What Is Keratin?

Keratin is a naturally occurring structural protein found in every strand of your hair. Heat styling, chemical treatments, and environmental stress can strip hair of its keratin over time, leading to dullness, breakage, and frizz. This mask replenishes that lost protein, helping to rebuild each strand from the inside out.

How to Use — Daily Care

1. Wash hair with your regular shampoo.
2. Apply the mask to damp hair, working from mid-lengths to ends. Avoid the scalp.
3. Leave on for 5–10 minutes.
4. Rinse thoroughly with warm water.

How to Use — Full Keratin Treatment

1. Prep: Blow-dry hair completely. Wash twice with a clarifying/keratin purifying shampoo (chemically treated hair) or three times (virgin hair).
2. Apply: Shake bottle well. Pour 2–3 oz into a bowl and apply evenly with a brush, combing through each section until fully saturated. Wear gloves during application.
3. Process: Place hair in a cap. Allow 20 minutes for chemically treated or fine hair; 30 minutes for resistant or coarse hair. Blow-dry to 100% dry.
4. Flat Iron: Divide hair into 4 sections. Using a flat iron at 450°F (230°C) — or 430°F (220°C) for chemically treated strands — take 1/8-inch sections from the nape upward. Pass the iron slowly from root to ends 5–7 times (7–10 times for very coarse or curly hair).
5. Wait: After 72 hours (3 days), wash with a keratin-safe shampoo and conditioner.
