No – you can’t "catch" dandruff nor can you pass it on to anybody.
In fact, everybody already has all the factors that cause dandruff on their scalp – a microbe called Malassezia globosa and natural oils, known as sebum.
What makes someone suffer from dandruff is sensitivity to these factors. This is something that can’t be passed from one person to another so there’s no chance of catching dandruff from a sufferer or passing it on to someone else if you’re suffering from it.
