- 01 Distribution Observe density and variation by area without inventing a chairside count.
- 02 Fibre Record diameter variation, condition, previous work, and system context.
- 03 Behaviour Note pattern, grouping, shrinkage, movement, and wet or dry state.
- 04 Decision Agree the result and preserve areas, then trial an exact tool responsibly.
Do not inferCurl code, ethnicity, gender, texture word, or photograph cannot determine density, condition, tooth count, steel, edge, size, or technique.
Description
Type 4B is a visual label for tightly bent or zigzag/coiled pattern with less uniform ringlet definition than 4A. Client-specific assessment remains essential.
Tight Zigzag Coily Hair (Type 4B)
Quick look
- Visual vocabulary: Tightly bent or zigzag/coiled pattern with less uniform ringlet definition than 4A
- Not encoded by 4B: Porosity, density, delicacy, ethnicity, shrinkage, or tool choice
- Planning focus: Grouping, silhouette, mixed zones, and this client’s spring-back
- Control step: Release tension and recheck the actual section
Why it matters
Chart descriptions vary, so the label is best used as visual communication rather than a diagnosis. The same 4B label can include very different density, fibre diameter, condition, porosity, grouping, and wet/dry response.
Client-specific checks
| Observe | Why it changes the plan |
|---|---|
| Intended worn state | Defines where silhouette and length must be judged |
| Natural, wet, and stretched length | Measures individual spring-back without a 60–80% assumption |
| Density and distribution | Determines whether and where weight management is needed |
| Fibre condition | Knots, breakage, chemical/heat history, and weathering affect manipulation tolerance |
| Grouping and mixed zones | Guides section scale and whether pattern-led or structural work fits the goal |
Technique and tool choices
- Pattern-led dusting and conservative dry shaping are valid options when preserving the natural silhouette is the goal.
- Wet structural work, stretched cutting, and staged methods can also be valid. Use consistent tension and verify the result after release.
- Choose edge, blade line, size, clips, and product for the actual method and client. None is dictated by 4B alone.
- If using a toothed tool, rely on the exact model’s published cut rate and a conservative test placement, not a blanket permission or ban.
Service notes
Product, detangling, drying, and at-home care should be individualized to condition, sensitivities, routine, and product directions. Set maintenance from shape, ends, growth, manipulation, and client goals; there is no type-specific six-to-eight-week rule.

Context and comparison
Charts usually depict 4B with less uniform ringlet definition than 4A and more visible bend or grouping than some 4C depictions. This is not a fixed skill ladder or shrinkage hierarchy. Observe mixed areas and measure the actual client rather than assigning a percentage or training order from the letter.

Frequently Asked Questions
3 answers you can open one at a timeWhat does the 4B label tell a stylist?
Common charts use 4B for tightly bent or zigzag/coiled pattern with less uniform visible ringlet definition than 4A. The code does not establish porosity, density, delicacy, ethnicity, or a fixed shrinkage percentage.
What scissors work best for 4B hair?
Choose a sharp, maintained shear for the planned method, operator fit, section control, and the client’s actual condition. 4B alone does not require a convex edge, ban a razor or blender, or set a size, steel, or tooth count.
What techniques are recommended for 4B hair?
Conservative dry shaping can serve a natural-silhouette goal; wet, stretched, or staged structural methods can serve others. Standardize tension and recheck the result in the intended worn state instead of following a fixed 4B sequence.
