For those who have been struggling with an itchy scalp and dandruff, you’re not alone. In fact, according to the American Academy of Dermatology, dandruff affects up to 50% of the population. While dandruff is not a serious medical condition, it can be embarrassing and uncomfortable. The good news is that there are a number of effective treatments available.
What Causes Dandruff?
Dandruff is caused by a fungus called Malassezia. This fungus lives on the scalp of most people, but in some people, it can overgrow and cause dandruff. Malassezia feeds on the oils on the scalp, and as it does, it produces a substance called oleic acid. Oleic acid can irritate the scalp and cause it to become itchy and flaky.
