Hehe, don't worry if you buy it right. Ginger can really promote hair growth and treat alopecia, but remember that conditioner can only be applied to hair, and never applied to scalp hair roots, otherwise there will be dandruff. In addition to using ginger conditioner, you can also massage the hair loss area with ginger slices, which will be effective every day. In addition, eating more black sesame seeds, yam and other foods can also accelerate hair growth. A friend of mine said that eating these foods really grows hair.
