Anyone experiencing sudden patches of hair loss could benefit from a trip to the dentist – according to university research.
Alopecia areata, which affects millions in the UK, is an auto-immune disorder where the body produces antibodies that attack the hair follicles.
The hair loss is often in small patches, which are sometimes barely noticeable. But if these patches join up they can become more obvious and lead to anxiety and loss of self confidence.
Also known as localised alopecia, it is estimated to plague around 65,000 people in the UK and can appear at any age – with 80 per cent of cases surfacing before the age of 40.
Stress is thought to be one one potential trigger, but it appears tooth infections could also be a cause according to research carried out by the University of Granada in Spain.
