Take more showers but use colder water. The hot water might dry out your scalp. Use special shampoo such as head and shoulders. And maybe use a coconut oil hair mask once or twice a week. Happy late birthday love
But you don't want to dry your hair out by too much washing. Try to keep it at about 3 to 4 times a week to was your hair. Four or more times can dry your scalp and hair even more and bring on more dandruff.
Also, I have tried using a green mouthwash as a rinse for my hair for dandruff. It worked for me.
