    TLDR Liposomes can make the antiandrogen RU 58841 more effective for skin application by reducing absorption, increasing skin retention, and targeting sebaceous structures.
    In 1995, a study was conducted to compare the absorption and distribution of a new antiandrogen, RU 58841, when included in liposomes or in solution. The study found that liposomes significantly reduced the percutaneous absorption of RU 58841 compared to the solution, but resulted in slower permeation of the drug and a longer duration in the skin. Liposomes also led to an accumulation of the drug in the sebaceous structures. The study concluded that liposomes could be more favorable for topical application as they reduce absorption, increase retention of the drug in the skin, and target the sebaceous structures.

      The conversation discusses a new liposomal topical finasteride from Hasson and Wong, available in Canada and Italy, soon in the US, costing $40/month. It claims to reduce scalp DHT by 50% without affecting serum DHT, potentially benefiting those who can't tolerate oral finasteride or RU58841.

Suggestions include simplifying the routine, possibly increasing minoxidil dosage, and considering alternatives like RU58841, while cautioning against using estrogen due to potential side effects.
