Step 1: Wash your hair
If your HTMA purchase is for a canine sample, skip to step 5. Sample collection instructions will be on the linked submittal form.
Before cutting the hair sample, wash your hair with regular shampoo. Do not use dandruff shampoos as these shampoos often contain minerals that may alter the test results. For example, Head and Shoulders Shampoo contains zinc which could elevate the zinc reading, and Selsun Blue Shampoo contains selenium which can elevate this reading.
For best results, avoid using conditioners before cutting your hair sample. Do not place other products on your hair such as leave-in conditioners, hair gel, hair cream, hair spray or others until after you have cut the hair sample.
Hair Color is ok -- Hair color, dyes and tints do not affect the test because they contain chemicals, not minerals, but it’s best to wash the hair at least once after applying a tint, dye or color rinse before cutting a hair sample.
Bleach, highlights and perms can alter the structure of the hair. So either sample the hair before a treatment or after you have washed the hair five or more times following a lightening, bleaching or perming treatment. The hair tends to re-balance after five washings. Since highlights are done on the surface of the hair, you can simply sample a piece of hair that has not been highlighted on the underside of your hair.

Step 2: Let hair dry for 4 hours
After washing your hair, wait at least 4 hours to cut the sample but no longer than 24 hours. Hair needs to be dry when sampling, so avoid putting wet hair in hats, ponytails or any other style that will prevent the hair from drying by the time the sample is taken.
Avoid any activity that will cause you to sweat excessively before cutting your sample, as this may affect the hair analysis results.

Step 3: Cut the hair sample
Using clean scissors, cut hair as close to the scalp as possible. DO NOT use an electric razor to cut the hair sample because pieces of metal from the blades become mixed with the hair sample.
You may cut the samples from any part of the head but we recommend the back of the head, as it often grows fastest. It is best to take hair samples from a few different places on the scalp.
Keep track of which end of the cut hair is from the scalp because we only want the inch or so of hair that was directly against your scalp! This is because the hair furthest from the scalp is the oldest. Older (longer) hair will show us the chemistry of your body months or even years ago, so it is not accurate for your body’s current chemistry. To get the hair required for a hair mineral analysis, cut and discard the unwanted ends until all you have is 1 inch (2.5-4 cm) of hair from the scalp. Use a ruler to be sure you have the right length of hair!Â
You will have enough hair when the 1-inch (2.5-4 cm) hair sample fills a FULL TEASPOON. If you are unsure if you have enough hair, send a little more to be safe. For repeat hair analyses, it’s best to keep the samples no longer than one inch (2.5 cm).

TIPS FOR SHORT HAIR:
You can avoid leaving bald spots by cutting multiple very small samples from all over the head.
Â
TIPS FOR MEDIUM-LENGTH OR LONG HAIR:
You can easily hide the sample location by pinning part of your hair up to expose the center of the back of your head and cutting the sample from UNDER the hair, about 2-3 inches (5-7.6 cm) above the base of the hairline. That way the sample spot will be hidden whether you wear your hair up or down. This also allows you to easily find the same spot when you do a repeat hair mineral analysis after 3-4 months: you simply cut the new growth from the same spot.
Step 4: Get ready to mail your hair sample!
Once you have cut your hair sample, place it in a small PAPER envelope. Do not place hair samples in plastic baggies, tin foil or stapled or taped to forms. Place the hair in a paper envelope and write your name, age and sex on the envelope. Your hair sample should be the ONLY thing in this envelope.
