Hair extensions can make a beard look more manly, according to a study.
The discovery was made at the National Beard and Moustache Foundation (NBMF), a non-profit organisation which raises money to develop and deliver quality, affordable hair extensions for men.
Hair extensions, which come in various lengths, can be purchased online or in specialist hair shops, which are required to have a minimum of six weeks’ notice before the end of the year.
The NBMF, which is based in New York, has since raised over $50m for the organisation, including a $10m donation from Apple CEO Tim Cook.
The study, carried out by scientists from the National Institute of Standards and Technology (NIST), showed that the average cost of a single hair extension was $18 (£11.30), compared with $27 in 2012.
The average cost for the largest hair extensions is $55 (£38.80).
The average price for a hair clip is $22 (£18.40).
And the average price of a pair of extensions is just $30 (£24.80) for a six-pack.
The results, published in the journal Scientific Reports, were based on data collected by the NBMF in 2018.
The researchers found that people with a beard or a mane are likely to look more masculine, with their facial hair longer, their jawline wider and their upper lip slightly wider than a non bearded person.
The research also showed that men with a facial hair of at least six inches are more likely to be perceived as being manly.
They are also more likely than women to have hair extensions.
The latest research from NIST, which was funded by Apple, has been praised by Beard and Men magazine.
“The NBMF has done a remarkable job of creating an international, collaborative and well-funded project to identify and promote the benefits of hair extensions,” the magazine said.
“In our view, the NBMF is the best place to do this.”
