A Morphometric and Histologic Study of the Scalp in Psoriasis: Paradoxical Sebaceous Gland Atrophy and Decreased Hair Shaft Diameters Without Alopecia

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.

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.

Subcutaneous scalp fat may be linked to hair loss, with theories suggesting that fat loss can lead to reduced blood flow and increased DHT activity, contributing to hair loss. Treatments discussed include PRP/PRF injections and fat transfer to improve scalp thickness and blood flow.

The user is experiencing progressive hair thinning despite using finasteride and dutasteride. A biopsy confirmed male pattern baldness, and minoxidil was suggested as an additional treatment.

The reduction in scalp oiliness is likely due to finasteride reducing DHT levels and the use of ketoconazole shampoo. The combination of these treatments may have decreased sebum production.

Sebaceous filaments or blackheads on the scalp are not a cause of hair loss; it's more likely due to hormonal factors, particularly in androgen-sensitive areas like the temples and crown. The user is using topical finasteride, minoxidil, and tretinoin for treatment.
