Nails and Hair

Hair loss may be linked to thyroid issues, with some individuals noticing changes in hair texture when taking substances affecting the thyroid. Treatments mentioned include a topical mix of finasteride, minoxidil, and tretinoin, along with microneedling.

A 35-year-old male experiences rapid hair loss on his head and body despite normal test results for testosterone, thyroid, and vitamins. He previously used topical minoxidil and retinol, and doctors have been consulted without finding a clear cause.

A 25-year-old experiencing hair thinning all over the body and head, despite using minoxidil and having low vitamin D levels, is advised to seek a second opinion from a dermatologist specializing in hair loss. The likely diagnosis is diffuse alopecia areata, which may require treatment with a JAK inhibitor.

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.

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.

The user has been using finasteride and oral minoxidil for two years without improvement in diffuse thinning and is considering switching to dutasteride and getting a scalp biopsy. Suggestions include treating subclinical hypothyroidism, trying PRP therapy, and checking for autoimmune issues.
