For those of you who were interested in the Alterna anti ageing butter. I've been using it for a few weeks and it has improved the texture of my hair. As it protects against the heat my hair doesn't feel as dry. I've only been using about a 10p worth of product daily as a little goes a long way. As for the anti ageing aspect I'm still unsure but overall good results.
Beauty flash have it for £24.50 and it was about £10 more at the hairdressers. I only use a tiny amount, about 10p worth of product. It spreads pretty easily on my shoulder length hair and it doesn't take as long to dry. It protects against heat too.
