Scalp Care & Dandruff

Is it dandruff or a dry scalp?

Dandruff and a dry scalp look similar, but they're actually opposite problems, and using the wrong hair product can make the flaking worse. Dandruff flakes are larger, slightly yellow and a bit oily, and they stick to your roots. A dry scalp sheds smaller white flakes that fall away easily, and your skin will usually feel tight in other places.

Here's the quickest test. Wash your hair, then check your scalp an hour later. If it feels tight and itchy, it's dryness. Oily roots with flakes still sitting there mean dandruff.

The distinction matters because they're caused by completely different issues. Dandruff happens when a natural scalp yeast called Malassezia feeds on excess oil, which is why it often flares up during a humid Aussie summer. A dry scalp flakes simply because it's lacking moisture. Still, both make your scalp shed skin too fast, so gentle exfoliation helps either way.

Most flaky scalps settle down once you match the product to the cause. If yours sticks around, spreads past your hairline or comes with redness and soreness, book in with your GP. Eczema, psoriasis and seborrhoeic dermatitis all turn up on the scalp, and those need proper treatment rather than a new shampoo.

How does anti-dandruff shampoo work?

Anti-dandruff shampoo works by controlling the yeast behind the flaking, lifting the buildup sitting on your scalp and calming the itch that makes you scratch. Most formulas focus on two of those three jobs, and the active ingredient tells you what you're getting.

Look for these on the label:

• Piroctone olamine: This salon-grade active targets the yeast directly and keeps working between washes rather than just while you rinse. It's gentle enough for regular use and stays kind to colour-treated hair.
• Salicylic acid: This ingredient acts as an exfoliant to loosen stubborn, stuck-down flakes so they wash away instead of collecting at your roots. Because it can dry out your lengths, always follow with a good conditioner.
• Tea tree oil: This natural antifungal provides a cooling finish that helps soothe the scalp. If you prefer plant-derived formulas, Paul Mitchell offers a complete Tea Tree range with shampoos, conditioners and scalp treatments.

How to choose a dandruff shampoo for your scalp type

Match your dandruff shampoo to how your scalp behaves between washes, not to how bad the flaking looks today. Get that right, and you’ll need the shampoo less often.

Finding the right formula comes down to how your scalp feels day to day:

• Flaking with an oily scalp: Go for a purifying formula that clears sebum along with the flakes. An oily scalp feeds the yeast, so cleansing power matters. Opting for anti-dandruff products built around menthol or peppermint gives an immediate cooling hit that takes the edge off the itch.
• Flaking with a dry or tight scalp: You can have dandruff and a dry scalp at once, so reach for a hydrating dandruff formula rather than a purifying one. Stripping a dry scalp harder only worsens the flaking. Look for a product that treats and moisturises in one wash.
• Flaking with a sensitive scalp: Start with a soothing, fragrance-light cleanser and add the treatment formula once your scalp settles. Our stylists recommend alternating the two rather than committing to a strong formula from day one.

How often should you use a dandruff shampoo?

Use a dandruff or itchy scalp shampoo two to three times a week to start, then drop back to once a week once the flaking settles. Daily use is rarely needed and can leave your scalp drier than when you began.

Give it four weeks before you judge whether the product is working. Most people see flaking ease within two weeks, but scalp health rebuilds slowly and the yeast returns if you stop the moment things improve.

Here are three simple habits that make a real difference:

• Alternate your wash days: Alternate your dandruff shampoo with a gentler wash on the days between rather than using it back to back.
• Give it time to act: Leave the lather on your scalp for two to three minutes so the active ingredient has time to work.
• Adjust as needed: Increase how often you wash if flaking returns, then taper back once it settles.

Can you use anti-dandruff shampoo on coloured hair?

Yes, you can definitely use anti-dandruff shampoo on coloured hair, as long as you stick to a sulphate-free formula and check that the label says colour-safe. Salon dandruff shampoos are generally formulated to protect your shade, while stronger clarifying formulas can strip tone faster.

If you have coloured hair, using a moisturising or sulphate-free dandruff shampoo twice weekly sits comfortably alongside your colour routine. Heavy clarifying and detox washes don’t, so save those for the occasional reset.

Building a scalp routine with scrubs, serums and brushes

Treat your scalp much like your face by exfoliating, cleansing, conditioning and treating in that order. Shampoo handles the surface, while the rest of the routine keeps flakes from coming back.

Here's how a weekly routine fits together:

• Step 1: Exfoliate weekly: Work a scalp scrub through before you shampoo. Massage it into a damp scalp in small circles, working from your hairline back. A scalp exfoliator lifts buildup that shampoo alone leaves behind.
• Step 2: Cleanse gently: Wash with your dandruff shampoo, focusing on your scalp rather than your lengths. Be sure to use your fingertips, never your nails, or a tool like our Hairhouse Scalp Stimulating Therapy Brush.
• Step 3: Condition lengths: Next, apply an anti-dandruff conditioner to your mid-lengths and ends, keeping it off the scalp where it can build up.
• Step 4: Treat overnight: On nights between washes, massage an anti-dandruff serum into a towel-dried scalp. Leave-in formulas keep working while you sleep.
• Step 5: Boost hydration: You can also add a weekly mask from our hair treatments range if your lengths feel dry from the switch.

Stick with the routine, and maintaining a healthy scalp usually gets a whole lot easier over time.
