How to stop mould on bathroom ceiling

We get mould on the bathroom ceiling despite having an extractor fan. It comes back every few months so what's going on? What can I do to finally get rid of it?

"Hi you can treat the mold then once dry paint only using an anti mold paint, the extractor possibly won't be enough and you need more air flow so fit trickle vents on window or leave window open on the slight lock so there is constant air flow also leave bathroom door open after bath or shower. Never shut windows even in cold weather. All down to right condition for the mold with moisture and humidity."

"Mould is usually caused from moisture on the ceiling which cannot evaporate or dry because of poor ventilation.

Do you have a window in your bathroom also or purely extractor??

If extractor is only option then probably look into the extractor either inadequately placed in the bathroom or if it is then maybe an extractor upgrade of check the ducting from your extractor.

These are a few factors to consider. Hope this helps?"

"Make sure that the windows are open Daly to let the Air circulate and you can also get a dehumidifier"
