Alopecia and Hair Loss
When hair loss is excessive or unexpected it is referred to as alopecia.
Both men and women may experience the condition in varying degrees, from a gradual thinning to complete baldness.
Many factors may contribute to hair loss. In cases in which the hair loss was the result of an illness, stress, or a nutritional deficiency, the hair will typically grow back after the contributing factor has been managed.
The most common type of hair loss is inherited, known as male-pattern or female-pattern hair loss. With this type of hair loss, men generally develop bald spots in the front, crown, and sides of the hairline, and may become completely bald. Women may experience some thinning all over, but mostly on the top of the head. This type of hair loss is usually permanent.
Hair loss is common, and can be difficult to live with. However, in many cases it is treatable and even sometimes reversible.
Many forms of hair loss do not require any treatment to resolve, and the hair will start to regrow on its own. However, there are types of hair loss that lead to permanent baldness. These can be slowed significantly through regular treatment. Common treatments include lasers that stimulate hair growth, prescription medicines, injections, and scalp treatments.
