How to Keep Hair Smooth in Humidity: Your 3-Day Anti-Frizz Routine

Humidity can turn a polished hairstyle into frizz before you even make it out the door. But the right routine can help keep hair looking smoother, shinier and more manageable—even when the forecast says otherwise.

Frizz often happens when the hair cuticle is raised and moisture from humid air enters the hair shaft. Dryness, heat styling and damage can make hair even more prone to becoming puffy or difficult to manage.

The solution? Build your routine around moisture, smoothing and humidity protection. Here’s a simple anti-frizz routine designed to help your style stay sleek from wash day through the days that follow.

Step 1: Start With a Smoothing Wash Routine

Long-lasting smoothness starts in the shower.

Choose a shampoo and conditioner designed to cleanse without leaving hair feeling stripped, while helping strands feel soft and manageable. If frizz is one of your biggest concerns, the Paul Mitchell Super Smooth Shampoo and Conditioner make an ideal foundation for your routine.

Focus shampoo primarily on the scalp, then work conditioner through the mid-lengths and ends. Give the conditioner time to coat the hair before rinsing.

Pro tip: Avoid aggressively rubbing wet hair with a towel. Instead, gently squeeze away excess water with a soft towel or microfiber wrap to help reduce unnecessary friction.

Step 2: Add Humidity Protection Before Styling

Once your hair is towel-dried, it’s time to create a protective layer against humidity.

Shake Paul Mitchell 3-Day No Frizz Spray well and distribute it throughout damp hair. The fragrance-free formula is designed to help moisturize, smooth and protect the hair while delivering long-lasting frizz control and glass-like shine. Paul Mitchell states that testing showed reduced frizz after 72 hours in 80% relative humidity across both air-dried and heat-styled routines.

It’s designed for all hair types, including hair that is especially prone to frizz, and can also be used lightly on dry hair when you want an extra boost of smoothness and shine.

Step 3: Choose Your Finish

One of the easiest ways to customize an anti-frizz routine is to choose a styling method based on the finish you want.

For an Effortless Air-Dried Look

Apply your smoothing products evenly, gently shape your natural texture and allow your hair to air-dry.

Try not to touch your hair too much while it dries. Excess handling can disturb the finished texture and encourage flyaways.

For a Sleek Blowout

Apply 3-Day No Frizz Spray to damp hair, then blow-dry in sections.

Direct the airflow down the hair shaft as you dry. Working methodically with smaller sections can help create a smoother, more polished result.

For Maximum Smoothness

For your sleekest finish, Paul Mitchell recommends blow-drying after applying 3-Day No Frizz Spray and following with a flat iron.

Always select a heat setting appropriate for your hair type and avoid repeatedly running hot tools over the same section.

Step 4: Finish Without Weighing Hair Down

The perfect finishing product depends on your hair type and desired style.

For lightweight polish, use a small amount of smoothing serum through the mid-lengths and ends.

For medium to coarse hair that needs additional shine, a lightweight finishing product such as Gloss Drops can help give the style an extra polished appearance.

The key is to start small. You can always add more product, but using too much at once can make freshly styled hair feel heavy.

How to Keep Hair Smooth on Day Two and Day Three

A smooth-hair routine doesn’t have to start over every morning.

Protect Hair Overnight

A loose braid, soft scrunchie or low-friction pillowcase can help reduce overnight friction and keep your style looking more polished the next morning.

Refresh Only Where Needed

Instead of restyling your entire head, focus on the areas where frizz tends to appear first—usually around the hairline, crown and ends.

3-Day No Frizz Spray can also be applied lightly to dry hair for additional frizz control and shine.

Avoid Over-Brushing

Repeatedly brushing dry hair can disrupt the style and encourage unwanted volume or flyaways. Use your fingers, a wide-tooth comb or an appropriate styling brush only where necessary.

Does Anti-Frizz Hair Care Work for Every Hair Type?

Frizz can affect straight, wavy, curly and coily hair, although the ideal routine will look different for everyone.

Fine hair usually benefits from lighter layers of styling products, while thick or coarse hair may need additional moisture and finishing products.

Paul Mitchell's 3-Day No Frizz Spray is formulated for all hair types, including frizz-prone hair, so you can adjust the rest of the routine based on your individual texture and styling preferences.

Your Smooth-Hair Routine, Simplified

Humidity doesn’t have to decide how your hair looks.

Start with a smoothing wash routine, add targeted humidity protection and choose a styling method that works with your hair type. With the right combination of moisture, technique and anti-frizz protection, it’s easier to keep hair looking smooth, glossy and polished for longer.
