Is it okay to just use mousse as a product for twist outs all the time. Is thats bad for my hair
It's only bad if the mousse has drying alcohols in it, which I believe most do. Check the ingredients.
Check the ingredients. I would switch it up and try cream gels, of give your hair a break form time to time and just wear it in it natural curl pattern. Also, layering is key. You want to layer a leave in conditioner under the mousse.
