Why people have hair?
Hair is one of the most important parts of our body. It protects our heads from the harmful UV rays of the sun and keeps our heads warm in cold weather. It also plays an important role in making us look good. Therefore, it is very important to take care of our hair.
The average person has around 100,000 hairs on their head. That's a lot of hair! And it's not just there for show. Your hair protects your scalp from the sun, keeps your head warm, and can even help absorb sweat.
But what exactly is hair? Essentially, it's a string of dead cells that are made up of a protein called keratin. Your hair follicles are responsible for producing new hair cells, and each strand of hair is made up of several different layers.
The outermost layer of your hair is called the cuticle. This layer helps to protect your hair from damage, and it also gives your hair its shine. beneath the cuticle is the cortex, which is responsible for your hair's strength and elasticity. Finally, the innermost layer of your hair is called the medulla. This layer isn't always present, and it isn't necessary for healthy hair (shop with hair).
So now that you know a little bit about what hair is made of, let's talk about how it grows. Your hair follicles are responsible for producing new hair cells, and they're located in the lower layer of your skin. Every follicle contains a tiny bit of blood vessels and nerves, which helps to keep your hair healthy.
Your hair goes through three different phases of growth: the anagen phase, the catagen phase, and the telogen phase. The anagen phase is the active growth phase of your hair, during which new hair cells are produced. This phase can last for several years, and it's responsible for making your hair grow to its full length.
The catagen phase is a transitional phase, during which your hair follicles begin to shrink. This phase only lasts for a couple of weeks, and it's followed by the telogen phase.
The telogen phase is the resting phase of your hair, during which your follicles are inactive. This phase can last for several months, and it's responsible for shedding old hair cells. After the telogen phase, your follicles will enter the anagen phase again and begin producing new hair cells.
