Please read the following instructions VERY carefully. It’s important to take the sample correctly otherwise the lab may not be able to use your sample, resulting in delays and having to take extra hair for a new sample.
Hair Sample Instructions
Here’s a little more detail on the sampling and testing process so that you can understand why it’s important to be careful when taking your sample. The aims of the process are:
Avoiding Contamination
Preparing to Take Your Hair Sample
Sensitive Scales
For anyone that is concerned about taking too much hair for the sample, I highly recommend purchasing a cheap pair of sensitive digital scales to take the sample, something like this. They will need to be sensitive enough to measure the sample accurately at 125mg – it is a small investment for peace of mind.
Sampling With a Hairdresser
Either ensure that you can explain clearly to the stylist how to take the sample, OR print out these instructions and give them to the stylist so they understand how to take the sample correctly.
How to Prepare Your Hair
1
Wash your hair with shampoo, but do not use any conditioner or additional products, not even if you intend to wash them out
2
You can dry your hair naturally or with a hair dryer
3
Do not use any type of products on your hair
4
Take the hair sample between 4-24 hours after it has been washed (if you live in a particularly damp place, please ensure that the hair is completely dry before you take the sample)
Head Hair
Please use head hair wherever possible.
If you have head hair but you just cut it short / shave:
When you’re ready to trim your hair / shave, follow the instructions above for washing your hair and when you’re ready to take the sample, please use a clean pair of hair clippers. If there is not enough hair the first time you trim your hair, keep the hair cuttings in a clean envelope until the next time you want to trim your hair and repeat until you have enough cuttings in the envelope for a full sample.
Body Hair
If you have no head hair growing on your head:
You can use beard or underarm hair, but please only use one type of hair and ensure that it meets the length requirement. Pubic hair is best avoided as it is less accurate, it can only be accepted if there is no other option.
If you are not using head hair, please note this on your HTMA order form and in your questionnaire.
