If you're a bald man, this may make for uncomfortable reading.
A study reported in the Daily Mail has confirmed that hair loss reduces attractiveness, and bald men were also rated as less successful and approachable.
The research, carried out by Johns Hopkins University in the US, involved asking a group of 122 participants to rate 13 pairs of images.
The photos included 'before and after' pictures of seven men who had undergone hair transplants, and another six pairs of images of balding men whose appearance had barely changed between each shot.
The volunteer group, made up of roughly half men, were then asked to give marks out of 100 for a range of percieved traits, such as attractiveness, successfulness, and approachability.
