Does smoking cause hair loss?

Im having hair fall for a while and i didnt realize that im having a lot of hair loss and i know its not normal, the reason might be the contraceptive pill that i used to take but i stopped it three months ago and i still have it.


Does smoking ciggarettes causes hair fall? please advise ...thanksDoes smoking cause hair loss?
im not sure if its a actual side effect... but a friend of mine used to always say that you could tell when he stopped smoking cos his hair would grow back (he used to stop and start again alot).. it could just be stress... or alopecia, or just not eating healthy.





by the way.. its not really a question for the STD section!Does smoking cause hair loss?
I've smoke pot for about 20 years, thought my hair loss was because I was getting older, I 've quit for two mounths now to get a better job, and my hair is starting to come back now, sadly, yes smoking does cause it. I don't think I'll smoke anymore. can't beleve I'm saying that, but it's true.

Yes it does. Smoking will kill you and when you are dead your hair will fall out.
Can smoking affect hair loss?





The answer may be yes. According to a recent study by the Harvard School of Public Health, smoking can increase almost all the major androgenic hormones including DHEA, androstenedione, testosterone, and dihydrotestosterone (DHT), the hormone most closely linked to hair loss.





The study, which examined a cross-section of 1,241 randomly sampled middle-aged U.S. men, compared hormonal levels of nonsmokers and smokers. The study made made sure that weight and age were not a factor in the study results. According to the study, dehydroepiandrosterone (DHEA) was 18% higher in smokers, dehydroepiandrosterone sulfate (DHEAS) was 13% higher in smokers, androstenedione was 33% higher in smokers, testosterone was 9% higher in smokers, and DHT, the hormone most closely linked with hair loss, was 13% higher in smokers. Although the study did not study hair loss specifically, it is commonly accepted that DHT is the main hormone associated with hair loss.





Propecia, the oral pill for hair loss, works by blocking testerone from being converted into DHT. Increasing levels of Testosterone and DHT are known to be associated with an increase in the amount and rate of hair loss. Smoking alone will not make someone not predisposed to lose hair start losing hair, nor will stopping smoking prevent your hair from falling out if you are predisposed to hair loss. However, if this study is correct, it is possible that smoking may increase the rate at which your hair does fall out and possibly the amount.
