We’re calling it now, hair wash day is the most arduous beauty task of all. But damn doesn’t it feel good to step out with seriously stunning styled strands? There’s just something about a good hair day that completely lifts your mood and skyrockets your confidence.
If only that fresh blowout feeling could last a little longer, right? Well, we’re here to spill our secrets on how to make the most out of your wash cycle. Yep, we’re talking about stopping greasy strands right from the get-go. And it’s all down to Dermal Therapy’s latest sebum-slowing scalp care range that works to stop oil in its tracks.
Because ICYMI: just like your face, your scalp is skin too. And it’s got a microbiome balance we’ve been ignoring for far too long. And according to Dr Ryan Cruz, scalp oils are just like our blemish-producing face oils (yikes)! So, let’s get to the bottom of this microbiome-balancing, sebum-slowing range and how it’s going to give you the best blowout of your life.
Day One: Wash day
Hair wash day has arrived. And we just bet that you’re ready to turn that grease slick that was once your stunning mane back into bouncy, lightweight tresses. And what better way to do that than to use a glorious range that leaves your strands smelling like peaches? Because who doesn’t want their strands left with a lingering delish scent?
But we’ve got a secret to getting the most life out of your blowout, and it doesn’t involve hitting up the salon. Yep, all it takes is a diligent wash and style cycle and you’ll be seeing a whole lot less grease.

Dermal Therapy Sebum Control Serum

Dermal Therapy Sebum Control Shampoo

Dermal Therapy Sebum Control Dry Shampoo
We start with shampoo (of course). Picking up the Dermal Therapy Sebum Control Shampoo ($18.99 at Chemist Warehouse) is going to give you the freedom to know that your perfectly styled tresses are going to stay pretty well oil-free. Once you’re out of your ‘everything shower’ (AKA a full body workout), it’s time to apply the Dermal Therapy Sebum Control Serum ($18.99 at Chemist Warehouse). And if you’re committed to kicking excess oil production to the curb, this is going to become a nightly step for the next week, okay?
Your strands might now be squeaky clean, but you’ve still got to style them (a key step in extending the wash cycle). But before you come anywhere near those tresses with heat, you’re going to give them a spritz of Wella Professionals Ultimate Repair Protect Leave-In ($60.45 at Adore Beauty). And because we’re doing everything to protect those strands (right?), we’re also only going to hit them with low heat (185 degrees is ideal people).
While we might not have mastered the whole round brush blowout technique (another step in the beauty workout), we have picked up that our hairdressers like to add a little volume with a spritz of dry shampoo. Our pick, Dermal Therapy Sebum Control Dry Shampoo ($7.99 at Chemist Warehouse), also ensures that any excess oil is kept at bay.
To lock it all in, we finish it off with a spritz of high-hold hairspray and we’re ready to go.
Day Two: Perfect hair day
We’re not sure what kind of sorcery it is, but day two in the hair wash journey is always the best. There’s just something about the way it settles into looking completely ‘90s supermodel-esque that we just can’t get enough of. That’s precisely why we do nothing (aside from apply our super serum, of course) to our scalp on this day. But we do make sure we’re sleeping on a silk pillowcase to make the most of our stunning style.
Day Three: Is it time to wash again?
When you start to ask yourself the big questions, AKA ‘can I get away without washing my hair again?’ we’ve got the perfect answer for you. And no, it doesn’t involve a full wash routine. But it does involve a clever can (more on that in a sec) and a few strategically-placed thermal rollers.
Okay, we promise, it’s a seriously easy reset that doesn’t involve a whole lot of time. But what you’re going to need to do is spritz your strands with a touch of water, and apply your Dermal Therapy Sebum Control Serum ($18.99 at Chemist Warehouse) (which is part of your nightly routine by now, right?) and crack out the hair dryer. Yep, give it a quick volume-boosting blast, pause for a spritz of your Dermal Therapy Sebum Control Dry Shampoo ($7.99 at Chemist Warehouse), massage that in (and take a min to appreciate the white cast-free formula). Next, wrap your tresses around a thermal roller ($19.40 at Adore Beauty) and give them another quick hit of hot, then cold air and voilà, refreshed volume is back baby!
Day Four: Last legs
Getting to day four can spell oil-slick disaster, (or at least it used to). But our hot tip for making the most of tresses before we hit the shower is a seriously sleek updo. Sofia Richie-Grainge, eat your heart out, we’re coming for your slick back bun.
Alright, it’s officially time to hit reset and refresh those strands. We’ve made it through four days of oil-busting styling to get here, and the journey is not quite over, yet. Because today, we start it all over again. Yep, pick up your trusty bottle of Dermal Therapy Sebum Control Shampoo ($18.99 at Chemist Warehouse) and hit the shower, because we’re getting to the root cause (see what we did there?) of sebum overproduction. With its triple-active complex (SeboclearTM, SebocytineTM and SymcontrolTM) the clinically-proven, sebum-stemming range normalises the amount of oil your scalp produces. So, by the end of the first week, you’ll be seeing major scalp-balanced benefits.
Trust us when we say, your strands will have never looked so good in your life! Plus, after seven days of diligent Sebum Control Serum application, you can switch it over to being incorporated into your regular oil-busting wash routine. Greasy tresses? Not here!
And because you’ve just had the four best hair days of your life, you’re going to do it all over again, making sure to keep applying your Dermal Therapy Sebum Control Serum each and every night for the first week (AKA seven days). And we promise, you’ll be seeing fresher hair along the way.
