We all love our hot styling tools, whether it’s a hairdryer, curling iron, or straightener. But with heat styling comes heat-damaged hair: split ends, dry and dull strands, and hair breakage.
“Excessive heat over a prolonged period will cause irreversible heat damage,” says Maya.
How heat damages hair
Maya explains “Hair is made up of a protein called keratin. High temperatures can weaken and break down the protein bonds leading to permanent structural damage.”
Maya adds “Heat damage is cumulative. Regularly using tools at high temperatures increases the changes in the protein bonds and moisture levels of each strand. Eventually, those bonds are broken and can’t be fixed.”
Fine and thin hair is generally more vulnerable to heat damage as it has less natural protection. But thick and coarse hair isn’t immune, especially when subjected to high heat frequently or for extended periods.
Hot tools, cool tricks
The good news is you don’t need to give up your styling tools entirely. Here are our five practical tips you can use to minimise heat damage:
#1. Don’t skip heat protectant
Before using any heated tools (including a hair dryer), always apply a heat-protectant product. This will create a protective barrier that seals in moisture and helps stop the hair shaft from drying out, keeping hair looking shiny and healthy.
Maya adds “I particularly like Kerastase Lotion Thermique as its ultra-lightweight consistency is easy to distribute evenly through the hair, it’s absorbed within seconds and doesn’t leave a residue behind.”
#2. Invest in quality styling tools
High-quality heat styling tools often have a more even heat distribution, reducing the chances of ‘hot spots’ that can severely damage hair.
They usually have adjustable heat settings too, so you start with a low temperature and only increase if necessary.
Maya cautions, “And avoid using your tools on the same section of hair more than once because it can cause damage to your hair shafts.”
#3. Avoid styling wet hair
Wet hair is more susceptible to heat damage as the cuticle (outer layer of your hair) is raised, exposing the inner structures of the hair to the intense heat. So always ensure your hair is 70-80% dry before using heat tools, advises Maya.
#4. Give frazzled locks a break
Heat damage is cumulative and continual heat styling will progressively weaken your hair. So it’s important to try to incorporate heat-free days in your haircare routine.
Air drying your hair when you can and use dry shampoo once a week if possible. Plus you can explore alternative ways of styling like braids, updos, or hair accessories that do not require heated tools.
#5. Condition. Condition. Condition.
Deep conditioning treatments restore essential moisture and nutrients to your hair, combating dryness and brittleness from heat styling. Regularly using hair masks or deep conditioners like our Kerastase Fusio Doses can significantly help restore and maintain hair health.
#6. Book regular trims
Even with these precautions, some degree of heat damage is almost inevitable. That’s why it’s crucial to get regular maintenance cuts every 6-8 weeks to remove any damaged or split ends and keep your hair looking its best.
As always, remember that everyone’s hair is unique, so do ask your stylist for advice, tips and recommendations – we love to help.
