Rubbing the scalp with ginger, to a certain extent, can also play a role in hair growth, especially for baldness, if you use ginger slices to rub the head locally, can to a certain extent promote local hair follicle generation, as well as hair growth. As ginger stimulates the scalp, it may stimulate the local epidermal capillaries, thus accelerating the local blood circulation, which has a certain role in promoting hair growth and follicle generation. But for other types of hair loss, the effect is generally not obvious, this usage in the clinical treatment effect, after all, is very limited. So if the patient has hair loss, also need to carry out drug treatment. If it is baldness you can use Minoxidil tincture topically, and you also need to take oral medication, such as baldness pills.
