My friend bought me some Opi nail oil a few months ago. And it is wonderful stuff. It smells divine and it makes your nails healthier and softens cuticles. I highly recommend it.
Also, I am going to contradict myself. I always used to think it wasn't worth spending much money on shampoo and conditioner. Well, I have changed my mind since using the L'Oreal Professional range for coloured hair. This really has made a big difference to my hair. It makes it softer. I've just ordered this special pack.
