Association of Androgenetic Alopecia With Smoking and Its Prevalence Among Asian Men

Cross sectional quality of life assessment in patients with androgenetic alopecia

“…26 Su et al reported that risk for moderate or severe AGA increased for family history of first-degree and second-degree relatives, as well as for paternal relatives. 27 On the contrary, one study found a positive family history in 29.7% of men with AGA which is much lower than our results. This variation might be explained by genetic differences among populations and also to their lower study sample size.…”

“…In accordance with our findings, Yeo et al found that 64.1% of men had a positive family history 26 . Su et al reported that risk for moderate or severe AGA increased for family history of first‐degree and second‐degree relatives, as well as for paternal relatives 27 …”

Investigating the Relationship Between Androgenetic Alopecia and Hair Shape, Color, and Thickness: A Case‐Control Study

“…Furthermore, smoking reduces blood flow to the scalp, depriving hair follicles of essential nutrients and oxygen, which may exacerbate hair loss. The finding aligns with prior studies by Gupta et al [ 12 ] and Su and Chen [ 11 ], which also reported significant associations between smoking and AGA. For example, Su and Chen found that smoking 20 cigarettes or more per day nearly doubles the odds of developing AGA (OR = 2.34, 95% CI: 1.19–4.59).…”

“…This association may be attributed to smoking‐induced oxidative stress, which generates reactive oxygen species (ROS) that damage hair follicle cells, accelerate follicular miniaturization, and impair hair growth. Furthermore, smoking reduces blood flow to the scalp, depriving hair follicles of essential nutrients and oxygen, which may exacerbate hair loss.The finding aligns with prior studies by Gupta et al [12] and Su and Chen [11], which also reported significant associations between smoking and AGA.
