Keratin is a protein that makes up hair. The strand is composed of three layers: the inner medulla and cortex layers, as well as an outer layer called the cuticle. The hair root can be found below the surface of the scalp or skin and is contained within the follicle. The dermal papilla is located at the base of the hair follicle and is crucial for hair growth. The dermal papilla is where the hair gets its nourishment. It also contains the receptors to androgens. Androgens regulate the growth of hair on the scalp. This hormone is responsible for most hair loss issues in both men and women.
Let's start with how hair grows to understand hair loss. The hair follicles are where hair growth begins. Old cells are being pushed out at a rate of about half an inch per month as new hair is created by the follicles. You can see a string of dead cells in the hair. In its three-phase life cycle, the hair follicle experiences three phases. These phases are the anagen, catagen and telogen phases. They represent growth, transition and resting phases.
About 90% of hairs are currently in the growth phase, while 10% are still in the resting phase. During the telogen phase, the hair follicle is dormant for up to four months. The resting phase ends and the hair cycle resumes with the growth phase. The old hair strand is pulled up and shed in order to make way for a new one.
As we age, however, our growth rate slows down. This is why some hair loss naturally occurs as we age. The body has a fixed number of hair follicles. There are approximately 100,000 follicles on the scalp. Follicles cannot be added to during life. If the rate at which follicles shed exceeds that of regrowth, there is noticeable loss Platelet Rich Plasma in Washington DC
Temporary hair loss can be caused by many factors. Most commonly, temporary hair loss is caused by hormonal imbalance, emotional stress, medications, irritation, or damage to the hair follicles. After the problem is resolved, hair will grow normally again.
While gradual thinning is normal with ageing, pattern or androgenetic hair loss is extremely common and affects both men as well as women. This is the most common form of balding among men. This is a genetically-determined condition where the hair follicle shrinks over a period of time. It results in finer and shorter hair. The follicle might stop growing new hair eventually. The follicle is still alive and can be used to regrow hair.
If you're comfortable with your hair, then it is not necessary to treat hair loss. It is better to treat hair loss early. There are hair loss remedies that can be used to control excessive hair loss and help you regrow your hair.
