Simultaneous Analysis of Biomarkers in Human Hair for Evaluating Chronic Tobacco Smoke Exposure and Stress/Relaxation Using Online In-Tube Solid-Phase Microextraction Coupled with Liquid Chromatography–Tandem Mass Spectrometry

Nicotine use appears to increase hair shedding, with users noticing more hair loss when using nicotine and less when abstaining. Some users plan to quit nicotine and start treatments like finasteride and oral minoxidil to improve hair quality.

Nicotine may negatively affect hair by reducing blood flow due to its vasoconstrictor properties, but its impact might be minimal. Finasteride users are advised to avoid nicotine to prevent potential hair loss issues.

Nicotine use, especially from vaping, may worsen hair shedding and reduce the effectiveness of finasteride and dutasteride. Quitting nicotine seems to improve hair health.

The user has been using oral minoxidil and dutasteride for hair loss without success and is considering adding topical 17α-estradiol, Pyrilutamide, Clascoterone, or cetirizine. They have confirmed low serum DHT levels and are exploring additional treatments due to genetic sensitivity to DHT and prostaglandin D2.

Stopping nicotine might help hair health, but its impact varies by individual. Minoxidil and finasteride are mentioned as treatments used alongside nicotine use, with mixed results on hair density.

A user is experiencing worsening hair loss despite using 2.5mg Dutasteride, RU58841, and Minoxidil daily for over 8 months. They are concerned that daily nicotine from vaping might be counteracting the treatments.
