I've been trying everything to get my hair into good condition: I use an "anti-breakage" shampoo and conditioner, dry it gently, use a leave-in moisturising product, brush it carefully with a Tangle Teezer and tease out any remaining knots before before using a normal brush to style it, but still I get broken hairs and my hair goes frizzy if it's remotely damp outside.
I see people with beautiful shiny hair with no obvious breakage or split ends. How do they do it, and what am I doing wrong?!
My hair is chin-length, not dyed or bleached, doesn't feel particularly damaged and the hairdresser always says the condition is fine. I'm blonde and the individual hairs are quite fine, I think.
