Canities Subita: Sudden Blanching of the Hair in History and Literature

A user noticed irregularities on their scalp using a digital microscope and suspects scarring alopecia, despite using minoxidil and finasteride. Other users suggest seborrheic dermatitis as a possible cause and recommend treatments like ketoconazole shampoo, sulfur soap, selenium sulfide shampoo, and apple cider vinegar rinses.

The user is experiencing diffuse thinning and inflammation despite using 2.5mg dutasteride daily, ciclopirox, and ketoconazole shampoos. They are considering treatments like hydroxychloroquine and JAK inhibitors due to suspected scarring alopecia and have faced challenges in obtaining a scalp biopsy.

A 19-year-old female with Diffuse Alopecia was advised by a dermatologist to use vitamin supplements, a hair serum, and antifungal drops, leading to some improvement. Other users suggested treatments like minoxidil, microneedling, and consulting a different dermatologist for further advice.

A user observed orange fluorescence on their nose and hair under a black light, indicating Cutibacterium acnes, which may contribute to hair loss alongside androgenic alopecia. A suggestion was made to use coal tar shampoo to address the issue.

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

Hair loss treatments discussed include microneedling, minoxidil, tretinoin, finasteride, dutasteride, pumpkin seeds, saw palmetto, and scalp massage. The consensus is that finasteride or dutasteride is necessary for significant regrowth, while other methods may only slow hair loss.
