<s>[INST] Hi I had stomach cancer September last year removed about 3/4 of my stomach did not need Chemotherapy but I am loosing my hair I have had blood tests but all OK I am 49 years old and weight is about 67kg can you help my why is my hair falling out? thank you [/INST] Hello and welcome to ChatDoctorConsidering your history there are two main factors - your history of illness and surgery that has put stress on the body, and-your age Since you have mentioned that your blood tests are all fine, we can rule out other causes. You may apply a hair growth serum like Tress go for the scalp. Consult your doctor before taking hair supplement capsules with biotin and iron. Your hair growth will take a few months to get better and come back to its cycle, and for hair fall to stop, since your body has gone through a lot. It is important to get as much nutrition into your diet as possible. Get rest, avoid stress. Age also will naturally slow down growth, and if genetic, you will be more prone to it. Do consult a dermatologist as well, to assess your type of hair loss and to give you treatment based on the results and if it suits your medical condition. If medical methods do not work well for you, certain new surgical procedures can be considered such as PRP. etc., as will be advised by your consulting doctor after observation, at a later date.Don't worry, give it some time. </s>
