Dandruff is a common scalp condition characterized by the flaking of dead skin cells from the scalp.
This is a type of yeast or fungus that naturally resides on the scalp of most adults. However, in some individuals, it can overgrow and lead to dandruff.
If your scalp is dry and lacks moisture, it can become flaky and prone to dandruff. Dry skin is often exacerbated by factors such as cold weather, low humidity, and using harsh shampoos that strip away natural oils from the scalp.
Infrequent or improper shampooing can lead to a buildup of oils, dead skin cells, and other scalp products, which can contribute to dandruff. Regular and thorough cleansing of the scalp can help prevent this buildup.
Certain skin conditions like psoriasis and eczema can affect the scalp and lead to dandruff-like symptoms.
Poor nutrition, especially a diet lacking in essential nutrients like zinc and B vitamins, can contribute to dandruff. Stress and lack of sleep can also weaken the immune system and potentially worsen dandruff.
Some hair care products, such as shampoos, conditioners, or styling products, may contain harsh chemicals that can irritate the scalp and contribute to dandruff in susceptible individuals.
Hormonal fluctuations, such as those that occur during puberty, pregnancy, or menopause, can affect the scalp's oil production and contribute to dandruff.
