I've tried to grow out my hair before, but every six months or so after a haircut the bottom one-two inches of my hair gets so much iron buildup from my hard water that it is dry, rusty-red, rough, and gets split ends very easily. My questions: Has anyone else here had this problem? and: Is there any way to get rid of the buildup without having two inches chopped off the bottom of my hair a couple times a year? One hairdresser said something about a chemical cleaner I could use, but I couldn't find it anywhere, and it doesn't sound very... um, healthy.
