Dandruff is a skin condition affecting the scalp which results in dry white flakes and sometimes itchiness. It doesn’t result from poor hygiene, but genetic and environmental factors do play a role. The main cause being skin cells growing and shedding too fast. A fungus called ‘malassezia’ is the culprit behind it that causes inflammation of the scalp making it red and itchy and causing increased rate of shedding of cells. There are certain factors that exacerbate this cause such as:
- Dry skin: If your skin is dry due to certain conditions such as eczema or cold climates, it can lead to scalp dryness as well making it flaky and at times itchy.
- Irregular with brushing of hair: This can lead to build-up of dead skin cells and increases the chances of dandruff.
- Heat styling: Styling your hair with dry hot air can make the dandruff worse.
- Hair washing too often or too less: Either of these cases can lead to dandruff. If you shampoo too often, it can dry out the scalp and cause dandruff. Conversely, if you shampoo it too less, there is would be built up of oils in the scalp that causes dandruff.
- Stress: Surprised? Well yes, stress can exacerbate the dandruff and its best to reduce it.
- Seborrheic dermatitis: This is a skin condition characterized by irritated and oily skin in which extra skin cells are produced which sheds off forming dandruff.
- Lack of nutrients: Zinc, B-Vitamins and fats lack can increase the chances of dandruff.
- Hair products with chemicals: Certain chemicals in shampoos or leave in gels/sprays can irritate the skin of the scalp and lead to dandruff.
Dandruff is a condition which doesn’t need a healthcare professional to diagnose and is easily noticeable. Dryness of the scalp, itchiness and white flakes are classic signs of dandruff. An itchier scalp can be the first sign of dandruff. It is best to treat this condition at the earliest to avoid complications.
This condition can affect anybody regardless of age or gender. A frequently asked question that arises is whether dandruff leads to more hair loss? The answer is- yes. This is dandruff related hair loss which occurs as the hair grown on an irritated and flaky scalp is weak and damaged more prone to breakage. If itchiness is accompanied with dandruff, the friction can lead to more damage of the cuticles and hence leading to hair fall.
