I have naturally curly hair, that was extremely dry with little volume as of July 2014. I decided to give these vitamins a try, and am so happy I did! As of January 2015, my hair is so much healthier, fuller, and longer. My curls are even curlier:) I had my hair trimmed twice in the last 6 months, just to shape it up and keep it even. If I didn’t have those trims, my hair would be 3 inches longer than it is now! Just bought another 6 month supply!!
