Dear Swati,
See a doctor urgently to resolve this problem, as, the problem you are suffering, could be due to Psoriasis, or LOW IRON in the blood, or undiagnosed typhoid, depression and insomnia. If everything is found to be normal after the tests, then, try to keep your scalp [protected from sun and]clean, as, they say, cleaner the scalp lesser the hair problems. I had the same problem until two years ago, which I over came using keocarpin hair oil massage and washing the hair [avoid hot water at all costs] on every other day.
Good Luck, and be well,
Shweta Shetty.
