Hi, I Am 28 Years Old Female Suffering From Excessive

Hi, I am 28 years old female suffering from excessive hair loss since more than a year. My hairs are very dry (even after shampooing and conditioning), frizzy, wirey, separated and not smooth. Hair fall occurs on every hair wash, oiling, head massage, however combing hair leads to hair breakage. I never use hot water to wash my hairs, i never comb wet hairs and use proper coconut oil and good shampoo/conditioner for my hair, unfortunately there is no effect on my hairs. I am taking protein rich diet, drink plenty of water, also includes green tea in a day. I recently consulted one of the doctor, she prescribed me to take homoeopathic Rx - Schwabe's Wiesbaden 200/ twice a day for 1 month and Follihair tablets (multivitamin) - 1 tab. daily once for 1 month. Investigations she advised:
Get your blood tested for (empty stomach) - CBC, S. Iron, S. Folic acid, S. Ferritin, S. Calcium, S. Vitamin D3, S. Vitamin B12. I have just started taking those tablets. How to get rid of severe hair fall, I have never been suffering from hair fall before. Is there any medications to stop further hair fall. I have experienced that my density of hairs are getting less and can see bald patch in front areas :'(. Please help
