Trichology · Scalp
White flakes on shoulders, itching, flakes that return a few days after washing hair — dandruff can be stubborn and embarrassing. The catch is that a regular "dandruff" shampoo often washes away the symptom without addressing the cause. In this guide, we explain where dandruff comes from, how to distinguish between dry and oily, what ingredients to look for, and which professional line to choose — DSD de Luxe (Dixidox) or DermoMedica.
Why does dandruff return — and why it's not a matter of "dirty hair"
Dandruff is excessive, visible shedding of the scalp's epidermis. Contrary to popular belief, it does not come from an unwashed head — more often from the opposite. At its root is most often the Malassezia yeast, naturally present on everyone's skin, which under favorable conditions (excess sebum, irritated barrier) proliferates and causes inflammation and accelerated shedding.
That's why a regular "dandruff" shampoo from the drugstore often works briefly: it washes away the flakes but does not address the cause. The symptom disappears for a week and returns. The key is to choose a product for the type of dandruff and to use it as a treatment, not as a regular wash.
Dry or oily dandruff? It changes everything
Before you choose a product, identify the type of problem — because the strategy is different.
| Feature | Dry dandruff | Oily dandruff (seborrheic) |
|---|---|---|
| Flake appearance | Small, white, "flakes off" | Larger, yellowish, oily, adheres |
| Scalp condition | Dry, tight, itchy | Oily, shiny |
| Accompanied by | Dryness, irritation | Oiliness, sometimes redness |
| Direction of action | Moisturizing + gentle antifungal | Regulating sebum + antifungal |
A common mistake is treating oily dandruff with drying shampoos "for oiliness" — the scalp then responds with even stronger oiliness, and the vicious cycle closes. If you're unsure what type it is, it's worth starting with a trichological diagnosis.
What to look for in the ingredients — ingredients that really work
An effective anti-dandruff product should combine antifungal, anti-inflammatory, and normalizing shedding actions. The best-studied ingredients are:
- Piroctone olamine and antifungal derivatives — limit the proliferation of Malassezia yeast at the source of the problem.
- Salicylic acid — dissolves and exfoliates dead flakes, "opens the way" for other ingredients.
- Azelaic acid — has anti-inflammatory and antibacterial properties, well tolerated by sensitive scalps.
- Zinc (zinc pyrithione) — a classic with antifungal and anti-seborrheic action.
- Soothing ingredients (centella, panthenol) — alleviate itching and irritation that often accompany dandruff.
DSD de Luxe (Dixidox) or DermoMedica? Two proven paths
In the J'ADORE INSTYTUT store, there are two professional trichological lines that we most often reach for — and which represent two different approaches.
DSD de Luxe (Dixidox line) is Spanish cabinet trichology with strong, targeted action. It has separate formulations for dandruff (line 2.x), for oiliness (line 1.x), and a peeling to prepare the scalp. This is a "treatment" solution — for a noticeable, persistent problem, best conducted under the supervision of a specialist.
DermoMedica is a Polish brand with a gentler, anti-inflammatory profile — a shampoo-peeling with azelaic acid and a soothing shampoo with centella. This is a good path for people with sensitive, reactive scalps, with milder dandruff, and as daily, caring support between treatments.
| DSD de Luxe / Dixidox | DermoMedica | |
|---|---|---|
| Character | Intensive cabinet treatment | Gentle, anti-inflammatory support |
| Key action | Targeted: dandruff / oiliness / peeling | Azelaic acid, centella — soothing |
| For whom | Persistent, severe dandruff | Sensitive scalp, milder symptoms |
| Best | As part of a protocol with a trichologist | Daily care and maintenance of effect |

How to use to prevent dandruff from returning
The most common reason for relapses is too short and too impatient a method of use. An anti-dandruff product is a treatment — treat it as such.
- Scalp peeling once a week — removes dead flakes and allows the shampoo to work deeper.
- Medicinal shampoo with exposure time — apply, gently massage, and leave on for 3–5 minutes before rinsing. It’s this time that works, not just the rinse.
- Lotion between washes — for a more severe problem, a product left on the skin works when you’re not washing your hair.
- Regularity for several weeks — do not stop after the first improvement; continue the treatment and switch to gentler maintenance when symptoms subside.
- Do not dry out forcefully — too aggressive, frequent washing can intensify both oiliness and irritation.
When to see a specialist and when to see a doctor
If dandruff is severe, recurs despite treatment, is accompanied by intense itching, redness, oozing lesions, or hair loss — it’s a signal that it’s worth performing a trichological diagnosis, and if seborrheic dermatitis or psoriasis is suspected — consult a dermatologist. Dermocosmetics alleviate symptoms and keep the scalp in balance, but do not replace the diagnosis of chronic conditions.

Frequently asked questions
Is dandruff a result of not washing your hair?
No. Dandruff is most often associated with the excessive proliferation of the Malassezia yeast and inflammation of the scalp, not with a lack of hygiene. Paradoxically, too frequent, aggressive washing can intensify irritation and oiliness. The key is to choose the right product for the type of dandruff, not just to wash more often.
DSD de Luxe or DermoMedica — what to choose?
DSD de Luxe (Dixidox line) is an intensive trichological treatment for noticeable, persistent dandruff and oiliness, best conducted under the supervision of a specialist. DermoMedica with azelaic acid and centella is gentler, anti-inflammatory — it works well for sensitive scalps and as daily support. For a more severe problem, it's worth starting with DSD and maintaining the effect with DermoMedica.
How long should you use anti-dandruff shampoo?
Anti-dandruff products are a treatment, not a one-time wash. They are usually used regularly for several weeks, with an exposure time of 3–5 minutes on the scalp, and after symptoms subside, switch to a gentler maintenance. Stopping right after the first improvement is the most common cause of relapses.
Is scalp peeling necessary?
It helps a lot with dandruff. Peeling removes dead skin flakes and remnants of the epidermis, allowing the active ingredients from the shampoo to penetrate deeper and work more effectively. It should be used usually once a week, before washing with a medicinal shampoo.
When does dandruff require a visit to a dermatologist?
When it is severe, persistently recurs despite treatment, is accompanied by intense itching, redness, oozing lesions, or hair loss. Such symptoms may indicate seborrheic dermatitis or psoriasis, which require diagnosis and treatment. Dermocosmetics alleviate symptoms but do not replace the diagnosis of chronic conditions.
