When can you get your hair wet after a relaxer is put in?

I recently put in a relaxer and yeahWhen can you get your hair wet after a relaxer is put in?
Even the next day is ok, the chemicals will have already worked or not! so it's all good! just bear in mind that relaxers tend to dry your hair out so get some products to add as much moisture and healthy oils as possible whilst still retaining movement and shine!
