Many people have serious problems when coping with hair loss, that is why scientists go on studying the problem and looking for the best and most effective solutions and hair loss treatments. Recently, the findings of a new study carried out by the specialists at Yale University were published revealing a new tendency in hair loss treatment efforts. It is reported that the study has shown that there are certain molecular signals coming from stem cells within the fatty layer of the skin, and it is supposed that this signals can help in triggering hair grows and playing a role for a new effective natural treatment for hair loss.

All men who suffer from male pattern baldness have plenty of stem cells deep in the roots of their hair, and the problem is that these stem cells lose the ability to cause hair regeneration. That is why hair loss occurs, the scientists are convinced. During the experiments, the Yale scientists tried to identify these kind of stem cells and spur hair growth in mice.It was known that it is necessary to send some signals to the stem cells in order to “charge” them for growing hair, and the scientists worked to find out what can be the source of such signals.

Valerie Horsley, one of the study group liders and assistant professor of molecular, cellular and developmental biology, says: “If we can get these fat cells in the skin to talk to the dormant stem cells at the base of hair follicles, we might be able to get hair to grow again.” During the experiments the specialists found out that when hair dies, the fat layer of scalp where the most of hair roots existed shrinks. And when the process of hair re-growth is activated, the layer of fat under the skin starts expanding again.

It was also found out that stem cells linked to hair loss produce special chemical compounds called PDGF (platelet derived growth factors), which play an important role in hair re-growth. Horsley underlines that further researches are required to figure out more connections between stem cells and their signals and effective hair re-growth. It is possible to read a full report about this interesting study in the September 2 issue of the journal Cell.
