Taking a hair sample is easy
Wash your hair and rinse well, leave to dry.
Do not use styling products before taking the sample. If your hair is treated or coloured, please wait 6 weeks before taking a sample from the new growth.
If however your test is urgent, please go ahead as it’s rare for dye to affect a sample, we just like to err on the side of caution.
As close to the scalp as possible, cut small amounts of hair from the nape of the neck and back of the head as this reflects the most recent metabolic activity in the body.
If your hair is less than 3cm long (1.5 inches) keep all of it for testing. If it’s longer, keep the 3cm of hair that was closest to the scalp and discard the rest.
When you have the sample ready, simply pop it directly into the envelope provided
– no need to wrap or cover with anything.
The amount of hair should completely cover the box on the back of the envelope (approximately 1 heaped teaspoon full).
Be sure to cut the first 3cm of hair closest to the scalp from this area.
