Solvent-Containing Closure Material Prevents Follicular Penetration of Caffeine and Fluorescein Sodium Salt on Porcine Ear Skin

Topical finasteride in a liposomal formulation reduces systemic absorption compared to ethanol solutions. The user is seeking sources for such products, noting that popular options like morr-f are not liposomal.

The user is using 0.1% dutasteride, 1% minoxidil with 2% procapil and 0.005% caffeine in the morning, and 1% minoxidil with 2% procapil and 0.01% tretinoin at night. They are concerned about the solution vehicle's effectiveness in preventing systemic absorption and ensuring the products stay around the hair follicles.

Mixing RU58841 with cetosomal minoxidil is discussed due to scalp irritation from ethanol PG vehicles. A mixture of the two turned bright pink when left to dry.

PP405 and JXL-069 are the same compound, but users experienced no results due to flawed application methods. The topical gel formulation of PP405 is designed to target hair follicle stem cells effectively, unlike liquid solutions that fail to penetrate deeply.

The conversation discusses an experiment involving hair loss treatments, including the use of Verteporfin, KY19382, dutasteride, oral and topical minoxidil, AHK-Cu, and microneedling. The experiment aims to test the effectiveness of these treatments in promoting hair growth and healing without scarring, with updates planned every few months.

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.
