Can you loosen your curl patten by using heat? Yes it is possible, I had my natural hair blow- dry and silk press and after I washed it the pattern was much curlier. Some people like it and some people hate, it depends on the person. As for me, I don’t mind this and don’t find it to be a problem. Some people love using heat and others don’t. But just always know that yes heat will and can loosen your curl pattern, it is up to you if you choose to use it or not.
