The Queen's Crown Shampoo, formulated exclusively for hair extensions.
 
My Shampoo has a strong cleanser because when you have extensions you should only be washing once or twice a week.  Make sure you wash twice and a very detailed rinse, theres no need to wash the extensions the shampoo will run over the hair when you rinse.  The shampoo also contains a water soluble silicone that is beneficial for your extensions and keeping them silky soft. Also,  made with Marula and Argan oil.
