I do like this serum (then again I like all things ghd!) but I dont like the price :/
It is a rather small bottle (50ml) for the amount you pay (at least R160). It really does smooth out split ends and tame frizz.. just only put it on mid lengths to ends else you will end up with oily looking roots. It doesnt weigh hair down at all. This would maybe be a once a year treat purchase for me with that price though.
