[ALOPECIA]

Alopecia Areata A systemic autoimmune disorder against hair follicles . Ranging from small patches to total body hair loss , it’s a  poorly understood understood disease. Because it’s primarily cosmetic, without alternatively associated disease, it’s more about clinical diagnosis than management. Traction Alopecia Permanent scarring resulting in permanent alopecia that’s secondary to keeping the hair pulled tightly (extreme braiding) that puts excessive traction on the root. This is preventable  but irreversible once it occurs.

Fungus (Tinea Capitis) Areata (Alopecia Areata) Chemo Traction Alopecia Trichotillomania Male Pattern Baldness

Male Pattern Baldness A cosmetic issue whereby 5-DHT strangles hair follicles causing hair loss starting at the crown and working its way around to the front of the head. Treat with Minoxidil topical and Systemic Finesteride. Trichotillomania Trichotillomania is a psychiatric disease labeled under anxiety or OCD. It presents as patchy alopecia with hair at different lengths. Tell the girl to stop and do behavioral therapy to treat the anxiety. Chemo Sometimes the hair falls out. Chemotherapy targets rapidly dividing cells. This means the cancer (yay!) but also the gut (diarrhea), bone marrow (anemia, infection), and hair. Hair loss is expected, anticipated, and without treatment. Tinea Capitis Tinea Capitis is a fungal  infection that causes patchy alopecia on the head. All of the hairs will be lost at the same time, so all hairs in the affected region are gone or   are regrowing at the same length. A KOH prep  must be gotten to visualize the infection. Treat with topical and oral antifungals; failure to do so will result in permanent hair loss.
