Follicle challenge

Find out why we have bad-hair days at this new exhibition exploring the science behind our scalps.

It examines the biology of hair - including the forensic capabilities of one single strand in identifying your race, diet and behaviour. You'll also find out how fashion and culture have influenced both the cuts we choose and the products we use.

Useful features for the folliclely challenged include the chance to analyse your own hair health under a video-microscope or try 40 styles in the virtual hair salon.
