Hello,I Have Just Recently Realized I Have Huge Bald Spots

Hello,I have just recently realized I have huge bald spots on my scalp in a few areas I thaught it was probably allopecia since my mother has it ,but it is way bigger and getting worse by the day,also the hair that is growing back is completely white ,I am 34 yrs I have dark brown natural hair color not one gray yet ,question is I believe I could have been reacting to a side affect of a chemical,maybe something from my partner hey is around a lot of electricity and electronics
