I have really long, fine hair that gets extra dry in the cold weather, so it's super prone to split ends. I also color it from brown to blonde, which doesn't help the split ends I get, but never the less I still do it because I take really good care of my hair.
Anyhow, I got this stuff and have been using it for a week, and I love it! I use it over my regular leave-in (I like the Olive Oil products by designline) on days I shower, and then by itself on 2nd day hair. Works great, I really wasn't expecting this type of results!
The first day I used it and wasn't amazed at first. I put it on wet hair and let it air dry like normal, and at first before my hair all the way dried it felt like it was weighing it down. But when it finally completely dried, I had gorgeous, smooth, soft hair that looked better than it did the day before! On day 2 you could really tell the split ends weren't coming apart anymore, and on day 3 my hair was actually retaining moisture- even after I straightened it! It was crazy! I love the smell, too, it smells like pine kind of. They use Nexxus stuff on my hair whenever I get it colored at Regis and I just LOVE the smell (the shampoo/conditioner are just too heavy for my fine hair or I'd use that, too).
I would definitely recommend this product if you have long hair, colored hair, are prone to split ends, or all of the above. Next I really want to try the night-treatment version of this product.
