Don’t you know that the way you brush your hair can also cause dandruff? So when you do the stroking of brushing your hair, make it right. One of the causes of dandruff is the oil clogs up your pores on your scalp; this is one of the ways that would cause your dead skin to accumulate. To prevent it to becoming dandruff, you should brush your hair from the roots to hair ends. This would help the oil in your scalp to spread fairly through your hair. However you have to be careful when brushing, make it gentle and not harsh because it may over stimulate the oil glands to work harder than it does normally. And it will make dandruff even worse.
