Hi, Based on the history given you seem to be suffering from hypothyroidism for which your doctor has prescribed the correct medications. Hair loss is usually associated with hypothyroidism and it may also occur during the first few months of treatment with Euthyrox. This effect is usually temporary as your body adjusts to this medication. Generally these medicines are safe and well tolerated however the following side effects may occur: Euthyrox may cause increased sweating, sensitivity to heat, nervousness, mood swings, tiredness, diarrhea, tremors, and headache. Mecozen Plus which contains multivitamins and minerals are usually added to correct their associated deficiency states. Whereas Androfol-M is a Biotin supplement which supports hair growth and therefore it is prescribed. As long as you take Euthyrox your hypothyroidism will be treated and take other medications along with a nutritious diet to regain the hair color. Hope this answers your query. Let me know if I can assist you further. Regards, Dr. Mohammed Taher Ali
