I’ve tried Redken, Olaplex, Davines (from my hairdressers), Philip Kingsley and my hair which is straight is still like straw. I don’t dye it and am washing, conditioning and blow drying every 3 days and use a heat protectant, a leave in conditioner and olaplex oil. I’m in my 60s, take HRT, Vitamin D, B complex and zinc, Im not anaemic but just have crap hair. It’s always been thin, dry and fine but as I get older it’s just getting even dryer. I’ve only got random grey hairs which have a life of their own. Any recommendations for a shampoo and conditioner that might help get some more moisture into it?
