Found out I was cutting my foils too wide after a client's hair snapped
I've been doing highlights for 4 years and always cut my foil sheets into big 6 inch squares because I thought it gave me more room to work. Last Tuesday a client with fine hair came in and two inches of her hair just broke off when I pulled the foil out, and I felt awful. My coworker at the salon in Portland watched me and said the foil was too heavy and wide, so the hair couldn't slide out right. Switched to 4 inch strips with a lighter fold and her next visit went fine, no breakage at all. Anyone else learn a basic thing way later than they want to admit?
