Stopped using foil on highlights after a client in Austin asked me why her hair felt so dry
I used to wrap every highlight foiled section in foil and call it a day, which I did for probably 4 years. About 6 months ago a client sat down and mentioned her hair felt rough and straw-like at the roots after her previous appointments, and I started thinking about heat and how foil traps it. So I switched to using a clear plastic cap for the top sections and only foiling the mid lengths, and the difference in how the hair feels after rinsing is night and day. I also started checking the developer volume, because I was using 30 on everyone out of habit and now I mix 20 for most clients unless they need serious lift. My color results are actually more even now, and I get way fewer complaints about dryness between visits. It took maybe 3 appointments to feel confident with the change, and honestly my neck and back thank me too because I'm not bent over foiling for an hour straight. Has anyone else dropped foil for plastic caps on certain textures, or do you find foil still gives you better control?
I switched to plastic caps for the top sections about a year ago and it made a huge difference on fine hair especially. Foil still wins for me on the mid lengths and ends though, since I can see the lift better and control the placement. The developer thing is real too, I was guilty of reaching for 30 out of habit and dropping to 20 for most clients cut way down on the dryness complaints. Takes a minute to trust the process but the hair just feels healthier after rinsing, no question.
