Table S1. Disease-Dependent Differences Between Tape-Strip and Bulk Biopsy ssGSEA Scores Across Hair Follicle Compartments

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.

A dermatologist checked for hereditary hair loss using blood tests and plans to perform a trichogram. The user had slightly low Vitamin D3 levels, and the trichogram may help confirm androgenetic alopecia.

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.

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.

Genetic differences in hair follicles affect hair loss patterns. Treatments discussed include finasteride, dutasteride, minoxidil, and RU58841.

The user is experiencing a strange hair loss pattern despite using dutasteride for 3 years and minoxidil with tretinoin for 1.5 years. They recently added microneedling and are considering a scalp biopsy to understand the cause.
