I bought the little tube yesterday (£1.95 in Boots) and tried it last night. You put it on dry hair, rub it in well then just leave it, and wake up with gorgeous soft hair!
I was worried that it might leave my hair greasy looking and lank, but it really hasn't. I did keep away from the roots though. It smells fab as well
The bigger tube is £4.99, I'll be buying one when my little one runs out.
