Anyone with frizzy hair knows the struggle of painstakingly flat ironing your locks only to step outside and have them turn into a frizzy mess.

It’s like all your hard work goes down the drain in an instant!

In my opinion, the reason most people can’t keep their hair looking silky smooth and straight all day long is that they underestimate the importance of investing in good heat styling tools and anti-frizz products.

Nail down these two, and you’ll be able to transform your hair from frizz to fabulous in no time – at a click of a button.

So let me show you how to keep frizzy hair straight with the products I use and totally swear by.

Step 1: Gather the Proper Tools & Products

The most important part of making your hair smooth and straight is to use the right products and equipment.

Everyone’s hair is different. Some are thin, some are fine, some have low porosity, and some have high. That’s why you need to get hair products that suit your hair type. If you’re not doing it already, be very selective about your hair products. Don’t just buy any drugstore shampoo or conditioner. Look for products that are compatible with your hair type.

The same goes for flat irons, blow dryers, and other hot tools.

Let’s start with your shampoo. There are a lot of different shampoos that you can choose from. The best shampoo that works for frizzy hair is one that is sulfate-free and moisturizing. I highly recommend the Redken Frizz Dismiss in this category. It’s a bit pricey, but it makes a huge difference right from the first use.

Never skip the conditioner.

The purpose of a conditioner is to rebalance the pH level of the hair after shampooing and help the cuticles to close. A conditioner is the first line of defense against frizz, so ensure you get a good one. The Redken Frizz Dismiss conditioner is our top pick to complement its excellent anti-frizz shampoo.

To maintain an effective frizz-free hair care routine, coconut and argan oil products are also highly recommended to boost moisture and keep the hair soft and healthy from the inside out.

Getting The Right Styling Tools

Everything from your flat iron, blow dryer, hot brush, or detangling brush can make a difference in reducing frizz.

So look for heat styling tools that offer smart heat control technology to minimize frizz and hair damage.

Step 2: Ace Your Washing Routine

To begin your hair straightening process, first, wash your hair.

Avoid using hot water a heat opens the cuticles. Use lukewarm water to wash and finish off with a cold rinse. This helps close the hair cuticles.

Make sure you use enough conditioner to smoothen the hair and help the cuticles to rest, which is vital to counter frizziness.

Step 3: Gently Towel Dry Your Hair

Use the microfiber towel and gently press and squeeze your hair dry. Having dry hair is very important for the upcoming steps, but that doesn’t mean you need to rub with all your strength. Just dry out the wet hair as best as you can.

Step 4: Apply a Straightening Spray or Cream

This step can be skipped, but for the best output, I highly recommend it. Once you’re done towel drying, apply styling products like a heat protectant spray, anti-frizz cream, or leave-in-conditioner to seal in moisture. Mainly focus on the ends but apply it throughout your hair.

Use a generous amount but don’t over saturate your hair. Otherwise, it will feel lumpy when dry.

Step 5: Blow Dry Your Hair

Next, it’s time for you to use your blow dryer. But before that, use your comb and separate your hair into two parts. This will make blow-drying easier.

To blow-dry, point your dryer downwards all the time. This will ensure that your cuticles lie flat. You should also use a bristle brush during the air-drying process.

Swap between the hot and cold settings of your blow-dry from time to time. This will allow you to manage the overall heat your hair is exposed to.

Step 6: Separate Your Hair into Sections

Once the blow-drying session ends, it’s time for you to straighten your hair with a straightener. But there are a few things that you need to check beforehand.

First, ensure that you have completely dry hair. Flat ironing will only damage if your hair isn’t completely dry. And if you have a heat protectant available, put it on your straightener.

If you don’t have short hair, then you should separate your hair into one-inch sections. Otherwise, you will have a lot of trouble during the straightening process. This is especially true for curly hair.

You might need to straighten a dime-sized amount at a time for curly hair. Because straightening a big portion of curly hair at a time can be a disaster.

Step 7: Straighten Your Hair

Set your straightener to the lowest heat setting and start to straighten each section of your hair. The temperature shouldn’t be over 350 degrees Fahrenheit. Next, proceed with the heating following any straightening methods.

I recommend going with the chase method. This method is quite simple and easy. You just need to use your brush and heater in a synchronized manner at a slow and steady pace until you get that perfectly smooth hair.

Make sure to work in a small section. Also, never use a comb for the straightening process as it can cause too much static on the hair.

Focus on the split ends; only here can you increase the heat slightly but don’t go over 400 degrees Fahrenheit.

Once you are done, you should have near-perfect straightened hair.

Step 8: Final Touch

Finish the straightening process with any styling product you want to use on your hair. Just make sure that it doesn’t have any adverse effects. Normally, I would suggest going for sprays, but oil or cream can be used for thicker hair.

There you have it. These are all the steps you need and my top recommended products for achieving frizz-free straight hair that lasts for days.

Why Does Straight Hair Turn Frizzy?

You can’t fix frizzy hair if you don’t know why it’s frizzy in the first place.

So let’s find out why …

Raised and Damaged Cuticles

The main reason for frizzy hair is the cuticle layer. If you look closely at a strand of frizzy hair, you will find that the cuticles are raised and damaged.

Hair cuticles get damaged for multiple reasons. The most common ones are an external force, aging, overuse of chemicals, environmental effects, and more.

No matter the reason, if your hair cuticles are damaged, your hair will end up frizzy in no time.

Humidity in the Air

Another contributing factor to frizz is humidity. Excess moisture must go somewhere in high humidity, and our hair becomes the perfect host.

When the extra moisture enters our hair, it expands the cells, which forces the cuticle layer to buckle and lose its shape.

This also depends on your hair porosity or how much moisture your hair can take and retain. The higher the porosity level, the worse the frizziness will be.

Going Overboard with Heat Styling Tools

Chemical Components in the Hair

Using too many chemical products like dyes, gels, or bleaching can take its toll on your hair, leading to unhealthy and compromized hair.
