What exactly are a hair follicle and PRP treatment?

The hair follicle is a pouch-like structure located in the hypodermis (deeper layer of the skin). It is located inside the root of the capillary wire. Each hair follicle can produce and grow hair strands, with 90% of the follicles producing one hair at a time and 10% producing two or more strands at the same time.

There is a very complex cutaneous attachment and has different cell types and multiple functions. Some of these functions are self-renewal capacity, the potential for immortality, and rapid growth. It also produces sebaceous glands to expel fat for the lubrication of the skin.

Throughout the human body, it is estimated that there are about five million hair follicles, they are all over the surface of the body, except on the palms of the hands and soles of the feet.

There are two types of hair produced in the follicles: the hair shaft and the veil. As for the biological cycle and the anatomical aspect, both are very similar. What sets them apart is the size. The terminal is thick, long, pigmented, with piloerector muscle and medulla, with a diameter of 0.06mm or more. The fleece is small in size, less than 2 cm in length, thin, soft, without marrow, poorly pigmented, without erector muscle most of the time, and with a diameter of approximately 0,03 mm. The fleece type can be transformed into a terminal, as occurs in men’s beards after puberty. Terminal transformation into fleece occurs in the evolution of androgenetic alopecia.

The hair strands grow 0.33 mm per day, that is, about 1 cm per month. A person with the growth phase (anagen) of 2 years, will have hair 24 cm in length. Another with 5 years of growth will be 60 cm in length.
The normal daily fall of hair is directly related to the total number of hair, and also to the duration of the growth phase. Usually, a person has on average 100,000 hairs and a growth phase of 3 years, that is, this person exchanges about 100,000 hairs every 1000 days, having a loss of 100 hairs per day. If the individual has more than 100,000 yarns, with the same growth phase time, he will have a greater daily loss.

What is PRP?
PRP is a treatment in which the patient’s blood is collected and centrifuged to separate the platelet-rich fraction. After this process, this fraction is applied to the scalp and because it contains natural growth factors, it assists in capillary growth.
