Which Hair Extension Weight Looks Most Natural?
The most natural weight is the one that matches your natural hair density.
Generally:
- Fine hair → 100g–120g
- Fine to medium hair → 120g
- Medium hair → 120g–150g
- Thick hair → 150g+
Choosing a weight that’s too heavy can sometimes make blending more difficult.
Common Mistakes When Choosing Hair Extension Weight
Choosing Based on Length Alone
Longer extensions usually need more weight to maintain fullness.
Assuming More Hair Is Always Better
Heavier extensions aren’t automatically the best choice. The goal is a seamless blend with your natural hair.
Ignoring Hair Density
Hair thickness matters just as much as extension weight when creating a natural look.
