Why Do Electric Hot Combs Turn Off Automatically?

Electric hot combs are programmed to shut down automatically for your safety. Most hot combs have a built-in safety feature that turns off the heat after a certain amount of time to prevent overheating or accidental burns. This feature is especially important for hot combs with high heat settings, which can overheat more easily.

The automatic shut-off feature, in addition to preventing overheating, can help to conserve energy and extend the life of the hot comb. The hot comb will use less energy and may last longer before needing to be replaced if it is turned off when not in use.

Overall, the automatic shut-off feature is a safety feature that aids in the prevention of accidents and the extension of the lifespan of electric hot comb.

Many women are not able to make a flat iron their styling tool of choice due to the high temperatures of a flat iron turn their thin and sensitive hair to split ends quickly. This is one reason new hair brush straighteners “The Hot Brush” has become a sensation practically overnight for straightening hair.

You should definitely buy a hot brush straightener with an auto shut-off to avoid unnecessary risks of forgetting to turn off your brush.

Hair Brush Straighteners Important Characteristics

According to Meesh, Hair Product Analyst, “One of the most important feature of any styling tool is safety and having an auto shutoff.” Everything else is secondary. Safety is the primary concern. You do not want a product that is not well made and has your safety in mind.

  1. Brush Control: Now that being said some other very important features is control. You must be able to control the brush comfortable with one hand. You do not want a brush that is too heavy.
  2. Heat Settings: After that is heat settings. You want to be able to control the amount of heat being applied to your hair. Especially to keep from damaging your hair or if you already have damaged hair to keep it from getting even more damaged. Hair straighteners now days have precise temperature controls you can set to your hair type. For example for medium thick hair a temperature of 365 degrees is usually considered optimal. For thin hair you would most likely use a lower temperature of 300 degrees. And for real thick and curly hair a higher temperature is needed, usually 450 degrees.
  3. Brush Bristles: What is the best. Well that depends on your hair type. Nylon is best for sensitive scalps or hair that is not too thin. Some straighteners have bristles tipped with silicone balls or other materials. They can be more comfortable to your scalp.
  4. Ceramic or Titanium: Although a few use titanium, most straighteners will come with ceramic or tourmaline plates. Ceramic is going to be the best choice for delicate, fine or even color-treated hair. The ceramic heats very evenly and more slowly than tourmaline or titanium without any hot spots. In contrast, tourmaline and titanium heat up very quickly and can easily damage thin or sensitive hair. For thick hair, you can to use tourmaline or titanium. Tourmaline has the extra added advantage of producing 20 times more negative ions, making your hair moist, silky and reducing the frizz.

Examples Of Hair Brush Straighteners With Auto Shut Off

At the time of this writing the auto shut off times listed above was listed per the manufacture’s manual. Please do not rely on this website but make sure to read your product manual and follow the manufactures instructions. There are many other very good models with an auto shut off the ones I listed are my top ones. Which one you end up choosing is up to you.

Hair straighteners come in two basic types the “Flat/Paddle” and “Barrel Brush” style. They perform similar and both have ceramic or tourmaline plates containing bristles. Heat is generated by the plate and as the hair passes through the bristles negative ions are released the make your hair smoother and shiner. The barrel brush can have a fixed or rotating head. The head also straightens and adds shine to your hair. The way it works is that hot air is directed into the barrel and as it rotates it adds volume and shine to thin air. The biggest difference between the “Flat/Paddle” and the “Barrel” straightener is the barrel version can also curl hair as well as straighten.

Glamfields Heated MCH Hair Straightening Brush with 30 minute auto shut off

I love the 12 different heat settings on the Glamfields straightening brush. This gives you a wide range of options for your hair. In addition it has a 30 minute auto shut off which in my opinion is good. Nice big head works through hair fast. Heats up very fast. And lastly a 12 month warranty.

Hair Brush Straightener
Glamfields Heated MCH Hair Straightening Brush With 30 Minute Auto Shut Off


  • Heat settings: 12, from 250° to 450°, 40 seconds to 450°
  • Auto heat lock, 30 minute auto shutoff
  • LED temperature display, dual voltage (110V/220V)
  • Metal ceramic heater, negative-ion function
  • Features – Wide head, anti-scald tip, LED and swivel cord
  • Warranty: 12 months

Professional ceramic comb heats quickly, saves energy, is more durable, and longer lasting. Has Advanced MCH technology that can heat up within 30 to 40 seconds. Contains a wider and denser comb tooth head that dramatically decrease your straightening, styling and brush time. The wider and larger head is really a huge advantage for those who have long hair. With a larger head you are able to cut your styling time down by as much as 25% in some cases.

According to Stacey, Hair Research Analyst, “Negative ions are a big plus. The rich negative ions created by the electric hair brush can eliminate frizz, split ends, knot and add shine.” In addition, helps with the looks and hair quality of damaged hair. Makes it a smoother and give it a much healthier natural look and feel. This is a fantastic feature to have on a straightener however I wish they would have made an on off button. There are some time when negative ions are just not needed. In that case if this product had an off button you could just simply turn it off. Adding this would put the Glamfields Heated MCH straightener over the top. It’s already a great tool so this would just add icing to the cake, right?

Two big safety features I like are the Temperature lock function and the Auto Shut-off. The temperature lock function can prevent temperature changes from occurring unintentionally. And if no motions are detected, to ensure safety, auto shutdown occurs after 30mins. The reason why I like the temperature lock is is you have thin hair for example and you are using a lower heat setting then there is now way to accidentally hit the temperature button and go to a higher heat setting. This dramatically reduces the risk of you burning your hair. The other safety feature is the auto shut-off. If you forget to turn it off you have the piece of mind that it will turn off automatically. A very handy feature to have.

If you do not know what temperature to start with I suggest you start at the lowest temperature and work upward. Do not start at a random temperature! Most likely if you have fine, thin hair you are going to want to start at the lowest temperature setting. Try practicing. To make things easier I suggest starting with clean dry hair. Then once you get the hang of it and your are familiar with the brush your styling times will decrease.

The reason you should star with dry hair is because it will take much longer if your hair is damp. If you find you are losing your style after a few hours the try increasing the heat on your next style. Keep practicing till you have the right look. You will find out by practicing you will find the right temperature and the right speed at which you should move the brush through your hair to get the perfect results.

Another helpful tip is to always brush through your hair first before using a hot air brush. You want to make sure your hair is not tangled. And it has been combed or brushed thoroughly. This makes it much easier when working with the hot air brush. The last thing you want to do is to try to detangle your hair using the hot brush.

Also make sure your hands are clean and dry. You do not want to drop your hot air brush on the floor. This will totally destroy your brush. It can break the electronics inside. You may thing it’s OK after a drop but you may never know until something happens. If you have just applied a heat protector to your hair and your hands are not perfectly clean and dry take the time to wash and dry your hands before styling. If you get into this habit you will be so glad you did later.
