Description:
The Cysteine Smoothing Treatment is one of the safest hair treatments on the market to restructure, soften, and relax curls. It reduces curl volume, leaving hair straighter, smoother, and more manageable. The formula is naturally absorbent and contains no harmful substances, helping to straighten and strengthen hair. Enriched with Keratin and Argan Oil, it moisturizes, repairs damaged hair, and protects your hair’s natural shine and beauty.

Directions:

1. Wash hair 1–2 times with Keratin Deep Cleansing Shampoo to remove residue, cleanse, and open the cuticle.

2. Towel dry to remove excess water.

3. Apply the Cysteine Smoothing Treatment using a fine-tooth comb, distributing evenly from the nape upward.

4. Leave on for 25 minutes, then rinse thoroughly (do not use shampoo).

5. Blow-dry the hair completely.

6. Using a flat iron, straighten the hair starting from the nape, section by section.

7. Finish by sealing with Keratin Protein Repairing Shine Mist for added shine and protection.
