No, Hair Transplant is quite a safe procedure and don't cause such problem provided you concult experience doctor. With the advancement of technology there are many technique aviables for hair transplantation like Bio-FUE, PRP etc. that provide natural look.
I recommend you to select good clinic for hair transplant surgery that ensure good result. You could also check previous results and review of that clinic before finalising the date. Analyze the cost of hair transplant and grade of baldness first.
