Patch Test Guide

A patch test is a good way to determine how you will react to a product you’ve never used before. Below is a general method for conducting a patch test.

  • Clean a small area of skin inside your elbow or behind your ear.
  • Apply a small amount of the product to the clean area.
  • Leave on for 24 hours and keep the area dry in the meantime.
  • After 24 hours, rinse the area and observe. If you experience any redness, burning, itching, blistering, or irritation at any time throughout the test, do not use the product.

It is especially important to perform this patch test if you have sensitive skin. A patch test does not mean you will have similar results when applied to your hair and scalp.

It doesn’t account for underlying conditions and should not be used for the diagnosis of hypersensitivity or allergic contact dermatitis.

If you are concerned about incorporating a new product into your hair care regimen, please consult a dermatologist prior to use.
