While smart supplements supports overall health, especially when combined with a balanced diet, overdoing certain nutrients may actually have a detrimental effect on your hair.<\/p>\n<p>Dr Ali, a hair-loss specialist, warns that <a href=\"https:\/\/www.inyourarea.co.uk\/news\/taking-too-many-supplements-may-harm-brain-neurologist-warns\" rel=\"noreferrer noopener\" target=\"_blank\">taking excessive amounts<\/a> of a few popular supplements can trigger telogen effluvium.

Dr Ali explains: \u201cToo much selenium can disrupt cellular balance and irritate hair follicles. People may notice brittle strands, patchy thinning, and other signs of toxicity such as nausea, vomiting, and nail brittleness or discolouration.\u201d<\/li>\n<li><strong>Vitamin E:<\/strong> Found widely in seeds, nuts, and plant oils, the general adult guideline is about 15mg per day. Dr Ali said: \u201cOvershooting that with supplements has been linked in research to increased hair shedding for some individuals, despite vitamin E\u2019s legitimate benefits in appropriate amounts.\u201d<\/li>\n<li><strong>Zinc:<\/strong> Essential for immune function and cell growth, this mineral often appears in hair-loss remedies, but balance is crucial. The specialist at <a href=\"https:\/\/uk-hairtransplants.com\/\" rel=\"noreferrer noopener\" target=\"_blank\">UK Hair Transplants<\/a> advises: \u201cYour body can\u2019t make zinc, but more isn\u2019t always better. Chronic high intake may actually worsen hair loss rather than help it. Balance is key.\u201d<\/li>\n<li><strong>Vitamin A:<\/strong> Important for vision and skin health, over-supplementation with Vitamin A can be particularly risky. Dr Ali said: \u201cExcess Vitamin A is a classic driver of hair shedding. People might also experience symptoms like vomiting, dizziness, or blurred vision when levels are too high.\u201d<\/li>\n<\/ul>\n<p><a href=\"https:\/\/www.inyourarea.co.uk\/news\/join-our-new-whatsapp-group-for-a-daily-dose-of-health-?utm_source=inyourarea.co.uk&amp;utm_medium=article&amp;utm_campaign=widget&amp;utm_keyword=wellness&amp;utm_content=article-widget-to-ww-article\/\" style=\"border:none\" target=\"_blank\" rel=\"noopener\"><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" id=\"app\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/04\/wellnesswatch-whatsapppromoapp.png\" alt=\"Obsessed with health?
