Follow our 3-step routine for visibly stronger hair.
The Keratin Repair mask is the 3rd step of the routine:
Once or twice a week, apply after bathing for 3-5 minutes and rinse with plenty of water.
For even more enhanced action, apply to well-dried hair, wrap with a warm towel, leave the mask for 15 minutes and then rinse.
Avoid eye contact. For external use only.

Additional tips:
Use a hair mask 1-2 times a week, or based on your needs.
Apply the mask only to the lengths and ends of the hair avoiding the root, always rinsing very well.
Avoid very hot water to rinse your hair as it can irritate the scalp.
Brush your hair gently (prefer a brush with natural bristles).
To reduce damage, limit heat styling which damages and dehydrates the hair.
