Here's why:
* "Relaxed" in the hair world usually refers to a chemical process used to straighten naturally curly or coily hair. This process alters the hair's structure permanently. So, if you've already relaxed your hair, it's already straight (or straighter than it was before).
* If you mean "relaxed" as in "letting your hair air dry without styling," then no, that won't straighten your hair. Air drying will usually leave your hair with its natural texture.
To clarify, can you tell me more about what you're asking? For example:
* Are you talking about relaxing your hair chemically?
* Or are you wondering if you can straighten your hair without heat or chemicals?
Once I understand your question better, I can give you a more accurate answer!
