PLEASE BE AWARE NO PATCH TEST IS 100% GUARANTEE THAT YOU WILL NOT HAVE A REACTION TO THE FULL TREATMENT.
A patch test is an important safety precaution to minimise the risk of allergic reactions or adverse effects from products or treatments. It involves applying a small amount of the product on a small area of the skin, on the inner arm, to assess if there's any adverse reaction.
However, you MUST understand that even if they pass a patch test, it doesn't guarantee you won't have a reaction to the full treatment. Factors like skin sensitivity, allergies, and individual reactions can vary, and a patch test may not always predict these.
