Flat keratin bonds #18, 70cm, 134g, 180 pcs. Premium category

1. Begin with clean, fully dry hair. Do not use oils, conditioners, or silicone-based products near the roots before installation.

2. Section the hair into clean horizontal rows and isolate a small, even strand of natural hair.

3. Place a protective shield near the scalp to keep the section clean and protect the skin during application.

4. Position the flat keratin bond underneath or beside the natural strand.

5. Use a professional fusion heat tool to gently melt the keratin bond. Avoid overheating the hair or applying excessive heat near the scalp.

6. Once the keratin softens, roll and flatten the bond with your fingers or shaping tool to create a thin, secure attachment that lays comfortably against the head.

7. Continue the installation strand by strand, maintaining balanced spacing and even weight distribution throughout the head.

8. After installation, blend and shape the extensions if needed for seamless movement and a natural finish.

9. Avoid washing the hair, excessive sweating, oils, or heat directly on the bonds for the first 24–48 hours.

10. Brush carefully while supporting the roots and use sulfate-free, extension-safe products to maintain the quality and longevity of both the hair and the bonds.
