Study of Thin Films and Nanoparticles Obtained by Self-Assembly of Block Copolymers and Their Interactions with an Oligo/Polysaccharide

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

The conversation is about using distilled water as a solvent for topical finasteride to reduce systemic absorption. The user is considering avoiding ethanol and propylene glycol to achieve this.

Hair loss treatments like finasteride, minoxidil, and RU58841 are currently available, but new developments are slow and often face skepticism. Despite some breakthroughs, such as hair cloning in Japan, a definitive cure remains elusive and potentially expensive.

The regimen includes using a diluted 5.5% Minoxidil / 0.025% Finasteride solution daily, microneedling weekly, and ketoconazole shampoo twice a week to minimize systemic exposure while maximizing scalp DHT reduction. The goal is to achieve hair regrowth with minimal side effects.

The conversation discusses using estradiol mesotherapy to replicate hormone replacement therapy results while minimizing systemic exposure. It also covers the use of Spironolactone cream, which reportedly has no systemic side effects, and the potential risks of using bicalutamide and Spironolactone in men.
