Pericyte Plasticity in the Brain

The brain resists updating its perception of gradual appearance changes, like hair loss, due to its preference for stability and reliance on an internal model. This delay in perception can make changes feel sudden once the brain finally updates its model.

Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.

PP405 shows promise for hair regrowth by manipulating stem cell characteristics and lactate dehydrogenase, with Phase 2a trials pending. Google Ventures' $15M investment suggests confidence, but results and market availability remain uncertain.

The user tried various hair loss treatments for a year, initially using Hims foam min, Ketoconazole, dermarolling/microneedling, Biotin, Collagen, Caster and rosemary oil, and a multivitamin. From June, they switched to Keeps topical fin and min gel, Ketoconazole, dermarolling/microneedling, collagen, Caster and rosemary oil, and a multivitamin, and noticed hair thickening, especially on the front hairline.

Collagen peptides are recommended for hair and skin benefits, with users noting improvements in hair and skin health. However, evidence on their effectiveness for hair growth is inconclusive.

Aminexil/Kopexil may help reduce hair loss by addressing perifollicular fibrosis in androgenetic alopecia, but it lacks the extensive clinical backing of finasteride and minoxidil. Some users find it effective, but availability and cost are issues, especially in the US where it's not FDA-approved.
