Hair fallout

ℬ𝓇𝒾𝓉𝓉𝒶𝓃𝓎

Random question and picture for attention.

So i have naturally wavy/curly long hair.

I always straighten it because for one im not the biggest fan of my natural hair, but also because when its natural my hair will come out more than when it is straightened. I dont understand why? I can run my fingers thru it and bam five hairs come out. But when its straight it dosent happen? Lol Anyone have any idea why it may?
