Hi, I wonder if you could help me, I am 28 years old and I have always had slight thinning in the temple areas of my scalp. I have always been able to hide this with a fringe etc but since I have been using hair straightners I can’t put my hair up in a pony tail as you can see the thinning more and I have started to receed. Could this be because of using straightners that it has become worse or could there be an underlying cause. Both my parents have full head of hair and hair thinning doesn’t run in the family.
Without seeing a photo of you it is tough to tell, but given your age and the circumstances you describe, I suspect you have some degree of traction alopecia, which is hair loss caused by pulling at the root. This is commonly caused by tight braiding, ponytails, etc., and as you can imagine it is more common in women. Any mechanism that pulls excessively at the hair may cause this (even clip-on or glue-in hair pieces) and over time if the hair continues to be pulled, it can become permanent. You also mentioned that you have begun straightening your hair. Sometimes, the chemicals in hair treatments can damage the hair and cause loss. In addition to that, though, when you straightened your hair, the problem worsened since straight hair covers less area than curly or wavy hair does. Pulling your hair back into a ponytail not only pulls at the hair at the temples, it would also expose the areas that already have loss making it look worse. Without examining you I cannot tell how much of your hair loss is due to chemicals or to traction, but loss at the temples is a hallmark of traction alopecia all by itself. Neither of these is genetic by the way.
What I would suggest is that you stop using any styling that would cause excessive pulling (i.e. traction) on your hair and also stop using straighteners for at least 6 months to give the hair a chance to grow back. If your hair does not grow back in a year, you may be a candidate for hair transplant in those areas.
