Length Guide

Hair extension length guide showing examples from 10 inches to 24 inches on a model

Quick tip: Wavy and curly textures are measured when pulled straight, so they'll appear shorter when worn.

Choosing Your Length

  • Straight - Falls longest (measured as-is)
  • Wavy - Falls slightly shorter
  • Curly - Falls shortest (most volume)

Your hair may include 1-2" extra length since our Remy hair has natural ends. Trim to your perfect length or leave natural.

Customers praised these curly fusion U-tip extensions as "the best" with "amazing health" and natural texture. Shoppers noted excellent quality, longevity lasting 6-8 months, minimal tangling, and seamless blending with natural curls. Hair can be colored, straightened, or braided. One customer received curly instead of wavy but noted good quality. Some mentioned premium pricing and suggested shorter keratin tips.

  • This is the best, most natural curl you will

    This is the best, most natural curl you will ever find! Virgin cuticle, amazing health. Natural 1b color to maintain integrity, but So easy to color. Fusion is a skill well worth it! So light, inconspicuous, and low Maitnence!!! This hair is hard to find please carry it forever

  • Love this Hair!

    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.

  • Curly fusion u tip hair

    These extensions have been my absolute favorite out of all the ones I’ve tried and match my hair texture and color perfectly!

  • Best Utip fusions on the market hands down

    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!!

  • Absolutely love this oroduct

    Great quality, consistently meets all my expectations.

  • Fusion U tips

    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

  • By far the BEST curly u-tips on the market for beautiful big curly hair!

    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!
