What is a Hair Diffuser

Most people are wondering what is a hair diffuser and what is it used for? We all know that drying hair in a hurry or in the months of winter can be a real pain, especially when you’ve long, curly, or wavy hair. But, there’s always a solution for every problem. You can make your life simpler and style your natural curls easily by using a hair diffuser.

A hair diffuser helps in evenly drying your hair and the best part is that you can get stunning hairstyles in just a matter of minutes. If you are new to the world of hairstyling tools, let us dive into understanding what exactly is a hair diffuser and how you can use it to style your hair.

What is a Hair Diffuser?

A hair diffuser is basically an adjustable attachment that goes on your blow dryer. It has a large bowl-shaped head that usually has finger-like projections to help in evenly distributing and dispersing air that comes out from the hairdryer.

Using a blow dryer directly on your tresses can make them unmanageable and the pressure of the air can also damage your hair. But, you can reduce the impact of the air pressure while using a hair diffuser.

It gently disperses air into your strands without disturbing your natural hair pattern, making them look more voluminous and frizz-free. Hair diffusers are commonly used for curly and wavy hair as it makes styling them a lot easier. They help in defining your curls and giving a gorgeous shine without damaging your hairstyle or ruining those natural curls.

What is the Difference between a Hair Dryer and a Hair Diffuser?

A hair dryer or blow dryer is an electrical device that is primarily used to dry hair and it can also be used for hair styling. It has a heating coil with different heat levels that you can adjust on the dryer to evaporate water from wet hair.

Whereas, a hair diffuser is something that you attach to a hairdryer. It disperses air through a wider base thereby preventing the concentration of heat on one particular area.

Hair diffusers allow heat to be distributed evenly and on a much larger area. Hence, it is best to always use hair diffusers on curly and wavy hair to speed up drying time. Furthermore, hair diffusers can give you those shiny, bouncy, and beautiful curls without damaging your hair.

Is a Diffuser Bad for Your Hair?

It is not true that diffusers are bad for your hair. However, if you are a first-timer, then using a hair diffuser can seem like a difficult task. What matters when you are using a hair diffuser is that you need to learn the method of doing it right. Otherwise, there are chances that you might end up damaging your precious tresses from the heat.

Things to Remember While Using a Hair Diffuser

1. Use Low Heat

The most important thing that you need to remember is – do not use hair diffusers in a high heat setting. Even though the heat is dispersed evenly, hot air can lead to hair-thinning and frizzy hair.

2. Diffuse Hair in Sections

Move the diffuser around in regular intervals, for instance, every ten to fifteen seconds because lingering heat on a particular section can damage your hair by removing its moisture content. Avoid using hair diffusers on a daily basis, but if you have to then always use them in a low heat setting.

3. Repositioning

Don’t diffuse air directly into your curls, divide your hair into sections and gently drop your hair in the cup of the diffuser. Hold it for a few seconds before moving and repositioning the diffuser to a different section of the hair.

4. Do Not Use a Diffuser Straight Out of the Shower

Towel dries your hair gently, do not use the diffuser on soaking wet hair.

5. Don’t Go All the Way

Once your hair is 75% to 80% dry, stop using the diffuser and let your hair air dry. Do not play with your curls or run your fingers in your hair once you are done styling. Leave them alone to prevent disturbing the shape.

6. Hairspray

Always use a heat protectant, like hair serum, a nourishing cream, or hair spray before you use any hair styling tools to prevent damage. By doing this, you will not only protect your hair from the heat but also achieve shiny, healthy-looking hair.

If you are attempting hair diffusion for the first time, then do not fret. It will take some time and practice till you ace it. All you need to do is pay attention to these little things and you’ll end up with results that you are expecting. Now, let us find out the different types of hair diffusers available in the market.

How to Use a Diffuser on Curly Hair?

To keep your curls sleek and smooth, let us go through a step-by-step approach to follow during and after the shower.

1. Hydrate and Condition Your Hair After Rinsing with Shampoo.

Leave the conditioner in for a few minutes and rinse with cool or cold water to close the cuticles and the pores on your scalp. This will prevent drying and keep your hair moisturized.

2. Gently Squeeze and Remove Excess Water from Your Hair with a Towel.

Do not immediately use a blow dryer on wet hair, let them dry a bit.

3. Nourish Your Hair Before Drying

Use a hair styling cream, a nourishing milk conditioner, or mousse before you blowdry your hair.

4. Use the Diffuser

Now comes the part where you will use the diffuser. For curly hair, use a wide cup-shaped diffuser and attach it to your blow dryer.

5. Set the Heat Level to Warm, Cool, or Low

In this part, as we have already discussed, refrain from using high heat as it will only result in drying out your hair and making them frizzy.

6. Part Your Hair

Part your hair into sections, flip them and just drop the edges of the hair in the cupholder. Then move on to the next section of your hair. Start from the edges and then move on to the top of the head until your hair is almost dry.

7. Finish with Hair Serum

Finish off the look with a hair serum for gorgeous and bouncy curls.

How to Use a Diffuser on Straight and Wavy Hair?

Hair diffusers are not designed only for curly hair. Of course, drying your curls and retaining their shape is easier with a diffuser, but who says you cannot use a diffuser on straight and wavy hair?

The first few steps will be almost the same as for curly hair with a few tweaks here and there. Only the method of using the diffuser may vary for different types of hair.

Steps for Straight Hair

Naturally, straight hair usually does not need a diffuser but you can use it to maintain the shape and promote volume. You can also use a hair diffuser on your straight hair to get beautiful beachy waves.

  1. Wash and condition your hair and dry it with a microfiber towel or a T-shirt.
  2. Use a leave-in conditioner or a gel to detangle and retain the shape of your hair.
  3. Set your blow dryer to a medium or low heat level. Then use a diffuser that has small prongs on it. This way, you can slowly move from one section to another while gently massaging your hair and scalp.
  4. You can use your fingers or a brush to detangle or separate the hair while diffusing. Blow-dry at a 90-degree angle starting from the roots and move down slowly in a circular motion.
  5. To add more volume, you can flip your hair upside down and cup your hair in the diffuser for a few seconds.
  6. Once the hair is almost dry, use a hairspray to add volume and shine.

Steps for Wavy Hair

Whether you have naturally wavy hair or you are going for the beach waves hairstyle, a diffuser can help you achieve that perfect look.

  1. Start with washed hair that is dried just enough.
  2. Smoothen your hair with a leave-in conditioner or hair milk.
  3. Apply a serum or a cream and spread it evenly through your hair.
  4. Scrunch your hair with fingers till you can see a wavy pattern.
  5. Now, use the diffuser hairdryer and place the ends of your hair into the cup. Slowly lift the diffuser and bring it close to your scalp.
  6. Set the heat level to low, turn on the diffuser, and let your hair dry for a minute or two before you move on to the next section.
  7. When your hair is almost dry, turn off the dryer and mist your hair with a hair spray or gently rub in a nourishing mousse to finish off the look.


When you have a hair diffuser, you don’t need to rush to a salon to achieve those well-defined glossy curls. This is one of the most important perks of using a diffuser as you can style your hair from the comfort of your home.

Also, it doesn’t matter if your hair is curly, straight, long, wavy, or short, a diffuser can be used on all hair types. It helps in minimizing heat damage and reducing the risk of losing the natural texture of your hair. Go on now, buy a hair diffuser and flaunt your beautifully soft and stunningly styled tresses!
