I'm mobile and did a new lady yesterday for capped highlights. She had short hair with maybe 2 inches of root and about 1/2 inch of bleached ends. Pulled through and applied on roots for 25 mins (bleach and 30vol) took through to the ends for the last 5 mins just to freshen them up. When I was cutting I noticed the ends were a bit fragile (not to the point I was really worried), but she was adamant she only wanted the tiniest bit cut off, everywhere else was fine. She has text me today to say her hair is breaking off! I'm going to see her again tomorrow and explained it could be the overlap and maybe just having a bit more cut off would help. Anyone got any advice of what else to say/do?
