This shampoo and conditioner system has really given me much healthier hair. I live where the water is very very hard and my hair was so tangled from the splits. Once I started using this, it pretty much fixed it within a week. I love the way it smells and I find that my hair is staying cleaner for longer, so I don't have to wash it as frequently. Effectiveness The was a minor improvement after the first wash, but after about a week of usage, my ends were much less dull and were not breaking every time I put my hair in a bun. Using a straightener is now an option for me too! I do think I should note that I am basically conditioning twice to get these results. I use the shampoo, then a treseme conditioner and then the split end treatment after that. So that makes it a little more work and slightly more expensive, but the results, for me at least, are worth it! Scent It smells a little bit like dryer sheets, which is a little bit strange for a shower product but makes you smell super fresh and clean! My husband really likes the way my hair smells when I use this too.
