Our U-Tip (Nail Tip) Extensions are the gold standard for hot fusion keratin bonding, crafted from 100% Vietnamese virgin human hair. Each pack contains 100 pre-bonded strands (50g) with a U-shaped keratin tip that fuses directly to natural hair using a heat connector tool.

💧 Care Instructions
- Wait 48 hours after installation before the first wash to allow bonds to fully set
- Wash with sulfate-free shampoo — avoid applying directly to the bonds
- Use a lightweight conditioner from mid-length to tips only

- Schedule removal and reinstallation every 4-6 months with a certified stylist

Laura Garcia –
I have been doing hot fusion extensions in Madrid for 12 years and these U-tips are the cleanest keratin bonds I have worked with. The 24-inch straight strands fuse perfectly at 175 degrees and the bonds come out tiny and flat. My clients wear them for five months without a single complaint.

I supply salons across Accra and Kumasi with extensions and the Azy Hair U-tips have the highest reorder rate of any product I stock. The 20-inch straight is our flagship and stylists tell me the bonds hold better than any Italian or Chinese keratin tips they have tried before.
Lena Johansson –
Bought 200 strands of the 22-inch for my own hair at my apartment in Stockholm. My stylist said the keratin quality is excellent — melts smoothly without any bubbling. Four stars only because I noticed slight variation in strand thickness between two packs but the overall look is gorgeous.
