Smoking is not only a preventable cause of significant systemic disease but also affects the follicular growth cycle and fiber pigmentation. Ambient tobacco smoke exposure results in nicotine accumulation in hair follicles and the hair shaft. This review summarizes the evidence on the association between smoking and hair health, as denoted by alopecia and premature hair graying (PHG). In July 2020, a review of the literature using PubMed/MEDLINE and CINAHL databases identified 32 studies investigating the relationship between smoking, PHG, and alopecia (androgenetic alopecia and frontal fibrosing alopecia). The prevalence of hair loss and PHG is more prevalent in smokers than nonsmokers. Smoking is associated with negative effects on hair health as evidenced in PHG and alopecia. Smoking status should be assessed in patients who are presenting to their dermatologist for evaluation of alopecia and PHG.
吸烟不仅是导致严重全身性疾病的一个可预防因素，还会影响毛囊生长周期和毛发色素沉着。接触环境烟草烟雾会导致尼古丁在毛囊和毛干中蓄积。本综述总结了吸烟与脱发和早发性白发（PHG）所代表的头发健康之间关联的证据。2020年7月，一项使用PubMed/MEDLINE和CINAHL数据库的文献综述确定了32项研究，这些研究调查了吸烟、PHG和脱发（雄激素性脱发和额部纤维性脱发）之间的关系。脱发和PHG的患病率在吸烟者中比不吸烟者中更普遍。吸烟与对头发健康的负面影响有关，这在PHG和脱发中得到了证实。对于因脱发和PHG前往皮肤科医生处就诊的患者，应评估其吸烟状况。
