Hi Vanessea, I think you've hit the nail on the head. People of a sensitive nature usually are also sensitive in other ways too......such as allergies and intollerances with products and food and chemicals....etc. The best way to tackle all this is to use products that dont have all the harming chemicals and additives in them......such as using 'Faith In Nature' Rosemary shampoo and the conditioner. You will only find these in a health shop. Rosemary helps regrowth of hair.
Also using a dark colour on the hair has a common allergic reaction.
Relaxation methods will be an added bonus to reduce or elliminate stress......perhaps reviewing what else is going on in and around your life.
By sorting out these issues from the outside and also from the inside.....things then usually resolve themselves eventually.
