Hello, If you have front baldness since last 3 and half years, we would suggest that you consult the dermatologist before the baldness level increases. He/She will be able to guide you through the root of your baldness problem. But remember, the eligible age for hair transplant is 25 years. So, the doctor might suggest PRP (Platelet Rich Plasma) therapy or medications as the first option as it is frontal baldness. If that doesn't work then he might suggest you opting for the option of hair transplant. Now, it is a little difficult to brief you about the exact cost of hair transplant in Kolkata but we can surely provide you with the approximate cost. The PRP therapy might cost you something between Rs. 4,000 to Rs. 15,000 per session. The cost of transplanting single hair graft can be as little as Rs. 35 per graft and can go up to Rs. 150 per graft. Moreover, the cost depends on per graft required, per sitting/session, technique opted, the technology used, the experience of the surgeon and the clinic. So be prepared for a 5 % to 10 % hike in the cost. And talking about the effect of hair transplant, once done, it is a permanent solution for baldness.
