The basics

Understanding Dandruff

Dandruff is a common scalp condition that causes white or yellow flakes and, often, an itchy scalp. It's linked to a yeast that naturally lives on everyone's skin and to how sensitively each person's scalp reacts to it, and it tends to flare with cold, dry weather, stress, and harsh or fragranced hair products.

It isn't contagious, and it isn't a sign of poor hygiene. It tends to come and go, and what helps is a little different for everyone. For many people, a gentle, consistent hair care routine is easier on the scalp than switching products every few weeks.

Stripping ingredients like SLS, harsh detergents, and fragrance can pull too much oil from the scalp, which sometimes triggers a rebound of even more oil and flaking. Glycerin is a gentle humectant that can help rebalance scalp moisture instead.

Most dandruff responds well to a gentler routine over a few weeks. Flaking that's heavy, spreads to the face or ears, or comes with a red, painful, or weeping scalp is worth a dermatologist visit; it could be seborrheic dermatitis, psoriasis, or another condition.

Cleure hair care is fragrance-free, dye-free, and sulfate-free, and formulated without common irritants, so your scalp has less to react to. Our shampoo and conditioner carry the National Eczema Association Seal of Acceptance.

The triggers

What to know about Dandruff

Common triggers

A common scalp yeast (Malassezia) that everyone has, and how sensitively your scalp reacts to it
Fragrance in shampoo, conditioner, and styling products
Sulfates (SLS) and other harsh, stripping cleansers
Going too long between washes, which lets oil and flakes build up
Heavy oils and pomades left sitting on the scalp
Cold, dry weather and indoor heating
Stress and lack of sleep

What it can look like

White or yellowish flakes in your hair or on dark clothing
An itchy scalp, often worse a day or two after washing
A dry, tight, or slightly greasy-feeling scalp
Mild redness along the hairline or behind the ears
Flakes that ease up and come back, often worse in winter

What helps day to day

Use one gentle, fragrance-free shampoo and conditioner consistently, rather than switching products every few weeks
Choose fragrance-free everything that touches your scalp, including styling products
Massage shampoo in with your fingertips, not your nails, and rinse thoroughly
Wash often enough that oil and flakes don't build up; skipping washes can make flaking worse
Use lukewarm water; hot water can leave the scalp drier and itchier
Talk with your dermatologist if flakes stick around; a medicated shampoo may help, and many people alternate it with a gentle one

Frequently asked questions

Dandruff Questions, Answered

What causes dandruff?

Dandruff is usually linked to a yeast called Malassezia that lives on everyone's scalp, and to how sensitively your scalp reacts to it. Cold, dry weather, stress, and harsh or fragranced hair products commonly make it worse.

Is dandruff contagious?

No. Dandruff isn't contagious and isn't caused by anyone else's scalp or hair. It comes from your own scalp's reaction to a yeast everyone already has.

Is dandruff a sign of poor hygiene?

No. Dandruff isn't caused by being unclean. It's tied to scalp sensitivity and product choice, and washing more or less often doesn't fix it on its own.

Is dandruff the same as a dry scalp?

Not exactly. Dandruff often comes with oilier flaking and mild redness, while a plain dry scalp tends to flake without excess oil. The two can look similar and sometimes overlap.

Does washing my hair less help dandruff?

Usually not. Skipping washes lets oil and flakes build up, and harsh detergents that over-strip the scalp can trigger a rebound of even more oil and flaking. A gentle shampoo used consistently tends to help more.

What ingredients should I avoid if I have dandruff?

SLS, fragrance, and other harsh detergents can all worsen the flaking, dryness, and redness of dandruff. Look for gentle, fragrance-free formulas instead.

Is Cleure shampoo a dandruff shampoo?

No, it isn't a medicated shampoo. It's formulated without fragrance, dyes, or sulfates, and our shampoo and conditioner carry the National Eczema Association Seal of Acceptance. If flakes stick around, a dermatologist may suggest a medicated shampoo, and some people alternate it with a gentle one.

When should I see a dermatologist about dandruff?

See a dermatologist if flaking is heavy, spreads to your face or ears, or your scalp becomes red, painful, or weeping. It could be seborrheic dermatitis, psoriasis, or another condition that needs a different approach.
