See reply from InCider below. I've noticed Rooneys hair actually looks different every time I see him, it's to do with the concealer. Also they clearly aren't old photos; in the second photo he's wearing an Everton top and he only signed for Everton this season.
I do feel a bit sorry for him actually. For all his money, talent and fame he's obviously very insecure about his hair. It goes to show that if you have this kind of aggressive hair loss you're completely fucked even with all the best treatment
. Also I can verify what you say about wavy hair. I'm about a Norwood 2.5 possibly 3 with recession at the temples and thinning at the front middle but because I've got thick, wirey hair it gives great coverage when I grow it out. I always have a wry smile when it's longer and I get comments about my "thick curly hair"!
Also, Rooney lives in the laddish, macho world of Premier League football. You can bet your bottom dollar he would have had to put up with relentless jokes and micky taking from his team mates when he started to lose his hair at such a young age.
