research In Silico Modelling of Transdermal Delivery of Macromolecule Drugs Assisted by a Skin Stretching Hypobaric Device
The simulation showed that hypobaric pressure improves drug delivery through the skin, but stretching alone doesn't fully explain the increase.
research Quantifying Polymer Deposition on Hair Fibers by Microfluorometry
Microfluorometry effectively measures how much polymer coats and penetrates hair, useful for evaluating hair products.
research Integument Pattern Formation Involves Genetic and Epigenetic Controls: Feather Arrays Simulated by Digital Hormone Models
Feather patterns form through genetic and epigenetic controls, with cells self-organizing into periodic patterns.
research Penetration of Drugs Through Skin: A Complex Rate-Controlling Membrane
The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.

5 / 78 resultscommunity Dutasteride takes 1-3 months to work in the scalp. Not weeks. Be careful.
Dutasteride takes 1-3 months to affect scalp DHT levels, not just a week. The prostate absorbs Dutasteride faster than the scalp due to different vascular networks and enzyme densities.
community How come Dut doesn’t cause more brain problems than fin if it inhibits Type 1 5AR?
Dutasteride and finasteride have similar risk profiles despite Dutasteride blocking more types of 5AR in the brain. Some users report no mood issues with either drug, and it is suggested that Dutasteride's larger molecular size may limit its ability to cross the blood-brain barrier.

community 18 Months Minoxidil 5% Before & After
The user used Minoxidil 5% for 18 months, seeing improved hair density but no change in the crown area. They are cautious about using Finasteride again due to past gynecomastia.
community FCE 28260: A Forgotten 5α-Reductase Inhibitor
FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.
