What Is A Diffuser?

A diffuser is simply an attachment for a hairdryer. They function by dividing the jet of hot air coming out from a hairdryer into multiple, smaller jets of sir.

Their functionality can be compared to the phenomenon of showerheads, where a single stream of water gets split up into multiple smaller streams of water. This results in lower pressure and diffused flow of air from the hairdryer. 


Strong hot air currents from a hairdryer can result in damage to the hair, most commonly causing frizziness. They are also damaging to curls as well as straightened hair.

Tips For Selecting The Best Hair Diffuser

When it comes to hairdryers and diffusers, there are a ton of options available in the market. They vary based on different properties, and one should carefully compare the different models before selecting a particular option that suits their hair care needs. 


  1. The Power Settings: The first thing to consider while choosing a hairdryer or diffuser is to find out their power settings. Understanding power settings are relatively straightforward.

    Higher power settings mean your blow dryer and diffuser will dry out your hair much quicker. Models belonging to a higher wattage, such as the 1800watts or a higher model is recommended, especially if one has thin hair.

    The lessening of the drying time means your hair gets exposed to the hot air for a lesser period, thus minimizing hair damage.


  2. Material: Another key factor to consider is the material from which the diffuser is made. Generally, professionals recommend ceramic or tourmaline models over other materials.

    This is due to their thermal properties and causes the equal distribution of the heated air. The thermal distributive property ensures less heat damage and quicker drying.


  3. Different Settings: It is ideally recommended that one chooses a hairdryer and diffuser that has multiple temperatures and airflow settings. This allows you to have greater freedom while styling your hair.

    A higher power setting can be used while initially drying the hair, while the last part of drying can be done under lower settings. Furthermore, it allows one to adapt to different settings for different hair types.


  4. Attachments: It is important to select a Hairdryer that allows attachments to be added to it. This is important for a hair diffuser to be used along with the hairdryer. 


The budget is something that is to be considered before buying a particular hair diffuser. However, when it comes to a hair diffuser, a higher price doesn’t always equate to higher efficiency. It is best to look through different options and their features before selecting a particular model. 


Hair diffuser is an essential tool for everyday hair care. A hair diffuser allows your straight hair to be kept smooth and frizz-free while preventing any form of heat damage due to the use of a hairdryer.

By following the above-discussed steps and selecting a well-suited diffuser, one can get smooth and silky hair, and keep damaged frizzy hair at bay.
