So after much trial and error I heard about Coconut Oil. You can buy this in your local chemist for about €4. At room temperature it is solid - as below
If your hair needs a little(or a lot) of conditioning, spoon a little of this onto your hand, the heat of your hands rubbing together will turn it in to an oily paste and you can then work it in to your scalp and hair.
I normally put it in to my hair before going to bed (don't use your finest pillowcases however) and wash it out well the next morning, my hair is lovely and soft and conditioned afterwards!
Give it a go! At €4 you can't go wrong
