You can catch dandruff if you use a comb or hairbrush of someone who has dandruff.
Dandruff is not a disease or a virus. It is not contagious, it cannot be transmitted from one person to another.
Dandruff is caused by fungus called Malassezia furfur (previously known as Pityrosporum ovale). This fungus is found naturally on the skin surface of both healthy people and those with dandruff. It feeds on the natural grease of the skin, from which it produces oleic acid. The oleic acid triggers increased turnover of skin cells, resulting in excessive flaking.
The difference between someone with dandruff and someone without it is that the fungus responsible for dandruff isn’t active in the person without dandruff. Obviously, you cannot get something you already have in your scalp. The flakes normally found on combs, hairbrushes, or pillows are just dead skin cells.
However, it is still not a hygienic practice to share combs and brushes.
