The conversation is about the FDA approval of WINLEVI for acne treatment and the anticipation of Breezula, a hair loss treatment using the same active ingredient, which may indicate a positive future for Breezula's release. There is disappointment that Breezula's results are not optimal, but it is seen as progress in hair loss treatment.
Tretinoin may help more minoxidil convert to its activeform and could potentially increase its absorption, raising concerns about safety if too much enters the bloodstream. It's unclear if tretinoin affects finasteride absorption.
The conversation discusses skepticism about the effectiveness and formulation of a $10 RU58841 gel from a Korean brand, questioning if ethanol is used to hold the active compounds. Concerns are raised about the feasibility of selling it at such a low price.
Some people respond better to minoxidil due to higher enzyme levels converting it to its activeform. Minoxidil helps with hair regrowth but doesn't prevent hair loss; finasteride and other DHT inhibitors are needed for that.
A user is concerned about switching to a different formulation of minoxidil, but others reassure them that the active ingredient concentration is the same, so it should not cause shedding. Another user advises sticking to one brand, but no specific reason is given.
