When you take a close look at a bottle of shampoo, you're likely to see a long list of complicated ingredients.
In many shampoos, this list may include detergents, preservatives, and artificial fragrances and colourants. Some of these are potentially harmful chemicals that could cause health problems ranging from skin irritation to headaches.
Parabens are chemical preservatives and are a common ingredient in all kinds of cosmetics. They've been used in shampoos for years – but recently have come under scrutiny by scientists and researchers, as there are concerns they could be linked to cancer.
Chemicals like parabens can be absorbed by the skin – so many people prefer to use chemical free, natural products to reduce the risk of health issues caused by toxic ingredients.
Luckily, there are some superb natural, paraben-free and organic products on the market – and many are affordable and readily available.
We've tried and tested some super natural shampoos – here are six of our favourites.
