research Examining the acceptability of providing hair or fingernail samples as a biomarker of physiological stress among older adolescents.
The study examined the acceptability of using hair and fingernail samples as biomarkers of physiological stress among older adolescents, with 110 participants aged 17-22. It found that 55.5% were willing to provide either sample, while 7.3% were willing to provide only hair or only nails. Willingness to provide hair samples was influenced by concerns about hair being cut and discomfort with hair collection, whereas nail sampling willingness was negatively associated only with discomfort with the idea of nail collection. Informational videos did not significantly change willingness. The study concludes that nail sampling is feasible for adolescent health research, with acceptability levels comparable to hair sampling, and highlights the need to address discomfort-related concerns to improve participation.

Microneedling combined with 5% Minoxidil and finasteride significantly improves hair growth compared to using Minoxidil or Minoxidil with finasteride alone. The combination treatment is safe and effective, but further research is needed due to small sample size and short study duration.
community Oral Biotin and Topical Minoxidil have a synergy effect in increasing hair growth, the study was only done in healthy subjects and it was only 14 days but it does prove that biotin can play a significant role as an adjunct treatment.
Oral biotin combined with topical minoxidil may increase hair growth rate, though the study was limited to healthy subjects and did not measure hair density. Some users report personal benefits from biotin, such as faster nail growth and healthier hair, but concerns about acne and study quality were also mentioned.
community Don't give up on finasteride folks
Finasteride may take over two years to show results and can cause side effects like sexual dysfunction and emotional changes. Alternatives such as dutasteride and minoxidil are discussed, with varying effectiveness and side effects.
