For anyone with dandruff: visible flakes, itching or redness on the scalp. Biolage lists it for dandruff-prone scalps and hair from fine to thick.

Because it contains a medicinal anti-dandruff ingredient, anyone with a scalp condition that worsens or does not improve with regular use should see a doctor or pharmacist.

Many medicated dandruff shampoos treat the flakes but leave hair rough and the scalp tight. This one combines pyrithione zinc with the Scalp Sync balancing concentrate of fermented tea and glycolic acid, so it tackles flaking and itch while still leaving hair soft and the scalp comfortable.

It sits in a full routine: Purifying Scalp Concentrate as a pre-wash, this shampoo to cleanse, and Universal Conditioner to finish.

Apply to wet hair and massage into a lather, working it onto the scalp.

Rinse thoroughly.

Use regularly to control dandruff. Avoid contact with the eyes; if contact occurs, rinse well with water. Stop use and ask a doctor if the condition worsens or does not improve with regular use.

Pros:

• Pyrithione zinc targets dandruff flaking and itch
• Glycolic acid helps clear flakes and buildup from the scalp
• Menthol and peppermint give a fresh, cool feel
• Regulated anti-dandruff product in Canada (DIN on the label)

Cons:

• Sulfate cleansers may be too much for a very dry or sensitive scalp without dandruff
• Needs regular use to keep dandruff under control
• Contains dimethicone, although Biolage's page describes the range as silicone-free
• Avoid contact with the eyes
