Good product, makes my hair REALLY soft and healthy-looking. However the bottle is WAY too small for the price. Not sure if I would purchase again because of the size but just on effectiveness, I would maybe give it another shot

Saving grace

Demanded my hair with sun in spray, got my hair dyed to fix the color. My hair was dry, tangly, and demanded. This completely saved me. After just a couple uses my hair my soft and new.
