Hair color and personality

Many people tend to think that hair color influences personality. someone when her hair is dyed blonde will act different as before .Many people think being blonde makes a woman look more prissy, or ditzy or barbie like and brunettes are not necessarily more sophistocated,more mature, responsible and casual.Some girls are usually treated as ditsy people just simplely from their blonde hair. Why blondes give us this impression ? it is very hard to tell . some people think it is because in many movies ,these types are all in blonde .Maybe really hair color can influence personality ,but how can we explain this ? anyone can dye their hair any shade of color .so really very hard to explian . If hair color really works ,you don't even need to dye your own hair ,you can just wear colorful lace wigs ,then you can have different personalities . cheap lace wigs vendors
