Effortless, cool-girl waves are the beauty equivalent of the white T-shirt: unfussy, timeless and endlessly adaptable. Inspired by the routine spotlighted by SheerLuxe’s fashion and creative director, Lu, this guide distils the universal techniques—rather than specific product names—that keep her hair looking polished yet undone. From wash-day foundations and heat settings to setting, brushing out and day-two refresh strategies, here’s how to get that lived-in texture with shine, movement and minimal damage.
Build the Base: Wash, Prep & Protect
Great waves start before you switch on a tool. The way you cleanse, condition and prime can make or break how your hair holds shape and resists frizz throughout the week. Think of this stage as the scaffolding that supports your style.
- Cleanse smartly: Use a gentle, sulphate-free shampoo for regular washes to preserve colour and moisture; clarify once a week (or every 2–3 washes if you use heavy stylers) to remove product, mineral and pollution build-up.
- Mind your water: If you live in a hard-water area, a monthly chelating treatment helps prevent that dull, weighed-down feel that stops waves springing back.
- Condition with intent: Apply conditioner mid-length to ends, detangling with a wide-tooth comb. Fine hair benefits from a lighter formula; coarse or porous hair often needs richer hydration or a mask once weekly.
- Prime for performance: On towel-dried hair (microfibre towels reduce friction and frizz), apply a lightweight leave-in for slip, followed by a heat protectant rated to 185–200°C if you use hot tools.
- Set the stage: For hold that still feels touchable, work a mousse or light styling foam through lengths. If flat roots are your nemesis, mist a root-lifting spray through the crown.
Dry with purpose: Rough-dry to 70–80% using a nozzle and medium heat, directing airflow down the hair shaft to smooth the cuticle. This prevents over-reliance on hot tools later and gives your waves a smoother, shinier finish. If your hair has a natural bend, clip the front sections into a slight curve while it cools to encourage face-framing shape.
Make the Wave: Tools, Temperature & Technique
Cool-girl waves are less about perfect curls and more about attitude: relaxed, slightly irregular, and polished only where it counts. The right tool, settings and sequence matter as much as the products.
Pick your barrel wisely: mid-length hair often thrives with a 28–32mm tong for loose movement; short to bob-length hair suits 24–28mm; long hair can handle 32–38mm. A tong with a clamp gives a smooth, glossy S-wave; a wand yields a more undone, beachy texture. For ultra-low faff, use straighteners to create S-bends—particularly effective on hair that doesn’t hold a curl easily.
- Temperature sweet spot: Fine or sensitised hair: 150–170°C. Medium hair: 170–185°C. Coarse or resistant hair: up to 200°C, but only when needed. Always use heat protection.
- Section with intent: Create ear-to-ear and temple sections. Work in horizontal layers 2–3cm thick. The thinner the section, the longer the wave will last.
- Direction matters: Curl the front pieces away from the face. Alternate directions through the back for movement that doesn’t clump together.
- Leave the ends out: Stop 2–3cm before the tips for that relaxed, modern finish. A quick, straight pass on the ends with a warm plate can refine the look.
- Cool to set: Catch each fresh curl and hold it loosely in your palm for five seconds, or clip for extra longevity. Letting hair cool in shape ‘sets’ the wave.
Brush out with intention: Once cool, use a mixed bristle brush to blend the sections into an easy wave. If your brush creates too much slip, switch to a wide-tooth comb and then your fingers. Finish with a texturising spray for grip, a flexible hairspray for light hold and a pea-sized drop of shine serum through the ends. Mist a humidity shield if your hair expands in damp weather.
Alternative paths: Naturally wavy? Apply a curl cream and diffuse on low heat, scrunching gently; you may only need to tong the face-framing pieces and the crown. Straight hair that drops fast can benefit from pin-curling the front sections for 10–15 minutes after tonging to lock in shape.
Make It Last: Day-Two to Day-Four Refresh
Lu’s easy-going finish hinges on longevity—soft movement that survives a commute, weather and sleep. The secret is less about heavy re-styling and more about quick, strategic refreshes.
- Night-time insurance: A silk or satin pillowcase reduces friction and keeps the outer cuticle smoother. Tie hair in a very loose, high ‘pineapple’ with a silk scrunchie, or twist into two soft buns to preserve bends.
- Morning reset: Lightly mist lengths with water or a reactivating spray and press (don’t scrunch aggressively) to revive curves. Re-touch the front two sections with your tool if needed; it’s the quickest way to look polished.
- Scalp care between washes: Use a translucent dry shampoo at the roots before bed rather than in the morning to allow it to absorb overnight without dulling shine.
- Rebuild volume: Flip hair upside down and blast with a cool shot from your dryer for 10–15 seconds. Mist a little texturising spray into the mid-lengths only.
- Don’t overload: Stacking products daily leads to dullness and droop. Keep refresh days light—air, a hint of reactivator, minimal top-ups of texture.
On days three or four, a half-up bend, low ribboned pony, or a soft claw-clip twist will elegantly hide any flattening without erasing texture. A tiny amount of pomade on fingertips will tame flyaways around the parting and edges.
Healthy Hair, Better Waves: Maintenance That Pays Off
The most effortless hair often belongs to those who look after the fibre between styling sessions. You don’t need an elaborate shelf of products; you need smart habits that keep strength, moisture and shine in balance.
- Protein–moisture balance: If hair feels mushy, stretchy or won’t hold a curl, it may be over-moisturised—add a light protein treatment. If it’s brittle and straw-like, prioritise hydrating masks and leave-ins.
- Bond-building when needed: Colour or heat usage can weaken internal bonds; a weekly bond-repairing treatment can improve elasticity so waves last and brush out smoothly.
- Regular trims: Dust ends every 8–10 weeks. Frayed tips refuse to lie neatly, which ruins that glossy ‘swoosh’ through the lengths.
- UV and pollution defence: UV filters and antioxidant mists help preserve tone in colour-treated hair and keep the cuticle smoother in the city, preventing roughness that shows as frizz.
- Scalp-first approach: Once or twice a week, massage your scalp for a minute pre-shampoo to boost circulation. Healthy growth and balanced sebum keep roots bouncy rather than greasy.
Lastly, respect your heat habits. If you style most days, bring the temperature down a notch, shorten contact time and protect religiously. If you style once or twice a week, prioritise that 70–80% blow-dry prep—when the hair is already smooth and mostly dry, your tong or straighteners only need to kiss each section to create shape.

Key Takeaways
- Strong foundations make styling easy: cleanse build-up, condition smartly and prime with heat protection for waves that look smooth and last longer.
- Technique beats tool: alternate curl directions, leave the ends out and set each section to cool for that undone yet polished finish.
- Choose temperature intentionally: 150–185°C suits most hair; coarse or resistant types can go higher briefly, always with protection.
- Refresh lightly: preserve texture overnight, re-touch face-framing pieces and avoid daily product stacking to keep movement bouncy, not crunchy.
- Healthy fibres hold better: maintain protein–moisture balance, trim regularly and protect from UV and pollution for glossier, longer-lasting waves.
Frequently Asked Questions
What barrel size is best for ‘effortless’ waves?
For most mid-length styles, 28–32mm creates loose movement. Shorter hair usually prefers 24–28mm; very long hair can handle 32–38mm for a relaxed bend.
What temperature should I use to avoid damage?
Start at 160–170°C and adjust by hair type. Fine/sensitised hair: 150–170°C. Medium: 170–185°C. Coarse/resistant: up to 200°C only when needed—and always use heat protection.
How do I stop frizz while keeping the style soft?
Direct the dryer downward during prep, use a heat protectant, let curls cool before brushing out and finish with a humidity shield. A touch of serum only through the ends keeps softness without grease.
My waves drop quickly—what can I change?
Take smaller sections, hold the tool a second or two longer, clip to cool for 10–15 minutes and switch to a flexible hold spray. Clarify regularly; build-up can weigh hair down.
Can straighteners create the same wave?
Yes. Use the S-bend technique: clamp briefly, push the hair into an ‘S’ shape as you move down the strand, alternating direction. It yields a loose, fashionable bend with minimal effort.
Salt spray vs texturising spray—what’s the difference?
Salt sprays give a drier, beachy grip and can roughen fine hair if overused. Texturising sprays tend to be lighter and more brushable, adding airy volume without crunch.
How often should I clarify?
Once weekly is a good starting point if you use stylers regularly or live in a hard-water area. Reduce frequency if hair feels dry; increase if it looks coated and lifeless.
What’s the quickest way to look polished on busy mornings?
Mist lengths lightly with water, re-bend only the front two sections away from the face, brush out, then add a whisper of texturising spray through the mid-lengths.
