I agree with the previous comment, it is because the hair is longer and it seems that it falls more, but it is normal that it falls in the day, my mom always tells me that I have my bed full of my hair because when I am there I touch my hair all the time or anywhere, and maybe that makes my hair sensitive, maybe it happens with you ... but it's irresistible not wanting to touch your hair, at least for me it's like a nervous contraction, I think XD

If your hair seems thinner from the root, and you see that in the mirror or in photos you see a part of clearer hair, then be afraid, it would mean that you start to be bald, that I saw on a
page xdd, so be alert, although I think that hormonal blockers and estrogen will keep you safe from hair loss: 3
