Best Hair Loss Treatment doctors in Sahpurjat

Hello Sir, I am from Delhi. Its been eight months now my sister has beaten the deadly disease and is cancer-free now. She is 38 now. All her hair is shredded and honestly, there is no such growth yet. So after all the cancer trauma, she was already depressed and moreover had a hair loss issue. So we were thinking of getting her a hair transplant. Is that possible? Is there any risk for her to go through this?
