9.2 Perm Wrapping Techniques, Base Placement & End Papers

Key Takeaways

  • Subsection width should equal the rod diameter; too wide or too narrow distorts the curl
  • Base placement (on-base/half-base/off-base) controls scalp-side curl tightness: on-base is tightest, off-base is softest
  • Base direction (forward/back) controls curl flow and movement, not tightness
  • End papers protect the ends and give a smooth wrap; any crease in the paper causes a fishhook
  • Croquignole wraps horizontally from ends to scalp; spiral wraps vertically/diagonally for long hair

9.2 Perm Wrapping Techniques, Base Placement & End Papers

Quick Answer: A perm is wrapped in clean, even subsections — usually a 9-block or bricklay pattern — with subsection width equal to the rod diameter. Base placement (the angle of the rod relative to the scalp: half-base, base-base, off-base, on-base) controls how tight the curl sits at the scalp, with on-base the tightest/most tension and off-base the softest. End papers protect the hair ends and must be folded flat — creases cause fishhooks.

Sectioning the Hair

The wrap begins with a sectioning pattern that distributes rods evenly and keeps tension consistent. Two common patterns:

  • 9-block pattern: the head is divided into nine panels (top, sides, crown, nape sections) so each panel carries a consistent rod count and direction. Easy to learn, predictable, and good for standard bobs and medium-length hair.
  • Bricklay pattern: subsections in each panel are offset like bricks in a wall, so no two rods sit directly above or below each other. This staggers the curl pattern and avoids visible "lines" — ideal for softer, more natural-looking perms and longer hair.

Each subsection width equals the rod diameter: too wide and the hair won't wrap cleanly; too narrow and the rod is underloaded, producing a tighter-than-expected curl. The length of the subsection should not exceed the rod's wrap capacity, generally 2–2.5 times the rod circumference.

Base Placement: Angle of the Rod to the Scalp

Base placement is the angle at which the rod sits relative to the scalp once wrapped. It directly controls scalp-side curl tightness and tension:

Base PlacementRod PositionTensionCurl at ScalpUse
On-baseRod sits fully on the baseHighestTightest, most curlFirm curl, resistant hair — but most stress on hair/scalp
Half-baseRod half off the baseMediumMedium curlMost common — balance of curl and safety
Off-baseRod fully off the base, pointing awayLowestSoftest, least curlDelicate, fragile, or over-porous hair
Base-base (1.5 base)Rod ~1.5 diameters off baseMedium-lowSoft-medium curlClients sensitive to scalp tension

On-base gives the most curl but also the most stress; off-base is the safest for delicate hair. Half-base is the default for most services.

Base Direction: Forward vs Back

Base direction is the angle at which the hair is pulled before winding — typically forward (toward the face) or back (toward the nape/crown). Base direction controls the movement and flow of the curl rather than its tightness. Pulling hair forward at the front hairline creates a face-framing sweep; pulling back at the nape keeps the curl pattern lying flat against the head.

End Papers

End papers (also called wrapping papers) are thin absorbent sheets wrapped over the hair ends before the rod is wound. Their jobs:

  • Protect the ends from the direct chemical and mechanical stress of the rod.
  • Give a smooth wrap so the ends don't bunch, twist, or fishhook.
  • Absorb excess lotion and distribute it evenly along the strand.

Correct end-paper use: fold the paper over the ends so they lie flat and straight, then wind the rod up the strand. Any fold or crease left in the paper imprints into the hair and produces a fishhook — a sharp bend at the end of the curl that won't relax. Papers must be trimmed or replaced if they overlap awkwardly.

Rod Sizes and Wrap Patterns

Rod diameter sets the curl diameter. Smaller rods produce tight, springy curls; larger rods produce loose, wave-like curls.

Rod Size (diameter)Curl ResultTypical Use
Small (~9–11 mm / blue)Tight, firm curlShort hair, spiral ends
Medium (~13–16 mm / yellow, white)Medium curlMost standard bobs
Large (~19–22 mm / pink, orange)Soft curl / waveLonger hair, body wave
Jumbo (~25+ mm)Loose wave / bodyVery long hair, volume only

Two wrap patterns dominate:

  • Croquignole — the hair is wound horizontally, from the hair ends toward the scalp, producing an even, classic curl. Standard for most short-to-medium wraps.
  • Spiral — the hair is wound vertically or diagonally along the length of a long rod, producing a corkscrew/loose curl for long hair. Each layer overlaps the last like a spiral staircase.

Putting It Together

A typical wrap sequence:

  1. Section the hair into the chosen pattern (9-block or bricklay).
  2. Take a subsection the width of one rod.
  3. Comb the hair smooth, then fold an end paper over the ends (no creases).
  4. Wind onto the rod in the chosen pattern (croquignole or spiral).
  5. Set the rod at the chosen base placement (half-base default) and secure.
  6. Repeat, keeping even tension throughout the head.

Consistency is the whole game: uneven subsections, skipped end papers, or rods placed at different base placements produce a patchy, uneven curl that no amount of neutralizer can fix.
