Herbal Treatments For Dandruff: Brilliant or Bogus?

Herbal treatments for dandruff:
can you go all natural?
Normally I want to talk to you about hair accessories, naturally. But I was stuck on a plane earlier this week and against my better judgement started reading a small article in a British broadsheet newspaper about how you could make a tincture to help with dandruff.

As usual, I was left smacking my forehead, wondering how these things get published in newspapers. I thought journalists had to do fact checking? I guess not.

The article outlining this recipe, to be fair, did not claim to cure dandruff (though the headline did).

What I think the recipe was really for was a sort of smelly moisturising balm that would pretty much lose any effectiveness as you had to wash it out TWICE after half an hour. Well, that was a waste of an afternoon, then.

What causes dandruff?

There are two broad types of "dandruff" conditions, where the skin is irritated, itchy and flaky: dermatitis and psoriasis.

Dermatitis
Scientists generally believe dermatitis, or if your head is oily, seborrhoeic dermatitis, is caused by a type of yeast or fungus from the Malassezia family that feeds off the sebum in your scalp.

The fungus is pretty hardy and rubbing random herbs or other natural things found in your refrigerator with supposed antibacterial qualities on it in the hope of making it go away is no good at all.

The yeast feeds on fat, so using an oil-based natural, herbal tincture to try and battle your infection is pretty hopeless.

All main brand dandruff shampoos (such as Head and Shoulders or Nizoral) use tested antifungal ingredients which kill the fungus.

The two most common anitfungal agents used are pyrithione zinc (used in Head and Shoulders) and ketoconazole (used in Nizoral). These agents target different types of Malassezia yeast, so if one brand doesn't work for you, try using the other to see if you get a better result.

Tea Tree oil (melaleuca) has also shown some effectiveness in killing a range of types of yeast, however, there are to my knowlege no commercial shampoos with enough of the extract to really be effective. A lot of the references to tea tree oil I've seen to date on shampoo bottles are pure marketing fluff.

You can purchase pure tea tree essential oil, however it is poisonous and should not be swallowed. Using tea tree oil on your skin can cause severe skin irritation including rash and blistering. Harsh stuff for a natural cure. You have been warned.

Psoriasis
This condition is less common and completely different from dermatitis. Usually there are well-defined, hard silvery patches or plaques. These can often be ring shaped and red at the edge. The flakes sometimes come away in large sheets.

Psoriasis isn't very well understood. Current thinking is that it is caused by an auto-immune disorder, and groups of skin cells just start rapidly reproducing.

There is no cure, but the two most favoured treatments are coal tar extract and UV (ultra violet light) treatment for more intractable cases.

Coal tar extract works by slowing down the production of skin cells. Shampoos such as T-Gel or lotions such as Exorex are available without a prescription at most chemists and can be effective for many people. If your condition doesn't respond to these treatments, you can be eligible for light, or phototherapy, treatment on the NHS.

There are considerable side effects to phototherapy as the UV exposure can rapidly damage and age your skin, so do give the shampoos and lotions a good chance first.

Again, given that the condition is related to your immune system being out of whack, rubbing some herbs in your hair is honestly not going to help one bit.  

Phew. I'm glad I got that all off my chest. At least until I come across another screwy cure for dandruff ...

Rush thyself to Stone Bridge where we've got some nice hair clips, but no cure for dandruff

  1. Hmmm... yes I'm always dubious of 'cure all' tinctures that you can whip up from the out-of-date ingredients in the back of your pantry cupboard! If only life was that simple! :)

    1. Lovely to hear from you Dorset Finca! I do love it when you can solve a problem without buying something in a bottle, but even I have to admit that in this case science has the upper hand! :)
