Men, don’t worry about losing your hair as you age. It makes you look more powerful, according to research.

The bald look, adopted by Bruce Willis, Vin Diesel and Dwayne ‘The Rock’ Johnson, makes men appear more masculine, dominant, taller and stronger.

British star Jason Statham also sealed his status as a bald heartthrob with his recent engagement to model and former Victoria’s Secret angel Rosie Huntington-Whiteley.

Scientists have long debated the issue of hair loss in men, a billion-pound industry, with conflicting results on their perceived appearance.

The latest positive conclusion, based on three studies by University of Pennsylvania researchers, asked people of both sexes for their opinions.

The first study

In the first study, men with shaven heads were rated as more dominant than similar men with full heads of hair. Some 59 students took part, 35 were female.

The second study 

The second trial, involving 344 participants, of which slightly more than half were women, showed two images of the same men.

Those who had their hair digitally removed were perceived as more dominant, nearly an inch taller and 13 per cent stronger than their authentic selves.

The third study 

Researchers conducted the third trial on 552 participants. All were published in the Social Psychological and Personality Science journal in 2012.

Volunteers were given written and verbal descriptions about different men. Those with shaved heads got the highest marks for masculinity.

The bad news 

But it wasn’t all good news, the researchers added. Bald men looked almost four years older, the studies showed.

While men with shaved heads were viewed as considerably less attractive than their counterparts with full heads of hair.

Can the findings be explained? 

Writing in the journal, the researchers, led by Dr Albert Mannes, hypothesised that it could be because shaved heads are unusual, and people find average attractive.

They said: ‘Instead of spending billions each year trying to reverse or cure their hair loss, the counterintuitive prescription of this research to men experiencing male pattern baldness is to shave their heads.

‘Doing so will increase their interpersonal standing on a host of dominance-related traits, including their potential for leadership.

‘At the very least, these benefits may offer palliative relief from the psychological costs associated with natural hair loss.

‘These men might better improve their well-being by finishing what Mother Nature has started.’

What other studies have found 

This has been backed by a host of research. Last August, Johns Hopkins University scientists found that hair loss does reduce attractiveness.

Follically challenged men were rated as more youthful, attractive, successful and approachable after being given a hair transplant.

But Barry University, Florida, researchers discovered bald men look more socially mature, intelligent and honest in the eyes of the public.

Hair loss: The facts 

Male pattern baldness, the most common type of hair loss, affects around half of all men by 50 years of age.

It usually starts around the late twenties or by their late thirties. Figures suggest that men across the world spend £1.5 billion each year to stop their hair loss.

It is hereditary, and is thought to be caused by oversensitive hair follicles, linked to having too much of a certain male hormone.

It can also affect women – usually those who have gone through the menopause – and tends to cause hair to thin at the top of the head.
