To reduce heat damage when blow-drying, blot your hair gently, let it partially air-dry when you have time, then finish with the dryer on its lowest effective heat setting. Hold it roughly 15 cm away and keep it moving. If you use a flat iron, wait until your hair is completely dry. [1] [2]
On a busy UAE morning, you may have just enough time to get your hair dry before heading out. Start with the setting and distance on the dryer you already own. Those are changes you can make on your next wash day.
How to blow-dry your hair with less heat
- Blot first. Wrap or gently press a soft towel or cotton T-shirt around your hair to absorb water. Give your hair a few minutes to air-dry if your schedule allows. [1] [3]
- Start on low heat. If your dryer has separate controls for airflow and temperature, check which switch controls the heat. Use the lowest setting that lets you dry your hair comfortably. [3]
- Leave a gap and keep moving. Aim for about 15 cm between the nozzle and your hair as a practical reference. Sweep across each section and move on once it feels dry. [2]
- Decide whether you need another hot tool. If you like the result after drying, you can skip the straightener. When you do flat-iron, use low or medium heat on completely dry hair and space out styling sessions. [1]
If you wear your curls natural, you can adapt the routine without brushing them out. The American Academy of Dermatology recommends detangling thick, curly hair gently while wet, ideally with conditioner still in it. Then rinse, blot and dry using gentle heat if needed. [3]
Is air-drying always better than blow-drying?
Dermatologists recommend partial air-drying as a way to cut down on dryer use. In a laboratory study of hair tresses, hotter, closer drying produced more surface damage. Air-dried samples showed a different type of structural change under the study conditions. The results support keeping a dryer farther away and moving when you use it. The study tested detached hair and compared specific drying settings, so the findings are best used as a guide to technique. [1] [2]
When to apply heat protectant
Apply it before styling, following the label for amount, placement and whether the formula goes on damp or dry hair. Check for explicit heat-protection directions when choosing a serum, oil or spray. Products sold for shine alone can have different instructions. Keep the heat low even when you use a protectant. [3]
If you’re comparing leave-in options, the brand gives pre-styling directions for both of these products:
- Kérastase Première Sérum Filler Fondamental, 90 ml is a leave-in serum the brand directs you to apply to towel-dried hair before blow-drying. [4]
- Kérastase Elixir Ultime L’Huile Originale, 75 ml is a hair oil the brand lists for use before heat styling. Check your bottle for application directions. [5]
One suitable formula is enough for this step. For more on how oils and serums fit into a routine, read our UAE guide to hair oils and serums.
Frequently asked questions
Can I straighten damp hair if I’ve used heat protectant?
Wait until your hair is fully dry before using a conventional flat iron. Apply protectant according to the label and use low or medium heat. [1]
How often can I blow-dry my hair?
Start by cutting back where it fits your routine. The American Academy of Dermatology advises blow-drying less often to limit damage. Try a lower setting on days you need the dryer and let your hair dry naturally when you have more time. [1] [3]
What if I’m seeing thinning as well as broken strands?
If breakage continues after you switch to gentler styling, or you notice thinning or patches of hair loss, speak with a dermatologist. The cause may need an assessment. [6]
