Is cold water good for your hair???

I have been washing my hair in cold water with conditioner...it seems to really help my hair. I have noticed that the ends of my hair aren't as "crusty" and feels alot smoother...before i started this cold water "method" i washed my hair in scalding hot water and my hair was very dry at the ends...should i continue this? Advise appreciated. (I'm trying very hard to grow long hair...i don't want my hair to looked screwed up)
