Tests before a technical service

• Skin Test- Skin tests are performed to ensure there are no allergies or irritation to the products we use. Prior to carrying out a colouring service a skin test must be carried out 48 hours before (unless they have had a colour within the last 3 months by us). A skin test is done by applying a small amount of colour behind your ear.

• Porosity/Elasticity Test - An elasticity test is done Before any chemical treatment or part of our consultation process, we will take a single strand of damp hair  and gently stretch it to test the structure of the hair. When the hair is in good condition the hair should stretch back to normal. Hair with poor elasticity will not return back to normal length and could be damaged further or break off if a colour is applied. A porosity test is done before any chemical treatment or part of our consultation process, on dry hair. We will take a small section of hair and using the thumb and first finger we stroke hair from points to roots. This is to test the external structure (the cuticle) of the hair and the absorption. Your hair should feel smooth, rough hair will indicate your hair is very porous hair. Porous Hair could be damaged further by chemical services or may result in the chemical process being uneven and fading quickly.

• Strand Test -This test is performed during the colouring process. It is to check a bleaching or toning process to ensure the achievement of the correct shade required.

• Test Cutting-  A test cutting is very important in situations where the hair is damaged or the intention is to attempt a dramatic alteration to the colour of the hair. Test cuttings are used in colour processes to ensure that the hair will respond properly to the processes planned, and that said processes won't result in damage to the hair. It's also important when our stylist cannot be certain what other colours or chemicals have been used on the hair in the past.
