How Smoking Impacts on Hair Loss

Hair loss is a common concern among patients, and its underlying causes are often multifactorial. Environmental factors, particularly smoking, have been shown to negatively impact hair growth.

Mechanism

Smoking has been associated with some forms of hair loss. Proposed mechanisms include oxidative stress, altered circulation and inflammation, but much of the evidence is observational and does not establish the cause of an individual person’s hair loss.

Hormonal Impacts

Smoking may affect hormone pathways, but androgen levels alone do not explain pattern hair loss. Genetic susceptibility and follicle sensitivity also matter.

The Role of Smoking

Findings differ across studies. The cited hospital-based study of 103 men did not find an association between smoking and the age of onset of androgenetic alopecia. Avoid presenting this paper as proof that smoking caused earlier hair loss.

Considering a Permanent Solution

Stopping smoking benefits general health and is relevant to surgical planning. Whether transplantation is appropriate depends on the diagnosis, donor supply and individual medical assessment; quitting smoking does not automatically make someone a surgical candidate.
