All hair is prone to pollution & attack by "free radicals" & other things with scary names. We use Peppermint Leaf & Sorrel leaf extracts believed to expel the build up of toxins & together creating a mildly astringent action to benefit the scalp. Using Naked Detox once in a while can clean away chemical build-up, leaving hair healthy & refreshed (without the need for suction tubes in funny places & 32 glasses of water a day). For best results, always follow up with Naked Detox Conditioner.
