Note: Not all alopecia patients are suitable for ginger treatment. Ginger contains volatile oil and gingerol, which can stimulate scalp blood vessels, strengthen local blood circulation and promote hair growth. It is worth noting that the irritation and excessive stimulation of ginger will cause adverse reactions such as erythema and blisters on the scalp. Stimulating the scalp of a "milk bald" baby with ginger is more likely to lead to the above reaction. However, seborrheic alopecia is mostly considered to be caused by damp-heat stagnation in the liver and gallbladder and fumigation of the skin on the head and face. Fever should be cold, and ginger is warm, which is not suitable for treating this kind of alopecia.
