Garnier Good 5.0 Coffee Roast Brown Permanent Hair Colour

As a retired hairdresser. I'm always looking for a great supermarket or chemist hair color I can find. I've tried nearly all of them, & this time I bought the Garnier "Good", It has given me 100% coverage, as opposed to many of the others that might give me only 60% to 80% coverage of my greys. It's ammonia-free which is great. Instead, it has Ethanolamine which raises the pH and open the outer hair layer so color can enter in a much gentler way, ammonia blasts open that hair cuticle and can be very drying on your hair. It's packaged brilliantly as well, and it doesn't smell. I recommend this as a hairdresser.
