What does heat styling do to your hair?

So I have been researching a lot about what heat actually does to your hair. During the summer I didn’t touch my hair with heat but as the months get cooler I find myself reaching for the heat tools a bit more plus my hair isn’t drying as quick as it did in the summer! Ive always know that heat isn’t amazing for your hair but I wanted to find a few more facts out so I have a justified reason to not use heat and to give me something to think about before I pick up the curler! All websites and articles where I found these bits of information will be linked at the bottom if you want to dig deeper.

  1. Researchers say early results are a bit inconclusive. It turns out that everyone’s hair is different and that there’s no exact temperature where hair straightening becomes hair damage. People with naturally curly hair can suffer more damage from heat irons than those with straight hair. Though heat tools do cause extreme thermal stress on your hair, with temps reaching as high as 200°C.
  2. So we have these things called ‘S-S or disulfide bonds’ within hair strands that give hair its strength along with protein cross-links, these can be permanently broken with high or excessive heat. Heat damage cannot be repaired. Heat styling weakens or breaks the keratin in your hair, which is responsible for the hairs shape. When looking to buy a new flat iron, look for ceramic or titanium irons with heat controls, so you are able to control the iron’s temperature.  This way you can start at a low setting and increase or decrease the temperature depending if you need to.
  3. No heat, does not equal hair growth. It’s all about moderation.  Minimal heat use can be beneficial for your hair but its all about what you do & how you care for your hair. Hair grows from the root, but obviously if your hair is damage at the ends and is breaking it may seem like your hair isn’t growing.
  4. One experience responsible for damage to hair is loss of moisture when using heat. Evaporation of the water molecules, in your hair, due to application of heat can alter the internal protein structure and change mechanical properties of individual hair strands. This can change curl patterns, cause frizz, and result in hair that is more prone to breaking & causes it to feel less soft.
  5. Rapid Water Loss – The extremely high temperatures encountered in heat use create intense conditions that can cause water to rapidly boil off from sites where it resides within the hair shaft. This rapid boiling can create voids in the hair structure and look like strings of bubbles within the strand. These burst through the cuticle, leaving spots in the hair, which lead to split ends and breakage, this leads to cracks in the cuticle as well, making the hair prone to more moisture loss and breakage. This type of damage is severe.
  6. High temperatures can cause oxidation of pigments found in hair, both naturally occurring ones and artificial hair colour. This fading is particularly pronounced in reds, auburns and lighter brunette shades

It was fun looking at websites to find out facts and dig a little deeper, its definitely something to think about when I’m next picking up the blow dryer. Though I don’t think I will completely stop using heat, I’m going to make sure I leave a couple of days + in-between uses.

Thank you for taking the time to read this!
