I think usually most people are not so observant when change happens gradually. I was even thinking that my results were not so good one time and then i went and looked back at my old pics and was shocked, it was worse than i remembered, lol. Sometimes when I have to show my student ID then people are very surprised.. one time someone asked me how old I was and after i told him he said "you do not look 27?!" and I said "well, I regrew some hair since last semester" and showed him my ID. His jaw dropped.
