Skin irritation and allergy

Skin irritation and allergy

In certain individuals, the use of hair coloring can result in allergic reaction and/or skin irritation.

Symptoms of these reactions can include redness, sores, itching, burning sensation and discomfort. If any of these symptoms occur, alert your hair colorist immediately so that they can remove the color. Symptoms will not always be present right at the application and processing of the tint but can also arise after hours or even a day.

To help prevent or limit allergic reactions, the majority of hair color products recommend that the client conduct a patch test before using the product. This involves mixing a small quantity of tint preparation and applying it directly to the skin for a period of 48 hours. If irritation develops, manufacturers recommend that the client not use the product. A skin patch test is advised before the use of every coloring process, since allergies can develop even after years of use with no reaction.

Adverse reactions can result from both at-home and salon hair coloring products, as similar chemicals are used in both settings .

In some cases, allergic reactions are caused by the aniline derivative and/or p-phenylenediamine (PPD) found in permanent hair color.

In some cases, if itching, burning sensation or discomfort occur and one does not alert the hair colorist immediately, it could result in hair loss.
