Important: Patch tests are required for all clients from April 2021 for tinting, perming & lifting.
Patch tests are compulsory to carry out whenever there have been changes to the product and also changes to the clients medical history:
- Having a COVID-19 vaccine is classed as a medical change.
- If you’ve had COVID-19 this is classed as a medical change.
- The use of home tints / dyes could contribute to increase sensitivity to PPD (Paraphenylenediamine)
Please note: After someone has had a vaccine the NHS have advised that the patient could have side effects. To avoid confusing side effects with a reaction to a patch test is it advised you need to allow 2 weeks before or after a vaccination, before patch testing.
