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.
