Dandruff Caused by Scalp Eczema or Psoriasis: Why it Occurs and How to Treat It!

For some women itchy scalp conditions such as seborrheic dermatitis, which includes eczema and psoriasis, are not just harmless medical issues that should be ignored.  In some cases, the constant scratching and brushing can become a social nightmare.  I mean seriously, how can a true fashionista claim her throne if she’s frantically brushing dandruff off her shoulders-sorry ladies but Jay-Z’s song, “Dirt Off Your Shoulders” doesn’t apply to these two serious scalp conditions.  So what’s a girl to do? First let’s look at the why seborrheic dermatitis conditions such as eczema or psoriasis occurs.


Why It Happens

 According to a team of researchers from Proctor and Gamble, dandruff occurs due to an abundance of both oil and a yeast-like fungus called malassezia globosa, which lives on your scalp and feeds on the oily products of the sebaceous glands.   When this happens, the fungus uses enzymes called lipases to metabolize the oils, and that process creates a by-product called oleic acid. The acid penetrates your skin and triggers the skin to shed-which is also known as dandruff.


The Cause


Eczema is generally caused by food allergens like nuts, wheat, seafood, eggs, and fruit; while on the other hand psoriasis is usually caused by environmental triggers such as the following:

  • SLS based soaps and detergents;
  • Synthetic fragrances (aka perfumes); and
  • Metals such as nickel (used in braces) or mercury, tin, copper, and alloy (metals that are in dental fillings in your teeth).
  • Medications
  • Poor Diet or malabsorption

The Triggers

Both conditions become worse with stress; however in addition, psoriasis becomes worse with cold, dry weather and tends to get better with sunny, warm, humid weather.  Since psoriasis acts like an autoimmune disease, any illnesses of the sinuses or a sore throat could cause the psoriasis to flare up again.

The Treatment

I. Topically

Luckily, treating eczema and psoriasis is relatively easy. Topical treatments for these conditions include:

  • Shampoos that have the active ingredient selenium sulfide or zinc pyrithione because these ingredients kill the fungus;
  • Oregano or tea tree oil applied to the scalp-these ingredients are anti-fungal, anti inflammatory, and anti-bacterial
  • Distilled vinegar or apple cider vinegar which are also antibacterial

II. Nutritionally


Both conditions are generally linked to food intolerances and multiple chemical sensitivities so it’s a good idea to clean up your diet-starting with a detox diet.

  • Omit grains, sugar, pasta, rice, and fruits from your diet because the odds are your intestinal gut flora is imbalanced and full of yeast/candida and these foods promote yeast in your body.
  • Eat more vegetables and natural meats
  • Add a high quality omega 3 fatty acid to your diet, such as Carlson’s Fish Oil or Cod Liver Oil
  • Add a vitamin D3 supplement to your diet. The odds are that you are very deficient in this vitamin. Please note that you don’t have to take a vitamin D supplement if you are taking cod liver oil because vitamin D is already added to the cod liver oil.
  • Add a probiotic supplement to your diet-I highly recommend Garden of Life’s Primal Defense Ultra Probiotic.
  • Add a digestive enzyme such as Garden of Life Omega-Zyme.

A healthy gut should be comprised of 85% good bacteria and 15% bad. Most people have just the opposite. So making these dietary changes will get your gut flora on the road to recovery. When your gut flora is healthy, your dandruff problems and most other medical conditions should just clear up naturally.
