What can you do if had food poisoning 4 years ago and ever since then your hair has fallen out gotten very thin fine it used to be long thick?

If you believe your hair loss may be a result of food poisoning you experienced four years ago, it is essential to seek advice from a qualified medical professional or a dermatologist with expertise in hair disorders (trichologist). While certain toxins might impact hair growth for people undergoing specific treatments like chemotherapy, food poisoning does not generally cause long-term hair loss. Other underlying health conditions or issues may explain your symptoms such as nutritional deficiencies, autoimmune disorders, hormonal imbalances, genetics, medical treatments, stress, and lifestyle factors.
