Sunscreens, targeted toners, pricey serums, and coddling creams – we do so much for our skin. But what about our scalp? Often, it merely gets nothing more than a quick lather, rinse, and repeat. Granted, it’s easy to overlook what we can’t see. Many of us focus on the ends, frizz, and smoothness of our hair, believing this will give us the longer, shinier locks we desire. However, neglecting our scalp undermines all the effort we put into our hair care.
The truth is, the scalp is an extension of the skin on our face—just as vulnerable, if not more so, to ageing, sun damage, irritation, itchiness, and dryness. Simply put, the scalp is the bedrock – or root (see what we did there?) of happy healthy hair and hair growth.
It’s time to turn our attention to our follicles. The same meticulous care we give to our skin can make a significant difference in the health of our hair. Conversely, neglecting our scalp can lead to damaging conditions that demand our attention.
So read on to explore the often-overlooked realm underneath our tresses and discover why nurturing our scalp is essential for creating a healthier environment in which hair can truly flourish.
Understanding more about the scalp
Your scalp might resemble the rest of your skin, but it has its own unique characteristics. Unlike the typical three layers of skin, the scalp has five, giving it a bit more density. It’s home to about 100,000 hair follicles, and also boasts more sebaceous glands—those oil-producing powerhouses—than any other part of your body.
The sebaceous glands produce sebum, a natural oil that conditions your hair and skin. The amount of oil produced on the scalp varies from person to person, those with a dry scalp produce less sebum, while those with an oily scalp produce more.
Because of all these sebaceous glands, your scalp has a lower barrier function, which means it struggles more to replenish and hold on to moisture compared to the rest of your skin. And let’s not forget, your scalp is often the most exposed to the sun, making it even more delicate.
Why scalp care matters
Our scalp is home to hundreds of thousands of hair follicles, each responsible for growing an individual strand of hair. The health of your scalp directly influences the health of your hair, as every follicle is deeply rooted in the scalp. Hair growth begins below the surface, so by the time a strand emerges, it has already been formed. This means that everything involved in hair creation and growth relies on the condition of your scalp and its underlying structures.
If your scalp isn’t given the right care, hair growth can slow down, and the hair that does emerge might be more delicate and susceptible to breakage. The natural bacteria and microorganisms living on your scalp also populate the hair follicles, playing a crucial role in the overall health and quality of the hair that grows.
To maintain an optimal environment for hair growth, it’s essential that your scalp and its follicles remain clean, clear, and free from buildup—whether it’s sebum, dead skin, dandruff, or excess products. The scalp and its follicles have their own unique microbiome, and when that balance is disrupted, it can lead to issues like dermatitis, eczema, dandruff, and more. These problems aren’t just skin-deep; they often contribute to thinning hair, breakage, dullness, and rough texture. Even worse, poor scalp health can lead to premature hair loss, which might become permanent if left untreated.
We unknowingly subject our scalps to all sorts of damage. From increased sun exposure and environmental pollution to product buildup and simple neglect, our scalps endure a lot. That’s why scalp care is essential—it forms the foundation for healthy hair growth. A well-cared-for scalp is crucial for promoting strong, thick, and beautiful hair.
In short, here’s why keeping your scalp clean and nourished is so important:
- A healthy scalp supports healthier hair follicles and stronger hair shafts.
- A clean scalp creates an optimal environment for hair growth.
- Regular cleansing prevents problems from escalating—like itchiness, inflammation, and clogged follicles from product and dirt buildup.
- A clean scalp helps avoid unpleasant odours and dandruff.
- Nourishing your scalp ensures that your hair shaft receives the nutrients it needs, leading to fuller, thicker-looking hair.
- Caring for your scalp can slow the effects of hair ageing. Just as ageing skin loses moisture and develops wrinkles, older hair follicles may not produce hair as luxuriously as they once did. Anti-aging efforts focused on retaining nutrients and moisture are key to growing as many healthy hair follicles as possible.

Causes of an unhealthy scalp
Recognising the signs of an unhealthy scalp is the first step to healthy hair growth. Many factors we encounter daily—such as poor eating habits, exposure to toxins, extreme weather, and stress—can significantly impact scalp health. However, one of the biggest culprits is product buildup on the hair and scalp, especially when combined with irritating ingredients like alcohols, parabens, and sulphates that strip away essential moisture.
Another important aspect is washing your hair the right amount for your scalp type. Over-washing can cause dryness, irritation, and flakiness, while infrequent washing allows product, dirt, and oil to accumulate, leading to clogged hair follicles, inflammation, and potentially poor hair growth. Striking the right balance for your scalp type is essential.

How should you care for your scalp?
At the heart of it, proper scalp care begins with removing debris and product build-up with shampoo. A helpful tip is to brush your hair before you hop in the shower—this loosens debris, making it easier to rinse away.
Just as you select a specific regimen for your face, your scalp care routine should be tailored to meet your scalp’s current needs, taking into account your hair type, texture, general health, and lifestyle. For instance, if your scalp tends to be dry, avoid over-stripping it with harsh scrubs.
Regular scalp treatments are also essential. Many of our scalp treatments deeply cleanse your scalp of dead skin buildup, reoxygenate the hair follicles, and stimulate blood circulation, ensuring your scalp stays in top condition and maintaining optimal hair and scalp health.
When you give your scalp the care and attention it deserves, you’ll be rewarded with hair that shines with vitality and strength.
