Particles around 100 nm can penetrate and stay in hair follicles without passing through healthy skin, making them safe for use in topical products and useful for targeted drug delivery.
The user mixes their own RU58841 solution and found that increasing the ethanol content improved absorption and reduced scalp itching. A study on minoxidil showed that penetration increased with higher ethanol concentrations, reaching maximum penetration at 90% ethanol.
The conversation is about whether castor oil can be effectively used alone after microneedling without a penetration enhancer like DMSO or ethanol. The user believes microneedling-induced wounds might be enough for absorption.
The user switched from an alcohol-based Minoxidil to a non-alcohol variant with oleanolic acid due to scalp dryness. They are concerned if the non-alcohol variant will be less effective for hair growth.
Enhancing minoxidil effects can involve using penetration enhancers like DMSO, urea, or retinol, and methods like dermarolling and adding substances like biotin and L-carnitine tartrate. Some users suggest trying higher concentrations of minoxidil if lower percentages are ineffective.
A user is considering switching from oral to topical finasteride to reduce systemic DHT impact and is exploring ethossomal finasteride for better skin penetration and potential hair regrowth. They found ethossomal finasteride in Brazil and are seeking opinions on its effectiveness compared to other topical delivery methods.
