<s>[INST] I m a 63 year old with a damaged liver. I have been dying my hair a dark brown for 23 years. I do not smoke, drink, or take any drugs over the counter or recreational . My liver number was 240, I understand it should be under 50. I have no pain, I walk 3 miles every day and drink lots of water. Could the dye have damaged my liver? I m 5 5 weight 135. I have no medical problems. I went for my yearly check up and blood work, and found out about my liver. [/INST] Howell come to ChatDoctorI really appreciate your concern, hair dye does not cause any harm to liver but of course this may cause anaphylaxis some time and this may be dangerous for liver, that is only matter of concern as long as hair color is concern, main chemical agent which may cause this is PPD (Paraphenylenediamine) and hair dye should be free from this, else this is nothing to worry, take care. </s>
