If your hair is damaged, colour-treated, dry or just not behaving, the fastest fix is usually the right professional product, not a whole new routine. The salon brands that work hardest for stressed hair are Olaplex and K18 for bond repair, Pureology and Kérastase for colour and blonde care, and Color Wow and Moroccanoil for frizz and shine. All of them are available to buy in Ireland from Millies, with fast next-day delivery and a team of trained beauty experts on hand if you want help choosing.
This guide breaks it down by the hair problem you are actually trying to solve, so you can skip straight to your concern and find the products salons reach for.
Professional haircare is formulated with more concentrated, higher-quality ingredients than most supermarket ranges, and usually fewer of the harsh detergents that strip and dry the hair over time. That is why a salon shampoo can feel more expensive per bottle but often lasts longer, because you need less of it, and why it tends to deliver visible results on damaged or colour-treated hair. It is the difference between masking a problem and actually treating it.
Best for: bleached hair, heat damage, breakage, split ends, hair that feels straw-like or snaps when wet.
When hair is bleached, coloured or heat-styled, the internal bonds that keep it strong start to break. Bond-repair products rebuild those bonds from the inside, which is why they have become the hero category for damaged hair.
Olaplex No.3 Hair Perfector is the at-home weekly treatment that started the bond-building trend. You apply it to damp hair before you shampoo, leave it on, then wash out. Use it once or twice a week for hair that feels stronger and looks glossier over time.
K18 Leave-In Molecular Repair Hair Mask works differently. It is a leave-in you apply after washing, no conditioner, and it repairs damage at a molecular level in around four minutes. It is brilliant for hair that has been through chemical services, heat or environmental stress.
Redken Acidic Bonding Concentrate is a strengthening shampoo and conditioner range for very damaged hair, designed to reinforce weak bonds with every wash. A good everyday choice if your hair needs constant support rather than a weekly treatment.
A simple plan: a bond treatment once or twice a week, plus a bond-supporting shampoo and conditioner in between.
Best for: highlights, all-over colour, blondes, greys, and anyone whose colour fades or turns brassy too fast.
Colour-treated hair is more porous, so it loses moisture and tone quickly. The right products protect your investment between salon visits.
Pureology is built specifically for coloured hair. It is sulphate-free, vegan and colour-safe across the whole range, so it cleanses without stripping your tone. The Hydrate range suits most colour-treated hair, while Best Blonde and the Color Fanatic leave-in are firm favourites for blondes.
Kérastase Blond Absolu is the go-to for blonde, highlighted and grey hair. It helps neutralise unwanted brassy and yellow tones while deeply hydrating, so blonde stays cool, bright and healthy rather than dull and gold.
Olaplex is colour-safe as well as bond-building, so it does double duty if your colour has also left your hair feeling fragile.
Tip: a purple or toning shampoo once a week/once every two weeks is usually enough to keep blonde cool. Using it every wash can over-tone and leave a lilac cast.
Still deciding between brands? Our guides on which Kérastase shampoo to choose and Redken vs Kérastase can help you pick.
Best for: frizz, flyaways, dullness, and hair that falls apart the second it rains or the air turns humid.
Irish humidity is hard on hair. The trick is to seal moisture in and lock the weather out.
Color Wow Dream Coat is the cult anti-humidity treatment. You spray it on damp hair and blow-dry, and it creates an invisible barrier that keeps hair smooth and glossy even in damp, humid conditions. This is the one to reach for if rain ruins your blow-dry.
Moroccanoil Treatment is the original argan oil that smooths, adds shine and tames frizz on dry or coarse hair. A little goes a long way through mid-lengths and ends.
Living Proof No Frizz is a strong everyday range for ongoing frizz control if you want shampoo, conditioner and styling products that all work together.
Best for: anyone who uses a straightener, curling tong or hot blow-dry, which is most of us.
Heat styling without protection is one of the biggest causes of avoidable damage. A heat protectant is the cheapest insurance you can buy for your hair.
Color Wow Dream Coat doubles as heat protection while it smooths, so it earns its place if you blow-dry. Discover How to Use Colour Wow Dream Coat here.
GHD Bodyguard Heat Protect Spray is a lightweight everyday spray from the styling-tool experts, designed to shield hair up to high styling temperatures without weighing it down.
If you take one habit from this guide, make it this: mist heat protection through your hair before any hot tool, every single time.
Best for: noticeably finer hair, more shedding than usual, or the heavy hair loss many people experience a few months after having a baby.
Some shedding after pregnancy is completely normal and usually settles on its own, but the right products can support the hair you have and help new growth along.
Viviscal supplements are formulated to support normal hair growth from the inside and are a popular first step for thinning or shedding hair.
Kérastase Genesis is a salon range designed to strengthen the hair fibre and reduce hair fall caused by breakage, with a shampoo, serum and treatment that work as a system.
If hair loss is sudden, patchy or severe, it is worth checking in with your GP, as it can occasionally point to something treatable like low iron or a thyroid issue.

Best for: itchy or flaky scalp, product build-up, and anyone in a hard-water area where hair feels coated, dull or harder to manage.
A healthy scalp is the foundation of healthy hair, and hard water leaves mineral deposits that dull colour and weigh hair down.
Olaplex No.4C Bond Maintenance Clarifying Shampoo deep-cleanses to remove build-up, hard-water minerals and product residue, while still supporting your bonds. Use it every week or two rather than daily.
A dedicated scalp range from Kérastase or Redken can soothe itchiness, balance oiliness or hydrate a dry, flaky scalp, depending on your concern.
Best for: colour-treated hair, sensitive scalps, curls, extensions, and anyone whose hair feels stripped after washing.
Sulphates are the detergents that create a big lather, but they can be harsh on colour and dry hair out. Sulphate-free formulas clean more gently.
Pureology was one of the first brands to go fully sulphate-free, and the entire range still is, which is why it is a default recommendation for coloured hair.
Olaplex No.5 Bond Maintenance Conditioner and much of the Olaplex range are sulphate-free and colour-safe, so they pair perfectly with a gentle cleanse.
Most stylists land on the same shortlist, because it works: a bond treatment like Olaplex or K18 for repair, a colour-safe, sulphate-free shampoo and conditioner matched to your hair, a heat protectant for styling, and a smoothing or anti-humidity product like Color Wow Dream Coat or Moroccanoil to finish. Get those four bases covered and your hair will look and feel salon-fresh for longer between appointments.
You do not need ten products. Start with three steps:
Cleanse and condition with a professional shampoo and conditioner suited to your hair, sulphate-free if your hair is coloured or dry.
Treat weekly with a bond builder such as Olaplex No.3 or K18 to repair damage before it builds up.
Protect and finish with heat protection before styling and a smoothing or anti-frizz product to lock in the result.

For most people the best at-home repair is a bond treatment used once or twice a week, such as Olaplex No.3 Hair Perfector or the K18 Leave-In Molecular Repair Hair Mask, paired with a bond-supporting shampoo and conditioner like Redken Acidic Bonding Concentrate.
Look for sulphate-free, colour-safe formulas. Pureology is built specifically for coloured hair, and Kérastase Blond Absolu is ideal for blonde or highlighted hair that needs brass control as well as care.
Color Wow Dream Coat is the standout for humidity, creating a water-resistant barrier that keeps hair smooth when it rains. Moroccanoil and Living Proof No Frizz are also reliable for everyday frizz control.
Pureology is fully sulphate-free across its entire range, and Olaplex No.5 and much of the Olaplex line are sulphate-free and colour-safe too.
Yes. Heat styling without protection is a leading cause of avoidable damage. A spray like GHD Bodyguard, or a smoothing treatment like Color Wow Dream Coat that protects as it works, should go on before any hot tool, every time.
Post-pregnancy shedding is common and usually settles on its own. Viviscal supplements support normal hair growth, and a strengthening range like Kérastase Genesis can help reduce breakage. See your GP if shedding is sudden, patchy or severe.
