Exfoliate the scalp when it feels coated or the roots look heavy soon after washing, not as a daily habit. Once a week is a sensible place to begin, and once a fortnight is often enough for fine hair or a scalp that is easily unsettled. Choose a scrub if you like to feel the cleanse, an exfoliating shampoo if you prefer a smooth wash, and a scalp mask when you want a slower step. Massage with the fingertips, rinse for longer than seems necessary, and follow with a light scalp serum if you use one. Below is each step, and the scalp care we would choose for it.
Why Exfoliate the Scalp?
The scalp is skin. Like the skin on your face, it renews its surface continually, while sebum, sweat, dry shampoo and styling products gather at the root. Ordinary shampoo lifts most of this. Over a week or two, a little can stay behind, and the scalp may feel less fresh soon after washing. Exfoliating is an occasional, deeper clean of that surface. If your scalp already feels comfortable and clean, it may not need it at all.
If oil at the root is your main concern, our routine in Oily Hair: Why It Happens and a Routine That Balances It covers everyday washing; exfoliation sits alongside it as the weekly step.
Scrub, Exfoliating Shampoo or Scalp Mask?
Three kinds of product do this work, each in its own way.
- A scalp scrub uses fine grains, often salt, that you massage over the scalp. You feel it working, and the grains rinse away.
- An exfoliating shampoo uses acids, such as AHAs or salicylic acid, which loosen surface build-up as you wash. The texture is smooth, and the step fits into an ordinary wash day.
- A scalp mask, often made with clay, is left on for a few minutes and rinsed. Clays such as kaolin and bentonite are valued for absorbing oil. Some are used before shampoo, others after.
Some exfoliating products come as liquids or serums that are applied to the scalp and left briefly before washing; follow the pack for timing. Whichever you choose, use one exfoliating product on a given day rather than a scrub, an acid wash and a mask together.
Scrubs and Exfoliating Shampoos
Phyto's Scalp Solution Purifying Cleansing Scrub brings together salt and eucalyptus oil in a scrub made for all scalp types, presented as a targeted treatment rather than a daily shampoo. Christophe Robin's Detox Ritual Cleansing Purifying Scrub uses marine salt, with bisabolol and sweet almond oil in the formula; the house suggests it once a week or after colouring, followed by conditioner.
For a smoother wash, Rated Green's Real Mary Cold Brew Rosemary Exfoliating Scalp Shampoo pairs rosemary with ginger and peppermint, and combines salicylic acid with a mechanical exfoliating action. L'Oréal Professionnel Paris's Scalp Advanced AHA 3% Dermo-Purifier Shampoo is made for oily scalps, with 3% AHA, for a scalp that feels fresher and lengths that stay light.

How Often Should You Exfoliate the Scalp?
Begin with once a week and watch how your scalp responds. If it feels fresh for longer, you have the rhythm. If it feels tight or sensitive, move to once a fortnight. A scrub is never a daily step. An exfoliating shampoo may be designed for more regular use, so follow what its pack says rather than a general rule. Leave exfoliation out on any day your scalp feels tender, and never work a scrub over scratches or broken skin.
Acids deserve a little extra care. Try a new acid product on a small area first, and keep it away from the eyes. Exfoliated skin can be more sensitive to the sun, so cover your parting on bright days.
How to Massage It In
- Wet the hair thoroughly with lukewarm water, so the product spreads easily.
- Part the hair into four or five sections and apply a small amount directly to the scalp along each parting.
- Use the pads of your fingertips, never the nails, in small, slow circles.
- Keep the pressure light: the grains or acids do the work, not force.
- Spend a minute or two, working from the hairline back to the nape and behind the ears.
Rinse Longer Than You Think
Grains and clay settle at the root, where they are easy to miss. Rinse with lukewarm water, lifting the hair with your fingers so the water reaches the scalp, until it feels clean and nothing gritty remains. If the product is a pre-wash step, shampoo afterwards as usual. Finish with conditioner on the lengths and ends only, away from the freshly cleansed scalp.
Scalp Masks
Revlon's Re/Start Balance Clay Scalp Mask is made with kaolin and bentonite, applied to the scalp, left briefly and rinsed away, in a small tube that suits an occasional step. Rene Furterer's Astera Head Spa Soothing Pre-Shampoo Hair Treatment comes in single-use ampoules with mint and eucalyptus oils for a cooling feel; it is applied to the scalp section by section before shampoo, massaged in gently and left briefly. Wella Professionals' Invigo Scalp Balance Sensitive Scalp Hair Mask works the other way round: it goes onto a clean, damp scalp after washing. It is fragrance-free, made with allantoin and designed for sensitive scalps.

A Scalp Serum After Washing
A freshly cleansed scalp is the right moment for a leave-in step. Apply a scalp serum to towel-dried hair along the partings, massage it in with the fingertips and style as usual. Guerlain's Abeille Royale Scalp & Hair Youth Oil-In-Serum combines honey and royal jelly with panthenol and zinc PCA in a light texture, applied with a dropper to the scalp and lengths. Living Proof's Dry Scalp Microbiome Balancing Treatment is a lightweight gel for a dry scalp, with niacinamide and sodium hyaluronate, left in. Wedo's Scalp Refresh Refreshing Scalp Tonic is a leave-in tonic with bamboo extract, for towel-dried or dry hair. Cantu's Guava Scalp Nourishing Treatment Serum is made for curls, coils and waves, with guava, ginger, carrot seed oil and tea tree oil.

The Routine at a Glance
- Once a week to begin, once a fortnight if your scalp prefers it.
- One exfoliating product a day: a scrub, an exfoliating shampoo or a scalp mask.
- Apply in sections and massage with the fingertips for a minute or two.
- Rinse until nothing remains, then shampoo if the step was pre-wash.
- Conditioner on the lengths only, then a scalp serum on the scalp if you use one.
When to Ask for Advice
Exfoliation is cosmetic care for a scalp that is otherwise comfortable. If your scalp is itchy, flaking or sore, or you notice hair loss, ask a pharmacist or doctor before you add an exfoliating step. Introduce one new product at a time, so you can see what your scalp responds to.
If you change only one thing this week, make it the rinse: give it an extra minute, with the water reaching the scalp itself.
