U-Tip hair extensions use a "heat fusion traceless" method, melting keratin to fix hair bundles onto real hair.

• 1 Cleaning and Zoning: Wash and dry hair with clear shampoo (no conditioner). Start horizontal zoning above the neck.
• 2 Hair Retrieval Positioning: Select a small strand of real hair as thick as the extensions, placing the U-Tip bundle under it, 0.5-1 cm from roots.
• 3 Heating Fusion: Use a hot melt hair connector to soften and melt the U-shaped keratin atop the bundle.
• 4 Kneading and Shaping: Knead the keratin quickly before it cools, wrapping it around real hair to form a cylindrical joint.

• ! Durability: Lasts 3-5 months. Disassemble or reconnect promptly if it grows to prevent tangling.
• ! Nursing Restrictions: Avoid rubbing contact points when washing hair. Keep roots from high heat or hair oil to prevent loosening.
