Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose thin or thick head hair, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
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:
history of polyps
grooves across fingernails
coffee consumption
darker/redder skin color
history of deformed toenails
history of birth control pill use
calcium-based antacid use
frequent soy consumption
zinc test tasteless
H2-blocker antacid use
diuretic use
adult acne
... 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.
