Patch test
explained.

Updated

In plain English

A patch test is a product-sensitivity check performed before treatment according to the relevant product and professional instructions.

Also seen as: Sensitivity test

What the term means.

A clear result is useful but is not a guarantee against a later reaction. Treatments can use different products, so a check for one tint, lift system or adhesive does not automatically cover every other formulation.

Flirty asks new clients to allow at least 48 hours for the relevant lash or brow patch test. Confirm the required appointment before selecting the main treatment. Tell the studio about previous reactions or changes since the last visit rather than assuming an old test elsewhere covers a new product.

These are industry definitions. Product names, profiles and availability vary; your artist selects the actual system and construction for your appointment.

A common question.

Is a patch test a consultation?

No. A consultation discusses suitability and preferences; a patch test is a specific product check. Permanent brows begin with their own consultation process.
