HD Brows and BrowSculpt patch testing

Here at HD Brows, we are always looking for ways to improve our offering to support the growth of your eyebrow empire. That’s why we’ve taken a look at our patch testing policy.

Why patch testing for brow treatments is important?

Patch tests are important for insurance reasons, your client’s experience (they could react to the products used in your treatments) and demonstrating that you’re a professional #BrowBossAs they are so important, we have made some changes to the HD Brows and BrowSculpt patch testing process to make things better for you long-term.  

The HD patch testing process

Here’s everything you need to know:

  • - Patch tests do not need to be carried out for every HD Brows or BrowSculpt treatment.
  • - Patch tests are required prior to the first treatment, then after 6 months (if they haven’t had a treatment in that time).
  • - An additional patch test must be carried out if there are any changes to your client’s medical situation.
  • - You must wear gloves during your treatments and patch testing clients, to prevent repeat exposure to treatment chemicals and minimise contact with skin.
  • - We will be discontinuing our transfer patch tests.

    Can I still buy patch tests from HD Brows?

  • Our tint transfer patch tests have now been discontinued and will no longer be available to purchase. Going forward, when a patch test is required, you will need to carry out a manual patch test with some Brow Dye, mixed with Brow Dye Developer

    Why did the patch testing process change?

  • After seeking professional advice, we have taken the decision to make some changes to our patch testing process. The main reason is to minimise exposure and limit the possibility of increased sensitivity to the chemicals in patch tests for both you and your clients. We’re always trying to make things smoother for our stylists. Reducing the frequency of patch tests will reduce the time and money spent on facilitating these and can make the client booking process more flexible.

    What should I use to patch test for tint?

  • It’s easy! Simply mix a small amount of Brow Dye and Developer together and apply to the inner arm.

  • +

    Can clients do their own patch tests?

  • Some insurance providers prefer the patch test to be carried out in sight of a professional, others are happy for the client to do this at home. Check your insurance policy documents for details.

  • +

    Does this mean I need to re-patch test all clients?

  • As long as your clients don’t meet any of the patch testing criteria (a new client, those who have not had the treatment for 6 months, or any medical changes), you will not need to patch test again.

  • +

    Can my client sign a waiver form instead of doing a patch test?

  • Some insurers are happy for you to proceed with a treatment having offered the patch test which has been declined by the client but will require a signature to confirm they have declined the test. Most insurers will not cover you unless a patch test has been undertaken so a waiver would be unacceptable. Their requirements will be clearly defined in your policy documents.

  • +

    Do these patch testing changes impact my insurance?

  • Please check your insurance policy documents.

  • +

    How long should patch tests be left on the skin?

  • 48 hours. When a new product is introduced to the skin it can take up to 48 hours for the skin to show a reaction to it, following this expert advice of dermatologist Justine Hextall, we choose to leave patch tests on the skin for 48 hours in total. Although a patch test does not guarantee no subsequent reactions, it should eliminate the majority of cases.

  • +

    Does the Covid-19 vaccine impact when and how we patch test customers?

  • There is currently no official advice from the government, the vaccine manufacturers or our own insurers with regards to conducting treatments and patch tests on clients who have received a vaccine and/or have previously tested positive for Covid-19.

    After your client has received the vaccine, you may choose to wait to undertake a patch test to help ensure the side effects are not confused with a patch test reaction. Otherwise, standard patch testing guidelines apply.

    As a change in medical history requires a patch test to be carried out, a patch test should be carried out before a treatment is performed on a client that has suffered from Covid-19 or received a COVID-19 vaccine (please note, any vaccine is considered a change in medical history).
