Query: So smooth and shiny

I first got a sample of this which i am glad they offer, then i tried it and fell in love. This product truly does as it says, however i feel as though the results are only seen when you use it. Since it's a 1-2 X a week treatment when I don't use it that one time, my hair is back to the same dryness it was. However, I gave it 4 stars because I am just so happy with the results it gives me for that time that i leave my hair styled (which is about 2-3 days) not bad considering this is a product that can be used 1-2 times a week. BTW i have frizzy thick curly hair. Hope this helps!
