Yes. Because DermMatch is applied directly to the scalp, we recommend that all new users perform a standard patch test to rule out any rare ingredient sensitivities.

How to do a patch test:

  1. Use the applicator to dab a small amount of product onto a clean patch of skin behind your ear or inside your elbow.
  2. Leave it on and keep the area dry for 24 hours.
  3. Check the area for any signs of redness, swelling, itching, or irritation.

If your skin looks normal, you can proceed with full application. If you experience an adverse reaction, wash the area immediately and discontinue use.
