A hair mask is a deep conditioning treatment that repairs what shampoo and regular conditioner can't. Applied once a week for 20-30 minutes, a good mask rebuilds keratin, restores moisture, and significantly reduces breakage.
WOW's bestselling mask combines Onion (sulphur-rich for keratin), Black Seed Oil, and deep conditioning agents. Weekly use significantly reduces breakage and improves hair texture over 4-6 weeks. Apply on damp hair after shampoo, leave 20-30 minutes.
