Revlon appears three times here: the One-Step RVDR5222 in the version supplied with a
sectioning comb, the Perfect Heat hot air kit, and a two-inch straightener that
is the cheapest item in that family.
What we found writing the reviews
The oval head is the product. A flat face against the length and rounded
ends at the root means one stroke smooths and lifts at the same time. A round
barrel needs two strokes; the AS8811 / RVDR5222 comparison sets the two shapes side by side.
The sectioning comb is what distinguishes this version from the plain
One-Step, and sectioning is what makes a hot air brush usable on long hair at
all.
Revlon states the intended hair length: mid-length to long. On a tool whose shape decides what it can reach,
that is a useful line.
And then the listing stops. No number of heat settings and no weight. The
wattage is published on the Perfect Heat kit — 1,200 W — and on neither of the
other two. The two percentage claims it does make — 30% less frizz, 36% less
breakage — carry no stated baseline, so they are reported on our page as the
manufacturer’s own figures and nothing more.
Two of the three are listed on amazon.com — the Perfect Heat kit and the
straightener, at about $30 and $14. The One-Step in this version is not, and its
page says so.
The brushes are compared in the hot air brushes category and the
hot air brush guide.
