Quick answer: a scalp scrub is worth using if you have product build-up, an oily scalp or roots that go flat quickly. Used once a week before shampooing, it lifts away dead skin, oil and residue so your scalp feels fresh and your shampoo works better. Skip it if your scalp is red, sore, broken or very sensitive.
What is a scalp scrub?
A scalp scrub is an exfoliating treatment for the scalp. Just like a face or body scrub, it uses fine granules or clays to lift away dead skin cells, excess oil and build-up from dry shampoo, styling products and hard water.
Do you need a scalp scrub?
You might benefit if:
- your roots get oily quickly after washing;
- you use a lot of dry shampoo or styling products;
- your hair feels heavy, flat or coated even after washing;
- your scalp feels congested or itchy from build-up.
You probably don't need one, or should hold off, if your scalp is sensitive, red, sore or broken, or if you have a diagnosed scalp condition. For a sensitive scalp, choose soothing care instead, such as the Lenitive range.
How to use a scalp scrub
Insight's Scalp Exfoliating Cream is designed as a weekly scalp reset:
- Apply to a dry scalp, section by section.
- Massage gently with your fingertips.
- Leave for 2 to 3 minutes.
- Rinse, then shampoo as normal.
It combines kaolin clay and pine granules to lift away oil and residue, with microalgae, lavender, sage and a cooling touch of menthol for a fresh, clean feel.
What to use after a scalp scrub
- Oily scalp: Rebalancing Shampoo keeps roots fresher for longer. See the oily scalp edit.
- Dandruff-prone scalp: Purifying Shampoo and Purifying Scalp Treatment.
- Fine, flat hair: Volume Up Shampoo for lift from the root.

Frequently asked questions
How often should you exfoliate your scalp?
Once a week is a good starting point. If your scalp feels tight or irritated, scrub less often.
Do you use a scalp scrub before or after shampoo?
Before. Apply Scalp Exfoliating Cream to a dry scalp, rinse, then shampoo.
Does a scalp scrub help hair grow?
A scalp scrub cleanses and refreshes the scalp. It isn't a hair growth treatment. If you're worried about thinning or hair loss, speak to your GP or a trichologist.
Can a scalp scrub help dandruff?
It can lift loose flakes, but it won't replace an anti-dandruff routine. Read our guide to dandruff: causes and treatment.
What is scalp build-up, and how do I get rid of it?
Scalp build-up is a layer of oil, dead skin and residue from dry shampoo, styling products and hard water. It can leave roots looking flat or greasy soon after washing, and the scalp feeling coated or itchy. A weekly scalp scrub before shampooing lifts it away. For a full weekly reset, try our at-home head spa ritual.
Is a scalp scrub the same as a clarifying shampoo?
No. A clarifying shampoo deep-cleans in the wash. A scrub physically exfoliates before you shampoo. Some people use both on the same day for a really thorough reset.
