Hey there! I had a hair transplant a few years ago, and I'll be honest, I was a smoker at the time. I ended up smoking a few days after the procedure, which I regret now. Smoking can restrict blood flow and slow down the healing process, so I definitely recommend holding off for a while.
I noticed that my scalp took longer to heal and the overall results weren't as good as they could have been. Plus, smoking can increase the risk of infections, which is the last thing you want after a transplant. Trust me, it's worth quitting or at least taking a break for a while to give your new hair the best chance to thrive. Hope that helps!
