As people age, their scalp hair tends to get thinner. Age is a natural, slow-paced cause of gradual hair loss in both men and women. There are, however, other causes of hair loss for both sexes - some beggining as early as puberty.
Normal Hair Growth Cycle
There are three phases of hair growth: Anagen, Catagen and Telogen. Anagen is the growth stage and can last up to 5 years, during which the cells divide to produce new hair fibres, nourished by hair follicles buried in the skin. This phase os followed by the Catagen phase - the transitional phase. Here, the hair follicle shrinks to 1/6 of its original length pushing the hair upward. Finally, during the Telogen phase, the follicle rests for 1-4 months preserving the hair in its place. At some point the hair base will break free and the hair will be shed, giving way for a new hair shaft to emerge and thus restarting the cycle with the Anagen phase once again.
Up and coming treatments extract platelets from patient's own blood and combine these with active solutions to stimule hair follicule and "switch" them into anagen phase.
Hormonal Factors as Causes of Hair Loss
This common cause of hair loss affects a large proportion of general population, causing male-pattern baldness. In people affected by this condition, certain hormones can trigger a particular pattern of permanent hair loss. In particular, a hormone called dihydrotestosterone, also referred to as DHT, can negatively affect hair growth on the head, while promoting facial hair growth. DHT causes hair follicles to shrink, eventually shortening the anagen phase and thus preventing the hair from fully maturing. Finally, the follicle goes dormant and stops producing hair completely.
Can Hair Transplantation Really Help?
Hair transplantation takes advantage of the fact that men, who are affected by male-pattern baldness, do not experience the effects of hair loss at the back and the sides of their head. During the procedure, sureons remove healthy hair follicles from these areas and place them to areas of thinning. This procedure takes about 8 hours and is completely painless. Furthermore, advanced methods of hair transplantation eliminate any risks of scars.

Is Hair Transplantation a Permamanet Solution to Hair Loss?
Grafts transplanted during a Follicular Unit Extraction (FUE) procedure are immune to normal pattern hair loss processes. These grafts will remain with the patient, even if hair loss continues. Hair transplantation does not affect other, non-transplanted (original) grafts in the areas affected by hair loss. This means that in cases, where hair loss progresses further, causing more original hair follicles to fall out, a patient might need a repeat transplant 5-10 years later.
