On the surface, Madi's poem is a casual, almost chatty look at hair: how strange it is that it grows thickly from only your head, how many things you can do to it, and how it gets damaged when you do too much. But the repeated line "I'm sure some people are like that too" keeps nudging you to read it as something more. The poem seems to be comparing hair to people, and the idea of cutting away the damaged parts starts to sound like cutting people out of your life.
The speaker's tone starts light and playful ("really cool") and slowly turns more pointed. By the last stanza, the line about people cutting hair "because they're ugly" and wanting the healthy part to survive carries a sharper edge. The repeated refrain feels like a shrug, but also a quiet judgment. The mood is casual on top and a little uneasy underneath, leaving you to decide what the speaker really thinks.
