What are the main causes of dandruff?

Dandruff is caused by several factors, including an imbalance in the scalp microbiome, excess sebum, and the presence of a microscopic fungus called Malassezia. These factors create an environment conducive to excessive desquamation, leading to visible dandruff. An inflammatory reaction can also aggravate the problem, making the scalp irritated and inflamed.

What treatments are recommended for dandruff?

Treatment for dandruff can vary according to intensity and underlying cause, but it's often advisable to start with specific anti-dandruff shampoos. These products contain active ingredients such as pyrithione zinc, selenium sulfide or salicylic acid, which help control sebum and inhibit fungal growth. We recommend using these shampoos regularly, following the instructions for best results.

How can dandruff be prevented?

Preventing dandruff involves a proper hair care routine that includes the use of gentle, moisturizing products to maintain scalp balance. Avoiding irritating styling products and excessive washing can also help reduce the risk. A healthy lifestyle, including a balanced diet rich in B vitamins, zinc and omega-3 fatty acids, is crucial to maintaining scalp health.

What natural remedies can help treat dandruff?

Several natural remedies can be used to treat dandruff effectively. Tea tree oil, renowned for its antifungal and antibacterial properties, can be added to shampoo or used as a direct treatment. Cider vinegar is another popular remedy, restoring the scalp's pH and preventing excessive fungal growth. Applying aloe vera can also help soothe and moisturize an irritated scalp.

When should I consult a professional about dandruff problems?

It is advisable to consult a dermatologist if dandruff persists despite regular use of anti-dandruff treatments, or if it is accompanied by redness, irritation or hair loss. A healthcare professional can assess your condition to rule out other dermatological problems such as psoriasis or seborrheic dermatitis, and suggest a suitable treatment.

What's the difference between dry and oily dandruff?

Dry dandruff is characterized by small white flakes that fall easily from the scalp. It is often caused by dry ambient air, central heating or excessive washing of the hair, which eliminates the natural oils. Oily dandruff, on the other hand, is caused by excess sebum, and manifests itself as larger flakes that stick to the scalp and hair. This type of dandruff can also be associated with an unpleasant odor due to bacterial proliferation.

Can essential oils be used to treat dandruff?

Yes, certain essential oils can be beneficial in the treatment of dandruff, thanks to their antifungal and soothing properties. Lavender essential oil, for example, helps regulate sebum production and reduce inflammation. Rosemary essential oil stimulates scalp circulation and has antiseptic properties. It is important to dilute essential oils in a carrier oil, such as jojoba or coconut oil, before application to avoid irritation.

How can dandruff be distinguished from other scalp conditions?

Dandruff can sometimes be confused with other conditions such as seborrheic dermatitis, scalp psoriasis or eczema. Seborrheic dermatitis is characterized by oily patches of skin and oily, yellowish dandruff. Scalp psoriasis presents thick, scaly and often silvery patches.Eczema can cause dry, red, intensely itchy skin. An accurate diagnosis by a dermatologist is crucial for appropriate treatment.

Do seasonal changes affect dandruff?

Yes, seasonal changes can influence the appearance and severity of dandruff. In winter, the lack of humidity in the air and the use of central heating can dry out the scalp and encourage dry dandruff. In summer, higher temperatures and humidity can stimulate sebum production, exacerbating oily dandruff. It's advisable to adapt your hair care routine according to the season to better control symptoms.

What impact does stress have on dandruff?

Stress is a factor that can aggravate dandruff. It affects the immune system and can unbalance hormone levels, increasing sebum production and promoting the proliferation of Malassezia. Managing stress through relaxation techniques, a balanced diet and adequate sleep can help reduce the frequency and intensity of dandruff.
