Because the probability of the comb breaking the scalp is too small, the wound will not be deep, generally will not have blood, let alone will not be used at the same time, it will dry at intervals.

... When the red mole on the head was pushed out of the blood, worried about the person in front of in case it is hepatitis B virus.
