Hair loss is a common issue that affects millions of people in the United States. While it's normal to lose some hair every day as part of the natural hair growth cycle, excessive or sudden hair loss can be concerning. Here are the five main causes of hair loss in the US:
1. Hereditary Hair Loss
Hereditary hair loss, also known as androgenetic alopecia, is the most common cause of hair loss in both men and women. It is estimated to affect 80 million people in the US. This type of hair loss is caused by a combination of genetics and hormones, and it typically results in a receding hairline and thinning hair on the top of the head.
2. Hormonal Changes
Hormonal changes can lead to temporary hair loss. This is often seen in women during pregnancy, after childbirth, or during menopause. Thyroid disorders, such as hypothyroidism or hyperthyroidism, can also cause hair loss.
3. Medications and Supplements
Certain medications and supplements can cause hair loss as a side effect. These include drugs that used for cancer, arthritis, depression, heart problems, gout, and high blood pressure. Excessive vitamin A intake can also lead to hair loss.
4. Medical Conditions
Various medical conditions can cause hair loss, such as alopecia areata, an autoimmune disorder that causes patchy hair loss. Scalp infections, like ringworm, can be lead to hair loss. Other conditions, like diabetes and lupus, may also contribute to hair loss.
5. Stress and Trauma
Significant physical or emotional stress can cause hair loss. This type of hair loss, known as telogen effluvium, usually occurs several months after the stressful event. Trauma, such as a severe illness, major surgery, or sudden weight loss, can also trigger excessive shedding.
If you are experiencing excessive hair loss, it's important to consult with a dermatologist or healthcare professional to determine the underlying cause and develop an appropriate treatment plan. In many cases, effective treatments are available to help slow hair loss and promote new hair growth.
