I searched around and didn't find a recent thread addressing this. Just sharing my experience!
Recently moved to Europe and my hair quickly digressed into an unmanageable mess. We have really hard water here. And I haven't found a stylist yet, so it just keeps growing, and the problem gets worse. I was combing my hair with a huge glob of conditioner because it was knotty before, during and after the shower. I didn't have to do that before our move.
After @ 4 mths I had had enough and searched around for a solution.
I am using a shampoo from The Body Shop (no SLS, silicones, etc) and a vinegar rinse. I use an empty shampoo bottle, put in @ 2 cm of vinegar (using white now, will switch to apple when it is gone), fill it up with water at the end of my shower, pour over my head, wait @ 1 min, rinse lightly with cool water. Perfect hair! The most amazing thing is my hair DRIES QUICKER! I am not sure why, but it does! Bonus! Just shampoo and vinegar. I stopped with the conditioner all together after about 2 weeks.
