Shampoo

Su questo episodio

<p>Shampoo ranges hugely in price, from own brand bottles to premium products that promise to improve your hair, leaving it in better condition, stronger and shinier. But can they really deliver?</p><p>Listener Sophie sent in a WhatsApp to ask just that, as well as whether we should use different shampoos depending on our hair type, if sulphates or parabens could be harmful to our hair, and if shampoo bars can do the job just as well, and be a greener option? </p><p>Greg Foot untangles some of the most common claims by speaking with a clinical Trichologist (someone who has studied the structure, function and diseases of human hair) as well as an expert chemist and pharmaceutical analyst. </p><p>This series, we’re testing and investigating your suggested wonder-products. If you’ve seen an ad, trend or fad and wonder if there’s any evidence to back up a claim, drop us an email to <a href="mailto:sliced.bread@bbc.co.uk">sliced.bread@bbc.co.uk</a> or you can send us a voice note to our new WhatsApp number: 07543 306807.</p><p>PRESENTER: Greg Foot PRODUCER: Kate Holdsworth</p>
