I haven't shampooed my hair in two and a half weeks.
It's completely true. I took the "no poo challenge" and it works! At first my hair had to adjust and it was oily but I stuck it out and WOW. My hair has never been shinier. I do use white vinegar instead of apple cider and just because I like the smell.. I drop a couple of sweet orange essential oil into the vinegar+water rinse.
