My fine, wavy curls do well with a gentle sulphate shampoo and a silicone conditioner or styling product but I have started swimming twice a week and my hair is drier than it was.

I feel my silicone products protect from the chlorine a bit but would like to go back to using coconut oil as a pre-poo overnight on days I have swum, the question is, will the coconut get through the silicone or am I just wasting my time applying it?
