Still one of the most popular options in the UK, hair restoration shampoo can seem like the most simple and cost-effective way to counteract baldness. These products claim that the use of caffeine within the formula can not only prevent hair loss, but also stimulate hair follicles to promote growth. However the scientific basis of these claims remains unproven.Dr Kouremada Zioga verdict: “Without proper scientific backing there is no reason to spend your money on caffeine shampoos, which can be pricey when compared to an everyday shampoo. The use of ingredients like caffeine cannot trump your genetic makeup so if you are one of the 50% of UK men that suffer from male pattern baldness these shampoos will do nothing to counteract that. If you’re considering purchasing a new shampoo I would recommend investing in a SLS free option. It might not prevent your hair falling out but it will at least help protect the health of the hair you do have.”
