Hair Transplantation (Planting) Process
The number of hairs on the body and their developmental stages
There are about 5 million hair follicles in the human skin, and about 100,000 of them are on the scalp. The growth phase of the hair on the scalp is about 2-5 years. In eyebrows and eyelashes, this phase is about 1-6 weeks. Hair grows about 0.3-0.4 mm per day.
It is considered normal to lose about 100-150 strands of hair in a day, and new hairs usually grow in place of the lost hair under normal conditions. Baldness is normally experienced not because of the loss of hair, but because the lost hair is not replaced by new ones.
Hair development passes through three different stages and with the last stage, shedding begins;
-
The anagen (growth) phase lasts approximately 3 years and hair growth occurs at a rate of 85-90%.
-
The catagen (regression) phase lasts about 2-3 weeks and hair growth occurs at a rate of 3-5%.
-
The telogen (resting) phase lasts for about 100 days and there is 10-15% hair growth. In people who experience intense hair loss, this phase can last quite a long time or much more parts of the hair are affected by this phase.
Unlike some mammalian species, the activity (cycle-cycle) of each hair follicle in humans acts independently of the other. For this reason, human hair does not shed completely in a synchronized (seasonal) manner as in some mammals. While some hairs fall out, others start to come out at the same time. As long as this balance is maintained, there will be no change in favor of hair loss.
Hair types
-
Vellus Hairs: They are soft, delicate and thin hairs that appear on the body from infancy to adolescence, except for eyebrows, hair and eyelashes.
-
Terminal Hairs: These are the hard and thick hairs that grow in places such as armpits, beard and groin on the body with the puberty period.
-
Intermediate Hairs: These have the characteristics of both vellus and terminal hairs and are the hairs that cause and/or accelerate hair loss depending on a number of factors.
Causes of hair loss
Factors such as genetic predisposition, hormonal problems, inadequate and unbalanced nutrition, weight loss, febrile systemic diseases, exposure to chemical substances, hair growth disorder, stress, air pollution, seasonal changes, skin diseases, surgical interventions, cancer treatment and side effects of some drugs. They either directly cause hair loss or accelerate the hair loss process on the skin.
Hair transplantation process
hair transplantation; It is the process of transporting skin and hair follicles (grafts) taken from body areas with strong hair follicles (such as the nape) to a region with sparse and/or no hair. Today, the most preferred hair transplantation methods are;
Follicular Unit Extraction (FUE)
It is the most preferred hair transplant method today. It is a viable method for both men and women. This method is preferred if a large area of hair transplantation is to be done. The procedure is usually performed in a single session and approximately 6,000 grafts can be collected in one session. Unlike other applications, there is no trace after the procedure. Side effects such as infection and bleeding are very low. With this method of hair transplantation, you can have healthy and permanent hair that will last a lifetime.
Direct Hair Implantation (DHI)
This hair transplant method is mostly; It is preferred if hair transplantation will be done in a narrow area. The procedure is done by pushing the grafts into the scalp with a pen, which has a hollow and spring mechanism.
Follicular Unit Transplantation (FUT)
Since it is an old technology, it is no longer preferred today. In this method, the hair is taken and transplanted as strips, not as grafts. The risk of bleeding is quite high and the success rate is lower than other methods. One of the most important problems is that it creates a horizontal line in the planting area.
