Thinning or sparse hair affects many people at some point in their lives. Many times the condition is temporary, other times, more permanent. The causes vary from person to person. Sometimes medication may be effective in treating the underlying cause, sometimes simply making a lifestyle change and other times, the situation is hormonal or genetic.
The most common cause of sparse hair in both men and women is a heredity condition in which sex hormones cause hair to fall out in a particular pattern. This condition is permanent; sometimes it can be treated or slowed with various medications. However, in some severe cases, a hair transplant is the only solution.
Certain medical conditions can cause hair loss. They include thyroid issues, scalp and skin disorders and alopecia areata where the body’s immune system attacks the hair follicles.
Sometimes, hormonal fluctuations can also lead to impermanent hair loss. It is very common that women, who are pregnant, have recently discontinued birth control or who are going through menopause experience temporary sparse hair.
Certain medications lead to hair loss as well. Drugs used to treat cancer, depression, heart problems, arthritis and high blood pressure commonly lead to hair thinning or loss. This condition can change with the discontinuation of the drug or treatment or the substitution of the drug causing the symptoms..
Hair loss is also tied to emotional and psychological sources and can result from physical or mental shock or ongoing stress.
To determine the most effective solution, the cause of the hair loss must be determined by a physician. Early attention to the problem may eliminate drastic measures later on.
