Somewhere around September, the same sentence starts arriving in the studio: I just have frizzy hair.
Sometimes that’s true. Often it’s only part of the story. Frizz can come from your hair’s natural make-up, but it can also be a signal that something is out of balance, and in spring that something is usually the weather, a routine that hasn’t caught up, or both. Knowing which one you’re dealing with changes how you care for it.
Can frizz be your hair type?
Yes. Hair that is naturally dry or coarser is more prone to frizz. It isn’t damaged or doing anything wrong; it simply needs more hydration than finer or naturally smoother hair. For these hair types, the aim isn’t to eliminate frizz entirely. It’s to keep the hair well hydrated so it holds its shape and stays soft rather than rough.
What else causes frizzy hair?
When frizz isn’t simply the hair type, we usually find one or more of the following: dryness, damage from lightening or heat, a cut that isn’t working with the hair’s natural texture, or curl that has never been taught how to behave.
There’s also one cause that’s often overlooked: new growth. Fresh hairs coming through create shorter lengths within the hair that don’t yet have the weight to sit down. On their own they hover above the rest and read as frizz, when in fact they’re simply young hair that hasn’t caught up.
What happens inside the body matters too. Poor nutrient absorption can affect the hair and how it frizzes, and so can certain medications. If your hair has changed in texture or behaviour and there’s no obvious external reason, it’s worth considering what else has changed in your health or routine.
Why is my hair frizzier in spring?
Humidity is the main reason. As the air warms and fills with moisture, hair that is dry or porous draws that moisture in, swells, and loses its smooth line. Naturally dry and coarse hair feels this first.
But the season brings other changes too. Many people exercise more as summer approaches, which usually means more sweat and more frequent washing. Many reach for more heat styling to fight the humidity. And spring is when people start going lighter. Each of these, on its own, can tip hair further out of balance.
What makes frizz worse?
The habits that feel like solutions are often the ones that feed it.
Excessive heat is the most common. Hot tools can flatten frizz for the morning, but repeated heat without protection dries the hair out, and dry hair is more likely to frizz the next time the air turns humid.
Going lighter too quickly is another. Lightening done gradually over many visits is far kinder to the hair than a dramatic lift in a single appointment.
And then there’s the familiar cycle: going to bed with wet hair, then trying to iron it back into control in the morning. The hair dries in whatever shape the pillow gives it, and the morning becomes a repair job carried out with heat.
How do I stop my hair frizzing in humid weather?
Start with protection. If you’re using heat, a heat protectant is not optional. We recommend EVO Day of Grace or EVO Icon Welder. To seal and smooth, Teknia Full Defense Serum helps hair hold its line against humidity. For wavy or curly hair, Clever Curl Hydramist adds moisture so the curl forms properly rather than puffing out.
If your hair is naturally dry or coarse, make hydration a constant rather than something you reach for once frizz appears.
Then keep your cuts regular. Tired ends split and fray, and frayed ends look like frizz no matter what you apply to them. Consistent trims keep the ends clean and the shape intentional, a theme we return to often: hair that looks effortless comes from steady care, not last-minute rescue.
When is frizz a sign of something more?
Usually, frizz is the weather or the hair’s natural texture. Occasionally, it’s worth a closer look.
If the ends look more flyaway than frizzy, it can signal shedding or unexpected hair loss. And if you’ve had a significantly lighter blonding service and notice a frizzy, shorter layer sitting through the hair, it may be breakage rather than frizz.
The best protection is prevention. Make sure your colourist is using a bond builder during lightening services, and keep up with a bond-building treatment at home between appointments.
If you’re unsure which you’re seeing, that’s exactly what a consultation is for.
Frizz is information
Whether it comes from your hair’s natural texture, the season, your routine, or something happening inside the body, frizz is telling you something. Understand what it’s responding to, give it what it needs, and it becomes far easier to manage.
