We scrub our bodies smooth with sugar and salt, take rotating brushes to our faces and buff our feet to silky softness… but what about the skin on top of our head?
Yes, the scalp is skin. And while you give it a seeing-to every time you shampoo, it needs extra love if you want hair that’s smooth, strong, glossy and flake-free.
Skipping scalp care, on the other hand, may leave you with weak, stressed or clogged hair follicles (cue: lack of glossiness, flakes, thinning strands and excessive hair loss).
So… let’s take a deep dive into scalp health (which equals hair health), shall we? From why we need scalp exfoliation to the best scalp scrubs it’s ALL here.
Why do you need a scalp scrub?
Shampooing, conditioning, masking and glossing the external hair strands can only do so much, since they have already reached peak growth.
What’s important is to cleanse and nourish them at the very source — the hair follicles, which are rooted in the scalp.
And like all other skin on our body, the scalp also needs help.
It needs oxygen, moisture and nutrients.
And since our hair is rooted in the scalp, it is kind of important! So… scalp care is a necessity rather than an indulgence.
What does a scalp scrub do for our hair?
Specially formulated scrubs are the best form of scalp care, which pays off rich dividends by making our hair shinier, smoother and stronger. How? Let me count the ways.
Scalp exfoliation tackles excess oil
You know how the sebaceous glands (oil glands) on our face keep skin moisturised and protected but sometimes go into overdrive, leading to an oil slick and clogged pores?
The same thing happens with our scalp.
Enter scalp exfoliation to gently lift away these excess oils, unclogging har follicles and bringing the skin back into balance.
And also balances out a dry scalp
A scalp that’s too dry and tight, on the other hand, will slow down hair growth and cause excessive breakage.
A good scalp scrub re-balances the natural oil distribution, thereby creating a nourishing environment for hair growth. And it sorts out an itchy scalp!
Removes product build-up
Like with the rest of our body, scalp exfoliation helps remove product residue build-up from hair spray, gels, dry shampoo and the gazillion other things that can clog follicles and stop hair from growing properly.
Keeps yeast in check
A scrub also goes a long way in controlling the scalp’s Malassezia levels. Malassezia is a type of yeast that damages hair follicles (leading to hair loss), while also causing dandruff.
Busts dead cells and boosts cellular turnover
Scalp scrubs remove follicle-clogging dead cells, thereby saying buh-bye to scalp acne (gross but it exists!). This also helps make way for fresh, healthy new cells to surface, which then become the bedrock for long, thick, healthy hair.
Combats free radical damage
Our scalp is as susceptible to environmental damage (sun, cigarette smoke, pollution, airborne chemicals!) as the rest of our skin. And this environmental damage triggers the formation of free radicals, which affects the proteins responsible for hair growth.
An effective way of neutralising them to prevent hair loss? Scalp exfoliation, which draws out the molecules before they can do damage.
Plus, the extra stimulation helps boost blood circulation to the hair follicles, which ensures an optimal supply of nutrients to nourish the scalp and ensure healthy hair growth.
What is a scalp scrub?
They’re exactly what they sound like: Scrubs or exfoliators for your scalp.
And given the accelerated growth in hair technology nowadays — you have almost as many options for your strands as you have for your skin! —there is a choice between chemical and physical formulations for your scalp care ritual.
Physical scalp scrubs
A physical exfoliant, these contain ingredients to manually scrub the scalp. Think: Salt, sugar, charcoal, clay, nuts and fruit pits.
They are particularly efficient in controlling excess oils, handling dandruff and promoting circulation.
When going with a physical exfoliator, look for one with smaller grains and massage it in gently to avoid the risk of causing micro-tears in the skin.
Chemical scalp exfoliators
Chemical exfoliants, on the other hand, contain active ingredients like alpha-hydroxy-acids (AHAs) and beta-hydroxy-acids (BHAs) to chemically lift away dead cells and other buildup. Think: Glycolic acid, lactic acid and salicylic acid. For the skin… on our scalp.
You leave them on for a while (usually 5-10 minutes, depending on the formula) and then shampoo them away — no massage required.
They work brilliantly for unclogging the pores, busting dead cells and boosting cellular turnover.
How often do you need scalp exfoliation?
The general rule of thumb is every 7-10 shampoo cycles for the best scalp care regimen — which usually equates to twice a month for most people.
If you use a lot of hair styling products or have oily roots, aim for the lower end of the scale.
Over-exfoliation, as with any other area of the body, is as bad as not exfoliating at all. It can over-sensitise the scalp, cause it to produce excessive oils or dry it out to the point of tightness and undernourishment.
In short: Scalp scrubs, like most things in life, work best in moderation!
