The density, tissue and hair quality of beard is completely under the control of genes. After the beginning of puberty, beard hair gets thicker and gain their terminal forms in three years. Loss of beard and moustache may be due to autoimmune diseases as well as cutaneous diseases. Other than this, the heaviest picture arises from hormonal imbalances.The virility hormone testosterone should be controlled when it decreases below the threshold value in men. Loss of beard may also be observed in the disease called alopecia areata.
(There is no cosmetic or medical treatment to grow hair in areas without hair, yet. This is also valid for beard and moustache. Beard and moustache transplantation can be performed from the age of 20-22 when the hormones reach their basal level. This procedure is recommended for men who wish to grow their side whiskers, like the appearance of a beard of two days, but have irregular or deficient beard hair.)
(Beard-moustache transplantation can be performed in all healthy men who have no beard or who have bald regions in patches in their beard. One of the most common interventions is transplantation in a region with a scar. Beard-moustache transplantation can be performed in anyone who has hair on the scalp. The Procedure is performed by extracting hair roots from the area between the ears (just above the neck with thinned hair) or the areas above the ears.)
(Approximately 8-10 weeks after the intervention the outcome starts to display itself. The beard hair which is present and scalp hair which is transplanted cannot be visually differentiated. The outcome is natural and persistent.)
