Is it true that having your hair pulled makes your hairline recede? TMI alert: My ex had this bad habit of pinning down my hair during sex. I always had to yell at him to make him stop, but he never seemed to learn. I was always worried that it would cause my hairline to move back, though I doubt is has (we didn't have much of a sex life). Also, does wearing hair pulled back a lot create a larger forehead? I've heard it only does if it's pulled tightly. I don't think I have a large forehead but it's larger than it used to be - I attribute that to wearing my hair back more often in the past several years.
