You might only think about your hair when styling it in the morning or when getting it cut or coloured. Or you might not think about it that much at all.

But hair (if you have any) is far more than just an outward expression of your personality. It can also tell you something about what’s going on inside your body, too. Whether you’ve too much or not enough, the way your hair grows (or doesn’t) can give you plenty of clues about your health. Here, physiology expert Dan Baumgardt explains what to look out for.

Glastonbury announced its lineup last week. While many people were buzzing about the female-dominated headliners that will be taking the stage this year, fans of Korean pop music were equally as excited by the fact that SEVENTEEN will make history as the first K-pop band to play the festival. It represents the realisation of a decades-long ambition by the South Korean government to make the country a cultural powerhouse.

And, while the US election is still months away, the battle for votes has already begun – and suburbia is proving to be one of the most important political battlegrounds to be won.

There are more college-educated people living in the US suburbs than there used to be, and this may be an important factor in how the vote splits.
