My testing

Step 1 · Start with clean, dry hair

Simply wash your hair and make sure it is dry and free of hair products.

Step 2 · Snip a small amount of hair

You don't need a lot of hair. Even one piece of hair is enough. If you have short hair or are bald, it is Ok to take the hair sample from anywhere on your body. If that is not possible you can opt for a fingernail clipping instead.

Step 3 · Place it in a small plastic sandwich baggy

Seal your hair sample in a small plastic sandwich baggy and label it with your full name and date of birth.

Step 4 · Put it in a small envelope with a stamp

Place the plastic baggy into a small envelope with a stamp and mail it to the address found in your private portal.

Step 5 · Upload a recent selfie in your portal

Take a selfie of what you look like currently and upload it into your private portal.

Step 6 · Mark it mailed in your portal

Open My Testing and select “I Mailed My Sample.” Add the date, carrier, and tracking number if you want Dr. Kimberly to be able to notify you upon its arrival in your portal.
