Makeup and Eyelash Services
Color theory applied
Know primaries, secondaries, tertiaries, and complementary pairs (opposites on the wheel) because correctors rely on them: green neutralizes redness, peach or orange softens blue undertones, and yellow brightens purple bruising. Match foundation along the jawline in natural light and identify undertone - warm, cool, or neutral. Face shapes (oval, round, square, heart, oblong) guide contouring, highlighting, and blush placement rather than a single "correct" look.
Sanitation in makeup
Makeup is a microbial risk area. Never double-dip mascara or lip gloss; use disposable wands and spatulas, scrape product onto a palette, sharpen pencils before and after use, and wash or disinfect brushes between clients. Sponges and wands are single-use. Keep lids closed and discard expired or contaminated products.
Eyelash services
Eyelash extensions use cyanoacrylate adhesive applied to isolated natural lashes; volume sets attach multiple fine lashes to one natural lash. A lash lift perms the natural lash. Always patch test adhesive 24–48 hours ahead, keep adhesive fumes away from the eye, and work with the eye closed. Contraindications include eye infection, blepharitis, recent eye surgery, active allergies to adhesive, and trichotillomania; clients should avoid waterproof mascara and oil-based removers on extensions. Removal uses the manufacturer's remover, never pulling.
Traps and a worked example
Questions reward "disposable wand every time" and penalize sharing mascara. Worked example - a client with diffuse redness wants an even complexion: a sheer green corrector under foundation neutralizes red better than piling on concealer.
