12 Best Bonnet Hair Dryers for Heat Styling and Deep Conditioning

With over 15,000 Amazon reviews and 4.4 star rating, this dryer is a popular choice. It features two heat settings, adjustable height and is compact enough for easy storage.

"The bonnet was wide enough and deep enough to accommodate my head with rollers," one Amazon reviewer wrote. "As for the arm, I was pleasantly surprised by the adjustments! It has at least three (probably more like five) distinct levels at which a person can position it which I think is good enough for a portable collapsible standing dryer such as this one. Finally, it is quite lightweight and can easily be carried about from place to place."

At just $10, this hair dryer attachment is the most affordable on our list. Made with waterproof plastic, it comes with a storage bag and features a universal hose that the brand claims will fit most blow dryers.

Reviewers love that it is compact and includes an adjustable chin strap. "The chin strap and the longer hose were game changers for me," one Amazon reviewer noted. "I no longer have to hold it in place, which keeps my hands free and the longer hose allows me more mobility in the room. Be careful because it gets hot. I recommend medium and low settings only for this one."

Bring the salon experience into the comfort of your own home with this professional hooded floor hair dryer. This one includes a 60-minute timer, swivel hood and heat adjustment of up to 167°F.

According to Amazon reviewers, it works well on a variety of hair types and allows for quick drying. "I have very thick, very curly hair that when wet hits my shoulder blades, when dry sits just at the top of my shoulders," one Amazon reviewer wrote. "Using a professional 1875W hairdryer with a diffuser normally takes about 45 minutes to completely dry my hair. Using this, my hair was dry in 10 minutes (who can't use an extra 35 minutes in the morning!!!)."

With over 11,000 5-star ratings on Amazon, reviewers say hey love this hood attachment for travel, since it easily packs up into an included storage pouch.

They also praise its comfortable fit and the towel-like heat protection headband that covers the neck, ears and forehead. It comes in five colors (black, purple, gold, rose gold and black), features internal ventilation holes designed for even heat distribution and is easy to clean. Just note that some reviewers warn that the hose can sometimes slip from the blow dryer it's attached to.

If you're looking for a soft bonnet dryer option, this one comes with four heat settings, a bonnet storage compartment and six-foot cord for increased mobility. Reviewers say that the cap is about the thickness of a shower cap, making it easy to store inside the dryer. They also say it heats up quickly. "Really convenient storage space saver like a small card case; can slide in a drawer or bathroom cabinet," one reviewer noted.

Hair dryer attachments are underrated when it comes to saving space. This specific one comes in three color options (purple, black and blue), and is comfortable to wear as it features a chin strap and drawstring headband. It also has an elastic strap designed to keep the attachment secure on your blow dryer and a compact bag for easy storage. Many reviewers also report using it as an alternative to a diffuser for quicker drying time, though they warned that using the highest heat setting for an extended period of time could melt the cap.

Designed to minimize frizz when heat styling, this hard hooded dryer features an XXL hood, adjustable neck and four heat settings. According to reviewers, it heats up quickly and dries hair fast.

"I ended up liking this one better and my stand dryer was 3x as much. It has tons of heat that activates and sets my curls without blowing it all around, literally no frizz, just beautiful bouncy curls. It's truly amazing! Highly recommend for curly hair," one Amazon reviewer wrote.

While technically not a hair dryer, this thermal heat cap can help when it comes to deep conditioning your hair. Instead of fumbling with cords, this portable cap is designed to retain heat after you warm it in a microwave.

"I cannot express how surprised and satisfied I am with my purchase," one Amazon reviewer wrote. "The flaxseed-linseed filler heats quickly and evenly ... it’s well-made with a strong elastic edge and quality fabric; feels very comfortable, like a ski cap or hat; you can move about the house and almost forget you’re wearing it and it also looks good."

Another solid option for a soft bonnet hair dryer is this one from Conair. It comes with a hot air vent brush attachment, it is compact in size and features an adjustable hose that can be extended to become longer. Reviewers noted that after using the dryer they noticed that their hair felt "silky, soft and smooth."

Similar to the cap by Glow by Daye, this thermal cap works to heat hair for deep conditioning or oil treatments, but needs to be plugged into an outlet. It features 10 heat settings and three timer intervals (30, 45 and 60 minutes).

It also comes with additional plastic caps and is deep and wide enough for long and thick hair. "I do like this WAYYYY better than sitting under the hooded dryer for a deep conditioning process. It is convenient because it’s not big and noisy and it fits directly on your head," one reviewer wrote.

Reviewers say they love that this hard bonnet dryer was easy to set up and felt sturdy. It has three heat levels, built-in cord storage and an adjustable hood that fits most roller sizes.

However, some Amazon reviewers state that it may work better for those with heat sensitivity. "This hair dryer works perfectly. The heat isn't too hot on your head. It isn't very loud and it dried my hair perfectly," one reviewer wrote.

Users with long hair were fans of this attachment's extra large cap. "Works great for my long locs. [Dries] my locs all over and less time spent under the dryer; fits fairly well on my head too. Definitely happy that I bought it," an Amazon reviewer wrote.

It comes with a storage bag and long hose, though one reviewer noted that it did not fit over her blow dryer with a 3-inch diameter, so be sure to check if your blow dryer is compatible.
