Customer Review of the Day: The End Serum. “The End Serum Works!!! I have curly, course, unruly hair! But with the Maxiglide, Beyond Straightning Serum, and The End Serum, I now have long bone straight hair that last all week!! The End seals and locks out humidity!! And I live in Florida with high humidity!   I love The End Silicone Shine Enhancer Serum! I feel beautiful again!!!”
