Whether you want to straighten your hair for an upcoming special event or you just want to switch up your regular 'do, knowing how to straighten your hair so it lasts all day is key.

Depending on your hair type, you might find it drops back into its natural state after a few hours, which is not ideal.

But luckily, we've got a few tips and tricks to help you achieve sleek, straight locks that'll stay put until you hit the hay. We've put everything we know into a simple step-by-step guide that you can follow along with from home.

Different Ways to Straighten Men's Hair

Before we get stuck in, know that you have a few different options when it comes to straightening your hair. The most common methods include using a flat iron, blow dryer, or chemical treatments.

If you're not familiar with these techniques, we'll break them down for you and recommend which one might be best suited for your hair type.

#1 Flat Ironing

A flat iron – or straightener as most of us know it – is one of the easiest and quickest ways to get hair straight for men. These tools have plates that heat up, which you clamp down on sections of hair to smooth out any kinks or curls.

The heat from the flat iron breaks down the hydrogen bonds in your hair, temporarily changing the structure and allowing it to be straightened. Because of this, flat irons work best on just about any hair type and length.

If you have very thick or curly hair, it may take a few passes with the flat iron to fully straighten your hair, so working on small sections at a time can be helpful.

You can also adjust the heat settings on your flat iron to find what works best for your hair type, but avoid using maximum heat as it can cause damage, like split ends and dryness.

Using a heat protectant before taking the flat iron to your hair is also important, as it creates a barrier between the heat and your hair, preventing potential damage.

#2 Blow Drying

Using a blow dryer is another popular method for straightening hair. A bit like flat irons, blow dryers also use heat to manipulate and smooth out the hair.

This is a bit more tricky than using a flat iron, as you need to angle the blow dryer downwards while brushing your hair in a downward motion with a round brush.

If you have fluffy hair, you might want to avoid this method as it can create even more volume. In this case, a flat iron will be your best bet. But for those with thin or wavy hair , blow drying can be a great option for achieving straight locks.

Again, you'll want to use some sort of heat protectant before blow drying to protect your hair from heat damage.

#3 Chemical Straightening

If you're looking for a more permanent solution to straightening your hair, chemical straightening may be an option worth considering, but you should get this done at a salon by a professional.

Chemical straightening involves using chemicals to break down the bonds in your hair, allowing it to be reshaped into a straighter form.

There are different types of chemical straightening treatments available, so make sure to consult with your stylist to determine which one is best for your hair type.

Keep in mind that chemical straightening can be damaging to your hair, so it's important to properly care for and maintain your locks afterwards. This may include using deep conditioning treatments, avoiding heat styling tools, and using hair products specifically designed for chemically treated hair.

#4 Natural Remedies

If you want to avoid the heat and chemicals altogether, there are several natural remedies that can help to straighten your hair. These methods may take longer to achieve results, but they can be gentler on your locks and overall health.

Egg and oil is a classic DIY straightening treatment

The protein in eggs can help to strengthen and smooth the hair, while the oil adds moisture and shine. You can mix one beaten egg with a tablespoon of olive or coconut oil and apply it to your dry hair. Leave it on for 30-45 minutes before rinsing out.

Other popular natural treatments include coconut milk, aloe vera gel, and honey. These ingredients can help to nourish and hydrate the hair while promoting a straighter appearance.

It's important to note that these methods may not provide the same level of straightness as heat or chemical treatments, but they can help to improve the overall health and appearance of your hair.

What is the Best Way to Straighten Men's Hair?

If we put our two pennies in, we would recommend either flat ironing or blow drying for the easiest and longest-lasting method for straightening men's hair.

Chemical treatments are not the healthiest option and can lead to damage, so we suggest avoiding these if possible. And while natural remedies can provide some straightening effects, they may not be as effective as heat styling.

With heat styling tools, such as flat irons or blow dryers, it's simple to achieve straight hair and doesn't take a whole lot of time. Just be sure to use heat protectant products before applying any heat to your hair, and be wary of the temperature to avoid damage.

They're also pretty effective for all hair types, so minimal faffing about is required.

How to Straighten Men's Hair Using a Flat Iron

With that in mind, we're going to walk you through the steps of straightening men's hair using a flat iron. There's not a lot to it, but a few key tips can make all the difference in achieving straight strands that last all day.

Step 1: Wash Your Hair

First things first, always start with clean hair . Clean hair helps to ensure the straightening process goes smoothly and without any excess oil or product buildup interfering.

Use a good-quality shampoo to cleanse your hair and scalp, and follow up with a conditioner to keep your strands hydrated.

The products you use in this step are just as important as the tools you'll be using later on, so choose wisely. If you want to add extra volume to your hairstyle, a volumising shampoo and conditioner can help give your hair a lift.

Our Thickening Shampoo & Conditioner Duo does exactly that, creating thicker and fuller strands from root to tip.

Each formulation contains strengthening proteins and nutrients, such as Vitamin B3, Wheat Protein, and Aloe Leaf, to fortify and nourish your hair.

Plus, with clinically proven ingredients that prevent male pattern hair loss by blocking DHT, our duo is the perfect choice for those looking to maintain a healthy head of hair, all while adding volume.

You won't get the same results from a 2-in-1 shampoo and conditioner, as these typically don't have the added ingredients that specifically target volume. So be sure to start your hair routine with a shampoo and conditioner that really cares for your hair.

Step 2: Let Your Hair Dry

After washing, you'll want your hair to be completely dry before styling it. You shouldn't apply hot flat irons to wet or damp hair because this can cause damage and breakage.

Instead, let your hair air dry or use a blow dryer on a low heat setting.

Step 3: Section Out Your Hair

If you have particularly thick hair, you'll find that sectioning your mop will ensure you get to all your hair and don't miss any sections (especially those pieces underneath).

You can use small elastic bands or hair clips to hold each section in place as you work your way through styling.

Split your hair into around four or five sections, depending on the thickness of your hair.

Step 4: Protect Your Hair

Switch your straightening tool on and set it to a medium heat, ensuring it's not too hot to avoid damaging your hair. We recommend 180-200 degrees Celsius for most hair types.

Before you start straightening, apply a heat protectant product to your hair. You can find these products in the form of sprays, serums, or creams.

Step 5: Straighten Your Hair

Starting with the bottom sections, clamp your straightening tool as close to the roots of your hair as possible without burning yourself.

Slowly and smoothly glide the tool down the section of hair, making sure to keep the tool moving at a steady pace.

Repeat this process on each of the sections you divided your hair into. Make sure to take your time and not rush, as this will ensure that your hair is evenly straightened.

Step 6: Apply a Hold Product

Once you're satisfied you've straightened all of your hair, apply a hold product to keep the style in place and prevent it from frizzing up or losing its shape.

Our Hybrid Hair styling compound works really well for this, as it provides a strong hold without weighing your hair down. It combines all the good properties of a hair clay and wax, using Icelandic Bentonite Clay for maximum hold and volume alongside Organic British Beeswax to smooth and nourish your hair.

Simply apply a small amount to your palms and work the product through your hair, focusing on the ends and any particularly unruly sections.

How to Straighten Men's Hair Using a Blow Dryer

If you're more taken to using a blow dryer to straighten your hair, the process is just as simple and effective.

Assuming you've already washed your hair at this point, here's what you need to do:

  1. Start by towel-drying your hair until it is damp but not dripping wet.

  2. Apply a heat protectant to your hair to prevent damage from the blow dryer.

  3. Use a comb to part your hair in sections, starting at the back and working your way up to the front. Tipping your head upside down and blow drying will help add volume to your hair.

  4. Take a section of hair and wrap it around a round brush.

  5. Using the blow dryer on medium heat and high speed, aim the nozzle towards the hair and brush downwards, following the brush with the dryer. It's important to keep the dryer moving to avoid overheating one area.

  6. Repeat this process until all sections of your hair are dry and straightened.

  7. Once your hair is dry, use a hold product, like Hybrid Hair, to keep your straight stands in place.

If you have any particularly frizzy or fluffy areas, you can use a flat iron to smooth them out, too.

Summary: The Best Way to Get Straight Hair for Men

Flat ironing and blow drying are two of the easiest and most effective ways to straighten hair for men, and you don't have to be a professional stylist to do it. By following these simple steps and using the right products, you can achieve sleek and straight hair that’ll last throughout the day.

Why is it Difficult to Straighten My Hair?

If you have thick or coarse hair, it can be more difficult to straighten because the texture of your hair makes it more resistant to styling.

You might need to try an alternative method to the one you're currently using, such as using a flat iron or considering a keratin treatment to help straighten your hair more easily.

How Can I Straighten My Hair Without a Straightener?

A blow dryer can work just as well as a flat iron for straightening hair. However, if you're trying to avoid any sort of heat styling, natural methods, such as oil treatments, can help tame and straighten your locks. Popular options include coconut oil, argan oil, and grapeseed oil.

How Do I Stop My Hair from Curling?

Using a styling product to hold your hair in place can help prevent it from curling up and maintaining its straightness. A hair wax or clay are good choices, but we recommend opting for a hybrid styling compound that combines both wax and clay for maximum hold.

Hybrid Hair has incredible hold and flexibility, making it perfect for keeping your hair sleek and straight all day long. It also works to nourish and restore your hair, so you'll be encouraging healthy hair while maintaining your desired style.

How Can I Make My Thick Hair Straight?

When using a flat iron, make sure you section your hair out into small pieces so you can target each section effectively. Work on one area of your mop at a time, and use a slightly higher heat setting if your hair is particularly unruly (never forgoing heat protectant spray, of course).

Also, don't move the straighteners too quickly – take your time and make sure each section is straight before moving on to the next.
