Humidity can transform a sleek style into a frizzy mess in minutes. Whether it’s a hot summer day or a rainy Irish afternoon, moisture in the air causes hair to swell, puff, and misbehave. The good news? You don’t have to surrender to the frizz. With the right salon treatments and expert care, your hair can stay smooth and sleek no matter the weather.
Here, the experts at Peter Mark share their top humidity-fighting treatments, along with pro tips and products to help you enjoy better hair days, even when the forecast says otherwise.
Why Humidity Causes Frizz
Hair is like a sponge. When the air is humid, hair absorbs excess moisture, causing the strands to swell and disrupt their natural shape. This is especially true for wavy, curly, or dry hair types, which are more porous and prone to frizz.
Frizz happens when the outer layer of your hair (the cuticle) lifts and allows moisture to penetrate, creating uneven texture and fly-aways. Another key cause of a frizzy foible is broken bonds.
'What are bonds?' we hear you say. Simply put, bonds are the chemical links which hold the proteins of our hair together, primarily keratin, also known as keratin chains. These chemical links when broken can result in loss of hair strand strength, damage and the dreaded frizz.
The key to controlling frizz is keeping hair smooth, sealed, and hydrated.
Salon Treatments That Fight Frizz
Reparative Treatment
Reparative treatments like Kérastase Premiére, while the main aim is to neutralize and prevent further calcium build-up, it also works to seal the cuticle, reducing frizz for weeks. The result is hair that's soft, manageable, and easier to style—even in high humidity.
K18 Molecular Repair, unlike traditional treatments, works at the molecular level to reconnect broken keratin chains, restoring hair's strength, softness, and elasticity.
Olaplex Bond Building Treatments
Unsurprisingly, frizz often starts with damaged hair. Olaplex works on re-linking broken bonds, strengthening hair and reducing frizz from the inside out. It's also a colour-safe treatment.
Moisture Infusion or Deep Conditioning
Hydrated hair is less likely to frizz. Moisture-rich Kérastase Fusio Dose treatments can be tailored to nourish you hair deeply, keeping it smooth and healthy in humid conditions.
Pro Styling Tips for Humid Days
Layer Anti-Humidity Products
Start with a smoothing serum or leave-in conditioner, then apply a humidity-blocking spray. Products like Color Wow Dream Coat or Redken Frizz Dismiss are great choices.
Use Heat Tools Strategically
Blow-drying with a nozzle pointing down towards your brush and finishing each section with cool air helps to seal the cuticle. The max heat on a hairdryer isn’t always necessary, A good hairdryer will do most of the work for you on a medium heat. Regardless of the hairdryer you use, always use a heat protector before you blow-dry to guard against moisture and heat damage.
The ETI Stile Digital Plus is a Peter Mark stylist favourite for a lightweight, fast-drying, long-life hairdryer.
Choose the Right Hairstyles
Protective styles like sleek ponytails, braids, or buns can help reduce exposure to humidity while keeping your hair chic and under control.
