[/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Hair loss is called aloepecia. It has many causes and treatment depends on the cause. I would recommend you to upload the pictures of the affected areas under the premium section of the site so that I can have a clearer picture of the condition and can guide you accordingly. Hope I have answered your query. Let me know if I can assist you further. </s>
