Dandruff is a major skin problem that affects most people of all ages. It is a condition in which dead cells on the scalp dry out and fall off in small white flakes. Dandruff is not just a cosmetic problem, it can also cause chronic hair loss, acne, and severe itching on the scalp. Here are the 5 main scientific reasons behind dandruff on the scalp:
Overgrowth of the fungus ‘Malassezia’: Malassezia is a type of fungus that is naturally found on the scalp of all of us. It lives by feeding on sebum, the natural oil of the scalp. But in some people, this fungus multiplies excessively and this stimulates the scalp and destroys more cells faster. These dead cells become dandruff.
Oily Scalp: When the sebaceous glands in the head produce more oil than necessary, the scalp always becomes oily. This oiliness creates a suitable environment for the above-mentioned fungus to grow. In addition, dust and dirt in the air stick to this oiliness and make dandruff hard.
Dry Scalp: Dandruff is also common in people with dry skin. Especially in the winter or when you stay in AC rooms for a long time, the scalp becomes dry and the dandruff flakes off in small white flakes.
Not washing your hair properly and getting dirty: Dust and sweat accumulate on the scalp of people who go out and work every day. If you do not clean your hair with a mild shampoo at least twice a week, this dirt will combine with the cells and turn into dandruff. Similarly, excessive use of chemical-filled hair gels and sprays can also increase dandruff.
Mental stress and poor diet: Severe stress can affect the body’s immune system and reduce its ability to fight fungal infections on the scalp. Also, eating too many sweet and oily foods can cause hormonal changes in the body and increase oiliness on the scalp, leading to dandruff.
