    TLDR A 37-year-old man with hair loss and skin issues was successfully treated with oral antibiotics, highlighting the need for early treatment. Long-term care includes low-dose antibiotics and avoiding caps and wigs.
    In 2019, a case study was conducted on a 37-year-old African American man with a history of androgenic alopecia and acne keloidalis nuchae, who was diagnosed with folliculitis decalvans, a chronic disease causing severe hair loss and postinflammatory hyperpigmentation. The disease, which is not fully understood, likely involves an inflammatory response to Staphylococcus aureus. The patient was treated with oral antibiotics, reducing inflammation and bacterial load. The study emphasized the importance of early recognition and treatment to limit irreversible hair loss. Various treatments were mentioned, but their efficacy varied or they were used in limited cases. Surgical hair transplants were discouraged unless the patient had been disease-free for several years. Long-term management involved tapering oral antibiotics to the lowest dose that maintains remission and avoiding caps and wigs, which can harbor Staphylococcus aureus.

      Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
