Moon Shine Magnesium Shampoo helps to fight annoying seasonal headaches and recurring migraines. Magnesium counteracts with calcium, improving circulation which in turn will also aid in relieving chronic head aches and making sure calcium gets to your bones where it’s needed, rather than clogging up on the surface of your scalp. Use Moonshine just like regular shampoo. Work up to a lather and rinse. Make sure you allow the shampoo to reach your scalp. Rinse and enjoy!
