6. Hair
Many of us – especially men – have a difficult enough time trying to hang onto our hair as we age, so why make it even worse by smoking? It’s been well-established that the numerous toxins in cigarette smoke don’t promote good health and that goes for the health of your hair as well. It is believed that the toxins may actually damage DNA in the hair follicles. Smokers are more likely to experience graying hair sooner and have more trouble keeping it as well.
