If your hair straightener temperature is not working, the most common causes are a faulty thermostat, a broken heating element, or a loose power connection. Understanding the root cause helps you decide whether to attempt a repair or replace the tool. In many cases, simple cleaning or checking the power cord can solve the problem.
Pros
- Nutrient-infused plates actually work to improve hair health and shine, not just marketing
- Fast heat-up time and quick straightening means styling takes half the time of standard irons
- Works exceptionally well on thick, curly, and frizzy hair types that need extra power
- Adjustable temperature controls allow customization for different hair textures and protection
- Auto shut-off safety feature provides peace of mind for daily users
Cons
- 1-inch plate width may be too narrow for very thick or long hair, requiring more passes
- Wider plate design makes reaching roots near the scalp more difficult
- Auto shut-off timing is not specified, which could be a concern for forgetful users
The Remington Shine Therapy is a 1-inch ceramic hair straightener designed for anyone struggling with frizz, thickness, or naturally curly hair. It combines professional-grade technology with nutrient-infused plates to deliver salon-quality results at home, making it an excellent choice for daily users and frequent travelers alike.
What sets this straightener apart is its keratin and argan oil infused ceramic plates. Unlike typical flat irons that simply apply heat, these nutrient-rich plates actively condition hair while straightening, leaving strands noticeably shinier and smoother. The iron heats up in seconds and glides effortlessly through hair without pulling or snagging, straightening thick or curly hair in just a few passes. Users consistently report that results look like they just stepped out of an expensive salon, with shine that lasts all day.
The design prioritizes both functionality and convenience. The lightweight, compact 1-inch plate is ideal for travel and everyday styling, while adjustable temperature settings accommodate different hair types and allow users to prioritize hair health. An auto shut-off safety feature provides added protection against accidental burns, a valuable feature for busy lifestyles.
The main limitation is the 1-inch plate width, which works best for medium to thick hair but may require extra passes on very thick or long hair. Additionally, the narrower plate design makes accessing roots near the scalp slightly more challenging than wider 2-inch models, though this is a minor trade-off for the straightener's portability.
Overall, the Remington Shine Therapy delivers exceptional value for anyone seeking professional straightening results with genuine hair conditioning benefits. Its proven performance on challenging hair types, combined with affordable pricing and practical features, makes it a top choice in the hair straightening category.

Faulty Thermostat
The thermostat inside your straightener regulates the heat by turning the heating element on and off. When it fails, the device may not reach the set temperature, or it may overheat and then shut off prematurely. This is one of the most common electronic failures in hair straighteners.
You can sometimes test the thermostat with a multimeter, but that requires opening the device. If the straightener is under warranty, contact the manufacturer. Otherwise, replacement is often more cost-effective than repair.
Broken Heating Element
The heating element is the core component that generates heat. It can break due to physical impact, age, or repeated thermal stress. A broken element typically results in no heat at all, or heat only on one side of the plates.
If you suspect a broken heating element and the straightener is not under warranty, it is usually time to replace the unit. Repairing a heating element is rarely practical for home users.
Loose Power Connections
Loose wiring inside the straightener or a damaged power cord can interrupt the electrical supply. This can cause the device to heat intermittently or not at all. Check the cord for visible damage, and wiggle the cable near the base to see if the heat changes.
If the cord is damaged, replacement may be possible if the cord is detachable. For fixed cords, the entire unit might need replacement. Internal loose connections require professional repair or replacement.
Dirty or Residue-Covered Plates
Hair product residue, oils, and dirt can build up on the plates over time. This layer acts as an insulator, preventing the heat from transferring to your hair. The straightener may still get hot, but it won’t feel as hot on your strands.
Cleaning the plates with a damp cloth or a specialized cleaner can restore proper heat transfer. This is the easiest fix to try first.
Auto Shut-Off Feature
Many modern straighteners include an automatic shut-off feature that turns the device off after a period of inactivity, usually 30 to 60 minutes. If you set the straightener down and it powers off, it may not be a malfunction. Simply press the power button to restart.
Some models also have a standby mode that reduces heat after a few minutes. Check the user manual for your specific model to understand its behavior.
Voltage Mismatch
Using a hair straightener designed for a different voltage than your local power supply can cause it to operate at reduced heat or not at all. Most straighteners are either 110-120V or 220-240V. Dual-voltage models are available, but if yours is not, you may need a voltage converter.
Check the voltage rating on the straightener’s label. If you are traveling, this is a common cause of temperature issues.
Age and Wear
Over years of use, internal components degrade. The heating element may lose efficiency, the thermostat may drift, and connections may corrode. If your straightener is several years old and suddenly stops heating properly, it may simply be at the end of its lifespan.
In this case, replacement is the most practical solution. Look for a model with positive reviews in your price range.
How to Fix a Hair Straightener Temperature Not Working
- Check the power cord for visible damage and test the outlet with another device.
- Clean the plates thoroughly with a soft cloth and isopropyl alcohol.
- Reset the auto shut-off by turning the straightener off and on again.
- Verify the voltage setting matches your local power supply.
- If the straightener still does not heat, the issue is likely internal (thermostat or heating element).
If dirty plates are the culprit, regular cleaning can restore heat transfer. For a step-by-step guide, see our article on how to clean hair styler attachments.

Frequently Asked Questions
Why does my hair straightener heat up then stop?
This often points to a faulty thermostat or a loose connection. The device may heat briefly then cut off as a safety mechanism. Check the cord and internal wiring, but if the problem persists, replacement is likely needed.
Why is my straightener not heating evenly?
Uneven heating usually indicates a damaged heating element or dirty plates. Cleaning the plates may help, but if the element is broken, you will need a new straightener. Also check for loose wiring on one side of the plates.
Can I repair a straightener with a broken thermostat?
Possibly, but it requires disassembly and soldering. Most users find it cheaper to replace the unit. If the straightener is still under warranty, contact the manufacturer first.
How do I know if the heating element is broken?
If the straightener shows no heat at all and the power cord is fine, the heating element is likely broken. You may also see an orange glow that quickly fades. In that case, replacement is the only option.
A hair straightener that doesn’t heat properly can often be fixed by checking the power source, cleaning the plates, or resetting the auto shut-off. If those steps fail, the issue is likely internal. For more troubleshooting on overheating, see our guide on hair styler overheating.
