Invigorate your hair and your senses with Bumble and bumble Tonic Shampoo. This cult classic infuses all of the therapeutic qualities of Tea Tree Oil into a mild, aromatic shampoo. A daily favorite (even among men!), Tonic Shampoo gently cleanses hair while it tones the scalp. Essential oils include Tea Tree Oil for natural antiseptic properties; Peppermint Extract to regulate oil production; Rosemary Extract for stimulation; and Lemongrass Extract for added body and shine. We recommend this potent, stimulating scalp smoother for most hair types unless your hair is extremely dry or very chemically treated. Wake up your hair with this invigorating shampoo from Bumble and bumble.
