Kim Kardashian says that she only washes her hair twice a week. For different people, the question of how often should we wash our hair is varying.
When left unwashed, our hair became oily and smelly at times, how frequent should we wash it to keep it clean in a healthy way?
Your hair gets greasy for the same reason your face gets oily: glands in the skin produce an oily substance called sebum. Sebum is what moistens hair and keeps it from drying out.
The glands that produce sebum (called sebaceous glands) are located next to hair roots in the layer of skin called the dermis. Channels from the sebaceous glands lead to the hair follicle — that's how sebum gets out of the skin and onto your scalp.
The key thing about sebum is this: Each of us produces a different amount.
How much washing is right for you?
While the answer is different for everyone, there is one truth:
No one should need to wash his or her hair every day.
Washing too often, in fact, can do more harm than good, dermatologist and director of Boston Medical Center's hair clinic Lynne Goldberg told us.
"It's paradoxical, but people who wash their hair a lot to get rid of oil are drying out their scalp and producing more oil," Goldberg said.
