While it is a reasonable hypothesis that smoking can cause hair loss, will giving up smoking lead to/assist in hair regrowth – or is the damage that has been done by smoking permanent? i.e is it reversible?
Thanks in advance.
Generally it is believed that damage from smoking is additive. We know that about the lungs, heart disease, and emphysema. We also know that for those that stop smoking, the additive impact does slow or stop, but the smoking-induced coronary disease or emphysema does not go away. Now if you extend that logic to hair loss, then by stopping your smoking, you may stop whatever balding smoking is causing, but it would not reverse.
