I started using them around 5 years ago when after several home hair dyes had ruined my hair. Since then my hair is now mostly natural grey with some blonde highlights. I use the shampoo and conditioner every other day and the no 3 once a week. More recently my hair seems to be very dry and is damaged at the ends of my fringe. This has happened since I last had more highlights in my hair. I cannot get it any better despite it being over a month later, ends trimmed off and straigheners used at lowest heat for a few seconds.
Do I need to change products? If so, what to? My hair is shoulder length, fine, quite flyaway with a bit of a wave and mostly grey (apart from added blonde bits)
