Looking for a specific fairy tale collection book

[Trillian]

Doesn't have the cover you describe but you could try Angela Carter's book of Fairy Tales which has different tales from around the world (I believe it was published in the early 90s in different volumes).

There is a book called Frog Prince and Other Stories, but doesn't seem to be what you are looking for: https://www.goodreads.com/book/show/1...

I also found a Frog Prince and Other Frog Tales but publication seems too late https://www.amazon.co.uk/Prince-Other...

although there is also a related website which might help identify the tale you remember: http://surlalunefairytales.com/

The oil hair one is referenced here but i know the edition is too new but maybe having the story you remember will help?

Here's another close but not quite it book: The Illustrated Book of Fairy Tales
