Listen to me again. Vitamin B6 can treat seborrheic dermatitis and promote hair growth. And don't wash your hair with that irritating thing. Bad for the scalp, it will aggravate white hair. Cod liver oil, cystine, vitamin B6. Three times a day. Most of them are related to living habits. Aipipi in Germany is very good at white hair. Basically and completely solve the white hair. Foreign friends rushed to buy. What is unbearable is that it is too expensive.
