Review on Herbatint Permanent Haircolor Gel, 1N 🖤 Black: Rich & Long-lasting Results, 4.56 Ounce by Sheila Vaughn

I've been buying this bottle for many years but my last bottle seemed different from previous purchases. The biggest difference I noticed was that the color changed after a long time. It usually takes me about 10 minutes to see a color change and 15 minutes for it to be fully visible. Also, I had an odd taste in my throat (I had to go outside for some cool air and that feeling still hasn't gone away), and for the first time ever, my eyes burned a bit from the fumes(?). (Keep away from eyes, only fumes). I had to air the bathroom. I can't remember this happening before. Revain, please ensure this is from the original manufacturer. I may need to find another *natural* hair color.
