The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "thin or thick head hair" as a symptom. For example, zinc need.

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:

absent sexual desire

prednisone use

moderate frequency of sex

reduced sense of taste

history of polyps

PPI antacid use

unpleasant smell sensations

history of deformed toenails

history of adult acne

non-human estrogen use

discontinued iron supplementation

brittle fingernails

... and more than 20 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of thin or thick head hair.

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Hair-Related Symptoms section of the questionnaire, The Analyst™ will ask the following question about head hair density:

How dense (thick) is the hair on your head in areas that are not affected by any type of hair loss?

Possible responses:

→ I'm bald / my whole head is affected by hair loss
→ Very sparse/thin
→ Somewhat sparse/thin
→ About average / don't know
→ Dense/abundant/thick

Based on your response to this question, which may indicate very sparse head hair, sparse head hair or abundant head hair, The Analyst™ will consider possibilities such as Zinc Requirement.
