Hair loss, also known as alopecia, is a common condition that affects millions worldwide. It can impact just the scalp or the entire body and may be temporary or permanent. The main causes include genetics, hormones, medical conditions, stress, and aging. While anyone can experience hair loss, men are more often affected than women.
What are the symptoms?
- Hair loss can show up in different ways depending on the cause
- Gradual thinning on the top of the head is the most common type
- Men often notice a receding hairline, while women may see a wider hair part
- Some develop round or patchy bald spots on the scalp, beard, or eyebrows
- Sudden and heavy shedding can occur after physical or emotional stress
- In certain conditions, hair may fall out from the entire body
- Scaly, red, or swollen patches on the scalp can signal an infection such as ringworm
- Hair loss may be temporary or permanent, depending on the underlying cause
Why does this disease occur?
- Hair loss happens when new hair does not replace hair that has fallen out
- The most common cause is genetic or inherited baldness
- Hormonal changes can trigger hair loss, including pregnancy, menopause, or thyroid problems.
- Immune system disorders, such as alopecia areata, may cause patchy hair loss
- Scalp infections, like ringworm, can lead to hair loss
- Hair-pulling disorders (trichotillomania) may contribute to hair loss
- Certain medications, including those for cancer, arthritis, depression, heart disease, gout, and high blood pressure, can cause hair shedding
- Radiation therapy to the head may result in hair loss, sometimes permanently

How is this disease diagnosed?

- A scalp biopsy may be done to check for infections or skin disorders
