How many foils for a full head of highlights?

A full head of highlights on medium-length hair typically requires 50-70 foils depending on the thickness of sections and the density of coverage desired. Fine highlights use more foils than chunky highlights.

What foil width should I use?

Standard foil widths are 10cm (4") or 12cm (5"). Wider foils are easier for beginners and suit chunky highlights. Narrower foils give more precision for fine weaving and babylights.

How long does foil application take?

An experienced stylist typically applies one foil every 1.5-2.5 minutes. A full head of 60 foils takes roughly 90-150 minutes for foil placement alone, plus mixing and processing time.

How do I calculate foil stock for the salon?

Track your average foils per service, multiply by weekly services, and keep at least 2 weeks of stock. Most professional foil boxes contain 500 or 1000 pre-cut sheets.
