Alopecia is a medical condition characterized by partial or complete hair loss in areas where hair would normally grow. This phenomenon can affect the scalp, eyebrows, eyelashes, or other regions of the body. Alopecia can manifest in various forms, each with distinct patterns and causes. One common type is androgenetic alopecia, often referred to as male-pattern baldness or female-pattern baldness, which is influenced by genetic factors. Alopecia, on the other hand, results from an autoimmune response where the immune system mistakenly attacks hair follicles, leading to patchy hair loss. Additionally, other factors such as hormonal changes, certain medications, stress, and underlying medical conditions can contribute to different forms of alopecia. The impact of alopecia extends beyond physical changes, often affecting individuals emotionally and socially. Management and treatment approaches vary depending on the type and underlying causes, and consulting with a healthcare professional is crucial for a proper diagnosis and tailored intervention.

What causes alopecia?
On average, people naturally shed between 50 to 100 hairs daily, a process that often goes unnoticed because new hair continually replaces the lost ones. The onset of noticeable hair loss occurs when the newly grown hair fails to adequately replace the fallen strands.
Hair loss is commonly associated with several factors, including:
Genetic Predisposition (Heredity): The primary cause of hair loss is often linked to hereditary factors, leading to conditions such as androgenic alopecia, known as male-pattern baldness and female-pattern baldness. This type of hair loss typically unfolds gradually, following predictable patterns like a receding hairline in men and thinning hair around the crown in women.
Hormonal Changes and Medical Conditions: Hair loss can result from hormonal fluctuations related to events like pregnancy, childbirth, menopause, and thyroid issues. Medical conditions, such as immune system-related alopecia causing patchy hair loss, scalp infections like ringworm, and the hair-pulling disorder trichotillomania, may also contribute.
Medications and Supplements: Certain medications used for conditions like cancer, arthritis, depression, heart problems, gout, and high blood pressure may have hair loss as a potential side effect.
Radiation Therapy: Hair may not regrow the same way after radiation therapy directed at the head.
Stressful Events: A considerable thinning of hair often occurs several months after a physically or emotionally taxing experience. Fortunately, this type of hair loss is generally temporary.
Hairstyles and Treatments: Excessive hairstyling, particularly styles that exert tension on the hair like tight pigtails or cornrows, can lead to traction alopecia, a type of hair loss. Additionally, aggressive hair treatments like hot-oil treatments and permanents may contribute to hair loss, with the potential for permanent damage if scarring occurs.
