I live in the south where in the summer time we are exposed to a lot of humidity. To be honest, I am not even complaining about the humidity though because my hair becomes so full and curly that I feel like I was made, at least my hair was, for this weather. However, in the cold months I can do nothing with my hair. If I switched to a kevin murphy angel wash would that help give my think and damaged hair more life? I know that it is for thin hair, but in the cold weather I have no body to it.
