01 / Start with the scalp
Dry scalp and dandruff can look similar.
Both may involve flakes and itch. Dry skin can be linked to moisture loss or a routine that feels too harsh. Dandruff has several possible contributors, including oily skin and certain skin conditions. Appearance alone may not tell you the cause.
If dryness is your main concern
A gentle, non-medicated shampoo may be a better starting point for ordinary dry scalp. Read our shampoo for dry scalp guide before choosing a stronger cleansing routine.
If flakes persist or recur
An anti-dandruff shampoo may be appropriate for mild dandruff. Check the active ingredient and follow the product label. If symptoms persist or worsen, seek professional advice.
This guide helps you compare product labels. It cannot diagnose the reason for flaking or itching.
02 / Product label
How to choose a shampoo for dandruff
Look for a product specifically labeled for dandruff and check its active ingredient. The NHS lists ketoconazole, coal tar and salicylic acid among ingredients found in anti-dandruff shampoos. The American Academy of Dermatology also discusses other active ingredients. Availability and product instructions vary by country.

The ingredient list is a comparison aid, not a ranking. A cosmetic shampoo without a dandruff indication should not be presented as a treatment simply because it feels soothing or contains a popular scalp ingredient.
- Read the directions. Apply to the scalp as instructed and check whether the label specifies a contact time.
- Account for your hair type. Washing frequency and use of medicated shampoo can differ for straight, curly or coily hair.
- Review your response. A pharmacist can help with product selection and use. Avoid assuming every kind of flaking needs the same product.
03 / When to get help
Know when a shampoo is not enough.
See a healthcare professional if your scalp is red or swollen, very itchy, painful, or if flaky patches also appear on your face or elsewhere. The NHS also advises seeing a GP when dandruff symptoms remain after at least four weeks of anti-dandruff shampoo use.
Other scalp conditions can resemble dandruff. A clinician can assess the cause when symptoms are persistent or severe.
04 / Next step
Match your routine to the actual concern.
If ordinary dryness seems more likely, compare gentle cleansing in the dry scalp guide. For a broader view of oily, sensitive, fine or damaged hair needs, use the shampoo and scalp guide.
