Noticing hair loss can be a cause for concern. However, one health expert suggests that thinning hair could sometimes indicate a more significant problem than merely ‘ageing’.
Dr Eric Berg, who boasts over 2.3 million followers and more than 30 million likes on TikTok, as well as a staggering 14 million YouTube subscribers, highlighted the issue in a viral video. He informed viewers: « Thinning of the hair could be a biotin deficiency. » Biotin, also known as vitamin B7, is part of the B-vitamin family and aids the body in converting food into energy. According to the National Institutes of Health, biotin also plays a crucial role in maintaining the health of hair, skin and nails.
The vitamin assists in supporting keratin production, a fundamental protein that forms the structure of hair. The Cleveland Clinic explains that low levels of biotin can contribute to thinning hair or hair loss in some individuals.
Biotin is naturally present in a variety of everyday foods. The NHS states that eggs, nuts, seeds, salmon and sweet potatoes are excellent sources.
Many people obtain sufficient biotin through a balanced diet. The National Institutes of Health indicates that adults typically require around 30 micrograms of biotin per day.
True biotin deficiency is considered rare. However, the Cleveland Clinic reports that individuals with certain digestive disorders, long-term antibiotic use or genetic conditions may struggle to get enough.
Signs of insufficient biotin can go beyond thinning hair. According to MedlinePlus, deficiency may also result in brittle nails, skin rashes and fatigue.
Hair loss itself can have numerous potential causes. The NHS says stress, hormonal changes, genetics and certain medical conditions can all contribute to thinning hair.
One of the most prevalent forms is androgenetic alopecia, also known as male or female pattern hair loss. Research cited by the American Academy of Dermatology reports this affects millions of people worldwide.
Experts say anyone experiencing sudden or severe hair loss should seek medical advice. A GP can check for vitamin deficiencies or underlying health issues with simple tests and recommend appropriate treatment.
