Pro Tip: When in doubt, order extra! Unused hair can be saved for touch-ups or returned if unused.
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.
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.
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.
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.
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.

I absolutely love this hair! I have had it in for almost 6 months now and it still holds its curl. I had them moved up at 3 months and they still looked brand new. The curls are beautiful and match my natural pattern so well. I am definitely purchasing more from this brand in the future.
Dear Justine, Your hair looks absolutely GORGEOUS! It is so good to hear that you have been using the hair for over 6 months now. It still looks absolutely beautiful. The way it blends perfectly with your natural hair is astonishing, you cannot even tell where your natural hair ends! Absolutely BEAUTIFUL!

Feel free to contact us with any questions or concerns at 1-888-290-4771 or e-mail us at support@perfectlocks.com. XO, Perfect Locks Team ❤️
These extensions have been my absolute favorite out of all the ones I’ve tried and match my hair texture and color perfectly!
Seriously the best hair in the market. I've been wearing fusion Exterminator since 2008 and have tried different vendors which were all alot more expensive. Most importantly, the curly texture matches perfectly with my hair and the hair stays in much longer!!! I had my last 134 pieces in for just over 8 months and did not lose one!! That had never happened, ever, in ten years. I've saved so much money by purchasing myself and having my stylist install them. Plus I know the hair is great quality, curls up, can be colored and will last.. I became a VIP member and saving even More! The customer service is very helpful and welcoming. I'm so glad I did my research and found Perfect Locks. Oh and what's really most important is that my hair stays in healthy shape. The tips are keratin glue which slide right off. I do not lose hair. As long as you detangle them during use you'll be good. I can twist, braid and party my hair and you won't even see the extensions in there.. if you're on the fence about trying utip fusions, I'd say this is the best quality to go with. It is very easy on the hair. Oh, and you will love it!!
Dear Sady, We appreciate your feedback so much! You are looking absolutely beautiful and definitely rocking those hair extensions! :) We strive to provide the highest quality of extensions and maintenance is definitely key. Please ensure you are using sulfate-free and paraben-free hair products to wash and condition your hair and that you are applying any necessary oils to keep the hair hydrated! Thank you again and we hope you keep being Team Perfect Locks!Perfect Locks Team ❤️
Second purchase of extensions from this company . Excellent , excellent, excellent. Hair came within one day . Beautiful texture and vrest staying power . As someone who needs curly extensions , perfect locks is a lifesaver
These are beautiful curly u-tip fusion extensions that my stylist put in for me. There STUNNING! They are the second set I have put in and as long as you take care of them properly you would be shocked at how long they can last! My own hair is curly so it matches very close if I just use a little product and I’m off and running! Also, sometimes I will braid them and air dry and it gives a whole different look. The color is beautiful and the curl stays curly unlike I have heard of other large brands. Sometimes I braid them and air dry and it gives a whole other look.I can straighten them if I like but this summer I’m embracing my curls! I love this company and product. This summer is easy with my BIG beautiful curls!
I just had them put in and I absolutely love them. I was nervous at first but they look exactly like my natural hair which is really curly. I am growing out a short hair cut and this helps tremendously! So glad I ordered from perfect locks! THEY ARE AWESOME.
hi I ordered wavy but I received curly and had to apply a keratin treatment to soften the curly hair as I really had to use them.The quality of tge hair is very good but it was a bit dissappointing to have received curly hair during a peak festive season.
even my hair dresser said that she loves my hair. Shocked by the sticker price but she knows that I only by the best, no matter the cost. Feels soft and flows like it was my real hair.
Most of the hair on my head is made up of these extensions. This is the best quality I've found. Highly recommended and a very reasonable price.
The best u tips fusion hair, so soft it's actual human hair in so excited that it has that curly texture and it can also be dyed what more do you want
My overall experience was fantastic! The hair I purchased is the curly 14" length and it is very good quality. Easy to install and doesn't tangle. After many washes the hair will regain the curls and stay loose, no tangle, and easy to manage. I will definitely buy the Fusion U-tip hair again.
I have been a loyal and consistent customer of Perfect Locks since 2014. I cannot say enough good things about the quality of the hair - I won't purchase from anyone else.
I’ve had these in for 2 months now and it’s amazing quality and I constantly am getting compliments on how beautiful my hair is and they think it’s my real hair!

The hair, color, and texture were perfect!! My only wish would be that the keratin tip was not so long. Half or a little more than that would be perfect. Great experience!
