Sir, I am having hives for last four years and I am very much in pain form this and even my hair been damage, by getting it white and even hair loss, so help through it.

Question

Hives often appear suddenly on any part of the body. They may appear in one place, go away in a few hours and then come back in another place. In severe cases, hives may come and go for several weeks.
White hair at an early age, called premature greying is a common condition affecting the young population in all races and life style conditions. The cause of greying is the loss of melanin, the pigment that gives colour to your hair. This loss of melanin usually occurs at old age but nowadays it can occur in younger ages due to lifestyle changes and the environmental pollution. It is proven that the genes and the genetic changes can also cause this as well as stress which is high in these days. There are multiple commercial preparations like creams and powder calming to be reversing the hair whitening but are all of dubious values. Here I can suggest some natural and homemade methods for changing the grey hair to black which is harmless even if not very great as you would want it to be.
Lack of vitamins like B, zinc, iron copper & iodine is known to cause greying of hairs. So in your diet include all these vitamins.
Avoid junk food, and eat a balanced diet with all these vitamins  
Keep the scalp clean, and avoid using soap or shampoo.
Apply coconut oil and leave it there and just allow it to dry without washing off with soap or shampoo. 
Avoid caffeine, alcohol, and reduce stress by meditation and yoga or reading books or listening to music 
1)	Massage with onion paste, regularly 
2) Eat sesame,
3) Apply butter oil and massage scalp 
4) Regularly wash hair with gram flour, and curd/milk mixture
5) Do not forget the vitamins listed above and eat healthy as suggested.
There are some Ayurveda preparations for grey hair like Amla paste, 
Apply coconut oil, and curry leaves the paste 
You can also try coconut oil and lemon.
Using Henna and coconut oil is also excellent. These home remedies will help you great with grey hair and are harmless unlike commercial preparations
