A healthy scalp starts with clean hair. Hair products make the hair dirty. Anti Frizz, hair gel, hair mousse, serum and hairsprays cause a buildup that clogs the hair follicles. Even a dirty hairbrush clogs follicles. If you wear a wig wash your hair after using it and clean hairbrushes regularly.The only way to have clean healthy hair is by washing the hair two to three times weekly. Washing the hair with a good shampoo prevents clogging of the pores and inflammation that comes from dirty clogged hair follicles. Use a Paraben free shampoo. Change the pillow cases on the bed daily. Always use a clean towel after washing your hair. Having clean hair will prevent the hair from becoming thinner. Regular brushing will increase hair growth. A good hairbrush works wonders. Invest in one. Choose a Mason Pearson hair brush. It will last forever.
