The air in the climate where I live is so dry in winter. I have been pleased with the results of frequent, almost obsessive skin moisturizing. I decided to try the same approach with my hair. I have always been amazed by the womens' hair featured in hair ads. While at one time in my life I had opportunities to work as a hair model, daily medication and frequent swimming have left my hair one of my least appealting features. A natural redhead, I recently began wearing styled blond wigs in public. At home, I do go "au naturel" with my hair and I have noticed a remarkable improvement -shine!-after daily application of this sulfate-free product. Please note I apply it almost daily and leave it on for about an hour, my hair wrapped in a towel. I rather like the packaging, because the container is truly reusable. Sometimes I remove beauty product from the tubes and store it in the pots because they stack and travel well.
