Hair Loss

Hair loss, also known as alopecia, refers to the excessive shedding of hair from the scalp or other parts of the body. It is a common condition that can affect anyone, regardless of age or sex.

Types of Hair Loss

• Androgenetic Alopecia: Also known as male/female pattern baldness, this type of hair loss is caused by the conversion of testosterone to dihydrotestosterone (DHT), which leads to hair follicle shrinkage.
• Alopecia Areata: An autoimmune condition that causes patchy hair loss on the scalp or other parts of the body.
• Telogen Effluvium: A condition characterized by excessive shedding of hair after a major body stress, such as childbirth, severe illness, or extreme weight loss.
• Anagen Effluvium: Hair loss caused by chemotherapy, radiation therapy, or other medical treatments that target rapidly dividing cells.

Causes of Hair Loss

• Hormonal changes (e.g., thyroid disorders, polycystic ovary syndrome)
• Genetic predisposition
• Nutritional deficiencies (e.g., iron, zinc, biotin)
• Stress
• Certain medical conditions (e.g., autoimmune disorders, skin conditions)
• Medications (e.g., blood thinners, antidepressants)
• Hairstyling practices (e.g., tight braids, excessive heat styling)
