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.

Customer Reviews

Verified photos and videos from customers wearing this hair.

Customers praised these tape-in extensions as "totally invisible" with excellent quality. Shoppers noted they're "great on fine hair" and the "strongest without damaging." Stylists were impressed enough to switch brands. However, some found coverage minimal for the price, and one customer reported color treatment didn't take.

Didn't take color

So I got the hair and I wanted it colored. I attempted to color it myself and nothing took. Called customer service and they said there was nothing they can do since I colored them.

Dear Kathleen, thank you for sharing your experience with us. We’re sorry to hear about the challenges you faced with coloring the hair. Our extensions are carefully processed, which can sometimes impact how they take color, but we’re here to guide you through best practices for any future customizations. Please don’t hesitate to reach out for recommendations-we’d love to assist you in making the most of your purchase! Perfect Locks Team ❤️

Stylist love the hair

I was at first worried due to using the same brand for years now and I'll definitely be switching over to these Best hair I have ever had installed. My hairdresser was so impressed with the quality she is now ordering from Perfect Locks! I had my hair installed for a cruise to the Bahamas and these were a lifesaver!

Good for fine hair

I've been buying only perfect locks for years now. They are great on fine hair!

Dear Rachel, thank you for being such a loyal customer over the years! It’s wonderful to hear that our extensions work so well for fine hair-it’s feedback like yours that reminds us why we do what we do. We can’t wait to keep serving you with products you love. Perfect Locks Team ❤️

Best tape ins

So far this tape in has been the strongest without damaging my hair.

R
Roberta (Boardman, Oregon, United States)

Perfect locks is quite at first glance. Received my hair and was very surprised at how little was in the package for the price. The quality was great and the color was perfect. But it literally didn't cover anything. I will play with it more and hope that my assessment changes.
