Scalp Care for Dry Scalps, Oily Roots and Sensitive Scalps: Essences, Serums and Treatments
Scalp serums, essences, scrubs and clay masks are everywhere now. Here is which ones make sense for a dry, oily or sensitive scalp, how to use them, and which ones you can safely skip.
Scalp care used to mean "use shampoo". Now there are scalp serums, essences, tonics, scrubs, clay masks and massage brushes, many borrowing ideas and ingredients from facial skincare.
Some of that makes sense. Your scalp is skin, with more oil glands than almost anywhere else on the body, and it reacts to heat, sweat, harsh products and stress like the rest of your skin does. But you do not need a ten-step scalp routine. Most people need one or two well-chosen extras at most.
This guide sorts scalp care by the three most common complaints: a dry, tight scalp; oily roots; and a sensitive, easily irritated scalp. Dandruff and hair loss have their own specific treatments, so if flakes are your main issue, start with Dandruff, Oily Scalp, or Product Build-Up?.
First, figure out what your scalp is doing
These three often get confused:
Dry scalp: feels tight or itchy, especially after washing or in air-conditioned rooms. Flakes, if any, are small, white and powdery.
Oily scalp: roots look greasy within a day, hair goes flat, and the scalp may smell after sweating.
Sensitive scalp: stings, burns, itches or turns pink after certain products, sometimes with no visible flaking at all.
Dandruff, by contrast, usually shows larger, yellowish or oily flakes with itch. It needs an anti-dandruff active, not just a moisturising serum.
Many people have more than one of these at once, for instance an oily scalp that is also sensitive. In that case, treat the sensitivity first. An irritated scalp does not respond well to anything.
Scalp care for a dry, tight scalp
A dry scalp is surprisingly common in Singapore, even with the humidity. Long hours in air-conditioning, very hot showers and harsh, high-foam shampoos all play a part.
Start with the wash. Switch to a milder shampoo and rinse in warm, not hot, water. Dove Derma Scalp Hydration Balance Shampoo
DoveDove Derma Scalp Hydration Balance Shampoo 350 mlOne 350 ml pump bottle of shampoo from the Dove Derma Scalp Hydration Balance range.S$21.49 is a gentle option aimed at scalps that feel dry and tight.
If your scalp still feels uncomfortable, a leave-on scalp serum can help. Kérastase Nutritive Nutri-Supplement Scalp Serum
KerastaseKerastase Nutritive Nutri-Supplement Scalp Serum Leave-In 90mlA luxurious milky fast absorbing formula with a vitamin blend and niacinamide to moisturize dry scalp for immediate comfort, leaving the scalp healthy and refreshed.S$73.19 is a leave-in designed for dry scalps. Apply a few drops directly to the scalp, section by section, and massage in. Using it on damp or dry hair after washing is typical.
Avoid putting heavy hair oils straight onto the scalp to fix dryness. Oils can feed the yeast linked to dandruff and may leave roots greasy, which can turn one problem into two.
Scalp care for oily roots
Oily roots are the classic Singapore scalp problem. Heat and humidity boost oil and sweat, and a long day in the office or outdoors leaves hair flat.
Your main tool is still shampoo: a clarifying or balancing formula, used as often as you need. Beyond that, a few extras can help:
A scalp-specific shampoo with exfoliating ingredients. Aromatica Rosemary Scalp Scaling Shampoo
AromaticaAromatica Rosemary Scalp Scaling Shampoo 400mlAromatica Rosemary Scalp Scaling Shampoo, 400ml.S$25.41 is designed to help clear build-up around the roots.A weekly clay treatment. Kérastase Spécifique Argile Équilibrante

Do not try to "dry out" an oily scalp with harsh products or by washing several times a day. Over-stripping can leave the scalp irritated, and it will still look oily by evening.
Scalp care for a sensitive scalp
A sensitive scalp needs less, not more. Common triggers include strong fragrance, essential oils, menthol and other cooling agents, hair dye, and frequent product switching.
Choose a calm, simple shampoo. L'Oréal Professionnel Scalp Advanced Niacinamide Shampoo Anti-Inconfort

Essence, serum or tonic: is there a difference?
Not a strict one. The names are mostly marketing:
Scalp essences and tonics tend to be watery, often with a refreshing, alcohol-containing base. They suit oily scalps and dry quickly.
Scalp serums are often slightly thicker and may target dryness, comfort or oil control.
Scalp treatments or masks are usually rinse-off products used weekly.
What matters more is whether the product is leave-on or rinse-off, and whether it matches your scalp's main problem.
Scalp scrubs and brushes: helpful or harmful?
Physical scalp scrubs and silicone scalp brushes can help shift build-up from dry shampoo, styling products and sunscreen. A soft silicone brush such as the Tangle Teezer Wet & Dry Scalp Exfoliator & Massager
Tangle TeezerTangle Teezer Wet & Dry The Scalp Exfoliator & Massager BlackTangle Teezer Wet & Dry is a dual-tooth scalp brush for use on wet or dry hair.S$23.69 can make shampooing more thorough without nails scratching the scalp.
Use them gently and not every day. If your scalp is sensitive, inflamed or has any spots or cuts, skip scrubbing altogether.
A simple weekly scalp routine
For most people, this is enough:
Wash with a shampoo chosen for your scalp type, as often as you need.
Once a week, add one treatment: a clay mask or scalp-scaling shampoo for oily scalps, or nothing extra for sensitive scalps.
If you need it, use one leave-on serum on the scalp after washing.
Keep heavy oils and conditioner away from the roots.
Introduce one new product at a time and give it two to three weeks.
When it is not a skincare problem
See a doctor if your scalp is painful, swollen or has pus-filled bumps; if there are thick, silvery plaques; if itching keeps you awake; if you notice patchy hair loss; or if rashes spread to your face, ears or neck. These can be signs of conditions such as psoriasis, infection or dermatitis that need proper diagnosis.
Bottom line
Treat your scalp like the skin it is. Dry scalps need gentler washing and possibly a light serum. Oily scalps need good cleansing and the occasional clay or scaling treatment. Sensitive scalps need fewer, plainer products. Pick the one extra step that fits your problem, and ignore the rest of the aisle.
