You can try different methods of cutting and styling on the manikin before trying on real hair to prevent dissatisfying yourself or the person whose hair you are styling.

Skin tests in hairdressing are used to check that a client is not allergic or sensitive to the ingredients in a colouring product prior to treatment. A mixture of the colour with hydrogen peroxide is dabbed onto the clients inner elbow or behind the ear 24 - 48 hours prior to the colouring treatment. If the skin shows signs of redness, itching or swelling then the treatment should not be undertaken.
