Science says you might be doing it wrong… air drying your hair is causing more damage than blowdrying!
When hair is wet, the hair fibre will swell and become weaker. Hence prolonged exposure to water will mean more chance of damage to the hair since it is in this weakened state. Minimizing the time you allow it to be wet is a good idea, but you need to dry it in the right way so as not to cause more unnecessary damage.
When hair comes into contact with water it swells and the longer the swelling goes for, the more pressure it puts on the delicate proteins that keep hair intact, which can lead to further damage.
ghd scientist and Vice President of Smart Devices, Dr. Tim Moore, has come up with this formula:
Start by using a scrunching motion when towel drying; do not rub the towel across hair when wet, hair is weak so is broken more easily when wet
Spritz wet hair with the ghd heat protect spray; this provides an invisible barrier against everyday heat damage and provides cuticle protection, preventing vertical cracks inside the cuticle which fundamentally causes split ends and irreversible damage.
Use the ghd helios hairdryer and start on a lower heat setting; high temperatures can cause damage to wet hair so start at the lowest setting and very slowly increase the heat as the hair becomes drier.
When you start to feel the hair warm-up, that’s your signal to start to turn the heat up on your hairdryer to complete and set your style.
“You need to treat hair carefully when it is wet. Wet hair is weakened which means that it is easily broken and damaged by high temperatures. In fact, the denaturation temperature of hair drops when it is wet, so you must be careful when drying. Start by towel drying in a scrunching, circular motion, and before using a hairdryer, use a heat protect spray. Use the hairdryer on the lowest, cool setting so you don’t heat the hair above the denaturation temperature. As the hair dries, the temperature can be increased since the denaturation temperature increases – you can feel this while drying as the hair will suddenly start to warm up. You can then set your style using the high-temperature setting.” – DR TIM MOORE, ghd Vice President of Smart Devices
