I have quite wavy to curly hair and spend hours trying to keep it under control. I asked in one of the salons for advise on hair products and was recommended this one. It was a lot more expensive than standard shampoo but I have to say it is more than worth the price. My hair looks and feels in great condition. Previously I would straighten my hair every morning and it was a mammoth task. After using L'Anza smooth shampoo and conditioner I can get away without having to use straighteners every day, something I would never have thought possible!
