01Hairdressing and Hair Care
The hair shaft has three layers: the cuticle (overlapping protective scales), the cortex (keratin bundles and melanin), and the medulla (central core, often absent in fine hair). Hair is acidic at about pH 4.5–5.5; alkaline products raise the cuticle and increase porosity. Porosity and elasticity tests guide service selection: high-porosity hair absorbs and loses moisture quickly, while normal wet hair stretches about 50% and returns without breaking. Perform a patch test 48 hours before oxidative dye and a strand test for development timing.

The skin has three main layers: the epidermis (stratum corneum barrier), the dermis (collagen and elastin), and the hypodermis. Skin surface pH is about 4.5–5.5. The Fitzpatrick scale (I–VI) estimates sun sensitivity and guides treatment intensity. Identify skin type - normal, dry, oily, combination, sensitive - and note contraindications before any facial.

The nail plate is keratin; it sits on the nail bed. The matrix produces the plate, and its visible portion is the lunula. The cuticle is dead tissue sealing the nail; the eponychium is the living fold, and the hyponychium lies under the free edge. Do not cut living tissue.

Makeup artistry depends on undertone (warm, cool, neutral) and depth. Match foundation on the jawline in natural light, not on the hand. Correctors neutralise colour: green reduces redness, peach/orange corrects blue undertones, and yellow brightens dullness. Choose products for the client’s skin type; oil-free formulas suit oily skin, cream formulas suit dry skin.

Salon safety follows a hierarchy: cleaning removes visible soil with detergent; disinfection kills most pathogens on non-porous tools; sterilization destroys all microorganisms and spores, usually by autoclave for invasive items. Keep client records, informed consent, and patch-test results. Maintain safety data sheets (SDS) for chemicals, label secondary containers, and store acids and bleaches securely. Manage appointments, inventory, pricing, and waste segregation.
