The 4B Hair Routine That Reduces Knots and Holds Definition
4B is the Z-bend texture that holds twist-outs beautifully — when you stop fighting it.
Introduction
4B forms angular Z-bends rather than coils. It shrinks dramatically, but holds definition longer than 4A in twist-outs and braid-outs.
4B traits
- Sharp Z-bends with little visible spiral
- 50–70% shrinkage
- Prone to single-strand knots
- Loves creamy stylers
The single-strand knot problem
4B's tight bends make it the most prone to knots, where a strand loops back on itself. Three rules: keep ends moisturized, keep ends stretched, and dust regularly. Search-and-destroy knots monthly with sharp shears.
The 4B wash day
Pre-poo with warm oil
Coconut + jojoba for 20 min
Cleanse + detangle wet
Conditioner-coated, finger first
Deep condition with heat
20–30 min under a hood
LOC styling
Liquid → Oil → Cream
Stretch in 6–8 twists
Air dry until 90%
Best 4B styles
