Hair Melanocytes as Neuro-Endocrine Sensors—Pigments for Our Imagination

Stress can lead to hair loss by affecting hair-follicle stem cells, and this loss is harder to recover from if one has male pattern baldness (MPB). Treatments like finasteride and minoxidil are used to address hair loss, but stress-related hair loss differs from androgenic alopecia.

Melatonin's effect on aromatase expression is unclear, with studies showing both increases and decreases. Hormonal impacts are complex and inconsistent, similar to changing health advice on other substances.

Topical melatonin shows promise for increasing hair density with minimal side effects. The user is transitioning from oral finasteride to a compounded minoxidil and finasteride solution and considering melatonin and bimatoprost as additional treatments.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

Osteopontin, a protein involved in hair growth on moles, may help with hair loss. However, it is also linked to Alzheimer's, cancer, and bone development, so caution is advised.

Melatonin is being explored as a hair loss treatment, with one user mixing it into minoxidil but not seeing results. The conversation discusses experimenting with melatonin concentrations.
