Indola a European colour line recommend an Incompatibility test. We did them when we were at college and it really bubbles if they have incompatible chemicals in the hair. This is what Indola say on their site:


Incompatibility test
Perm lotions and other chemicals applied to the hair may react with other chemicals that have already been used such as compound hennas, metallic salts, progressive colours, home use products etc.
An incompatibility test should be carried out to detect chemicals, which could react with a colour or perm process used by professional hairdressers.
• Protect the hands by wearing gloves
• Measure 2 fl.oz liquid hydrogen peroxide 20 Vol plus 2 drops of household ammonia (ammonium hydroxide) in a non-metallic bowl.
• Place a small cutting of the hair into the liquid.
• Watch for signs of bubbling, heating or discolouration. Any of these signs will indicate that the hair contains incompatible chemicals.
• The hair must not be permed, tinted or bleached if any chemical reaction is present in the hair.
There is no recognised method of removing incompatible chemicals from the hair. The client should be advised that cutting the hair until all the hair containing these types of chemicals has been removed
