What does “purifying” mean in a hair mask?
Purifying refers to helping remove buildup, rebalance the scalp and reduce flaking while still delivering deep hydration. Unlike heavy masks that only focus on moisture, this formula supports scalp health as well as hair softness.
How to use
After shampooing, apply a moderate amount of mask to hair and scalp. Leave on for 10–25 minutes depending on desired intensity. For deeper conditioning, wrap hair in a warm towel. Rinse thoroughly and style as usual.
