You've Been Choosing the Wrong Shampoo Your Whole Life. Here's How to Fix It.

You Pick Cica, HA for Your Skin Type. Your Scalp Has a Type Too.

Think about how you choose your face moisturiser. You consider your skin type, your concerns, your active ingredients. You know that what works for combination skin is different from what works for a compromised barrier. You would not use the same product for both.

Now think about how you choose your shampoo.

For most people, scalp care has never received the same intentional approach as facial skincare. The shampoo on the shelf, the one everyone uses, the one that was convenient. But the scalp is skin, and it behaves like skin. It produces sebum. It can be dry, oily, sensitised, or prone to specific concerns. And like skin, it responds to ingredients that are actually matched to its needs, and struggles when they are not.

Rootonix was built around this idea. Six shampoos, each formulated for a distinct scalp type and concern. One scalp tonic that works alongside any of them. Here is how to find yours.

The Rootonix Shampoo Lineup by Scalp Type

If your hair is getting thinner and flatter: Golden Biotin Shampoo

Thinning hair is often a scalp aging concern before it is a hair concern. The signs of scalp aging, reduced follicle activity, weakened anchoring of individual strands, and overall volume loss, tend to precede visible hair thinning by months or years. The Golden Biotin Shampoo addresses this at the root.

Biotin supports keratin infrastructure, the protein matrix that gives each strand its strength and structure. Astaxanthin, one of the most potent antioxidants available in cosmetic formulation, protects follicle cells from oxidative stress that accelerates scalp aging. Keratin restores structural integrity to strands that have already thinned. Together, they work on both prevention and repair: strengthening what remains and protecting what is still healthy.

Best for: thin hair, low-volume hair, fine hair that has changed texture over time, hair that breaks easily.

If you've been fighting dandruff for years: Anti-Dandruff Shampoo

Persistent dandruff is rarely just a dryness issue. In most cases, it involves an imbalance between sebum production, keratin buildup, and the scalp's microbiome, the ecosystem of microorganisms that live on the scalp surface. When this balance tips, the conditions that trigger dandruff become self-reinforcing: excess sebum feeds the organisms that cause flaking, flaking creates irritation, irritation triggers more sebum production.

The Anti-Dandruff Shampoo addresses all three factors simultaneously. Piroctone Olamine targets the microbial imbalance directly. Zinc Chloride regulates sebum and reduces the oily environment that feeds the cycle. The formula deeply cleanses keratin buildup without stripping the scalp of the moisture it needs to stay balanced. The result is a shampoo that breaks the dandruff cycle rather than temporarily suppressing the symptoms.

Best for: persistent dandruff, flaking with oiliness, scalp that feels itchy and congested, dandruff that returns quickly after washing.

If you're noticing real hair loss: R+ Micro Bio Shampoo

Hair loss at the scalp level often signals that the follicle environment has become hostile: inflamed, clogged, or nutrient-deprived. The R+ Micro Bio Shampoo takes a vegan micro-biology approach, using Spirulina, a microalgae rich in amino acids and minerals, to nourish follicle cells directly. Dexpanthenol (Provitamin B5) supports scalp tissue repair and strengthens the hair shaft from within. Menthol improves scalp circulation, which is essential for delivering nutrients to follicles and removing the waste products that accumulate in a sluggish scalp environment.

The formula is hypoallergenic and gentle enough for daily use, which matters for hair loss routines where consistency over time drives results. Scalp extracts in the formula work to soothe the inflammation that often accompanies and accelerates hair shedding.

Best for: noticeable hair shedding, thinning at the hairline or parting, scalp that feels tight or inflamed, post-partum hair loss, stress-related shedding.

If your scalp feels tight and dry after washing: Hyaluronic Aloe Shampoo

A scalp that feels tight after washing is a scalp that has lost more moisture than the wash replenished, which usually means the shampoo is either too stripping or the scalp is chronically under-hydrated. In Singapore's climate, this is common: air-conditioning removes ambient moisture from the environment, while heat and humidity outdoors trigger sebum production that can mask underlying dryness until washing reveals it.

The Hyaluronic Aloe Shampoo is a moisture-soothing formula built for dry and sensitive scalps. Hyaluronic acid draws water into the scalp tissue and holds it there. Aloe vera soothes irritation and provides anti-inflammatory support. Together, they wash the scalp without disrupting its moisture balance, leaving it comfortable rather than tight from the first use.

Best for: dry scalp, scalp that feels tight or itchy after washing, flaking from dryness (as opposed to dandruff), sensitive scalp that reacts to most shampoos.

If your scalp is oily by noon: Blue Xylitol Shampoo

An oily scalp by midday is a sebum regulation issue, not a cleanliness one. Washing more frequently without addressing the root cause often makes it worse: stripping the scalp triggers a compensatory sebum surge that accelerates the cycle. The Blue Xylitol Shampoo works by purifying from the scalp downward, removing excess sebum and odour without triggering rebound oiliness.

Xylitol regulates the scalp's moisture-sebum balance, reducing the conditions that lead to overproduction. Menthol provides immediate refreshing relief and supports scalp circulation. White Birch extract has astringent and clarifying properties that keep pores clear without drying the scalp out. The formula is specifically designed to leave the scalp clean without the tightness that causes the rebound oiliness pattern.

Best for: oily scalp, hair that feels greasy by noon, scalp with odour from excess sebum, hair that goes flat quickly after washing.

If your scalp is constantly irritated and reactive: SOS CICA Shampoo

A scalp that reacts to most products, stays itchy, or becomes inflamed easily is a scalp in a chronic sensitised state. This can be triggered by product overload, environmental stress, hormonal changes, or an underlying condition like seborrheic dermatitis or folliculitis. Whatever the cause, the first priority is stopping the inflammatory cycle.

The SOS CICA Shampoo is built around Centella Asiatica (Cica) and a 17-ingredient natural extract complex. Cica is the same ingredient trusted in facial skincare for its ability to calm inflammation, support barrier repair, and accelerate skin recovery. On the scalp, it works the same way: soothing itchiness, reducing redness, and creating the stable environment that an irritated scalp needs to recover. The anti-seborrheic formula addresses dandruff-prone and folliculitis-prone conditions simultaneously.

Best for: itchy scalp, reactive scalp that flares with most shampoos, scalp with persistent inflammation or redness, folliculitis-prone scalp, seborrheic dermatitis.

The Step That Goes After Every Shampoo: Rosemary Biotin Scalp Tonic

Shampoo cleans and treats the scalp during the wash. The scalp tonic works between washes, on a clean scalp, delivering concentrated active ingredients directly where they need to go without being rinsed off.

The ROOTONIX Rosemary Biotin Scalp Tonic is a no-rinse leave-on treatment in a sparkling foam format. Apply it after shampooing, massage into the scalp, and leave it. No rinsing. No weight on the hair. The lightweight water-like foam absorbs quickly and completely, leaving no stickiness or residue.

The active blend: Rosemary extract to support follicle health and stimulate circulation, Biotin for root-level nutrition and strand strength, Caffeine to activate follicle cells and reduce shedding, Salicylic Acid to gently exfoliate and clear buildup between washes, and Dexpanthenol for scalp tissue repair. Menthol delivers instant cooling relief on contact, particularly valuable in Singapore's heat where a hot, overheated scalp is a direct contributor to excess sebum production and hair loss risk.

It works with every shampoo in the Rootonix lineup. The shampoo addresses your specific scalp type. The tonic amplifies the results and maintains the scalp environment between washes.

How to Build Your Rootonix Routine

Step 1: Pick your shampoo by scalp type. Use the guide above. If you have more than one concern, lead with your primary one. Most scalp issues have a dominant pattern that, when addressed correctly, brings the secondary concerns under control too.

Step 2: Add the scalp tonic after every wash. Apply directly to the scalp while slightly damp. Massage with fingertips for 1-2 minutes to stimulate circulation and drive absorption. Leave it on. Style as usual.

Step 3: Be consistent. Scalp care, like skincare, works over time. Most people notice a meaningful difference within 2 to 4 weeks of consistent use. The scalp environment changes gradually, and the results reflect that.

Frequently Asked Questions

How do I know which shampoo is right for my scalp?

Start with your most persistent concern. If your scalp is oily by midday, that is your primary concern regardless of other issues. If dandruff keeps returning despite switching shampoos, that is your scalp type. The guide above matches each shampoo to a specific scalp profile. If you are genuinely between two types, the SOS CICA Shampoo is the most broadly tolerated option for reactive or uncertain scalps.

Can I use the scalp tonic if I have an oily scalp?

Yes. The scalp tonic is lightweight and water-like, and it absorbs without residue. It will not add to oiliness. Apply it to the scalp only, not the hair lengths, and the Blue Xylitol Shampoo and scalp tonic will work together to regulate sebum rather than compound it.

How often should I use the scalp tonic?

Daily use is recommended for best results. Apply after shampooing on wash days, and directly to the scalp on non-wash days for cooling relief and continued active ingredient delivery. It can also be reapplied during the day as needed, particularly in Singapore's heat.

Is Rootonix suitable for colour-treated hair?

The shampoos are formulated for scalp health rather than colour protection specifically. If you have colour-treated hair, the Hyaluronic Aloe Shampoo or SOS CICA Shampoo are the gentlest options and least likely to affect colour longevity.

Where can I buy Rootonix in Singapore?

The full Rootonix lineup is available in Singapore through Dear Glow, an authorized retailer, at dearglow.shop. We offer local delivery and international shipping to Malaysia, Hong Kong, Australia, New Zealand, Canada, and the USA.
