Sable Cove Hydrience was actually my very first experience with coloring my hair, much less by myself, and it made the process a lot less scary and intimidating than I'd expected it to be. It is remarkably easy to prepare and use, and a single bottle covered me--which is really impressive, because I've got a lot of hair. The color itself is a rich, intense, dark brown, with good and natural-looking color depth, and not only was it not damaging to my hair, but it left it in better condition than it had been to start! Wear length was also very good; it didn't fade for at least two months, and even then, it was gradual and subtle. (Your experience may vary, of course, depending on what color you started with.) It's not as harsh on your hair or as big a commitment as many of the level 3/permanent formulas, so I'd recommend it in a heartbeat for a person who isn't sure they're ready to commit to a certain color yet, or who's coloring for the first time, or even for people with more fragile and damage-prone hair. Great product!
