Please follow instructions below closely.
This is important for an accurate test result.
We need about a full tablespoon of hair.The hair on the back
of the head often grows
fastest and is easiest to sample.
However, any part of the head may be used and you
beard hair or body hair if absolutely needed Otherwise, please use hair from
the back of the head if at all possible, as it is the best and most accurate.
Hair Preparation: Make sure your hair has been washed, preferably with a mild soap or with shampoo, within 48 hours. Using a conditioner or rinse is okay, but it would be best to use only a mild shampoo for the best results. Do not place other products on the hair just before cutting the hair sample such as hair cream, hair spray or others.
Tints, dyes, color rinses (such as henna) and highlighting: These can be on your hair when you cut a sample for analysis. We are aware that some laboratories do not allow these products or hair treatments when taking a sample for a hair analysis. However, we find that they usually no not affect the test enough
to force you to wait for weeks to send in your sample. In fact, most tints, dyes and rinses do not contain many minerals so they will not affect the test at all. The more natural the hair, however, the better.
Bleaches and Permanents: After a bleach or permanent, especially a beauty parlor permanent, wash your hair four or five times before sending in a sample. The chemicals used can affect the hair structure. However, the hair will recover after several washings, as a general rule.
Hair Cutting Procedure: Cut several small snips of hair as close as possible to the scalp. You may cut the samples from along the sides, top or back of the head. Place the samples on a clean table with the cut end facing you. Now cut off any long ends of hair that are over 1 inch (or about 2 centimeters) long. The long ends of hair are older and are not as good for sampling. The new hair, near the scalp, is much better.
You will have enough hair when the 1-inch cut samples will fill an ordinary tablespoon. Combine these and place in a clean, small paper envelope. Write your name, age and date of the hair sample on the envelope. Now you can add the small envelope of hair sample with the signed health form and put both in a regular size envelope.
Do not use pubic hair, as it is less accurate, unless you have no other option.
Note: The hair sample size should be at least one full tablespoon.
