Honest opinion and I can`t see the front of your head too well -- you only have a little moderate thinning at the crown....perfectly natural / normal for now ..... you don`t need to begin wearing this early....many guys would give their left arm to have the amount of hair you have ! I know you are probably very ` aware` of it, but the level of thinning on your crown wouldn`t merit a second glance from anyone for the moment !
