I would suggest using a really rich moisturiser as an aftersun on your head - I use Nivea extra rich moisturising lotion for dry skin instead of aftersun and never peel, it takes a while to absorb completely into your skin propery so might have a very shiney head for a while

other than that I generally find a body butter from the Body Shop (the cocoa butter isn't too highly scented) is rich enough or perhaps a thick E45 cream if you're fussy about smellies.... and slap loads of it on!
The only time I have ever used a branded "proper" after sun lotion was the year I went all scaley and peeled like mad.
All you need is a decent moisturiser and naturl yoghurt or aloe vera lotion to take the sting out of sunburn
