This shampoo is no joke! Laughter is Best Shampoo gently cleans damaged, dry, or colour treated hair while it strengthens and adds shine. This moisturising lightweight formula contains keratin and silk proteins without all the nasties. Not only does it help extend the life of a blow dry, it features UV blockers to shield your hair from those toxic rays. Fake foaming agents are out - Sorry, no bubbly beards in our showers. HOW TO USE: Massage in product with lots of water, rinse, and repeat. We suggest using with 'Winter Is Coming' Conditioner 2-3 times per week.
