Several studies link smoking with more severe and earlier-onset pattern hair loss. The proposed mechanisms are plausible: reduced blood flow to the scalp, oxidative stress and damage to the hair follicle, and disruption of hormones — all on top of the genetic tendency you already have. Smoking is also linked to premature greying.
It's an aggravator rather than the root cause: genetics and DHT drive pattern loss, and smoking appears to accelerate it. Quitting won't regrow genetically lost hair, but it removes an accelerant and benefits the scalp's blood supply (and the rest of your health) — a worthwhile move alongside proven treatments like minoxidil and finasteride.

FAQ
Will quitting smoking regrow my hair?
It won't reverse genetic pattern loss on its own, but it removes a likely accelerant and improves scalp blood flow. Pair quitting with proven treatments for the best result.
Does vaping cause hair loss too?
There's far less research on vaping, but nicotine itself constricts blood vessels, so a similar effect is plausible. It's not a proven 'safe' alternative for your hair.
