How long do you have to wait for hair removal cream to work?

Could you elaborate on the expected waiting time for hair removal cream to be effective? I'm curious about the average duration it takes for such creams to deliver the desired results. Is it a matter of minutes, hours, or does it vary depending on the type of cream and the individual's skin type? Additionally, are there any indicators that suggest the cream is starting to work, or does one need to simply wait for the recommended time and then assess the outcome? Your insights into this process would be greatly appreciated.
