PRP for Hair Loss + Smoking Q&A

Hi, I'm 24 years old, male. I have been experiencing hair thinning and shedding in the last 7 years. I experience hair loss day by day. I want to use PRP as a good treatment but unfortunately I smoke 4 to 5 cigarettes per day. Does the smoking affect the PRP process or should I stop smoking before going through the process?

Is PRP effective? Smoking during PRP? Can I have proper hair growth to some extent? Should I hope for hair growth? I am also using finasteride for alopecia and revivoderm as supplement.

I am heavy smoker want to go for prp for hair loss, will heavy smoking affect the treatment? I am planning to stop smoking altogather before treatment. I am on NW 3 scale at present?

More concerned about the top but the forehead is also an issue..I had a good low hairline when I was young how low its possible to make a new hairline.. I am 31 smoker of tabaco and legal stuff..been using a 0.5mm derma roller if you notice redness in some pics that is because of the roller..its been almost 3 4 months not much improvement I found.. How many grafts? Check my pics..have marked a desirable hairline is that possible?? Hopefully I am not too late am I?

I have been informed that nothing you do to your body can help or hurt the overall outcome of this treatment, but I am asking just to be sure.
