/cgl/ - Cosplay & EGL

I don't know where to ask it so it maybe the wrong thread. I let my bang grow for a long time and I noticed that the bang part of my hair is darker than the rest of my whole head. I used to bleach my bangs to the root for fashion color every other few month for 6 year and only stoped last year so it's my first virgin fresh regrowth there. I have dark hair since I was a kid and they only got darker over time really slowly.
I didn't noticed anybody else having this IRL and I scared it got like this because of bleach ( even thought it didn't got thinner or more sparse), Do it happend to anyone else ? Should I be worried ?
pic related is my hair slightly edited to look like it is irl, bangs are to the right, it was freshly washed and my camera is a potato
