Experiencing dandruff on your hair or shoulders is not aesthetically pleasing. Dealing with the itchiness that comes with it is also quite bothersome. It is important to note that dandruff starts in the scalp, not just in the hair.
Dandruff is a form of dermatitis, or skin inflammation, with an estimated half of the population likely to experience it at some point in their lives, especially during adolescence.
Individuals have a natural variety of microorganisms on their scalp, known as the microbiome. In cases of dandruff, an imbalance in these microorganisms, known as dysbiosis, occurs, with certain types of yeast and bacteria being more prevalent in affected individuals.
Research by Amy McMichael and her colleagues highlighted the causes of dandruff, emphasizing that it is not a dry scalp as commonly believed, but rather an oily, flaky issue. Excessive oil provides a feeding ground for harmful bacteria and yeast, leading to increased flaking. Dandruff can affect areas of the body with sebum-producing glands.
Dandruff can affect people of all hair types, with some studies suggesting a higher prevalence in black individuals. Differences in hair care habits, such as frequency of shampooing, may contribute to this variation.
It is recommended to wash hair frequently to combat dandruff, focusing on the scalp to prevent further oil build-up. Using shampoos specifically formulated to fight dandruff can be beneficial, with stronger treatments available if needed. Conditioner is also recommended to lubricate the hair cuticle.
If experiencing persistent dandruff or other scalp issues, seeking medical advice is important to receive appropriate treatment and to rule out any underlying skin conditions.
McMichael emphasizes the importance of addressing hair and scalp concerns promptly for optimal results.
