Hi, in your last video about losing hair, you mentioned that you should always test products like hair dye first before applying them to your scalp. Can you tell me how I would go about that?
YouTips4U: Hi, people with sensitive skin should be extra careful when using new products especially things like hair dye. A great way to test to see if you have an allergic response to a product is to do a patch test. Simply place a few drops or smudges of the product onto a band-aid and stick it to your inner forearm. Leave it there for about 24 hours and do not get it wet. After 24 hours have passed, remove the bandage and check for any redness, itching or blisters. This process should be repeated for a second and then a third 24 hour period. If you do not notice any irritation and skill looks smooth and clear after the entire 72 hour process, then your product is fine to use.
