The main effect of ginger shampoo is to stop itching, anti-dandruff and clean. First, dandruff mainly comes from the colonization of furfur spores, ginger juice itself has a certain inhibitory effect on bacteria and fungi. So it can play an anti-dandruff and anti-itch role. Secondly, ginger contains a lot of volatile aromatic substances, including 6-gingerol, which has a certain role in promoting the blood circulation of the scalp. But it is worth noting that in the preparation of ginger liquid, the content of ginger liquid is elevated, the stability of the shampoo, pH and foam height will change. Ginger liquid added more instead of affecting the performance of the shampoo, so in order to achieve a balance, the raw material concentration of ginger liquid is also not easy to be too high, generally between 3%-5%. Third, in addition, ginger shampoo also has its own cleaning effect.
