Doctors Near You for Alopecia in Sao caetano do sul

Alopecia is a medical term for hair loss, which can occur on the scalp or any part of the body. Hair loss can range from thinning hair to complete baldness and may be temporary or permanent, depending on the underlying cause. There are various forms of alopecia, including androgenetic alopecia (common baldness), alopecia areata (an autoimmune disorder leading to patchy hair loss), and traction alopecia (hair loss caused by tension or pulling on hair). The causes of alopecia are diverse and can be linked to genetic, hormonal, autoimmune, environmental, and lifestyle factors. Androgenetic alopecia, the most common type, is primarily influenced by genetic factors and hormonal changes, particularly an increased sensitivity to dihydrotestosterone (DHT), a derivative of testosterone that affects hair follicles. Alopecia areata occurs when the immune system mistakenly attacks hair follicles, leading to hair loss. This condition can be triggered by stress, illness, or a genetic predisposition. Traction alopecia results from hairstyles that pull on the hair, such as tight braids, ponytails, or extensions, leading to follicle damage and hair loss over time. Other causes of alopecia include nutritional deficiencies (such as iron or protein deficiency), certain medications (like chemotherapy or steroids), thyroid disorders, and scalp infections like ringworm. Treatment for alopecia depends on the type and cause of hair loss. For androgenetic alopecia, medications such as minoxidil (a topical treatment that stimulates hair growth) and finasteride (an oral medication that reduces DHT levels) are commonly used to slow hair loss and promote regrowth. Alopecia areata may be treated with corticosteroids (either topical or injectable) to suppress the immune response and encourage hair growth. In some cases, topical immunotherapy or other immunosuppressive agents are used. For traction alopecia, modifying hairstyles to reduce tension on the hair and avoiding further damage are key. Nutritional supplementation may be recommended for individuals with hair loss due to deficiencies. Hair transplant surgery is an option for those with significant hair loss who do not respond to other treatments. Additionally, supportive measures such as wigs or hairpieces can help individuals manage the cosmetic aspects of hair loss. A healthcare provider can help determine the most appropriate treatment based on the specific type and cause of alopecia.
