Dandruff

What Causes Dandruff?

Dandruff can have various causes, ranging in severity from 'worrying' to 'very serious'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose dandruff, 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 "dandruff" as a symptom.  Here are six possibilities:
  • EFA Need
  • Sjogren's Syndrome
  • Vitamin B6 Need
  • Liver Congestion
  • Psoriasis*
  • Hypothyroidism
* symptoms can be very similar

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:
severe afternoon/evening fatigue
short-term memory failure
being a lethargic person
low T3 free level
low free T4
T4-only thyroid hormone use
highly elevated ANA levels
severe shoulder tightness
depression with anxiety
slow reaction time
discontinued non-human estrogen use
major joint pain/swelling/stiffness
... and more than 110 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of dandruff:
Cause Probability Status
Liver Congestion 91% Confirm
Hypothyroidism 59% Possible
EFA Need 28% Unlikely
Sjogren's Syndrome 2% Ruled out
Vitamin B6 Need 0% Ruled out
Psoriasis** 0% Ruled out
* This is a simple example to illustrate the process
** Symptoms can be very similar

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 Existing Skin Conditions section of the questionnaire, The Analyst™ will ask the following question about dandruff:
Do you have dandruff (Seborrheic Dermatitis)?
Possible responses:
→ No / don't know
→ Some
→ Significant
→ Severe
Based on your response to this question, which may indicate either dandruff or severe dandruff, The Analyst™ will consider possibilities such as:
EFA (Essential Fatty Acid) Requirement

A diet low in essential fatty acids can result in skin problems, such as dandruff.

Hypothyroidism

Hypothyroidism can manifest as dry, flaky skin.

Vitamin B6 Requirement

A vitamin B6 deficiency can cause dandruff.
