So true I just find a hair/body wash I like the smell of and I'm set, I buy separate shampoo and shit for the kids but for me I've always done it the man way and it's got me this far.
I'm fortunate, I've always had great skin was never even bad going through puberty, I only ever go spot n shit when I was taking far too many drugs, I'm 43 and I still got all my hair(I have gone grey as fuck though, I guess that's my payment) still wrinkle free too, I put it down to drinking 3-4 litres of water every day the last 20years even when I was a wreck head.
