TL;DR: Dandruff is caused by an overgrowth of Malassezia yeast feeding on scalp oil — not by dry skin. To fix it, you need a shampoo with a proven antifungal active (piroctone olamine or zinc pyrithione) plus an exfoliant (salicylic or glycolic acid) to clear existing flakes. Leave it on for 2–3 minutes before rinsing, use it 2–3 times a week, and expect visible improvement within two to four weeks. Below: the exact products our stylists reach for, matched to your scalp type.
What Dandruff Actually Is (and the Myth That Makes It Worse)
The biggest misconception we hear in our salons: "My scalp is flaking, so it must be dry — I'll skip washing and add oil." This usually makes dandruff worse. Classic dandruff is driven by Malassezia, a yeast that lives on everyone's scalp and feeds on sebum (your natural scalp oil). When it overgrows, it irritates the skin and speeds up cell turnover — skin cells that should shed invisibly over a month instead pile up and shed in visible clumps within days. That's the flaking you see on dark shirts.
Because the yeast feeds on oil, washing less and applying oils gives it more food. Oily scalps flake more, not less. The fix isn't moisture — it's controlling the yeast and clearing the build-up.
The Actives That Actually Work
Ignore the marketing on the front of the bottle and check for these on the back:
Piroctone olamine — a modern antifungal that reduces Malassezia proliferation and slows the accelerated cell turnover that creates flakes. Gentler on sensitive scalps than older actives, and the hero ingredient in Kérastase's Symbiose range.
Zinc pyrithione — the classic, heavily researched anti-dandruff active. It's antifungal and antibacterial, calms inflammation and helps regulate sebum — important because sebum is exactly what the yeast feeds on.
Salicylic acid — an exfoliant rather than an antifungal. It dissolves the bonds holding dead skin together, lifting existing flakes and build-up off the scalp so the antifungal can do its work. The best formulas pair an antifungal with an exfoliant.
Glycolic acid — another exfoliant, used in DS Laboratories' Dandrene to clear dead cells and flakes while zinc pyrithione handles the yeast.
The Best Anti-Dandruff Shampoos in South Africa, by Scalp Type
Oily, sensitive scalp: Kérastase Symbiose Bain Pureté
Kérastase Symbiose Bain Pureté Anti-Pelliculaire 250ml is the luxury benchmark for oily dandruff. Sulphate-free and silicone-free, it combines piroctone olamine with salicylic acid to exfoliate visible flakes instantly, deep-cleanse pores clogged with sebum and dead cells, and calm itching — with up to 7 weeks of anti-dandruff efficacy with continued use. If your roots get greasy within a day and flakes cling to them, start here.
Dry, sensitive scalp: Kérastase Symbiose Bain Crème
Kérastase Symbiose Bain Crème Anti-Pelliculaire 250ml uses the same piroctone olamine + salicylic acid pairing in a creamy, hydrating base with squalane. Same anti-dandruff power, but built for scalps that feel tight, itchy and uncomfortable rather than greasy. If your flakes are fine and powdery and your scalp feels parched, this is your version.
Stubborn or chronic flaking: DS Laboratories Dandrene
DS Laboratories Dandrene Anti-Dandruff Shampoo 205ml is the clinical heavyweight — a dermatologist-recommended formula built around zinc pyrithione with glycolic acid to exfoliate, delivered via DS Labs' nanosome technology for prolonged action after rinsing. It targets dandruff as well as flaking associated with seborrheic dermatitis. Pair it with the Dandrene Anti-Dandruff Conditioner — most conditioners simply re-coat the scalp, but this one continues the zinc pyrithione treatment while keratin and aloe keep lengths soft.
Everyday maintenance: Goldwell Dualsenses Scalp Specialist
Goldwell Dualsenses Scalp Specialist Anti-Dandruff Shampoo 250ml is the dependable salon-floor option for mild to moderate flaking — effective, well-priced and gentle enough for frequent use. There's also a dedicated Goldwell Dualsenses Mens Anti-Dandruff Shampoo 300ml for shorter hair that gets washed daily.
Value picks for men: MUK and Depot
MUK Head Muk Dandruff Control Shampoo 300ml handles flake control without fuss, while DEPOT 102 Anti-Dandruff Sebum Control Shampoo 250ml doubles down on oil regulation — a smart pick if greasy roots and flakes arrive together.
How to Use an Anti-Dandruff Shampoo Properly
Most people who say "anti-dandruff shampoos don't work for me" are rinsing too soon. The actives need contact time with the scalp:
1. Focus on the scalp, not the lengths. Massage the shampoo into the roots — that's where the problem lives.
2. Leave it for 2–3 minutes. Wash your body, then come back and rinse. This single change makes the biggest difference.
3. Use it 2–3 times a week. On other wash days, alternate with your regular shampoo so lengths don't dry out.
4. Don't stop the moment flakes disappear. The yeast returns when treatment stops. Step down to once a week for maintenance rather than quitting entirely.
Judy, our head trainer at Partners Hair, puts it simply: "Treat an anti-dandruff shampoo like a scalp treatment, not a shampoo. Apply it first, let it sit while you finish the rest of your shower, and rinse it last. Clients who do that see results in two weeks. Clients who lather and rinse in twenty seconds tell me the product failed."
When It's Not Dandruff
If flaking comes with thick yellow scales, raw or weeping patches, defined silvery plaques, or flaking through eyebrows and around the nose, you may be dealing with seborrheic dermatitis, psoriasis or eczema — and a GP or dermatologist should look at it. Anti-dandruff shampoos can support treatment, but they won't replace it. The same applies if a quality anti-dandruff shampoo used correctly for six weeks changes nothing.
Frequently Asked Questions
Does dandruff mean my scalp is dry?
Usually the opposite. Classic dandruff thrives on oily scalps because the yeast that causes it feeds on sebum. A genuinely dry, flaky scalp produces fine, powdery flakes — in that case choose the hydrating route (Symbiose Bain Crème) rather than adding oils, which feed the yeast.
Can I use anti-dandruff shampoo on coloured hair?
Yes — choose wisely. Kérastase Symbiose is sulphate-free and respects the hair fibre, and Dandrene is colour-safe. Apply to the scalp only and keep it off your lengths as much as possible.
How long before I see results?
With correct use (contact time, 2–3 times weekly), itching usually settles within the first week and visible flaking improves within two to four weeks. Kérastase claims up to 7 weeks of efficacy with the Symbiose system used consistently.
Will washing my hair less help?
No — this is the most common mistake we see. Less washing means more sebum, which means more food for the yeast. Keep washing regularly; just make sure one of those washes uses a proper anti-dandruff formula.
