Fusion I tips 613

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.

Hey Beautiful, We want to thank you for taking some time to provide us with great feedback. We strive to keep our customers happy! We are glad to hear that you are enjoying our product!

Straight fusion I tip

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 ❤️

Very thin and not straight

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.

Best hair ever!!

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!!!

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.

Best quality I have ever used!

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!

Fusion

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!
