Alopecia generally refers to hair loss on any part of the body. However, in its most common form, known as androgenetic alopecia, it refers to a process of gradual hair loss mainly affecting men: one third of men by age 30, nearly half by age 50. The latter is also more commonly known as baldness.
Alopecia is often linked to a hormonal imbalance, particularly in humans with a surplus of male hormones that accelerate the aging of the hair. Androgenetic alopecia takes the form of hair loss that primarily affects the sides of the forehead, temples and / or top of the skull. Other types of alopecia exist and can take the form of a sudden and rapid hair loss affecting only certain areas: this is called alopecia areata. The disease can also manifest itself as a widespread and rapid hair loss that is the aftermath of a specific problem (infections, childbirth, surgical shock: this is called telogen effluvium). Alopecia can also be caused by fungi called tinea, though this form is seen primarily in children..
A simple consultation with a general practitioner or a dermatologist (which can, if necessary, be complemented with a capillary sample exam with some hair taken from different areas of the scalp), will often determine the type of alopecia present.
Alopecia has no hazardous effect on your health; the damage is therefore primarily cosmetic. Hair loss can indeed be resented, seen as premature aging, and a source of patient discomfort or lack of self-esteem. Psychological care can be quite useful against this traumatic event. In androgenetic alopecia, certain drugs such as finasteride (never to be used by women) or minoxidil may be proposed to curb the effect. Wigs are also an aesthetic solution. Finally, surgery, with the placement of hair transplant implants, requires a larger budget but can also help your reach a satisfactory cosmetic result.
