大量掉发Heavy shedding
Heavy shedding大量掉发一洗头就一把,枕头和地板上也是。多数情况不是「头发本身」的问题——是头皮长期出油、角质和造型品堆在毛囊口,发根扎不稳。A handful in the shower, more on the pillow. Usually it isn’t the hair — it’s oil, dead skin and styling residue building up around the follicle openings so the root never anchors properly.
一天掉一百根上下是正常的,换季还会更多。要看的是「有没有比三个月前明显多」,不是数根数。Losing around a hundred a day is normal, and more when the season turns. What matters is whether it is clearly more than three months ago — not the count itself.
