They should make two tests.
One is a patch test to be sure you're not sensitive to the products.
The other is a curl test to see how well your hair will take curl from whatever perm solution they're thinking of using.

How is a incompatibility test done before perming the hair?
1. Protect your hands by wearing gloves. 2. Place a small cutting of hair in a small dish. 3. Pour into the dish a mixture of 20 parts of 6 per cent hydrogen peroxide and one part ammonium thioglycolate (general purpose perm lotion). Make sure that you are not bending over the dish to avoid splashing the chemicals on to your face or inhaling any resultant fumes. 4. Watch for signs of bubbling, heating or discolouration. These indicate that the hair already contains incompatible chemicals. The hair should not be permed, coloured or bleached if there are any signs of reaction. Perming treatment might discolour or break the hair and could burn the skin.

How is elasticity test done?
This is to test the internal strength of the hair (the cortex). Hair that has been damaged due to chemical treatments may have lost much of its natural strength. This type of hair may stretch over two-thirds of its original length and may even break off. It is important to carry out this test before perming. Hair that is in good condition will stretch and then return to its original length. Take one strand of hair and hold each end firmly between the thumb and forefinger of each hand and gently pull. If the hair stretches more than half of its original length then it is over elastic and may snap or break during chemical processing.

Will perming your hair help pass hair follicle test?
Depending on how you mean this question, I have the following answers for you: If you meant, "Will dying your hair help", the answer is no. Hair dye, bleach, etc. only effects the outside of the shaft; not the core, nor the follicle itself (which it typcally can't reach anyway). If you meant, "will dying help you pass this test", being dead makes the hair follicle test irrelevent, at least from your point of view, although it's probably way too extreme a response to the prospect of a drug test.
What is a preliminary test?
