A flaky scalp, an itchy beard, a dusting of 'snow' on your shoulders: I've spent a lot of time researching and trialling routines for it, and I've pulled everything together into The Clean Scalp Guide. This post covers the basics and the products I recommend. The full step-by-step routines are in the guide.
Dry scalp or dandruff? Three quick clues
- What the flakes look like: small, dry, powdery white flakes usually point to dry scalp. Larger, oily or yellowish flakes, or thick scale you can scrape off, usually point to dandruff or seborrhoeic dermatitis.
- How the scalp feels: tight and dry, or itchy and greasy.
- Where else it shows up: dandruff often affects the beard, eyebrows and the skin behind the ears too.
These are clues, not a diagnosis, and you can have both at once. If it isn't improving, speak to a pharmacist or your GP.
Three things most people get wrong
- Treating every flake the same. Dry scalp and dandruff need different things, and what helps one can make the other worse.
- Getting the wash frequency wrong. Washing too rarely can make dandruff worse, while washing too often can dry out a dry scalp.
- Assuming heavy 'natural' oils are always nourishing. On dandruff-prone skin, some plant oils may feed the yeast involved. The evidence is mostly lab-based, so it pays to be careful.
What's inside The Clean Scalp Guide
- A simple flake test to work out which problem you have
- Six complete, self-contained routines: dandruff for men (short hair with beard, and longer hair with beard) and women (uncovered hair, and hijab or head covering), plus dry scalp routines for short hair and for medium to long hair
- A plan for the days you have to wet your hair but don't want to shampoo (ghusl, gym, swimming) when plain water leaves you itchy and flaky
- How to add oils, curl creams and beard oils back safely
- A 4-week tracker and a quick reference card
I've checked the guide against UK product information and published guidance, but it is general information, not medical advice.
The products I recommend
Here are the products the guide uses, with what to look out for. Always read the label before you buy, as formulas and fragrance can change.
For dandruff
Nizoral Anti-Dandruff Treatment Shampoo (ketoconazole 2%)
A medicated shampoo for stubborn dandruff and seborrhoeic dermatitis. For adults and over-12s. Always follow the directions on the pack and in the leaflet.
Head and Shoulders Suprême Moisture
A gentle everyday anti-dandruff shampoo with piroctone olamine, which the brand says is suitable for daily use. The Suprême range also contains argan oil and dimethicone as conditioning agents, which rinse off.
HEETA silicone scalp brush
A soft silicone brush for working shampoo into the scalp with gentle pressure. Fingertips work just as well if your scalp is sore, and you should never use your nails.
For dry scalp
Aveeno Skin Relief Soothing Shampoo
A soap-free oat shampoo made for dry, sensitive scalps. It is not a medicated shampoo. The listing describes a light fragrance, so check the pack if you want a fragrance-free option.
The Ordinary Natural Moisturizing Factors + HA Scalp Serum
A lightweight, leave-in hydrating scalp serum with hyaluronic acid and squalane, useful for that tight, dry-scalp feeling. Check the pack for fragrance and patch test first.
Everyday essentials
The Ordinary 100% Plant-Derived Squalane
A single-ingredient, plant-derived squalane. Unlike many plant oils, it has no fatty acids for the dandruff-related yeast to feed on, which makes it a sensible everyday oil for tight skin and softening beard hair. It is a moisturiser, not a treatment, and there are no clinical trials proving it helps dandruff, so patch test it first.
Biossance 100% Squalane Oil
Another plant-derived squalane in a larger bottle. Check that the ingredient list shows squalane only.
For the beard
Cetaphil Gentle Skin Cleanser
A fragrance-free, soap-free cleanser that works well for the beard and the skin underneath it. Rinse it off thoroughly.
Optional extras once things have calmed down
These are not for when your scalp or beard is actively flaking. Add them back slowly, one at a time, once things have been calm for a few weeks.
Moroccanoil Curl Defining Cream
A styling cream for wavy and curly hair. It contains argan oil and fragrance, so introduce it slowly and keep it on the hair, away from the scalp.
Viking Beard Wash
A scented (sandalwood), oil-infused beard wash with argan and jojoba oils. It is not suited to the clearing phase, so consider it only once your beard skin has been calm for a while, and test it slowly.
Want the full routines?
Knowing which products to buy is only half of it. The Clean Scalp Guide shows you exactly how to use them, step by step, for your hair length and type.
This post is general information and not medical advice. If your symptoms are severe, not improving after about a month, or come with a red, sore or swollen scalp, pain, oozing or patchy hair loss, please see your pharmacist or GP. Always read and follow the label of any product you use. Results vary from person to person. Product names are trademarks of their owners and are mentioned only as examples.
