In terms of how long until you need to refill, this will be individual depending on how often you use the hand wash, how many of you there are, and whether you are in a hard or soft water area.
In terms of how long with the bottle itself last, please head to our Body Wash page here for the answer. All cases and refills across the Body Wash, Hand Wash, and Haircare range are the same, so they can be used interchangeably. This means the answers are the same, so we've kept them all in one place, rather than get repetitive!🔁
