Since 1989, his passion for innovation has led him to create groundbreaking hair tools that minimize stress on the hair while delivering flawless results. From the iconic Rootpermer and Wellformer of the ’90s to the global hit Babyliss Curl Secret, Alfredo’s mission remains the same—developing tools that protect hair health without compromising style.
The best temperature for heat styling will depend on your hair type, but the golden rule is ‘low and slow’
For severely damaged hair, start at 130–160°C. Thick or coarse hair can withstand up to 220°C.
Knowing your hair type will help you style it more safely and take better care of it. With that in mind, we’ve created a quick-look chart to partner with our Heat & Tension Quiz.
Product build-up and poor sectioning often lead us to use unnecessarily high heat because we feel the straighteners aren’t working. Always clean your straighteners before or after use, depending on the condition and frequency of use. Proper sectioning is also essential to ensure the best results from your heated styling tools.
We always recommend starting at the lowest heat setting and working your way up if necessary. This is because the higher the heat, the higher the risk of damage.
Applying intense heat to your hair can dry it out and increase the risk of breakage. It can also make your hair rough and frizzy - the opposite of the sleek smoothness you are trying to achieve.
We tend to jump straight to turning up the heat if we feel our straighteners aren’t working. But there could be another issue.
For example, if you need more than three passes to straighten your hair, you probably haven’t prepped or sectioned it properly.
Here are a few signs you need to reduce the temperature:
To straighten your hair on a lower heat:
If your hair is coloured, it may be more porous, meaning it is more susceptible to drying frizz and cuticle damage.
Grey hair can be fine in density but coarse or wiry in texture. This makes it more difficult to correctly judge the temperature you need.
Fine/thinning hair needs extra care when heat styling.
If your hair is already damaged, be careful not to damage it further with intense heat.
The KEEO Genius Pro+ is designed to care for your hair while it styles. Hair looks and feels healthier after only 30 days. This might sound like a big claim, but we’ve got the science to back it up.
Trichologist Kate Holden explains:
“Traditional styling tools can exert intense mechanical tension and high heat, both of which can aggravate fragile strands and accelerate breakage. What’s unique about KEEO is that it gives users control — not just over temperature, but over tension, too. The contoured plates glide through the hair, reducing stress on the fibre by up to 70%. For those with vulnerable, hormonally affected, or post-shedding hair, this kind of technology offers a gentler, more considered way to style — without compromising on results.
“As a hair health expert, I can tell that the Genius Pro+ wasn’t just made to style hair - it was made to protect it too.”
Using the correct temperature and tension for your hair type and condition will minimise damage and help you achieve the healthy, beautiful and perfectly styled hair you crave.
Remember to dry and prep hair, use a heat protectant, and properly section before styling.
No matter your hair type, the KEEO Genius Pro+ is gentler, for effortless style without stress and damage.
If you aren’t sure about your hair type, start with the lowest setting and work your way up, if necessary. You can find out more about hair types and curl patterns in our previous blog.
We don’t recommend doing one pass at a high heat. It is healthier for your hair to do a few slow passes at a lower temperature than it is to do one fast pass at a high heat.
There are a few reasons why your hair may still feel frizzy after straightening:
To combat frizz after straightening:
Your straightener plates should be gently cleaned regularly, depending on how often you use the device and which products you use with it.
A quick frequency guide:
Make sure the straightener has been switched off and is mostly cool (but not cold) before cleaning.
Dirty plates can increase the risk of damaging your hair because:
Dirty plates may harbour bacteria that can irritate your scalp.
Both are important. Heat protectant provides a barrier between the hair and the heat. This thin protective film prevents the heat from penetrating the hair shaft too quickly and helps distribute the heat evenly. It also locks moisture into the hair cuticle to prevent the heat from drying out your hair.
However, the hotter the temperature, the faster the heat will penetrate. If your hair is wet or severely damaged, it can ‘fry’ almost instantly.
