Makeup and Brow/Lash Services
Color and face
Know the primaries (red, yellow, blue) and secondaries (orange, green, violet) and how complementary pairs neutralize: green cancels redness, orange cancels blue or bruising, lavender cancels sallow yellow. Match foundation to undertone (warm, cool, neutral) in natural light. Face shapes - oval, round, square, heart, oblong, diamond - are balanced with highlight and contour, not corrected with heavy lines.
Sanitation of makeup
Never double-dip. Decant cream and liquid products with a disinfected metal spatula onto a palette, use disposable applicators, and use a fresh mascara wand every time. Sharpen pencils before use. Clean and disinfect compacts and brush handles; wash brushes with soap and water and dry fully.
Brow and lash tinting
Perform a patch test 24 to 48 hours before the service, even when the client has been tinted before, and document the result. Do not tint over abraded, inflamed, or sunburned skin, and never on a client with a prior reaction. Keep product out of the eye and remove with the manufacturer's remover.
Lash services
California has no separate eyelash extension license; a licensed esthetician or cosmetologist may apply extensions, but training and manufacturer instructions still govern. Keep the client's eyes closed, isolate lashes, use fresh adhesive per the label, and postpone service with conjunctivitis, a stye, recent eye surgery, or an allergic reaction.
Trap watch
Wiping a mascara wand with alcohol and reusing it is a violation; so is skipping the patch test because the client has had tint before. Never share lip or eye products directly from the container.
Rule of thumb
If an applicator touches a client, it is finished - disposable or disinfected before it touches anyone else.
