Found a way to stop my color from washing out so fast
I was so tired of my vivid reds fading after like 2 weeks no matter what conditioner I used. Tried that whole cold water rinse thing and it barely helped. Then a stylist in Denver told me to rinse with diluted apple cider vinegar after my shower. I did 1 tablespoon per cup of water and just let it sit for a minute before my normal conditioner. Been 3 weeks now and my color is still bright. Has anyone else tried this or got another weird trick that actually works?
Tried vinegar on my hair once and my whole apartment smelled like a salad bar for a week. My color held up decent though, so I guess that's the tradeoff. Now I just accept that my purple is gonna look washed out by week three and save myself the pickle juice smell.
I mix a little vinegar into my cold water rinse and only leave it for like 30 seconds then rinse again with plain water. The smell fades way faster that way and I still get the color boost.
