After the first use, I could see a difference in my hair. I apply it to my ends after styling and it gives a beautiful healthy shine. It minimizes the look of dead ends and seems to help the hair become stronger with continued use. Applied to staright hair at the ends the product reduces frizz and makes it appear even straighter and longer, applied to curly hair, it helps do smooth/ moisturize / and defrizz the curl. Great product! Recieved earlier than expected! Thank you!
