Triangle of Hair Missing in Middle of the Hairline

hi,what is it called when the hairline is kind of an inverse widow’s peak – when there’s a little spot (maybe triangle-ish) of hair missing right at the top?

i’ve been googling to no avail and it is rather worrying me as i am only 16 years of age ,male. i have very thin hair aswell but only because i have straightened it for the past 2 years so i am not sure as if that has somthing to do with it

Assuming that you have not damaged the hair from straightening it, some people have irregularities in the frontal hairline that is normal and genetic. These irregularities can be fixed with a transplant into them to reshape the hairline. At 16 years old, I am not sure that you are a candidate, but you should be examined by an expert if this is something that you want to do.
