Frequently Asked Questions

Q: What are keratin hair building fibers and how do they work?

A: Keratin hair building fibers are ultra-fine microfibers made from keratin — the natural protein found in human hair. When applied to the hair, these fibers use static electricity to bond to existing strands, instantly creating the appearance of thicker, denser, fuller hair. The LEWEDO 100g keratin fiber powder blends seamlessly with your natural hair color and texture for a realistic, salon-quality finish.

Q: Is this product suitable for all hair types and colors?

A: Yes! The LEWEDO Hair Building Fibers Powder is designed for all hair types — whether your hair is fine, thick, straight, wavy, or curly. It works for both men and women. Available in multiple shades, simply select the color closest to your natural hair for the most undetectable, blended result.

Q: How long does the 100g refill bag last?

A: The 100g refill bag offers significantly more product than standard-sized options, making it ideal for regular users. Depending on the frequency of application and the coverage area, a 100g bag can last several weeks to a few months. It has a 12-month period after opening for best results.

Q: Can I use this refill bag with my existing hair fiber applicator?

A: Yes — the 100g refill bag is designed to be transferred into your existing hair fiber applicator bottle or shaker bottle for easy, mess-free application. Simply refill your applicator as needed and continue using it as normal.

Q: Is this product safe to use?

A: Yes. The LEWEDO Hair Building Fibers Powder is CPNP (Cosmetic Products Notification Portal) certified and formulated without high-concern chemicals, making it suitable for everyday cosmetic use. As with all cosmetic products, avoid contact with eyes and keep out of reach of children.
