Frizz shows up in the morning, before meetings, or right after styling your hair. No, it’s not random. This part of the hair is called the cuticle. Strands catch, swell, and puff when those little “shingles” lift. That shell can be broken by heat, hard water, color, and even the weather. Two things need to be done to fix it: treat the cause and seal the surface. Making small changes to your routine can help a lot. For longer results, get a keratin treatment at the salon. This will smooth the surface, fill in weak spots, and slow down the way humidity gets in. There are six main reasons hair stays frizzy. Here are some quick ways to fix each one, as well as how keratin can help your hair stay calm and shiny without changing its natural pattern.

1.   Your Cuticle Is Rough And Often Lifted

The cuticle is a stack of overlapping scales. When it lies flat, light reflects and hair looks smooth. When it’s lifted, from rough towels, harsh shampoos, very hot water, or tight elastics, hair snags on itself. Porous hair (hair with more tiny gaps) lifts faster and releases moisture quickly, which causes that fuzzy halo. Think of it like a roof in the wind; loose shingles flutter and make noise.

Signs you’ll notice

• Hair feels squeaky but looks dull after washing.
• Ends tangle fast; mid-lengths feel rough when dry.
• Styles lose polish as the day goes on.

Try this today

• Wash with lukewarm water; finish with a short cool rinse.
• Blot with a microfiber towel or soft T-shirt—no rubbing.
• Use a gentle, sulfate-free, pH-balanced shampoo.

How keratin helps

• Fills micro-chips along the cuticle so scales lie flatter.
• Forms a thin, smooth film that reduces friction and puff.
• Heat-seals the surface, so hair looks shinier for longer.

2.   Humidity Swells Strands And Sparks Static Flyaway

Dry hair grabs water from the air. When moisture rushes in unevenly, the shaft swells in patches, the cuticle lifts, and your shape expands. Add static from hats, scarves, or plastic combs, and flyaways stand up like tiny antennas. Curls and waves can lose definition not because they’re “bad,” but because humidity keeps pushing and pulling on the surface.

Signs you’ll notice

• Smooth hair at home, frizzy the minute you step outside.
• Halo around the crown; wisps that won’t lie down.
• Curls that separate instead of clumping together.

Try this today

• Layer a light leave-in or serum before heading out.
• Use a boar-mix brush or wide teeth; avoid hard plastic.
• Sleep on silk or satin to reduce friction overnight.

How keratin helps

• Adds a humidity buffer so water enters more slowly.
• Lowers surface friction, which reduces static and fraying.
• Helps curls keep their coil pattern with fewer flyaways.

3.   Too Much Heat Breaks Bonds And Dries

Blow-dryers and irons work by shifting hydrogen bonds inside the hair while removing water. High heat without protection can crack the cuticle and dry the cortex (the inner core). Once rough, the surface grabs moisture from the air and frizzes faster. The usual culprits are very hot tools, multiple slow passes, and skipping heat protectant.

Signs you’ll notice

• Ends look matte and feel crispy even after serum.
• You need more passes to get hair smooth and straight.
• Styles flop as soon as you step outside.

Try this today

• Always apply heat protectant to damp hair and reapply before using irons.
• Keep the dryer moving with a concentrator pointed downward.
• Use the lowest setting that works; work in small sections.

How keratin helps

• Creates a smoother, heat-resistant surface so you need fewer passes.
• Helps hair dry quicker, lowering total exposure time.
• Reinforces weak spots, so results last between washes.

4.   Hard Water And Build-Up Disrupt Smooth Alignment

Minerals like calcium and magnesium from hard water, chlorine from pools, and product residue can cling to hair. This film roughens the cuticle and blocks even moisture flow. You might wash often and still see dullness or puffiness. Clarifying helps, but daily clarifying can strip too much and trigger more frizz.

Signs you’ll notice

• Hair feels “squeaky” but won’t shine or lie flat.
• Curls refuse to clump; straight hair looks cloudy.
• Products stop working like they used to.

Try this today

• Use a chelating or clarifying shampoo once every week or two.
• Rinse with filtered water if your tap is very mineral-heavy.
• Follow with a light conditioner to calm the cuticle.

How keratin helps

• Smooths the surface so residue has fewer places to grab.
• Applied after proper clarifying for a clean, even seal.
• Keeps hair feeling clean longer when you use gentle shampoos.

5.   Color Services Can Raise Porosity And Frizz

Lightening and some dyes open the cuticle to shift pigment. That lift can leave behind tiny gaps. Porous hair loses moisture fast and pulls humidity in just as quickly. Your shade might be right, but the surface isn’t smooth enough to reflect light, so the color looks dull and frizz shows up sooner.

Signs you’ll notice

• Frizz worsened after highlights, balayage, or frequent toning.
• Ends drink products yet still look puffy.
• Color looks flat unless freshly styled.

Try this today

• Space color appointments and add bond-supporting treatments between.
• Use color-safe, low-sulfate shampoo and cool water rinses.
• Seal mids and ends with a light silicone-friendly serum.

How keratin helps

• Temporarily fills those micro-gaps for a calmer surface.
• Boosts gloss by laying the cuticle flatter over the color.
• Makes styling easier, so you use less heat week to week.

6.   Missing Protection Steps Let Frizz Sneak Back

Frizz isn’t always about what you do; often it’s about what’s missing. Hair likes rhythm: gentle cleansing, steady conditioning, and a sealant to lock things in. Skipping leave-ins, sleeping with wet hair, or blow-drying without a nozzle all lift the cuticle. Even healthy hair benefits from small, steady moves.

Signs you’ll notice

• Good hair days are rare and hard to repeat.
• Mid-day puff, especially around the hairline and crown.
• Tangles form at the nape or where straps rub.

Try this today

• Build a simple order: cleanse → condition → protect → style.
• Blot dry, apply leave-in, then dry with a concentrator nozzle.
• Finish with a pea-sized amount of oil or cream on the mid and ends.

How keratin helps

• Gives you a smoother starting point with less friction.
• Let’s products spread evenly, so a little goes a long way.
• With kind aftercare, results can last for many wash cycles.

Conclusion

If frizz keeps showing up, start with small moves: cooler rinses, softer towels, a leave-in, and heat protection every single time. When you want longer-lasting calm, a keratin treatment can fill weak spots, slow humidity swell, and make daily styling quicker.
