Too much dandruff is bad. It can choke your hair and prevent hair growth. We should all get dandruff checks. Little kids are excellent at getting off your dandruff. They will use their hands and get off excess dandruff. You want healthy hair to keep warm in Antarctica- or on a sweltering cold winter day. Go dandruff checks!
Pointed dandruff checks as a discreet health and grooming exercise are specious. Every time we brush our hair, dandruff is launched into the air and sticks to the hair on the brush. More to the point, any time someone with dandruff wears a dark shirt or jacket, it would shows up on the shoulders.
