5 / 1000+ results research The penetration efficiency of a dissolved model drug into hair follicles depends on the concentration of added nanoparticles
In this study, using an ex vivo porcine skin model, researchers found that a 4% nanoparticle concentration significantly enhanced the transport of fluorescein sodium into hair follicles compared to a 2% concentration, while higher concentrations did not further increase penetration depth.
research Ultrastructural alterations and environmental exposure influence the opiate concentrations in hair of drug addicts
This study observed that prolonged water or soil exposure can lead to significant reductions in drug levels in bleached and natural hair samples.
research The forensic limits of hair drug testing: a critical assessment of drug intake and hair concentration relationships
This review reports that hair analysis can confirm drug exposure but not accurately estimate doses due to variability and confounding factors like melanin and cosmetic treatments, suggesting it should be used as a qualitative forensic tool rather than for precise dose quantification.
research O1: Contribution of in-utero drug exposure when interpreting hair results in young children
This study found that analyzing hair samples in young children for drug exposure can indicate environmental drug exposure or in-utero exposure, but cannot definitively confirm deliberate drug administration.

5 / 1000+ resultscommunity Topical Finasteride concetrations and amount applied
Topical finasteride concentrations and application amounts are debated, with concerns that mainstream solutions may use arbitrary concentrations. A 0.25% solution with a specific application method is suggested as more appropriate than higher concentrations.
community New baldness drug boosts hair coverage by up to 86% in six months
A new extended-release oral minoxidil formulation claims to improve hair growth by maintaining steady blood levels, reducing side effects like hypotension, and potentially benefiting female hair loss. However, it is not considered groundbreaking as it builds on existing minoxidil treatments, and its effectiveness compared to current doses is debated.
community Dutasteride is a Miracle Drug.
Dutasteride is praised for improving skin and hair regrowth, with fewer side effects than finasteride. Users report mixed results on shedding and regrowth, with some experiencing enhanced libido and skin quality.
community Finasteride really is a miracle drug
Finasteride and minoxidil help maintain hair and slightly improve hairlines but are less effective at regrowing hair in bald areas, often needing a hair transplant for full restoration. Many users report no side effects and wish they had started treatment earlier.
community KX826 New Phase 3 Trial In China for 2025: 1.0% concentration
KX-826 is undergoing Phase III trials in China as a potential treatment for male pattern baldness, with some users considering it as an alternative or addition to finasteride and dutasteride. Opinions on its effectiveness vary, with some users reporting positive results and others finding it expensive and ineffective.
