The Science behind Hair

Updated: May 14, 2020

Our hair proves to be one of the features that allow us to be unique. This is true even without hair. Everyone is unique. Many people occasionally go to the salon to trim or style their hair. Sure, it may be a little scary seeing a potentially psychotic stranger approach you with scissors and attempt to trim your hair, but still! It's fun! After a couple months, your hair grows back. But, how does this happen? How does your hair grow back?

Firstly, have you ever wondered what your scalp looks like? No, it doesn't look like a peeled potato. If you were to look a bald scalp very closely, you would notice little tiny holes in your scalp. I assure you, it isn't the horror movie scene you think it is. These little holes in your scalp are called follicles. These follicles may be small but they are part of a bigger picture. These follicles are like the structure of the hair. It is crazy to imagine that each tiny follicle is made up of different parts itself. Some of these parts include the papilla, the bulb, and the inner and outer sheaths.

Every follicle can grow one thin strand of hair. Now, there are around 5 million follicles on a person's body! Imagine 5 million strands of hair! There is a root at the bottom of each follicle. The hair you see grows out of the cells in the roots.

The hair keeps on growing and growing and growing and growing (I think you get it) until it pushes out of the skin. As the hair grows out of the skin, it passes by some oil glands that give it a certain consistency, such as being smooth. But, beware! You don't want your hair to be too oily! Seriously, know when your hair stinks. Too much grease from the oil glands is not good for your hygiene!

Though hair might be dead, we certainly aren't. It matters to maintain proper hygiene. After all, you don't want to be a walking, talking, stinky garbage bag! So, stay clean and healthy everyone! Especially in times like these!

Stay safe, healthy, and wash your hair!
