Hair Oils & Serums

What do hair oils and serums do for your hair?

Hair oils and serums hydrate, smooth frizz, repair heat damage, support scalp health and protect your strands during everyday hairstyling. Many formulas also double as lightweight leave-in treatments, keeping your hair moisturised and manageable all day long without any extra steps.

We offer hair oils, treatment serums and scalp serums from some of the world's most trusted professional brands, including Australian favourite BondiBoost alongside Kérastase, L'Oréal, Moroccanoil, Paul Mitchell and Redken. Whether your hair is frizzy, curly, dry, coarse, brittle or fine, you'll find what you need in-store at one of our 125+ locations across Australia or online.

What is the difference between hair oil and hair serum?

Hair oils nourish and condition your hair by coating each strand and sealing in moisture. Serums sit on the surface to smooth the cuticle, tame frizz, add shine and shield your hair from heat and humidity. A simple way to think about it is oil for nourishment and serum for polish.

The good news is you don't have to pick one. Layering the two haircare products works a treat if your locks need both moisture and frizz control. Apply your oil to damp hair first, then follow with a serum before heat styling.

Key ingredients in Hairhouse hair oils and serums

Knowing what's in your hair oil or serum helps you pick the right one for your hair. Different ingredients do different things, and once you know what to look for, finding your perfect match gets a whole lot easier.

Here are some of the hero ingredients you'll find across our hair oils and serums at Hairhouse:

• Wheat germ oil is packed with vitamins and fatty acids that nourish, soften and smooth your hair. It's the star ingredient in L'Oréal Professionnel Absolut Repair Oil, which delivers ten benefits in a single application.
• Coconut oil seals the hair cuticle to lock in moisture, tackle dryness, repair split ends and prevent breakage. BondiBoost Rapid Repair Bond Builder+ Finishing Oil helps keep your hair soft, smooth and frizz-free.
• Grape seed oil is lightweight, so it protects against heat, fights frizz and seals in moisture without ever feeling heavy. Perfect if you want the benefits without any greasiness.
• Moringa oil nourishes and conditions your hair, restoring strength and shine. You'll find it in Olaplex No.7 Bonding Oil, working alongside the brand's bond-building technology to repair damaged hair.
• Hyaluronic acid attracts and holds moisture in your hair to reduce dryness, frizz and improve manageability. KEVIN.MURPHY Night Shift Hydrating Overnight Serum uses it to lock in hydration for up to 12 hours while you sleep.

How to use hair oil based on your hair type

Not every hair oil works the same way on every hair type. A few small tweaks to how you apply yours can make a big difference to your results. Here's how to get the most out of your nourishing hair oil:

• For dry or brittle hair, towel dry after washing, then work a pea-sized amount of repair oil through the mid-lengths and ends. Use a wide-tooth comb to distribute it evenly and detangle before heat styling.
• For an overnight oil treatment, follow the same steps above and wrap your hair in a towel before bed. Rinse with shampoo and conditioner in the morning for noticeably softer, healthier-looking hair.
• For frizzy hair and flyaways, apply a small amount of anti-frizz oil to dry hair using your fingertips for all-day frizz control. Olaplex No.7 Bonding Oil is a great option here, as it minimises frizz and flyaways while repairing hair bonds.
• For fine hair, less is more. A lightweight option like Paul Mitchell Marula Rare Oil Light Dry Mist gives you softness and shine without weighing your strands down.
• If you're blessed with curls, scrunch a little oil into damp strands to define your curls and lock in moisture. Let your hair air dry for a soft, bouncy finish.

How often should you use hair oil?

How often you use hair oil depends on your hair type and what it needs, so it's worth starting small and building up from there. Dry, coarse or damaged hair tends to love more frequent use, while fine hair does better with a lighter touch to avoid buildup.

Pay attention to how your hair responds. If it still feels dry or dull between washes, it's asking for more. A greasy scalp, on the other hand, is a sign to scale back and keep the oil focused on your mid-lengths and ends only.

Can hair oil help with hair growth?

Hair oil isn't a hair growth miracle, but it genuinely helps your hair thrive. Work a nourishing hair treatment oil into your scalp regularly to reduce breakage, maintain hydration and create the right environment for healthy hair growth. Massaging it in with your fingertips feels great and may help boost circulation over time.

If you're dealing with thinning hair or just want to give your scalp some extra love, add a dedicated scalp serum like Kérastase Nutritive Nutri-Supplement Scalp Serum to your routine.
