Looking into the hair follicles in microscopic manner does reveal that they are regarded to be an interesting miniscule body organ, which is way apart from the other organs that are tissue based.
Hair Cycle-Different hair growth stages
1. Anagen phase :
It is regarded to be an active development phase in follicles. The scalp cells do stay in this phase for about 2-6 years.
The unknown chemical induced signals tends to imply the follicle stem cells in growing as permanent portion of follicles-Derma Papilla that gives signals to hair matrix cells, such that the cells develop wildly and become pigmented, hence attenuating new hair shafts.
90% of the hair cells are said to be in this particular stage at any point of time.
2. Exogen phase :
This is considered to be the shedding hair growth phase. Here, new hair shafts pushes the older and the dead ones out from the surface of the skin.
3. Anagen finished:
The new hair shafts, in this phase extends beyond the skin surface and keeps developing fully to maturity.
4. Catagen :
In this phase, a brief transition takes place at the end of the anagen phase 2/3 of the lower follicles shrive up and get destroyed in this phase, while Dermal Papilla remains attached to regressing follicles.
5. Telogen phase :
This is rather a resting or pause phase for the developing hair follicles. In this particular phase, the withering follicles take adequate rests, waiting for the chemical signals to prompt it to being fresh, once again.
What is Hair Transplantation?
Hair transplantation is considered to be a surgical procedure, which moves the individual hair follicles from the body part, known as ‘donor site’ to the bald or a balding portion of the body is called the ‘recipient site’. Primarily, it is used towards treating male pattern baldness.
This particular modern and minimal invasive procedure calls grafts comprising hair follicles, which are resistant genetically to balding and are transplanted to bald scalp. Moreover, it can be used for restoring beard hair, eyebrows, eyelashes, public hair, chest hair and for filling up scars that are caused by surgery like previous hair transplants and face lifts or due to any type of accident.
Hair transplantation tends to different from skin grafting. The graft compromises of almost every dermis and epidermis that surrounds hair follicles. Numerous tiny grafts are then transplanted, instead of a single skin strip.
As hair grows naturally in groups of 1-4, today’s advanced techniques transplant and harvest such naturally occurring hair ‘follicular units’ in the natural groupings. Therefore, modern hair transplantation techniques can indeed obtain a natural appearance and done by mimicking natural hair.
