发质硬英语怎么说

"发质硬" (fā zhì yìng) 指的是头发非常硬、粗糙或僵硬，通常会导致发型不易打理。

这个表达方式可能来自于中文中对头发状态的描述。在英文中，通常会用 "coarse" 或 "rough" 来形容头发硬质。例如：

My hair is so coarse that it's difficult to style. (我的头发很硬，很难打理。)
Her hair is rough and prone to tangles. (她的头发很粗糙，容易打结。)

也可以用 "stiff" 来形容头发僵硬。例如：

His hair is always so stiff that it sticks up in every direction. (他的头发总是很僵硬，向各个方向都会竖起来。)
She used so much hair gel that her hair became stiff and unruly. (她用了太多发胶，导致她的头发变得僵硬而不好打理。)
