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.
