Stem Cells

Stem Cells

Hairman works as a long lasting stem cell hair regeneration treatment that works to regenerate hair stem cells to prevent hair loss and regenerate new cells.

About Stem Cells…

The human body is made up of around 200 different kinds of specialised cells such as muscle cells, nerve cells, fat cells and skin cells. All specialised cells originate from stem cells. A stem cell is a cell that is not yet specialised.
Stem cells are found in the early embryo, the fetus, placenta, umbilical cord, and in many different tissues of the adult body. Stem cells are often divided into two groups: tissue specific stem cells (often referred to as adult stem cells) and pluripotent stem cells (including embryonic stem cells and induced pluripotent stem cells).

Stem Cells and Hair…

When hair dies, the layer of fat in the scalp that comprises most of the skin’s thickness shrinks. When hair growth begins, the fat layer expands in a process called adipogenesis. After many studies researchers have found that a type of stem cell concerned with creation of new fat cells was required for hair regeneration in mice. They also found these cells produce molecules called PDGF (platelet derived growth factors), which are necessary to produce hair growth in humans.

The regeneration process…

In order for a new round of hair growth to begin, stem cells in the hair follicle must be given a signal to divide. In response to this signal, the hair follicle regenerates first by growing downward through the skin’s middle layer, the dermis, and then generateing the specialized cells that form the hair. After a period during which the hair grows, stem cells stop dividing and the hair follicle gradually retracts again. There is then a period of rest and the cycle starts again.
