Wayne Rooney's hair transplant has been on the news lately. Just over a year after the treatment, his hair seems getting thin again regardless the fact that he paid £30,000 for the 'follicular transfer' treatment in Harley street hair clinic London.

It is a two-step procedure (Follicular Unit Extraction and Follicular Implantation) and supposed to be 'minimally invasive'. In theory, hair transplanted should grow naturally in the scalp in 6 month time after the treatment.
