Twenty bottles say "anti-dandruff" and the prices vary fivefold. The difference between them is not the packaging — it is two or three lines in the ingredient list. Learn the best anti-dandruff shampoo ingredients and you can choose in under a minute.
The five that have a mechanism
- Zinc pyrithione — antifungal and mildly anti-inflammatory. The sensible default first try.
- Climbazole — antifungal, gentler in feel, good if your scalp is easily irritated.
- Ketoconazole — the strongest of the common antifungals; where to go when stubborn flaking has not budged.
- Salicylic acid — an exfoliant rather than an antifungal. It lifts thick, adherent scale so the other actives can reach skin.
- Selenium sulphide — slows cell turnover and fungal growth; suits oilier, heavier flaking.
On zinc pyrithione vs ketoconazole: start with zinc, since it is milder and cheaper, and move to ketoconazole if a month brings no change.
The tell for a fake
If the front says anti-dandruff and the ingredient list is botanical extracts plus menthol, you have bought a pleasant cooling sensation. Tingle is not efficacy.
How to use dandruff shampoo
Most failures are application failures, not product failures.
- Work the lather into the scalp, not the lengths.
- Leave it on three to five minutes. This is non-negotiable — the active needs contact time.
- Rinse thoroughly. If your hair now feels rough, follow with a mild shampoo on the lengths.
- Conditioner on the lengths only, well clear of the roots.
- Two or three washes a week for the first month, then once a week to maintain.
Rotate before it fails
A common complaint is that a dandruff shampoo stopped working after a couple of months. Keep two bottles with different actives and swap them every four to six weeks, using an ordinary mild shampoo in between.
Where a shampoo will not get you
Medicated shampoo addresses the ordinary case. It is the wrong tool when:
- The flakes are small, dry and powdery — that is a dry scalp, and drying it further backfires
- There are red patches, crusts or weeping skin
- Flaking has spread to eyebrows, face or chest
- Flaking comes alongside noticeable shedding
In those cases see a doctor or trichologist. Seborrhoeic dermatitis and psoriasis both present as "dandruff" and need prescription treatment, and significant hair loss deserves medical assessment in its own right.
Faberlic stocks anti-dandruff shampoos alongside mild everyday formulas suitable for rotation; see the current catalogue on faberlic.com, which refreshes roughly every three weeks. For scalp care in the wider routine, see the haircare guide.
