Important Features To Consider

A hair diffuser should be able to evenly distribute the heat from your blowdryer, help enhance your natural curls and waves or straighten your hair. Here is what to consider when selecting a hair diffuser.

  • Bowl size. Hair diffusers come in all kinds of shapes and sizes. Some have larger bowls than others. The bowl size is relevant to the amount of air that is distributed throughout the hair. Diffusers with large bowls are more for curly hair, as the air that is distributed is done so through a wide bowl, helping to give definition to curls. Using the high heat and low air setting on your blowdryer will assure a tight curl pattern and no frizziness.
  • Spikes/fingers. These refer to the tips that protrude from the diffuser bowl. Different diffusers have different amounts of spikes. Sometimes spikes are referred to as “fingers.” The purpose of them is to hold your hair in its place while diffusing the air from the blowdryer throughout the hair.
  • Fit. It is integral to make certain before you purchase a diffuser to make sure that the diffuser itself is going to fit the hairdryer that you own. There are quite a few different universal diffusers out there that will fit almost any hairdryer out there. Measure the diameter of your hairdryer nozzle (in inches or centimeters, whichever is easiest for you), so then you will be able to purchase the correct diffuser for your blowdryer accordingly.
  • Strength. When looking for a diffuser, you may want to look for something that will withstand everyday use. You are going to want something that is going to be able to give you years of use. It is best to find a diffuser that is durable and can withstand the test of time.
  • Ease of use. Is the diffuser that you are thinking about purchasing easy to attach to your hairdryer? Find a hair diffuser that will be able to pop on and off with ease. That way you will not have to go through a hassle every day fighting to put a diffuser onto your hairdryer.

Frequently Asked Questions

What is a diffuser and how does it work?

A hair diffuser is an accessory that attaches to your existing hairdryer. It is meant to diffuse the hot and often harsh air from your blow dryer and “diffusing” the air throughout airholes that are built into the diffuser. It covers a wider area of hair and is often used to achieve tight, curly locks. There are different types of diffusers available for purchase. Some of them include diffusers for straight and wavy hair as well as curly hair.

Will a diffuser fit on any hairdryer?

Many hair diffusers are created to be universal, meaning that they will fit on almost any hairdryer. However, it would be a good idea to measure the diameter of the nozzle of your hairdryer to make sure the diffuser that you are planning to purchase will fit onto it. There are hairdryers on the market that do have differently shaped nozzles. Some taper into a flat shape, or an extra wide shape. In that case, you will have to search for a hair diffuser that will fit snugly onto the nozzle of your hairdryer.

Is a diffuser better for your hair?

By and far, diffusers are definitely a better way to dry your hair. With just the heat of a regular hairdryer, you are blowing air that is at a very high temperature onto your hair. Too much heat and your hair can become damaged. A diffuser is a great way to prevent such damage. Because a diffuser takes the air from your blowdryer and cools it, as well as spreading it around more evenly, there is no damage that is being done. So, most definitely, diffusers are a great styling tool for your hair. That, and it cuts down time spent drying your hair.

Is it better to air dry or diffuse curly hair?

This all depends on the type of curly hair that you have. If you have a fragile curl pattern, it may be better to air dry your hair. But if you have naturally wavy or curly hair and you want to amp up the volume, you will want to use a diffuser on your hair. Once you are finished washing your hair, you will want to towel dry it. Diffusing should be done on damp, but not soaking wet hair.
