Tobacco and Hair Loss

I’ve read some articles that said smoking can cause vanes to constrict and possibly cause hair loss. I was wondering if there is any truth to that or not? Also do product like skoal and copenhagen also have this same constricting effect?

It is well known that smoking and tobacco products have adverse health effects. Nicotine in tobacco products are known to constrict blood vessels. This could lead to poor circulation and possible hair loss. To see this effect (of poor circulation) squeeze your nail bed until it turns white and see how quickly it returns to its natural pink color (it should be under 2 seconds). Compare the time difference after smoking a cigarette. You will see that the blushing time changes. Some hair transplants surgeons feel strongly that the effect of nicotine on scalp circulation is reduced more significantly when a hair transplant is done, leading to poorer growth of the grafts and less than idealized results.

It is remarkable to see how some people continue to smoke even with the Surgeon General’s Warning Label. I wonder what may happen if there is a Dr. Rassman Warning Label — “Warning: Dr. Rassman Has Determined That Smoking May Cause Baldness“
