    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.

    Straight Fusion U-Tip

    I personally loved it! I would definitely buy it again the only thing that people might not like about it is that it is not naturally straight. It has a wave/ curl to it which I already knew due to reviews so it match perfectly with my hair! I loved it!
