Klorane Shampoo With Nettle (£8) is an oil-controlling shampoo that works super effectively thanks to scopoletine, an extract from nettle, which helps to gently reduce excess sebum. Klorane promises that after sustained use, it regulates excess oil, which in turn, means you might find you don't need to wash your hair as much. On top of that, unlike some other oil control shampoos, this one also helps to detangle strands, too.
