For Color-Treated Hair

Growing up, I never paid attention to the shampoo I used. (Literally, I'd use anything as long as it smelled good.) That changed the first time I dyed my hair a couple years ago. I never realized how harsh and terrible brand-I-shall-not-name was until it stripped all the color out of my hair. That's when my hair colorist (and my mom!) recommended something sulfate-free, and I fell in love with this L'Oréal Ever Pure shampoo.
It's super cheap, I can easily pick it up at the drugstore whenever I run out, and it comes in a variety of formulations depending on your hair type. (Same goes for the conditioner.) I got my hair colored again while using the shampoo and the dye actually lasted.
