TLDR Smoking and drinking worsened hair loss in men with genetic hair loss, while eating and sleeping habits didn't; genetics played a bigger role than environment in hair loss.
In a 2014 study involving 3114 Korean patients with androgenetic alopecia (AGA), researchers found that smoking and drinking were associated with the severity of AGA in male patients, while eating and sleeping habits were not significantly correlated with hair loss severity. Both male and female patients with a family history of AGA had more advanced hair loss and males had an earlier onset. The study suggested that environmental factors have a weaker influence on AGA compared to genetic predispositions. However, the study's hospital-based design may not fully represent the general population, indicating a need for further community-based research.
