Grooming
Eyebrow Slits
Purely a style choice with no physiological claim attached — reversible in weeks, unless a razor scars the follicles, in which case it is not.
Also called: brow slits · eyebrow cuts · brow slit trend
Verdict — mixed
Real in part — the claim outruns what it actually does.
Evidence grade D
Nobody has demonstrated this works. Note that this grades the evidence, not the danger — read the verdict for that.
Mechanism
Shaving a gap in the brow removes hair at skin level; the follicles are intact and regrow on the normal brow cycle of roughly four to six weeks.

The full read
Included because it comes up constantly, not because it is a method. There is no attractiveness claim to grade — brow slits are a fashion signal, and how they read depends entirely on context and on the rest of the face. Two practical notes. Deep or repeated cutting with a blade can scar the follicle and produce a permanent gap, which is the one way this becomes irreversible. And brow shape genuinely does affect perceived expression and masculinity, so if the underlying goal is a better brow, `eyebrow-grooming` covers the version with an actual effect behind it.
