I’ve tested many brands, and the ones that work best are those with ingredients like argan oil, keratin, or aloe vera to soothe the scalp and add shine. Avoid heavy silicones that can build up over time, as they may make straightening harder. If you’re using a heat styling tool regularly, a clarifying shampoo once a month can help remove product buildup. Stick to a routine that keeps your hair hydrated and protected from further damage.
