How to exfoliate your scalp: scrub vs serum, and how often
By the exokiss team ·
In short
- Scalp exfoliation lifts away product buildup, oil and dead skin, so the scalp feels fresh and roots look fuller.
- Scrub = physical grains you massage in before shampoo. Serum = a gentle acid (like lactic acid) you apply to a dry scalp before washing.
- Once a week is enough for most people, or as needed.
- Flaking that's itchy, red or persistent may be dandruff or a skin condition: see a dermatologist.
We exfoliate our faces without thinking twice, but the scalp is skin too, and it collects oil, dry shampoo, styling product and hard-water residue. A weekly scalp exfoliation keeps roots light and the scalp feeling clean. Here's how to choose between a scrub and a serum, with products from our hair care.
Scalp scrub vs scalp serum
| Scalp scrub | Exfoliating scalp serum | |
|---|---|---|
| How it works | Fine grains physically lift buildup | A gentle acid loosens buildup |
| Feels like | A massage; tingly, deep-clean feel | Light, no grit |
| Best for | Heavy product use, oily roots | Flat roots, a fragrance-free option |
| When | Before shampoo, as needed | On a dry scalp before washing, once or twice a week |
How to use a scalp scrub
- Section your hair and apply small amounts of scrub directly to the scalp.
- Massage gently with your fingertips for one to two minutes. Don't scratch.
- Rinse, then shampoo, concentrating the lather at the roots.
- Condition your mid-lengths and ends only.
Our Scalp Scrub is a rich pre-shampoo scrub with fine cherry-shell grains and kaolin, plus rosemary, peppermint and shea butter. It lifts buildup for a fresh-feeling scalp. It's COSMOS Natural and has a pH of 4.0–4.5.
How to use an exfoliating scalp serum
- Start with a dry scalp before wash day.
- Part your hair and apply the serum along the partings.
- Massage lightly and leave it on for the time on the pack.
- Shampoo and condition as usual.
Our Scalp Serum is a weekly lactic acid step with hyaluronic acid and nettle extract. It's fragrance-free and 100% natural origin, for a fresh scalp and fuller-looking roots.
How often should you exfoliate your scalp?
Once a week suits most hair types. If you use lots of dry shampoo or styling product, the scrub can be used as needed. If your scalp is dry or sensitive, try every two weeks. Don't scrub and use an acid serum on the same day.
After you exfoliate
A clean scalp is the best base for the rest of wash day. Follow with our Volume Shampoo with keratin and rosemary oil. On another wash day, try a pre-wash Rosemary Scalp Oil massage: our guide to rosemary oil for hair explains how.
When to see a dermatologist
Thick yellow flakes, an itchy or sore scalp, red patches, or sudden hair shedding can be signs of seborrheic dermatitis, psoriasis or other conditions that need proper treatment. Exfoliation is for buildup, not a cure for these.
Frequently asked questions
Is it better to exfoliate your scalp wet or dry?
It depends on the product. Acid scalp serums are usually applied to a dry scalp before washing. Scrubs are used before shampoo; follow the directions on your pack.
What is the white stuff I scrape off my scalp?
Often it's a mix of dead skin, oil and product buildup. If it's itchy, greasy-yellow or comes back quickly, it may be dandruff, so speak to a pharmacist or dermatologist.
How can I remove thick sebum buildup from my scalp?
A weekly scalp scrub or lactic acid serum before shampoo, plus thorough shampooing at the roots, helps lift buildup. Persistent buildup with itching deserves a dermatologist's look.
Does scalp exfoliation help hair grow?
It isn't a hair growth treatment. It keeps the scalp clean and fresh-feeling and helps roots look fuller and less weighed down.
Can I exfoliate my scalp if I have colored hair?
Generally, yes. Focus on the scalp rather than the lengths, and patch test first.
