So recently, (the last 2-3 times of coloring my hair black) i have had allergic reactions, getting worse each time i colored it. I read about EcoColors and how it is good for those people with hair dye allergies. I have a concern though with the size of the bottle of color. How much does the 4 oz. typically cover? The last stuff i used had 8 oz per bottle & i had to use 2 bottles for my whole head because i have long, thick hair. That would be 4 bottles of this color resulting in $100, give or take a couple bucks. That's kind of a lot for hair coloring to do at home. Just wondering how much one bottle usually covers??? Would like to only have to buy one as it is pretty spendy. Thanks
