Great Conditioner with Subscreen!!

I never buy anything but GK hair care products. I have curly hair (permed) and it can dry out so easily. I use GK shampoo & conditioner with the sunscreen. It makes my curls so shiny and the sunscreen really helps especially in the summertime! My hair is well conditioned and soft! It really protects my ends as well. I get a lot of compliments on my hair from total strangers. When they ask me what I use I tell them GK all the way!!

Wonderful product -- Didn't ship well!

I love this conditioner so that's the reason for the 4 stars -- best ever for me! I can't give 5 stars...the problem was how it shipped. When I received it, the conditioner was all over the inside protective bag. So, now my option is to try to scrape it all back into the bottle or return it unused. But I'm almost out and who's to say a replacement bottle won't get to me in the same messy condition.
