Would it be better to check hair thickness first rather than the amount of hair falling out?

When I take recent photos, the top of my head seems thinner than before, so I am looking into hair loss.

However, there is also talk that it is difficult to judge based solely on the number of hairs falling out.
I am wondering if I should also look at changes such as hair thickness or part width.

Those who have undergone a hair loss test
I would like to hear about your experience regarding what factors led you to decide on hospital treatment.

저도 탈모인지 아닌지 고민 될 때 모발 양 뿐만 아니라 모발이 잘 끊어지거나 얇아지지 않는지도 같이 볼 것 같아요 . 계속 비어 보인다면 혼자 판단하기보다 두피 진료 한번 받아보는 게 마음도 편할 것 같아요!

저도 탈모는 단순히 빠지는 개수만 보는 게 아니라 모발 굵기나 가르마, 정수리 변화도 같이 보는 게 중요하다고 들었어요. 예전 사진과 비교했을 때 눈에 띄게 달라졌다면 피부과에서 한번 확인해보는 게 좋을 것 같아요
