Just Allergies…?

In my research I have been looking into John Kender’s idea that people with trichotillomania have a natural biochemistry irreversibly inclined towards certain allergic reactions. They are allergic to a normal yeast (Malassezia) that is found in the skin and gut of virtually everyone, but they react to it with itching and irritation and a need to remove the allergen. I have posted an insightful article below.

Trichotillomania and Dermatillomania: A root analysis

 with special thanks to Jeannette Johnson for her kind advice and attention. 

Hair roots contain sebum.  Sebum contains fatty acids and tryglycerides, and plays a role in some crucial body functions, such as hydration, inflammation, antioxidants, antimicrobial lipids, and pheromones.  Sebum levels increase during puberty and excessive levels of sebum are often associated with skin problems, making it relevant to skin picking and hair pulling.

Why is this so relevant?  You probably know that the body’s energy levels revolve around its production and use of insulin. a hormone which regulates fat and carbohydrate metabolism.  It is insulin which prompts cells to absorb glucose from the blood. In fat cells, glucose it is stored as triglycerides .. see above paragraph for relevance of tryglycerides.

A normal skin yeast, Malassezia, may be overgrown in people with trichotillomania and dermatillomania.  Overgrowth of malassezia is linked to higher levels of oleic acid in the sebum, which we think is caused by a delta 6 desaturase deficiency.  According to wikipaedia, Malassezia is related to most skin disease in humans, certainly to eczema and acne.  Malassezia growth depends upon the presence of fats, and sebum, which you will recall is present in hair roots.

Relevant Testing

Pickers and pullers may benefit from an essential fatty acid (EFA) analysis, particularly looking for elevated arachidonic acid and suppressed dihomo-gamma linoleic acid;  These  could contribute to a number of conditions such as irregular hormone production, insulin instability and prostaglandin problems.

Our research at Trichotillomania Support UK reveals that many women experience worsening symptoms of trichotillomania during ovulation, which is also often delayed.  it is very likely that a sebum/malassezia imbalance is the cause, as ovulation affects EFA conversion to prostaglandins. To balance prostaglandin-to-estrogen ratio, a wild yam cream (progesterone cream) could be used on the skin prior to ovulation.  Keep thorough records of your menstrual cycle and your pulling or picking.  Apply the cream one or two days before ovulation, around the time when your estrogen levels should begin to decline and progesterone levels increase.


Evening Primrose oil supplementation may help, because it is rich in GLA, which would be low in the case of delta 6 desaturase deficiency.  Consider eating tahini or whole sesame seeds, as these may help prevent over-action of delta 5 desaturase.

To give the body what it needs to make delta 6 desaturase, a diet rich in magnesium, zinc, and vitamin B6.  Avoid high-oleic acid oils on your skin, such as olive oil and jojoba.  Coconut oil is also a high oleic acid but may be ok as it is also high in lauric acid.

Take a good  probiotic daily. 


Try a liquid probiotic scalp treatment, such as a goats milk kefir scalp rinse


For those of you who enjoy home made solutions, search online for a goats milk soap or shampoo recipe.  This old remedy for psoriasis/eczema is based on fact.  Goats milk is high in lauric acid, which has potent anti-fungal properties: Use sesame oil instead of olive oil, and add some chamomile, and/or other anti-fungal herbs in the infusion. Cloves/clove essential oil also have an anaesthetic effect that might help with the itching or more subtle sensations that feed the urge to pull or pick. Use cloves with caution – and please don’t get the mixture in the eyes!

  1. Good morning, Chelsea! My name is Jeanette Johnson. I’ve had to put my fascinated obsession with delta-6 desaturase deficiency and malassezia on the back burner for over five years, but after a lively discussion about the subject with my sister’s vet yesterday (I brought my “fur nephew” in for a malassezia infected ear), I realized it was a passion that I need to get back to. Imagine my surprise to follow a Google hit and randomly find my article hyperlinked and quoted! I hope some of the advice has been helpful to someone living with trichotillomania.
