Looking for advice - had a full head of thick hair but recently loosing a lot on combing and it feels thin at the ends. I’m 56 with coloured hair but only have roots done and wash every other day / I use redken all soft shampoo and conditioner and use as hoc heat protecting spray - I used to straighten to but have ditched this. Any ideas on what o could use as a treatment to thicken. I’m healthy with my diet and take a good multi vitamin. Help !
