I know Maz! It is a disgrace, but people honestly think you need all these bottles of crap!

M2R - use olive oil, massage it into his head and leave it on overnight, pop him in a shower cap and wash it off in a warm bath in the morning. You'll need to keep doing it unti it goes away... I still get cradle cap now sometimes lol

And don't use shampoos or soaps on his head as they will dry it out.
