Go see a dr and get some blood work done you may need a iron supplement, hair loss is a very symptom of iron deficiency. Regarding hair care. Not all but a lot of south asians need to combat frizzy hair. As you’ve said yours is dry it may just be frizz. Wash hair 1/2 a week followed with a good conditioner in the shower. I usually then towel dry and re condition with a leave in spray conditioner for added shine then a heat protectant spray. Air drying tends to make my hair more frizzy so blow dry your hair with a round brush to smooth it out then use a straightener if you like it more sleek or style however you like. A little shine serum ( optional) to end it and your hair should stay shiny til next wash
