I have only tried the Ion protein treatment pack from Sally's and I only left it on for a couple minutes since it says to leave it on for only 2 - 3 minutes, or 3 - 5 minutes for damaged hair. Would you recommend leaving that on for longer? Maybe just leaving it on for a couple minutes isn't good enough for me. But I'm not sure if it's alright to leave this certain protein treatment on for longer than a couple minutes or not.
Also, I bought the tresemme naturals radiant volume conditioner and the trader joe's tea tree tingle conditioner to try out. I really like them both. The trader joe's tea tree tingle works well as a co-wash and a rinse out for me. So thanks for suggesting these everyone!
