Ginger applied to the scalp in general produces a certain auxiliary therapeutic effect on hair loss. Especially for baldness, the use of ginger, especially ginger slices, applied to the skin area of baldness can stimulate the blood circulation of the skin and increase the local capillary expansion, which is conducive to the formation of hair follicles and eventually the formation of hair growth. However, for other types of hair loss, ginger applied to the scalp also has no significant effect on hair growth, such as seborrheic alopecia, the effect is very limited. So for ginger on the scalp, its main effect is to stimulate the skin surface and enhance blood circulation. In addition, to a certain extent, the formation of hair follicles, but after all, it is a limited therapeutic effect.
