does evolis actually work

I have been following Cellmid for a while now wondering whether I should purchase it or not. Being a person of mature age I am a little short in the hair department, so I thought I'd try the Evolis product first to check that I would be happy with the company, sort of like the Remington gentleman. I have been using it for 2 months now, but so far I can see no difference in the availability of hair. I was expecting luxuriant growth by this stage and having to spend my dividends on hair brushes and other sundry hair products. I have taken a range of photos so its not my lapse of memory either. Is it to ambitious to expect some changes in 2 months or do the changes take much longer. I notice on the Evolis website that the trials described there have been for 4 months. Have any other hotcopperites tried this product and what are your thoughts.
