For salon professionals and experienced at-home perm users after a soft wave or loose curl rather than a tight ringlet. Purple sits at the jumbo (largest-diameter) end of BaByliss Pro's cold wave rod range — grouped with beige and orange in that size — so it suits longer hair where a body wave is the goal. It's a cold-process tool: no heat is involved, and it only produces a curl when used with a separate chemical waving lotion.

What sets this size apart within BaByliss's cold wave rod line is diameter: purple is grouped with beige and orange as the jumbo option, built specifically for a soft body-wave result rather than the tighter curl smaller rods create. The non-slip band-and-button closure and wide center slot for lotion saturation are shared across the whole line, so the color mainly signals which curl size you're picking up.

Detangle hair and section it into clean partings sized to the rod. Wind each section around the rod, working from the ends toward the scalp, keeping tension even so the wave forms consistently, then secure with the rod's band and button. Continue until the area is fully wound. Apply cold waving/perm lotion following that product's own directions and let it process for the stated time — the rod itself is never heated. Rinse and neutralize with the rods still in place per the perm system's instructions, then rinse again before unwinding.

• Jumbo diameter creates a soft, loose wave rather than a tight curl
• Same non-slip injection design as the rest of the line, with a band and button to hold sections through processing
• Wide slot lets cold-wave lotion saturate hair evenly
• Fewer rods typically needed per head than smaller sizes, which can speed up wrapping
• Not suited to anyone wanting tight curls — pink or gray sizes do that instead
• Still requires a separately-purchased cold waving/perm lotion and full perm process
• Larger rods can be trickier to keep flat against the head during wrapping
