Hi folks. Looking to see if you would do the nourishing lotion after the tint or before ? Also I'm using the sachets and was wondering with the nourishing lotion if it can also be used to help nourish the lashes in the days after the tint im finding I'm getting loads left in the sachets once used on a client and wasn't sure it it could also b used by the client at home to help keep the lashes in good condition?
