I Have Blonde Hair and I’ve Noticed Black, Dense, Curly Hairs Growing Randomly

I am late 20’s have begun to get thin in my front hairline and where my natural hair swirl is on my vertex and I’ve accepted that’s just within my family. But I am trying to keep track of how much is changing and I have noticed that ( I have dirty blonde hair) I am getting hairs turning almost black growing in random spots. Just single hairs and sometimes in groups of 3, one will be this black curly one. And those hairs have a seemingly denser feeling and posses a curl to them that does not compare to the rest of my natural hair texture. Any ideas what this is and what’s causing it?

If you have dirty blond hair, then dark colored hair is likely the norm. Some people just have random hairs that grow with different characteristics. It just may be the norm. Otherwise, I have seen some patients go through hair color change in their 20’s and 30’s as they go from lighter to darker or vice versa.

I do not think it has any relationship with respect to hair loss.
