Current and Novel Methods for Assessing Efficacy of Hair Growth Promoters in Pattern Hair Loss

A 25-year-old male experienced significant hair loss due to telogen effluvium and androgenetic alopecia. He began using finasteride, minoxidil, and vitamins, seeing some regrowth but remains worried about hair density.

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 noticed small circular hairless spots after a buzz cut and has been using finasteride, dutasteride, and oral minoxidil for hair loss. They are experiencing continuous shedding and thinning, and it is suggested they consult a dermatologist for a scalp examination and possible biopsy to determine if it's alopecia areata or androgenetic alopecia.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

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.
