Hello Agnish, Welcome to health care magic. You seem to be having tanning of skin. However, you should also rule out internal problems like Addison s disease, anaemia,etc. please consult your dermatologist to rule out these internal problems. You could use a broad spectrum sunscreen every 3 hours a day. Avoid sun exposure between 11 am and 4 pm. Hair loss also has a lot of causes like anaemia, thyroid problems, stress, heriditary, etc. For hair loss, you could take supplements containing biotin. you can also use minoxidil solution after discussing with your doctor. Hope this helped. Take care.
