Scalp Microbiome and Its Influence on Alopecias: Current Evidence and Therapeutic Perspectives

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.

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.

Gut microbiome imbalances can cause scalp inflammation and affect hair follicles, potentially leading to hair loss. Treatments include finasteride, peptides like BPC-157, TB-500, KPV, and lifestyle changes such as diet and exercise.

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

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.

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.
