TNT: I don't understand your question...

But if you are asking if you'll get Emphysema from the hair chemicals, I'd say that is highly unlikely. When they say it takes years to develop a problem from being in a dirty environment, they are not kidding. It's amazing how resiliant the human body is. If you do get Emphysema, there is a about a 90% chance it will be from smoking. I'd say 9.5 out of 10 people I see have emphysema and other COPD from smoking. The fact that you have asthma doesn't help much either.
Just for thought:
I see all kinds of people and there is an amazing difference between a smoker at 65 and a non-smoker.
