Can I do lash or brow treatments on a client with an eye infection?

No — not while there's any active infection or inflammation around the eye. Conjunctivitis, styes, blepharitis, and any weeping or crusting lid are all contraindications for lash extensions, lash lifts, tinting, and brow work. The eye area is delicate, the tissue is already compromised, and adhesives, dyes, and tools sitting against an infected lid can spread it, worsen it, or transfer it to your kit and the next client.

What to do instead:

• Reschedule until the infection has fully cleared and the eye is calm — and, for anything bacterial or contagious, that means properly resolved, not just "looking better."
• Don't tint or lift "carefully" around it. Dyes and lifting solution near an inflamed eye risk a chemical reaction on top of the infection.
• Refer if unsure. Persistent redness, discharge, pain, or vision changes belong with a pharmacist or GP, not the lash bed.
• Record it. Note what you saw, that you declined, and the date. If a client later claims you caused an eye problem, that record is your defence.
