Hair and Scalp Care

What this domain tests

This domain covers recognition, hygiene, and treatment of scalp and hair conditions within barber scope, plus product chemistry and styling-related damage.

Core rules and concepts

  • Hair properties: texture, density, porosity, and elasticity. Curl pattern is descriptive, not a diagnosis.
  • Common findings: dandruff (pityriasis), seborrheic dermatitis, dry scalp, product buildup, folliculitis, traction alopecia, alopecia areata, and telogen effluvium.
  • Shampoo chemistry: surfactants lift oil and soil; conditioning agents smooth the cuticle; pH affects feel and shine.
  • Traction alopecia is preventable: loosen tight braids, edges, and ponytails, and vary styles.
  • Massage: supports circulation and relaxation, but avoid inflamed or broken skin.

Worked example

A client has thinned, receding temples and wears tight braids. Reasoning: the pattern and style history fit traction alopecia. Advise loosening the style, alternating with low-tension options, and referring if regrowth does not follow tension relief. Do not treat it as dandruff or as a styling problem alone.

Traps that cost marks

  • Labeling all flaking as dandruff.
  • Overconditioning fine hair and flattening it.
  • Treating alopecia areata as a styling issue.
  • Massaging over inflamed or broken skin.
