When I was 13 years old my dandruff was so bad my Mom told me to put baby oil on my scalp at night, thinking it might help. I took my showers at night at the time so the next morning I didn't have enough time to wash the baby oil out. I was a metalhead with long hair and all day in school my hair was not only incredibly oily (even my English teacher made a comment!), but the dandruff and itchiness was still rampant. It wasn't a fun day. 15 years later, I finally figured out how to get rid of dandruff. You might cringe at first, but hear me out. I haven't washed my hair in 6 months. You might not believe me, but it's true. Before I get into the process (it's not simply "don't wash your hair"), let's talk about what causes dandruff. According to this BBC News Health article, dandruff and itchy scalp are caused by overactive Malassezia fungus. This fungus is naturally found on human skin, but if it's overactive it causes a fast turnover of skin cells. In other words, Malassezia produces flakes faster in dandruff sufferers than in people without dandruff. If you have oily hair (like me) then you're more susceptible to dandruff, since Malassezia feeds on sebum, the oily matter produced by the sebaceous glands in our skin. You'd think not washing your hair would just make your hair even more oily, right? In the past if I didn't wash my hair for one day I'd have gross oily hair until I washed it again. Then in February of this year my friend Rachel randomly mentioned that washing your hair every day isn't necessary and actually makes it look worse. I immediately stopped washing my hair. I decided to test it out for 30 days. That means the last time I can remember washing my hair is sometime in March! The interesting thing is after a few days my scalp seemingly stopped producing so much oil. I don't know the science behind it, and I haven't been able to find conclusive studies about it, I just know it works. Some people use baking soda and vinegar. Or lemon juice. These products don't strip your hair of its oils. But I don't use any product of any kind in my hair.
