itching and hairloss. I am waiting for reply desperately. Please help..

I am a 30-year-old male. I suffered from alopecia areata three years ago. Initially, there was a small patch without hairs, which grew big by time. I consulted many doctors and at last I found remedy where the hairs came back. Subsequently, at the end of that course of that medication, I developed rashes on several parts of the body, my face became swollen, skin scaling from my hands, although new skin came back now, and itching on specific areas like forehead, cheeks, chin, below jaws, neck, chest, armpit, abdomen, thighs, hands, legs, and even hair loss when combing from all over my head. After consulting various doctors, they prescribed some medication where if I take the medication, these rashes, etc. is not there up to 90%, but if I stop the medication it used to come back. Apparently, as the medication was steroids, I took it nearly 2 years and later came to know the steroid medication should not be taken for a longtime, so I stopped all medications. Now, also I am suffering from allergy not as severe as before up to 15%, although I can bear some how. Now, my big concern is hair loss, which is there throughout, I loose so much hair from my head when taking bath and while combing. The scalp can be seen now as the density of hair has become less than before, the scalp can be seen now. My father is not a bald and so i think hereditary may not be the reason. Sometimes I can feel eating eggs make my itching more and in sunny weather also. I want to know any remedy is there. These things are making my life miserable. Please help me to get cure and let me know if you want to know any more things. Kindly reply to this message and I am waiting for it desperately.
