U-tip extensions use individual keratin bonds shaped like a small nail to attach seamlessly to your natural hair. With the right care routine, these bonds stay secure and the hair stays beautiful for months.
How U-Tip Bonds Work
Each strand is attached to a small section of your natural hair using heat to fuse the keratin tip. The bonds are strong and secure, but they can be weakened by oil, certain chemicals, and excessive heat. Your care routine should focus on keeping the bonds intact while maintaining the quality of the extension hair.
The First Few Days
Give your bonds 48-72 hours to fully set before washing. Avoid heavy sweating, steam, swimming, or getting your hair thoroughly wet during this time. If you need to freshen up, you can use dry shampoo on your scalp only.
Washing
Wash every 2-3 days to balance keeping your scalp clean without stripping moisture from the extensions. When washing, keep your head upright and let water flow down from your scalp. Never flip your head upside down - this tangles the extension hair around the bonds, creating mats that are painful to remove and can damage your natural hair.
Apply sulfate-free shampoo to your scalp and gently massage with your fingertips. Let the suds run through the lengths as you rinse - don't scrub or bunch the hair at the mid-lengths where your bonds are located. Follow with a lightweight conditioner on the ends only, staying at least 2 inches below the lowest bonds. Heavy conditioners near the bonds can cause them to slip.
Rinse extremely thoroughly. Take longer than you think you need - any residue near the bonds weakens them over time.
Drying
Squeeze water out gently with a soft towel. Never rub or twist the hair. Air drying is ideal, but if you need to blow dry, use low to medium heat and keep the dryer moving. Don't concentrate heat on any one area, especially near the bonds - prolonged high heat can soften keratin.
Most importantly, never sleep with wet hair. Moisture trapped at the bonds overnight can make them gummy or cause slippage.
Brushing
This is the most important thing you can do for your U-tip extensions. Brush at least 2-3 times daily with a loop brush or extension-safe brush. The loops are designed to glide over the bonds without snagging, while still detangling the hair.
Focus extra attention on problem areas: the nape of your neck, behind your ears, and the underneath layers where hair naturally tangles. Hold the hair near the bonds with one hand while brushing with the other so you're not pulling on the attachment points.
Always brush dry or nearly-dry hair. Start at the ends and work up in small sections, never pulling through tangles. Before bed, do a thorough brushing session and then secure hair in a loose braid or low ponytail.
What Damages Bonds
Keep away from the bonds: oils (including argan, coconut, and other hair oils), products with sulfates, products with alcohol, heavy conditioners and masks, and prolonged exposure to chlorine and salt water.
Safe to use: sulfate-free shampoo, lightweight leave-in conditioner on ends, heat protectant spray, water-based styling products, and dry shampoo on scalp only (alcohol-free formulas).
Heat Styling
Your U-tip extensions can absolutely be heat styled - they're 100% human hair. Use heat protectant before any hot tools, and keep temperatures at 300-350 degrees. The one caution is to avoid clamping hot tools directly on the keratin bonds. The bonds can handle incidental heat, but a flat iron clamped directly on a bond will soften and potentially melt it. Stay at least an inch above the bond when straightening or curling.
Swimming and Sweating
Chlorine and salt water aren't great for keratin bonds. If you swim, wet your hair with clean water first and apply a leave-in conditioner to create a barrier. Keep your hair braided and above water as much as possible. Rinse immediately after and wash with a clarifying shampoo.
For workouts, pull hair back in a low braid or ponytail. After exercising, let your hair and scalp dry completely before putting it back up - sweat trapped at the bonds can cause them to break down.
Sleep Routine
Always brush thoroughly before bed, then secure in a loose braid or soft ponytail. Avoid anything tight that pulls on the bonds. Sleep on a silk or satin pillowcase - the smooth surface creates less friction than cotton, preventing tangles and reducing stress on the bonds.
Checking Your Bonds
Every few days, run your fingers along your bonds to check their condition. Healthy bonds feel firm and smooth. If any feel soft, sticky, or loose, contact your stylist - catching a slipping bond early can prevent hair loss.
Maintenance and Removal
U-tip extensions typically last 3-4 months before needing removal and reinstallation. As your hair grows, the bonds move down, becoming more visible and putting stress on your natural hair. Stick to your stylist's recommended timeline.
Never attempt to remove bonds yourself. Cutting, pulling, or using household products can seriously damage your natural hair. Your stylist will use a professional keratin bond remover that dissolves the bonds safely, leaving your natural hair undamaged and ready for a new set if desired.
U-Tips Advised Quantity
| Desired Results | Fine Density | Medium Density | Thick |
|---|---|---|---|

Every head of hair is unique, and the right amount depends on:
- Wear Time - Temporary or long-term?
- Installation - Subtle blend or full volume?
- Lifestyle - Low-maintenance or high-glam?
- Hairstyle - Natural look or bold transformation?
- Budget - Invest in quality for lasting beauty.
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 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.
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!

Hello Gorgeous, We are very happy to hear that you love us as much as we love having you as a customer. XO, Perfect Locks Team ❤️
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!!
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.
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 !
I love my hair!! I can install it myself saving 100’s of dollars.
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.
Excellent. Great product. Would buy again.
The hair I received was beautiful! And the customer service was amazing, I will be purchasing again :)
