Weft Pack Guide: How Much Hair Do I Need?

We recommend 45g-100g to add thickness, or 150g-200g for a full head application to achieve both thickness and length.

These quantities are a starting guide. The amount needed depends on your natural hair’s density, current length and desired finish. Your extensionist should confirm the quantity before ordering, particularly for a blunt haircut or a significant increase in length.

Shades: Available in 35+ bespoke tones

Application: No glue, no heat & no damage to the natural hair.

Best for: Colour melts, balayage blending, seamless colour transitions and adding ultra thickness.
