Pete & Pedro Clean is our signature deep cleansing shampoo and hands down the best men’s shampoo on the market. Clean contains loads of invigorating peppermint and tea tree oil to deliver big time cleanliness via a rich lather. Just a small squeeze should be more than enough to keep hair fresh, vibrant, healthy and clean like never before. The energizing peppermint scent will awaken the senses and let you know the shampoo is working hard. Tea tree oil is well-known to help remove oily build up and dead skin, and is a natural anti-fungal and antibacterial agent that works hard to rid microorganisms that thrive on the scalp and contribute to dandruff/flaking skin. Paraben-free.
