Application of Validated UV Spectrophotometric and Colorimetric Method to Quantify Minoxidil in the Development of Trilayer Dissolving Microneedle: Proof of Concept in Ex Vivo and In Vivo Studies in Rats

User asks if washing hair or using hair fibers after minoxidil dries is okay and if dry scalp means full absorption. Some doctors and sources say 50-75% absorption occurs after an hour.

Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.

Microneedling combined with minoxidil and finasteride improves hair growth in androgenetic alopecia, with effectiveness varying by severity. The study was retracted due to concerns about validity and potential AI-generated content.

The conversation discusses using minoxidil and finasteride for hair loss, with concerns about absorption and considering adding tretinoin for better results. Microneedling is suggested as a method to improve absorption, with varying depths and frequencies recommended.

Minoxidil can be effectively delivered through nanoemulsions containing eucalyptol or oleic acid, enhancing its diffusivity and targeting hair follicles. This contradicts the advice against mixing minoxidil with oils in topical formulations.

The conversation discusses using Minoxidil and Finasteride for hair loss, with a focus on applying Minoxidil after microneedling to enhance absorption. There is also mention of considering oral Minoxidil due to potentially higher absorption rates.
