Why Choose Our U Tip Hair Extensions Human Hair?
1. Undetectable Natural Blend & Lightweight Comfort
Each extension features an ultra-flat U-shaped keratin bond that lies close to your scalp, hiding seamlessly under natural hair. Made with 100% Remy human hair, the texture, shine, and movement match your own strands—no one will guess you’re wearing extensions. The slim bond design distributes weight evenly, so you’ll stay comfortable all day, even during workouts or long events.
2. Long-Lasting Durability & Damage-Free Wear
Our keratin bonds (made with skin-friendly, formaldehyde-free Italian keratin) fuse securely with natural hair using gentle heat. Unlike glue-in or low-quality tape-ins, they last 3–5 months with proper care—longer than most temporary extensions. The bond mimics your hair’s natural protein structure, minimizing breakage when installed or removed by a professional.
3. Versatile Styling for Every Occasion
Style these U tip human hair extensions just like your natural hair—curl, straighten, or dye them darker (avoid lightening to protect cuticles). They’re perfect for high ponytails, buns, or braids without visible bonds, making them ideal for weddings, dates, or everyday polished looks. Choose from solid shades, ombre, or balayage to match your style or add subtle highlights.
4. Suitable for All Hair Types (Including Thin Hair)
Whether you have thin, fine hair or thick locks, these extensions work beautifully. The lightweight bond won’t tug on thin hair, and 50–100g bundles add just the right volume without overloading strands. For full-head transformations, 150g bundles create lush length and density that looks completely natural.

Installation Guide for u tip hair extensions
Professional Installation (Recommended)
- Wash and dry natural hair thoroughly (no conditioner—clean hair helps bonds adhere).
- Section hair into 1–2cm wide strands, keeping sections neat and close to the scalp.
- Warm a keratin fusion tool to 160–180°C (320–356°F), adjusting for hair thickness.
- Place the U tip bond 1–2cm from the scalp (avoid direct contact) and clamp the tool over the bond for 3-5 seconds to melt keratin. Rub the section of hair with your fingers to wrap the hair extensions around your own hair.
- Hold the extension in place for 2–3 seconds to let the bond cool and set.
- Repeat, working from back to front, and brush gently to blend.
DIY Tips for Experienced Users
- Use a mini fusion tool for better control at home.
- Start with 50–100g bundles if you’re new to DIY application.
- Avoid overheating the bond—this can damage natural hair or weaken the fusion.
Removal & Care Guide
Gentle Removal Methods
- Professional Removal: Apply keratin bond remover to soften the bond, wait 1–2 minutes, then gently twist and separate with pliers (no pulling).
- At-Home Removal: Soak bonds in coconut/argan oil for 15–20 minutes, then gently comb apart with a wide-tooth comb.
- Post-removal: Shampoo twice to remove residue and condition hair to restore moisture.
Maintenance for Longevity
- Wash every 2–3 days with sulfate-free shampoo; lather gently and rinse with lukewarm water.
- Pat dry with a towel (don’t wring) and air-dry when possible—use low heat if blow-drying.
- Brush with a loop brush or wide-tooth comb, starting from the ends and working up to roots.
- Apply heat protectant before styling; keep heat tools 15cm away from bonds.
- Sleep with hair braided or in a loose ponytail; use a silk pillowcase to reduce friction.
- Avoid chlorine, saltwater, and excessive sun—wear a swim cap when swimming and rinse immediately after.
