Finding the right balance between washdays and no-wash days is hard when it comes to hair. If you wash too much, you risk drying it out; if you take too long in-between washes, then your hair's 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.

Well, thanks to science we have now solved the hair equation.

There are multiple factors that come into play when it comes to learning how to properly treat your hair. Three things that should be considered when creating a washing regimen include: skin type, hair texture, and how you typically style it.

1. Skin Type
If your skin's in between oily and dry then you should be washing your hair only once or twice a week, according to Columbia University. If your skin's on the oily side, some people think you should wash it more often. You shouldn't. However, wash it everyday.

"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," explained Boston Medical Center's hair clinic Lynne Goldberg to Business Insider.

2. Hair Texture
According to Columbia University, different hair textures require different treatment. If your hair is on the coarse or curly side, then it doesn't get very oily since it's harder for oil to travel down your hair strands. These textures only command shampooing once a week. However, if your hair is fine and straight then you should shampoo twice a week or more.

3. How You 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. Don't shampoo it as much, dermatologist Paradi Mirmirani, tells Business Insider. Listen to what your hair is saying.

Yes, hair TALKS, ladies! You just have to learn how to communicate properly with you your locks. But once you have it down, it'll be a breeze.
