Our hair has a more complex structure than the visible surface. When you look in the mirror, you can see a different operation in the hair follicles, even though it looks like a thin or thick, normal or different colors of long or short hair. So what is the effect of hair on the appearance of men and women? Hair also plays a role in the formation of gender and identity, and even in our emotional encryption. Now we want to share a series of information that we didn't know about hair before and that we guessed you didn't.
While our hair follicles are still in the belly of our mothers, almost all of them have been formed in the 22nd week of the fetus. At this stage of our life, approximately 5 million hair follicles are formed in our body. 1 million of them are only in our skull. This rate gradually decreases after the baby is born and the age begins to progress and the hair follicle begins to dilute. It is argued that the reason for this is that the scalp that grows over time causes the loss of follicle.
Structure of hair follicles
Hair follicles consist of the follicles on the scalp and the follicles just below it. The hair root is connected to the epidermis, which extends into the dermis, just like a tunnel. All of these are composed of several layers. At the base of the follicles are capillaries and papillae containing small blood vessels that feed the cells. The part of the papillae that provides the feeding of the hair and the part called the bulb constitutes the lowest part. The cells in these areas have the vitality to divide and live more clearly and faster than the cells in any part of our body.
There are inner and outer sheaths surrounding the hair follicle. These structures are useful in the formation and protection of the growing hair. The inner sheath follows the hair shaft and is surrounded by oil gauze. The outer sheath surrounded the hair along the entire length of the hair. Thanks to these sheaths, distinct properties such as the dryness of the hair or the fact that it has an oily structure. This oily form is called hair sebum. Sebum is very important for the vital properties of hair. Hair follicles that produce a lot of sebum in adolescence, as they get older in time to produce less, and thus cause the hair to dry faster.
Hair and keratin
The hair is composed of a fixed protein called keratin and consists of 3 layers on the hair. Actually, these proteins are dead cells, so we can say that hair is not a living structure. The first layer of keratin is called medulla. Medula is the color of the hair and do not change. The second layer of the cortex makes up the majority of the hair shaft and makes the hair type, thin or thick. The outermost layer is called the cuticle and determines the color of the hair.
