Earwax is produced by modified sweat glands and most of the differences in the rate of wax production are genetic, although skin conditions such as psoriasis and eczema can also affect it.
Wax works its way out of your ear canal naturally, and when earwax builds up, it’s usually because this clearance mechanism isn’t working, rather than because you’re producing more wax.
The ear is effectively self-cleaning: skin cells slowly migrate outwards from the eardrum, carrying earwax with them until it falls away naturally.
Hairy ears, wearing a hearing aid or earbuds, and too much poking around with cotton buds can all cause earwax to get trapped.
