What Is Keratin?

Keratin is a structural protein that makes up the majority of your hair's composition. Over time, heat styling, chemical treatments, and environmental exposure break down keratin, leading to frizz, breakage, and dullness. Replenishing keratin helps restore the hair's natural structure, giving it back its strength, smoothness, and shine.

How to Use – Daily Care

1. After washing your hair with shampoo, apply the hair mask to wet hair.
2. Work the product from the mid-lengths to the ends — avoid the scalp.
3. Leave on for 5–10 minutes.
4. Rinse thoroughly with warm water.

How to Use – Intensive Keratin Treatment

1. Blow-dry hair to 100% dry. Wash hair twice (chemically treated) or three times (virgin hair) with a Keratin Purifying Shampoo.
2. Shake the bottle well. Pour approx. 2–3 oz of Keratin Treatment into a bowl. Apply to hair with a brush, combing through each section until fully saturated. Wear gloves during application.
3. Place hair in a cap.
4. For chemically treated or damaged hair: allow 20 minutes absorption, then blow-dry to 100% dry. For very coarse or resistant hair: allow 30 minutes, then blow-dry.
5. Divide hair into 4 sections using a heat-resistant comb. With a flat iron at 450°F (230°C), take 1/8-inch sections from nape to front, passing the iron from root to ends 5–7 times (7–10 times for extremely curly/coarse hair). For chemically treated hair, reduce heat to 430°F (200°C).
6. After 72 hours (3 days), wash hair with a Keratin Daily Shampoo and Conditioner.

Frequently Asked Questions

Q: How often should I use the SADOER Keratin Hair Mask for best results?

A: For daily maintenance, you can use the keratin hair mask 2–3 times per week after shampooing. For an intensive keratin straightening treatment, apply as needed — the smoothing effects can last up to 3 months, so a full treatment every 2–3 months is typically sufficient for damaged or chemically treated hair.

Q: Is this keratin hair mask safe for color-treated or chemically processed hair?

A: Yes! The SADOER Keratin Hair Mask is specifically formulated to help protect color-treated hair after dyeing. It contains no high-concern chemicals and is safe for chemically processed, heat-damaged, and color-treated hair. It actually helps seal the cuticle to lock in hair color and extend vibrancy.

Q: What is the difference between the 30ml and 500ml sizes?

A: The 30ml size is perfect for trying out the product or for travel use, while the 500ml option is ideal for regular home use or salon-style intensive treatments. Both contain the same keratin-rich formula for repairing frizzy, damaged, or dry hair.
