Skin Testing Policy and Procedure at Darren Michael Hairdressing

Colourstart Passport and AAT (Allergy Alert Test) in Oldham/Manchester

Darren Michael Hairdressing  has a skin testing procedure in place to protect us and more importantly our clients from adverse reactions to the chemicals and ingredients in 12.WVD MC2 modelhair colour. You do need an appointment for our skin test and needs to be 48 hours before your colour service. Should you experience any discomfort, tingling or reaction, clean the skin gently with warm water & inform us as soon as possible.

The reason you need to have a skin test at least 48 hours before your colour application is becausein particular circumstances the most severe form of hypersensitivity is a cell-mediated reaction that can take at least 48 hours to develop.

Reactions and skin complaints from hair colorant are rare, but as a salon our duty of care is to protect you prior to any colour application you wish to have with us. There has been an increase in reactions in recent years and many people develop hypersensitivity or allergies to things they never had a problem with before. The same is true for hair colour – you can develop a reaction at any time in your life. Certain medications can make some individuals react to hair colour others may suppress reactions. Thank you for your understanding & co-operation with the above.

We have two options for you to choose from:

1. A FREE AAT (Allergy Alert Test)

is required 48 hours before your hair colour appointment and is done by placing a small amount of mixed colour to your arm (only covered with a tissue when you put your coat on) and left on for 24 hours being careful not to wipe off. You will check the area with us via messenger or zoom to ensure there is no redness or swelling indicating an allergic reaction to the ingredients in hair dye/colour. All this is in accordance with our insurance and manufacturer instructions and is subject to change.

2. Colourstart Passport – a brand new way of doing skin tests that we are very excited about!

The MRHA, the government body that is responsible for the safety of all vaccines and medicines in the uk are giving full support to this scheme and have endorsed it as the safest method of skin testing in the UK. Skin testing in salons can often cause reactions applied too frequently. We have changed the way we will be skin testing in salon to follow their latest guidelines for safety, if you do require an in-salon test.

Medically from a government department this is the safest way to skin test in the UK.


Q: Why is hypersensitivity to hair dye only becoming an issue now?
A: There has been a dramatic increase in hypersensitivity in recent years – increased incidence, increased severity and increased complexity. Within the hairdressing industry, this is compounded with an increasing trend towards the use of darker hair colours.

Q: I’ve been colouring my hair for many years and have never had a reaction to hair dye. Why should I start testing now?
A: Every day, we witness how you can become hypersensitive to new things. Some people develop hay fever one year or find they become allergic to latex gloves. The same is true for hair dye. You can become sensitive at any time in your life.

Q: I’m taking medication. Will this affect the result?
A: Medication may vary your reaction to hair dyes. Some will make you hypersensitive; others may suppress your existing hypersensitivity.

*Please see Colourstart information to check your medication*
Q: Why do I need to test at least 48 hours before the application of a hair dye?
A: In certain circumstances, the most severe form of hypersensitivity is a cell-mediated reaction that takes at least 48 hours to occur.

Skin Testing For Scalp Application of Bleach.
We have to do a sensitivity test for bleach application and it is our duty of care to you to do a AAT as you may need a toner or another colour service which may cause an allergic reaction. We use Sensus scalp oil for every scalp bleach to ensure more protection for your skin and scalp.

Every person has a different tolerance or sensitivity to Scalp Bleaching. Factors such as skin type (oily/dry etc), ambient room temperature and skin temperature on different parts of the scalp are all factors on how bleach works.

It is normal to feel an Itching or tingling feeling – even a mild burning sensation when the bleach is first applied.

Try not to shampoo your hair on the day of application as this seems to help and if you do feel any major increase in levels of discomfort due to the Bleaching Process please inform your stylist IMMEDIATELY.

If you don’t inform your stylist of this discomfort which is increasing  – can result in a chemical burn to your scalp.
