How are U-Tip hair extensions applied?

The u-tip fusion hair extensions are applied using a heated tool that melts the keratin bond, which is then attached to a small section of the natural hair. The process involves taking small sections of hair and attaching a u-tip extension to each section, the tip has to be heated and wrapped around each small section of hair. This can be time-consuming and requires a skilled technician.

How long do U-Tipped extensions last?

U-tip fusion hair extensions can last anywhere from 3 to 6 months with proper care and maintenance. However, it is important to note that regular maintenance is required to keep the extensions looking their best. Clients will need to go in for regular touch-up appointments to have any loose bonds tightened or replaced and to ensure that the extensions are properly aligned with the natural hair. Neglecting maintenance can cause the extensions to become tangled, matted, or even fall out prematurely.

Can U-Tip fusion hair extensions be reused?

U-tip fusion hair extensions can be reused if the extensions are still in good condition and the keratin bonds are intact. The extensions are removed using a special solvent that breaks down the keratin bond, and new bonds can be applied to the extensions for reuse.

Are U-Tipped extensions suitable for all hair types?

U-tip fusion hair extensions are suitable for most hair types, but they may not be suitable for extremely fine or thin hair. The weight of the extensions can put too much stress on the natural hair and cause damage. It is important to consult with a hair extension technician to determine if u-tip fusion extensions are suitable for your hair type.

How to InstallQuick step-by-step application guide

1. Sectioning & Preparation 3 min

Start by sectioning the client’s hair into clean, horizontal rows, beginning at the nape of the neck. Ensure the hair is completely dry and free of oils or product buildup for maximum hold.

2. Bead Placement 2 min

Use a loop tool to thread a silicone-lined bead onto a small section of natural hair. Slide the bead up close to the scalp, leaving a small gap (about ¼ inch) for natural movement.

3. Insert the I-Tip Extension 1 min

Insert the I-Tip extension into the bead, ensuring the tip is fully enclosed within the bead. Avoid overlapping too much natural hair, as this can cause slipping.

4. Securing the Beads 1 min

Use a professional crimping tool to clamp the bead securely, locking the extension in place. Repeat the process row by row, maintaining even spacing for a seamless, natural blend.

5. Repeat and Blend 10 min

Once every extension is installed, brush gently to blend them into the natural hair. Tell the client to keep oil-based products away from the beads and to book a maintenance appointment every 6 to 8 weeks as the bonds grow out.

Professional Installation Recommended

This method is best installed by a licensed stylist to ensure proper placement and protect the health of your natural hair. Looking for a stylist experienced with extensions? Find a Pro Stylist near you.

Pretty hair

I like that the extensions look natural. People think it is my natural hair. I have naturally wavy hair and i like the wavy extensions because they really blend with my natural hair, other ones I tried were too wavy or too curly. But these are nice. Wish they were a little thicker though.

Best Extensions

I have officially made the switch from tapes to fusion. This wavy texture matched my hair perfectly. The u tip fusion method has so far worked best for blending with my very fine and very little bit of hair. It’s been over a month and they feel more comfortable than the tapes (sorry). Which means that I will be buying more hair because I can’t live without how good these extensions make me feel!

The best hair!

I ordered 26' 1B curly hair, out of the ten years I have been wearing extensions this is by far the best quality I have ever had. Unlike some hair that claims to be curly, and goes straight after once wash, this hair actually stays curly. It looked even better after I washed it. It is extremely soft and doesn't tangle at all. A little on the pricey side but sooo worth it! It shipped extremely fast. I will definitely order from them again. So happy with the whole experience!!

Curly hair? The best

I have done extensions services for nearly 40 years and have yet to come across curly hair as care free, consistently good quality as here.

Amazing quality !

I’ve been using Hair extension for 8 years and it was my first time trying perfect locks , the hair is so thick and has amazing quality that last which is hard to find these days . Im definitely sold on perfect locks !

Perfect !! Thick from top to bottom !

I love my hair!! I can install it myself saving 100’s of dollars.

Great Hair!!

I love this hair and the tips are awesome! Very happy with purchase. My only problem is someone has to sign for them when delivered. I am never home during the day. Kinda stressful. I understand why but some people have a long day.
