It's normal to grow gray hair at the age of 30
Not only is there no problem with getting whiter hair in your 30s, it is actually normal. “Belly hair usually occurs between your 30s and 40s, depending on your bloodline,” Dr. Taylor said. She added that studies show that whether white or Asian people, they usually start to see gray hair in their 30s. Black people start to have gray hair at the age of about 40. However, if you have white hair in your 20s, it is a sign of early aging. Basically, as you age, melanocytes start to lose the ability to make your hair look yellow, brown, or black. In addition to that, you will also lose some melanocytes. Some people with premature aging will experience diffuse graying after the age of 30, which means that the whole hair will turn white.
In addition to the natural aging process, there are some other factors that can also cause hair to turn white. Dr. Taylor pointed out that excessive drinking and smoking are big problems. Studies have shown that both habits can cause “oxidative stress”, which means you have too many unstable molecules called free radicals in your body, and without enough antioxidants to neutralize them, it can lead to premature hair whitening. Dr Taylor also added that genetics and certain chronic diseases, including autoimmune diseases such as leukoplakia, are also associated with premature gray hair.
