Lavender - 100% natural Lavender essential oil is known to help promote relaxation, calming, & a good night's sleep. Step-up your shower with an aromatherapy shower steamer. A Shower Bomb releases essential oils into the air to mix with the steam from the shower & create a spa-like environment for your enjoyment. How to Use: We recommend cutting your Aller-Ease Shower Bomb into 4 pieces as you should get 4 great aromatherapy showers per shower bomb! Set your piece of shower bomb in a dry area of your shower such as a ledge or shelf. Sprinkle some water on it to activate it (but try not to let it get too wet from the shower itself... the drier it stays, the longer it lasts!)
