This Is How Often You Should Wash Your Hair, According To Science

Finding the right balance between washdays and no-wash days is hard when it comes to hair.

If you wash your hair too much, you risk drying it out. If you let it go too long in-between washes, then your hair is likely to become an oily mess.

Oh, and let's not forget to account for the fact that everyone's hair is different, so the answer is almost never black and white.

How often should you wash your hair?

Thanks to science, we have found the solution to this clean vs. dirty hair equation.

There are multiple factors that come into play when it comes to learning how to properly treat your hair.

There are 3 things you should take into considered when determining how often you really need to wash your hair:

1. Your skin type

If your skin run in-between oily and dry, then you should be washing your hair only once or twice a week.

If your skin runs more on the oily side, however, you should probably wash it more often.

You shouldn't. However, wash it everyday.

"It's paradoxical," says Lynne Goldberg, dermatologist and director of Boston Medical Center's hair clinic, "but people who wash their hair a lot to get rid of oil are drying out their scalp and producing more oil."

2. Your hair texture

According to Columbia University's health resource service Go As Alice!, different hair textures require different treatment.

If your hair is on the coarse or curly side, then it doesn't get particularly oily since it's more difficult for oil to travel down the strands of your hair. Hair with this kind of textures only demands shampooing once a week.

However, if your hair is fine and straight, you should shampoo it somewhere around twice a week or more.

3. How you typically style It

No matter what your hair is like, the rules drastically differ depending on how you style it.

If your hair is processed or damaged, then go easy on it, and don't shampoo it as frequently. Listen to what your hair is saying.

Yes, your hair can talk to you, ladies! You just have to learn how to communicate properly with you your locks via their non-verbal forms of communication.

But once you have it down, the rest will be a breeze.
