Irritated scalp and dandruff: our top-rated products, approved by our experts

Dandruff and irritation are two linked and inseparable conditions found on most problem scalps. It usually all stems from an imbalance in the scalp’s microbiome, often favouring the Malassezia yeast. This yeast, by feeding on lipids found on the scalp, releases substances that can cause discomfort. Although most information aimed at the general public focuses on Malassezia, it is important to note that it is primarily the overall dynamics between the microorganisms colonising the scalp that influence the occurrence of dandruff (1).

Disruption of this surface ecosystem, for its part, is promoted by endogenous or exogenous factors such as:

• An unsuitable routine: the use of certain ingredients or cosmetics (particularly those containing surfactants, such as shampoos) can weaken the skin barrier and create conditions conducive to the development of dandruff

• Excess sebum: The sebaceous glands produce more oil in response to hormonal changes, for example during puberty. It may also be a rebound effect following the application of irritating substances or exposure to external aggressors (sun, wind, cold, etc.)

• Genetics: certain individual factors, such as the lipid composition of sebum, can create conditions conducive to the development of dandruff. Our genetic makeup therefore plays a key role. Age also appears to be a determining factor, particularly as physiological skin ageing tends to weaken the skin barrier (1).

“Itchy scalp. I usually use this natural gel as a mask to moisturise and soothe my sensitive skin. That gave me the idea to use it when I had an irritated scalp, with spots, which was itching terribly (due to a hormonal imbalance). I applied a thin layer as a mask to my scalp, gave it a gentle massage and left it on for about 20 minutes before shampooing, once a week for three weeks. My scalp has returned to normal – no more spots, no more itching – and it’s been like this for three months now: incredible!” about organic native aloe vera gel

"Tried and tested. I was suffering from itching and dandruff, which led to severe hair loss. I mixed 2 tablespoons of Tulsi powder, 2 of Bhringaraj and 1 of Neem with mustard oil, grapefruit oil, Atlas cedar oil, provitamin B5 and silk protein to make a mask. My hair is silky and soft, and the dandruff has almost completely disappeared after just two masks. Thank you for all the comments that helped me develop this mask – I’m delighted with it, and so is my hair!” About organic Tulsi powder

"Used in combination with a sulphate-free shampoo, 10 drops of Algo’Zinc and 5 drops of tea tree oil with every wash have cleared up my seborrhoeic dermatitis. I’ve gone from having large patches of dandruff lined up along my hairline, at the top of my forehead, to… absolutely nothing! No more itching, no more flaking for months. Thank you!” about the cosmetic active ingredient Algo’Zinc

A word from our naturopath

Although they can be a nuisance, dandruff and the resulting discomfort are actually valuable indicators. They tell us that something is wrong, that the system is out of balance and that our body is facing biological stress that it is struggling to overcome. Dandruff is merely a consequence: the best way to get rid of it once and for all is to tackle its cause(s). At the same time, you can adopt an anti-inflammatory diet to support a good topical skincare routine. To do this, it is advisable to limit your intake of dairy products, processed foods and foods with a high glycaemic index.

Lou Dumas, Naturopath

A word from our dermatologist

Dandruff and the resulting irritation are primarily caused by excessive sebum secretion. It is important to bear this in mind when choosing which products to apply to the scalp, particularly vegetable oils. Oil treatments left on the roots for too long, for example, can have the opposite effect to that intended by stimulating the growth of lipophilic yeasts. Although certain vegetable oils can be helpful in relieving occasional discomfort, it is best to strictly limit the duration of application. Lauric and oleic acids remain the most problematic when it comes to Malassezia. It is therefore wisest to avoid olive oil (which is actually used as a culture medium in tests on Malassezia) or coconut oil, to name but a few.

Dr Agathe Aoun, Dermatologist

Scalps prone to dandruff or irritation should be regarded as sensitive and reactive. They essentially need gentleness and stability. Therefore, remember to test a new product on a small area of skin before incorporating it into your routine. Also, be sure to follow the recommendations and dosages indicated on our product information sheets. When suffering from stubborn dandruff, it is sometimes tempting to use multiple active ingredients in the hope of finding a radical solution. We advise against giving in to this temptation. Anti-dandruff active ingredients are generally potent: using several at once or layering them risks weakening your skin barrier. Consequently, you risk creating a vicious circle that will increase your feelings of irritation and encourage the development of new dandruff. If your irritation and dandruff problems worsen despite your efforts with skincare products (sores, scabs, etc.), we recommend that you consult a dermatologist.
