How often should i wash my hair??

You only need to wash your hair when it is dirty - and that will depend on you. If your ends are dry, use a little conditioner on the ends only - with thinner hair you don't want the conditioner to sit on your scalp. Make sure you rinse all of the shampoo/conditioner out. If you want to increase your chances of thicker hair, you should brush your hair every night (to increase blood circulation to your follicles) - and use mousse when you style to give more body to your hair - only at the roots, though. If you use anything heavier or at the ends it will only make your hair look thinner. Good luck!
