How to Blow Dry Your Hair Without Getting Damaged

Last Updated: November 25, 2022

Though blow dryers make your hair look great, all that exposure to heat is actually quite damaging to your hair. Your hair can end up dried out, frizzy, or with split ends, which are never a good thing. If you're worried that you're going to fry your hair with your frequent blow drying, there are some steps you can take to minimize the heat damage.

Preparing to Blow Dry Your Hair

1
Buy a good quality hair dryer. If you can afford it, buy a high-end dryer from a beauty supply store — some of them are so sophisticated they have a dial that lets you control the actual temperature of the hair. Most people won't want to splurge like that, though, so just make sure you buy a dryer with cool, warm, and hot settings. Do not buy one of the low-end dryers that only has a single setting.^{[1]

- Make sure you also buy attachments to help you style your hair, including a nozzle to distribute the air flow evenly and a diffuser to spread it out over a large area of hair.
- If you don't know where to find a beauty supply store, ask your stylist when you get your next hair cut.
2
Adjust the dryer temperature for the texture of your hair. Generally speaking, finer hair will overheat and burn more quickly, so you want to dry fine hair at a lower temperature. Thicker or curly hair might require a higher heat setting to get the job done, but don't over-expose any hair to heat.

- A trip down the haircare aisle at your local grocery store will give you more heat protections options that you know what to do with.
- These products come in a range of delivery methods, from creams to sprays — try out a few different kinds of products to figure out what works best for you.
- While you don't want to break the bank, you also don't want to skimp on these products. They're available in a wide price range, from $5-6 to $50.
- Look for products that contain silicone, which is especially good at protecting hair.

Blow Drying Your Hair

1
Separate your hair into sections. You don't need to physically separate your hair, but at least mentally plan out how to plan to dry your hair. You might begin with the hair on the left side of your face and work around the back to the right, or you might begin with the bottom layer of your hair and work your way to the outer layer.^{[3]

2
Begin blow drying your hair at a low temperature. Make sure to work your way through the hair sections you mapped out in the previous step. Work through your hair until it's about 40% dry.
- Massage your hair at the roots to encourage it to take on volume.
- Flip your hair upside down by bending forward, and direct the air flow at the back of your head to more easily dry the bottom layer of your hair.
3
Attach the diffuser to your blow dryer. This will help spread the more intense heat over a larger area, in turn reducing the damage.^{[4]

Continue blowdrying your hair on medium or high heat. A good way to use a diffuser is to drop your hair into its fingers and letting the air blow up through to the roots.
- Continue this until your hair is about 90% dry.
5
Let your hair cool back down. Cooling your hair back to a normal temperature keeps it from getting frizzy, and also feels great on your skin after you just blasted yourself with hot air for a while.^{[5]

- Flip the heat setting on your dryer to cool, or use the frost-boost button if your model of dryer has one.
- Run the cool air through your hair until it is cool.
- Allow it to air dry the rest of the way.

Start by drying off the root area and separating the hair into manageable, 2-3 in (5.08-7.62 cm) sections. Then, follow the blowdryer down your hair with a vent or round brush.

The key is to keep the flow of air going down the hair shaft. This helps keep the hair shiny and the cuticle lying flat.
