Abba makes plant derived hair care products that are only sold in salons. It is one of the very, very few salon products that is not only sulfate free, phthalate free, and paraben free, but also 100% vegan (no animal testing and no animal products). To get an idea of how rare that is, google “cruelty free hair salon products” and see what you get. It’s pretty much only Paul Mitchel, Giovanni, and Abba.
The only Abba hair care product I’ve tried is the Gentle Conditioner. And it’s probably the only one I will try because I love it so much. I bought it as a set with the Gentle Shampoo, which was okay but didn’t give me a squeaky clean feeling (in other words, it seemed to weigh my hair down, which is a common failing of sulfate-free shampoos in my opinion). But the conditioner is perfect for me. It’s very light and seems to absorb into my hair immediately. I use it every day as a leave-in conditioner after I get out of the shower as the last step in my morning hair regime.
