stylist notes
How many grams does a full head of extensions need?
A simple grams chart by length and density, so you order once and never run short mid-install.
Running short in the middle of an install is the most expensive mistake in extensions. Use these starting points and adjust in consultation.
For length
- 16–18 in: 100–125 g for fine hair, 125–150 g for medium.
- 20–22 in: 125–150 g for fine hair, 150–200 g for medium.
- 24 in: 175–225 g, depending on how full she wants the ends.
For volume only
If the client keeps her length and only wants more body, 50–75 g is usually enough, placed through the crown and the sides.
Thick hair
Add 25–50 g to each figure above, or switch to wefts so you can stack rows.
Order a little extra
Keep one spare pack per shade you use most. Unopened packs can be exchanged within 30 days.
