there's another story in the press about allergic reactions to home hair dye. i dye mine roughly every 5 weeks, but am now a bit worried. don't normally do a patch test but will make sure i do from now on. but have a few questions...
- is a patch test for a home dye suficient to check for any reaction?
- is a reaction more likely with darker colours?
- anyone know of any ppd free home dyes? they seem more widely available everywhere else apart from the uk!
