If you have naturally curly hair you know that if you blow dry, flat iron it regularly it will eventually end up straight or at least straighter than it was.
I personally have naturally curly hair and after leaving out the top of my hair for a few weeks while I was wearing a U part wig. I was left with bone straight hair ...and I mean bone straight...no going back...it's a permanent affair..:..Just have to let it grow out..oh well..:-(.
Same applies to your MyMy hair. If you want to alter the curl pattern in terms of loosening the curl, without using chemicals, simply blow dry and flat iron on high for a couple of weeks. Check the curl pattern, and when you are happy stop applying the heat...That's it...simple Huh?
