Your formula is composed to order and made to last a considered rhythm. Every formula you build is saved with its Formule N°, so reordering is simply a matter of returning to it.
Automatic replenishment is coming soon. You will be able to have your formula remade and delivered monthly, or every two, three or six months, so it arrives just as you reach the end of the jar. Until then, reorder by hand whenever you are ready.
