Foundations of Beauty and Wellness
This domain tests the basic science behind every salon service: the structure and function of skin, hair and nails, the meaning of wellness, and how to judge whether a treatment is safe to perform. Questions often ask you to name a layer, match a function to a structure, or spot a contraindication during consultation.
Core facts to hold
- Skin has three main layers: epidermis (avascular, keratinised barrier), dermis (collagen, elastin, vessels, nerves, follicles, glands) and subcutaneous layer (fat, insulation, shock absorption).
- Skin functions: protection, temperature regulation, sensation, excretion, secretion, absorption and vitamin D synthesis.
- Hair has three layers: cuticle (protective outer scales), cortex (keratin bundles and pigment) and medulla (central core, often absent in fine hair).
- Nail: plate, matrix (makes the plate), cuticle, lunula (visible matrix), hyponychium (seal under the free edge).
- Wellness is multidimensional: physical, emotional, social, occupational, intellectual, spiritual and environmental.
Worked example
A client has shine on the nose and chin, visible pores, but tight cheeks after cleansing. Reasoning: shine plus visible pores indicates excess sebum (oily); tightness after cleansing indicates dehydration, not dryness. Sebum and moisture are separate, so the description is oily-dehydrated, and the plan is gentle cleansing plus oil-free hydration, not an aggressive astringent.
Traps that cost marks
Calling the epidermis vascular; confusing dehydration with dry skin; naming the medulla as the pigment layer; treating a contraindication as a minor detail.
