# How to Take an HTMA Hair Sample at Home

Step-by-step guidance on preparing for your HTMA hair sample, including advice for dyed or treated hair.

One of the reasons HTMA is accessible to an international audience is that sample collection happens at home, with no clinic visit required. Here's what to expect.

## Before you start

Once you begin your HTMA package, you'll receive written instructions and everything needed to collect your sample. In general:

- Wash your hair as you normally would in the days before collection, avoiding heavy styling products right beforehand.
- Have a clean pair of scissors and the collection envelope provided ready.

## Taking the sample

A small amount of hair is clipped close to the scalp, usually from two or three different areas of the head (for example, the nape of the neck), so the sample reflects overall growth rather than one isolated area. The amount required is small — comparable to what falls away during a routine trim — and the process is not painful.

## Dyed, bleached, or chemically treated hair

Chemical treatments such as colouring, bleaching, or perming can affect certain readings. This doesn't necessarily rule out testing, but it's important to mention any treatments when you begin your HTMA, so it can be factored into how your results are interpreted.

## Sending your sample

Once collected, your sample is placed in the provided envelope and sent to the laboratory using the shipping instructions included in your package. From there, analysis typically takes some weeks before your results are ready to review.

## What happens next

After your results arrive, you'll meet Valerie online for a private consultation to go through your report and receive your personalised plan. See [How It Works](/how-it-works) for the full process, or head to [pricing](/#pricing) to get started.
