Answer:
The scientific reason is due to the creation of static electricity when a comb is moved vigorously through dry hair and as a result, dust and other small particles are attracted to the plastic comb.
Explanation:
When a comb is rubbed vigorously through dry hair, the free electrons of the dry hair move to the comb creating static electricity and the result is that the comb creates a negative or a positive pole. When a charged object is brought near a neutral object like dust, the electrons present in the latter are either repelled or attracted to the charged comb and they move and the opposite charge in the dust makes it possible for it to be attracted to the comb.
