Master Fusion I-Tip Methods
$159, free with Pro
-
1
Sectioning & Preparation3 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 Placement2 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 Extension1 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 Beads1 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 Blend10 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.
- Use a loop tool for faster bead threading
- Crimp beads flat, not round - flat sits closer to scalp
- Space bonds evenly for natural weight distribution
- Keep bonds at least 1cm from the scalp
- Check crimp tightness by gently tugging each strand
For textured hair, use the cold fusion (bead) method rather than heat bonds. Thread natural hair through the bead, insert the I-tip, and crimp flat. No heat damage to natural curl pattern.

I-tip extensions use small, individual keratin bonds to attach to your natural hair - creating incredibly natural movement and versatility. These bonds require specific care to ensure they last their full lifespan without slipping or damaging your natural hair.
Understanding Your Bonds
Each I-tip strand is attached using a small keratin bond about the size of a grain of rice. These bonds are strong but can be weakened by heat, oil, and certain ingredients. Your care routine should focus on keeping the bonds secure while maintaining the beauty of the hair.
The First 48-72 Hours
Don't wash your hair for at least 48-72 hours after installation. This allows the bonds to fully set. Avoid sweating heavily, swimming, or getting your hair wet during this time. If you absolutely must get your hair wet, keep it to a quick rinse without any products.
Washing
Wash your hair every 2-3 days - not daily, which can dry out both the extensions and your natural hair, but not less frequently, which allows oil buildup to break down the bonds. When washing, stand upright in the shower and let the water run down from your head. Never flip your head over, as this tangles the strands around the bonds.
Use a sulfate-free shampoo and focus on your scalp, gently massaging with your fingertips. Let the shampoo rinse through the lengths - don't pile the hair up or scrub the mid-lengths where the bonds are located. Follow with a lightweight conditioner on the ends only, at least 2 inches below the bonds. Heavy conditioner near the bonds can cause them to slip.
Rinse extremely thoroughly. Any product residue near the bonds weakens them over time.
Drying
Gently squeeze water out with a soft towel - never rub or twist. Let your hair air dry whenever possible. If you need to blow dry, use a low to medium heat setting and keep the dryer moving - don't focus heat on any one spot, especially near the bonds. High, concentrated heat can soften and damage keratin.
Never go to sleep with wet hair. The moisture gets trapped at the bonds and can cause them to become gummy or slip.
Brushing
Brush your extensions at least 2-3 times per day with a loop brush or soft-bristle extension brush. This is crucial for preventing matting at the bonds. The areas that need the most attention are the nape of your neck, behind your ears, and anywhere hair naturally rubs against itself or your clothing.
Always brush dry or nearly-dry hair - wet hair is more fragile and stretches more easily. Hold the hair near the bonds with one hand while brushing with the other to avoid pulling on the attachment points. Start at the ends and work up in small sections, gently working through any tangles.
At night, do a thorough brushing before bed. Secure your hair in a loose braid or soft ponytail to prevent tangling while you sleep.
Products to Avoid
Stay away from products containing oil, alcohol, or sulfates near your bonds. This includes most volumizing products and many dry shampoos, argan oil and other hair oils (use only on ends, well below bonds), any conditioner or mask applied near the roots, and products containing ethyl alcohol or other strong alcohols.
Safe products include sulfate-free shampoo, lightweight leave-in conditioner (ends only), heat protectant spray, water-based styling products, and alcohol-free dry shampoo on the scalp only.
Heat Styling
You can curl, straighten, and blow dry your I-tip extensions without issue - they're 100% human hair. Always use heat protectant before styling. Keep tools between 300-350 degrees and avoid direct contact between hot tools and the keratin bonds. The bonds can withstand incidental heat, but clamping a flat iron directly on a bond can cause it to soften or melt.
Swimming and Exercise
Avoid submerging your bonds in chlorinated or salt water for extended periods. If you swim, wet your hair with clean water first and apply a leave-in conditioner as a protective barrier. Wear your hair in a braid and keep it above water when possible. Immediately after swimming, rinse thoroughly and wash with clarifying shampoo.
For workouts, secure your hair in a low braid or ponytail. After exercising, let your scalp and bonds dry completely before putting your hair up - trapped sweat can break down the keratin.
Sleeping
Always brush before bed and secure your hair in a loose braid or low ponytail. Sleep on a silk or satin pillowcase to reduce friction. Avoid tight ponytails or buns that put stress on the bonds.
Maintenance and Removal
I-tip extensions typically last 3-4 months before needing removal and reinstallation. As your hair grows, the bonds move further from your scalp, which can make them visible and put stress on your natural hair. Don't try to extend the wear time beyond what your stylist recommends.
When it's time for removal, always have it done professionally. Your stylist will use a bond remover solution to safely break down the keratin without damaging your natural hair. Never try to pull, cut, or remove bonds yourself.
Checking Your Bonds
Between appointments, periodically check your bonds by gently running your fingers along them. If any feel loose, overly soft, or if you notice unusual shedding, contact your stylist before your scheduled maintenance.

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.
The diameter of the tips on perfect locks fusion i-tips is 3.5mm. This size is specifically designed to work with the majority of beads, both silicone and aluminum.
We include 25 strands in each pack of fusion hair.
The number of packs of fusion i-tips you will need to purchase will depend on several factors, such as the desired length, thickness, and volume you want to achieve, as well as the density and length of your natural hair. As a general rule of thumb, for a full head installation, we recommend 4 to 6 packs of fusion i-tips for hair that is of average thickness and length. However, if you have thinner or shorter hair, you may require fewer packs, while thicker or longer hair may require more packs. We always recommend consulting with a professional stylist to determine the appropriate amount of fusion i-tips for your specific hair needs.
If your fusion i-tips are slipping out of your hair, it may be an indication of several issues. Firstly, it could be that the extensions were not installed correctly, causing the keratin bond to not adhere to your natural hair properly. Secondly, it may be due to the natural shedding process of your hair, causing the bond to loosen and the extensions to fall out. Additionally, if you're not using the recommended aftercare products or if you're using heat styling tools excessively, this can also weaken the bond and cause slippage. Lastly, some hair conditioners are known to weaken the bond of the keratin, so when shampooing and conditioning, we advise not to apply product directly near the root.

The quality on day 3 of installation seems great. The hair looks and feels wonderful and the color is perfect. My stylist and I both noticed some of the tips are slightly different sized. Like maybe they are hand bonded rather than machine bound. The total amount of hair per bond is identical but some bonds have more glue than others. This isn't a deduction from their high quality just something we noticed.

The texture and softness of the hair is amazing totally love it although disappointed with the bond especially with as much as you pay for such little hair. I put mine in and within a week they were already coming out and I dont mean a couple as well you could not refuse them either which is a first.
Dear Kennita, I am sorry to hear that you are saying that your I-Tips did not last. May I ask how they were installed? Installation would be the problem with them only lasting that one week. Did you have any problems with the texture of the quality of the hair?, Perfect Locks Team ❤️
Love love love the itips so much better than previous brand I used.

Please be sure to tag us in any photos we'd love to feature you all on our website and/or social media platforms. XO, Perfect Locks Team ❤️
I am bummed because it’s really hard to find 26” I tip extensions so I was excited. They were 1/2 the hair volume as other Itips I’ve purchased so I would have needed twice as many, and only about 50% of it reached the full 26”. It got so thin at the bottom, I had to cut 3inches off after paying extra for the length. Also, they’re not even remotely straight once washed. Def disappointed.
So glad I invested in these extensions... They have given me the results I was looking for. Alba is wonderful to work with!
Hey Gorgeous, We are even happier that you have chosen us to help you achieve this look. That's what makes us happy, I'm thrilled to hear that the extensions are a good investment. Thank you for taking the time to write this, it is highly appreciated, Perfect Locks Team ❤️
I love the texture and quality of the hair.

This is the first time I've tried the I-tips from perfect locks, and they are absolutely fabulous! I'll never buy hair from anywhere else again. The quality is uncomparable. The hair lasts FOREVER and doesn't end up tangling and matting like other so-called "premium" brands. Thank you Perfect Locks, you regally are perfect!!!
This is the best hair I have Ever bought. I have Gotten so many compliments and have had no issues at all
I originally ordered a different color and once it arrived i changed my mind and decided to remain the color i currently have. I called to ask about how i can exchange them and they were very helpful. I received the new color right away and I LOVE LOVE LOVE the great quality of hair. I am very happy with my purchase and have referred co workers and family to their site.
My experience couldn’t have been better with this product. Color was spot-on as pictured, and each piece had tons of hair that is so soft and luxurious. This was my first, and definitely not last, order and my expectations were far exceeded. Thanks Perfect Locks!
I bought 25 more strands for my infusion installation, I currently have 7 bundles of the 25/strand Fusion I-tips installed. I have been wearing the PERFECT LOCKS Fusion I-tips since September, and I ABSOLUTELY love the hair! It blends so well with my natural hair it's like it is growing straight out of my scalp! People compliment how beautiful it is all the time. This by far is the best hair I have found for fusions, and I will continue to purchase. Thanks!
I have used several types of hair but i will have to say Perfect Locks is the best i've used, it looks so natural that most people think its my real hair.
Thank you so much for your review Tammy! Please send any pics we can post along with your review if you have them. . . And we would be so happy if you could write a Yelp and/or Google review for us! It's a great way to show people your work too! Perfect Locks Team ❤️
