How to cut your hair sample
The sample should be taken from as close to the head as possible, up to an inch in length, with total volume of a tablespoon. This sounds like a lot (enough for a test and re-test), but when taken from a few different places on the back of the head, one will not normally notice at all. If you have very short hair, you may need to grow the hair for a couple of weeks (it does not matter how short the hair is, only the total weight). Any orders without enough hair will be requested again.
Be sure to cut the hair 6-24 hours after washing with a simple shampoo and no other hair products e.g.conditioner or hairspray etc. Anti-dandruff shampoos such as Head and Shoulders or a selenium based shampoo should be avoided for accurate results. If you have dyed your hair, be sure to have washed it a few times after dying.
TINTS AND DYES. These rarely affect the test because they do not contain any minerals. Therefore, you may sample dyed hair. Ideally, take a hair sample before dying your hair. Ideally, do not dye your hair or use only natural hair dyes.
PERMANENTS OR BLEACHED HAIR. These treatments somewhat alter the structure of the hair. Sample the hair before a treatment, or wash the hair five times after a bleach or permanent treatment, before sampling the hair.
IF YOUR HOME HAS A WATER SOFTENER. Before sampling hair you must shampoo it twice with unsoftened tap water or reverse osmosis water from the supermarket. Do not drink reverse osmosis water as it does not hydrate the body well enough.
Send your hair sample
Prepare your hair sample as directed, then send to the lab (address below) with the two forms found at the bottom of this page. You do not need my signature as I have directed the lab otherwise.
The hair test takes approximately 2 weeks to be emailed from the lab, so post at your next opportunity.
Please download the following two forms at bottom of this page and send both parts to address below:
Analytical Research Labs
2225 W. Alice Ave.
Any problems to firstname.lastname@example.org
If you cannot download the forms I will ask you to send you hair to me, it just takes a little longer this way.
