Increased dandruff must first be differentiated from the causes of increased dandruff before targeted treatment can be given. If the increase in dandruff is caused by certain inflammatory conditions of the scalp, such as folliculitis, sebaceous gland inflammation or head eczema, certain medications must be applied in a targeted manner to take treatment, such as anti-allergy drugs and antibacterial drugs. If the increase in dandruff is simply due to improper scalp care and incomplete scalp hygiene, scalp care can be carried out to promote a dry and clean scalp, and attention must also be paid to a light diet for increased dandruff.
