Cutting Hair for Headache Relief?

My 15-year-old niece who has chronic daily headache asked me if cutting my hair, which was to my mid-back, into a pixie cut reduced my head pain. Although I don’t remember noticing a correlation, I’m hoping you may have some experience with this. She said it always feels like her hair is pulling on her scalp and that she gets a horrendous headache whenever she straightens her hair. Any idea if cutting her hair may help relieve her head pain?
