I have just bought a new hairbrush - a Mark Hill big round brush - for my shoulder length hair. Staggeringly, I have managed (for the first time in my life) to blow-dry my hair with salon blow dry results, without even trying. It is all smooth, full and glossy and is most definitely down to the brush. The packaging said it was improved ceramic technology - wish I'd kept the box now. My life feels transformed - just thought I'd share.
