Billy Jealousy offers two shampoo and conditioner sets. Our signature Fuzzy Logic Strengthening Shampoo and Cashmere Coat Strengthening Conditioner are formulated specifically to slow hair loss. These products contain ingredients that block DHT, a byproduct of testosterone, from attaching to and weakening the hair follicles. Fuzzy Logic and Cashmere Coat both contain peppermint oil and other natural extracts that help to increase the circulation of blood and oxygen to the scalp which can help to stimulate healthy growth. This combination is best for men with all hair types, and especially those with fine or thinning hair. Monsoon Mist Tea Tree Shampoo and Typhoon Tango Tea Tree Conditioner are formulated with tea tree oil to moisturize and soothe the scalp, reducing itchiness and irritation. Tea tree oil is highly effective for clearing out clogged hair follicles, helping to eliminate flakes and dandruff from excess product buildup and oil. The powerful tea tree oil, while highly beneficial to the hair and hair follicles, can sometimes be harsh on skin and hands, so our specialty blend dilutes the tea tree oil with peppermint oil for a nourishing, hydrating, and refreshing feeling every time you shower. This combination is recommended for men with all hair types, and especially those with dry, itchy scalp or dandruff.
