out excess water from the hair.
3. Apply a generous amount of the mask to the mid-lengths and ends — avoid the scalp.
4. Comb through with a wide-tooth comb or fingers to ensure even distribution.
5. Leave on for 5–10 minutes.
6. For an intensive treatment, cover with a shower cap and apply gentle heat (warm towel or hair-cap warming) for 15 minutes.
7. Rinse thoroughly with lukewarm water.
8. Use 1–2 times per week, depending on how dry the hair feels.
