The reasons for losing a lot of hair can be varied and may include hereditary factors, hormonal changes, medical conditions, stress, nutritional deficiencies, or certain hair care practices. Here are some common causes:
- Hereditary hair loss (Androgenetic alopecia): This is the most common cause, often known as male-pattern or female-pattern baldness, usually gradually occurring with age or after hormonal changes like menopause.
- Hormonal changes and medical conditions: Conditions like pregnancy, childbirth, menopause, thyroid problems, alopecia areata (an autoimmune disorder), or scalp infections can lead to temporary or permanent hair loss.
- Stress and traumatic events: Physical or emotional shocks can cause temporary increased shedding of hair.
- Medications and treatments: Certain drugs for cancer, arthritis, depression, or heart problems, as well as treatments like radiation therapy, can cause hair loss.
- Nutritional deficiencies: Lack of essential nutrients like iron or protein can lead to hair thinning and loss.
- Hair care practices: Excessive hairstyling, tight hairstyles (traction alopecia), or chemical treatments can damage hair and cause it to fall out.
Normal hair shedding is about 50 to 100 hairs per day. If more hair than usual is falling out, it is advisable to consult a doctor to explore the underlying causes and appropriate treatments, which can range from medical interventions to lifestyle changes and hair care adjustments.
