After using this mask for over a month, it has become one of those products that I really don't want to live without! It's a large tub and I use a fair amount, but I didn't find I went through it too quickly! I was using it about 2 - 3 times per week and a couple of times I left it on for 20 minutes for the ULTIMATE hair repair treatment and my hair felt great! Not only did it feel stronger, but it felt way more protected and less damaged after heat styling my hair (which I usually just avoid because my hair is so bleached already) HIGHLY RECOMMEND!
