  1. Straightening your hair works best on freshly washed or day-old hair. When washing your hair, tailor your shampoo and conditioning products to your hair type. For thick, frizzy hair, use a smoothing shampoo and conditioner. For thin, flat hair, use volumizing products. [1] Once hair is washed, dry it gently with a microfiber towel, spray it with a heat-protectant product, and then blow-dry it with a hairdryer. This will help to pre-straighten your hair, so you will have less work to do with the straightening iron.
    • Dry the roots of your hair with the hairdryer first, then work through the lengths of your hair.
    • Turn your head upside down while drying your hair to add more volume. [2]
    • Use a paddle brush to work through tangles and hold hair taut as you dry.
  2. Investing in a good heat protection spray which you apply every time you straighten is one of the best things you can do for your hair, without forgoing straightening altogether. The heat protection spray locks in moisture and prevents hair from becoming dry and frazzled. Apply the heat protection spray evenly over dry hair, holding the can about six inches away from your head. [3]
    • Don't apply the heat protection spray to your roots, as this can cause them to look greasy.
    • Heat protection sprays can be found at most drug stores and hair salons. It may be worth investing in a brand name product which will do a better job of protecting your hair. Try asking your hair stylist for recommendations.

    Dividing your hair into sections will ensure that you straighten your hair properly, without missing any strands. The easiest way to section your hair is to divide it into three layers.
    • Create the first layer by taking the front sections of your hair and scooping them back with your thumbs to grab all of the hair on the crown of your head. Separate this layer by twisting it and securing it with a hair tie or butterfly clip. [4]
    • Create the second layer by scooping up the hair that remains above your ears and securing with a hair tie or clip.
    • The third layer consists of any hair which remains unclipped, which should be the hair at the back of your head, growing around the nape of your neck.
    • If you have very thick hair, you can divide your hair into extra layers. If you have very thin or fine hair, you may not need to divide hair at all, or you can just split it into two sections.
  4. Most good quality hair straighteners give you the option to adjust the temperature of the irons. Using the right temperature for your hair will ensure you get the best results and will prevent you from doing unnecessary damage to your hair. The temperature your straightener should be set to will depend on your hair type: [5]
    • Fine or damaged hair should use a temperature of between 200 and 300 °F (93-149 °C).
    • Hair of average thickness which is in pretty good condition should use a temperature of between 300 and 350 °F (149-177 °C).
    • Very thick or coarse, frizzy hair should use a temperature of 350 to 400 °F (177-205°C).
  5. Watermark wikiHow to Straighten Your Hair
    Straightening your hair with a straightening irons does not involve anything very complicated, but there are a number of helpful tips you can follow in order to achieve the best results:
    • Use the right size strands. For best results, straighten your hair in strands that are 1 to 2 inches (2.5 to 5.1 cm) wide and no more than half an inch thick. If you use sections that are much bigger, your hair won't straighten properly, but if you use smaller sections, it will take too long.
    • Hold the hair taut. Use one hand to hold the section of hair taut as you clamp the straightening iron around it and smooth it through the hair. If it's not completely straight the first time, don't worry, just pull the straightener through again, but don’t do it more than 3 times on the same section.
    • Begin straightening about an inch away from the roots. This will leave a little volume in your hair and make sure it doesn't look too flat.
    • Use smooth rather than jerky movements. Try to run the straightening iron over the hair in one smooth, fluid movement. If you move it jerkily, you will end up with horizontal lines across your hair.
  6. Watermark wikiHow to Straighten Your Hair
    If this happens, it means that your hair is not fully dry. Stop, turn off the hair straightener and use a hairdryer to get your hair completely dry before you resume straightening. Using a straightening iron on damp hair is very damaging and will leave your hair in bad condition, so avoid whenever possible.
  7. Once you have straightened the bottom layer of hair, unclip the next section and begin to straighten it using the same technique as before. The top layer of hair should be the last section of hair you straighten.
  8. Watermark wikiHow to Straighten Your Hair
    It can be easy to overlook a strand or two throughout the straightening process. Don't forget to check the back. If you spot any waves or kinks, just go over them with the straightener one more time.
    • You can check the back of your hair by standing with your back to a mirror while you hold a second mirror in your hands. You should be able to see the reflection of the back of your head in the hand-held mirror.
  9. You can use a silicone-based serum to add shine, or spray your hair with hairspray to hold your hair in place. Just don't add any mousse or water-based product as this will dampen the hair and cause it to turn wavy.

Using a Hairdryer

  1. This may seem like a no-brainer, but you will need to wash your hair before blow drying. Use a smoothing shampoo and conditioner if your hair is thick or prone to frizz, or go for volumizing if your hair is thin or flat.
    • Only apply conditioner to the ends and mid-lengths of your hair. If you apply it to the roots, your hair will look flat and greasy.
    • Use a wide-toothed comb to work out any tangles while the conditioner is in your hair. The conditioner will make it much easier and will minimize hair breakage. [6]
  2. Once you step out of the shower, wrap your hair in an absorbent, microfiber towel and leave it for a minute or two. Then unwrap your hair and use your towel to gently dab or blot your hair to get rid of any excess moisture.
    • Don't rub your hair with the towel, as this will cause your hair to break.
    • Remember that you are not trying to dry your hair with the towel, it should still be pretty damp when you're finished towel drying.
  3. Watermark wikiHow to Straighten Your Hair
    Use a wide-tooth comb or paddle brush to part and comb your hair. Make sure to be gentle because damp hair is very fragile. Remember to work from the ends upwards, rather than from the roots down, as this will cause less breakage.
    • Defining your part while your hair is still wet will help it stay more naturally after it’s been dried and straightened.
    • If your hair is very knotted, try spraying it with a detangling mist or a leave-in conditioner.
  4. Watermark wikiHow to Straighten Your Hair
    Apply a small amount of straightening serum or cream to the ends and mid-lengths of your hair and massage it in. This will help to make your hair extra smooth and sleek after drying. [7]
    • If you can find a straightening product which contains a heat protection element, all the better.
    • Again, avoid applying these products to the roots, as they will weigh hair down.
  5. A good hairdryer is essential when you are trying to blow dry your hair straight. The more power and heat a hairdryer can provide, the easier and faster you can straighten your hair. If you need to invest in a new hairdryer, there are several things you should consider: [8]
    • Wattage. The wattage of a hairdryer is an indication of how powerful an air flow it has. The higher the wattage you can get, the better. Most salon hairdryers have a wattage of around 1800, though a wattage of 2000 may be necessary for very thick or curly hair.
    • Speed and Temperature Controls. Having a hairdryer with adjustable speeds and temperatures is a major bonus, as you will use different settings to achieve different styles. For example, a cool setting can be used to finish your hair with a blast of cold air, which helps to set the style while adding shine.
    • Weight. The last thing you want is a heavy hairdryer which is going to tire out your arm when you're just halfway through a blow dry. Look for a hairdryer which weighs less than two pounds. The weight should be indicated on the box.
    • Attachments. If you are using a hairdryer to blow dry your hair straight, you will definitely need a nozzle attachment which concentrates the airflow and prevents hair from frizzing. Check to see if a nozzle attachment is included with your hairdryer or if it needs to be purchased separately.
    Jen Atkin, Celebrity Hairstylist

    Preserve hair health while blowdrying. "My biggest trick is to use the ‘cool shot’ button. When you’re blow drying your hair, finish each section with a cool shot and a boar bristle brush with that cool air–it helps to get the cuticle to really stay calm and smooth."

  6. Watermark wikiHow to Straighten Your Hair
    Turn your hairdryer on (to a high speed and heat, if possible) and begin roughly drying your hair. Concentrate on drying your roots, using your fingers to lift and separate your hair. You shouldn't use a brush just yet. [9]
    • Make sure that the hairdryer is pointing downwards to help keep your hair smooth and frizz-free. It should be blowing hair down from the crown of your head, rather than upwards.
    • You should continue rough drying your hair until it is about 60% to 80% dry, but no more.
  7. Dividing your hair into sections before you finish blow drying is a good idea, as it will help you to focus on straightening one layer of hair at a time. Split your hair into three layers - one at the crown of your head, one at the middle sections and one at the nape of your neck. Use butterfly clips or hair ties to keep the top two layers out of the way for now. [10]
    • If you have bangs, leave them down and dry them first before you dry the bottom layer. This is because bangs will dry quickly and they will be harder to straighten once dry.
  8. The type of hairbrush you use while blow drying your hair will have an impact on how your hair turns out. If you want to add volume while you straighten, or add a slight curl or flick to the ends, use a thick round brush. But if you want poker-straight locks, a paddle-brush is your best option.
  9. Watermark wikiHow to Straighten Your Hair
    Take a section of hair between two and four inches wide and hold it taut with the hairbrush. Keeping the hair taut while drying is the most important technique in achieving straight hair.
    • You also need to make sure that you are directing the air flow downwards - the nozzle of the hairdryer should be pointing towards the ends of the hair as you dry. This keeps the hair cuticle down, giving you a smoother, sleeker result.
    • Once you have completely dried each section of hair, finish it off with a blast of cool air to help set the style and add shine.
  10. Once you have completely dried the bottom layer of hair, remove the butterfly clip holding the middle layer. Dry this layer of hair using the same technique as before. Once the second layer is completely dry, let down the third and final layer and finish off your blow dry.
    • Once your hair is completely dry, it should look straight and sleek. If it's still a little wavy, you may need to dry it further, really using the brush to pull the hair straight.
    • And if all else fails, use a straightening iron to go over any particularly stubborn bits.
  11. To set your style and give your hair a little extra shine and control, apply a pea-sized amount of finishing product to the ends and mid-lengths of your hair. A shine serum or a shine spray will both do the trick. If you're worried about your hair falling flat or losing its shape, mist it with a light layer of hairspray, holding the can about six inches away from your head. This will ensure that your hair stays straight all day (or night!) long.

Keeping Hair Straight

  1. The water content will cause your hair to curl back up or frizz immediately. Do use a hairspray if you live in a humid area, however. Your hair will be prone to frizz due to the added moisture in the air. [11]
  2. Rain will undo all your hard work and leave you with a frizzy mess. Also, remember to carry a headband with you in the summer to keep the perspiration from your bangs. If you are jogging or walking, consider putting your hair up in a ponytail.
  3. Even if you love the straight look, a curling iron can be used to flick out the ends of your hair or flick the front sections away from your face. [12]
  4. Don't worry though, all you have to do is repeat the straightening process again! Just don't straighten your hair too much, as it will cause your hair to become dry and damaged. Try to save the straight look for special occasions! [13]

    I'd suggest using hydrating shampoos and conditioners. Try pairing that with some oil, such as argan oil, to help nourish the hair even more. If you use heat to style your hair, add on a blow dry cream. Refrain from heat styling when you can, though, as heat and over styling can damage your hair. There are things that you can do in a salon as well. A keratin treatment, for example, can be a good option if you have super frizzy hair that you can't seem to manage or control.

    Using an egg in your hair will not straighten it. Eggs are used in hair masks to condition and strengthen the hair to prepare the hair for straightening (and other hair services) and keeping it healthy. However, an egg can not straighten your hair.

    No, you don’t have to wash your hair again as long as it is clean and free of hair products. If not, it would be best to have clean hair before straightening it.

      Tips

      • Make sure you don't add any oils to your hair before you straighten it, because it will fry your hair. Just imagine what happens to a french fry in oil.

      • NEVER EVER straighten, or curl your hair when it is wet. It damages your hair and you will start to see smoke. If you do take a shower before you straighten, be sure to blow dry it until it's dry.
        Thanks

      • When using a flat iron, consider using some heat protectant. It doesn't have to be very expensive. You can just pull off the cheap dollar store brand.

      About This Article

      Article Summary X

      To straighten your hair with a flat iron, first wait until it’s completely dry since straightening wet hair can damage it. Apply a thermal protectant to your hair to protect it from the heat even more. Then, plug in your flat iron and wait for it to heat up. Grab a ½-inch (1 ¼-cm) section of your hair, and run the flat iron from the roots to the end. Avoid straightening sections larger than this since you’ll need to go over them more with the flat iron, which can lead to more heat damage. After you straighten one section, continue straightening ½-inch (1 ¼-cm) sections of your hair until you’ve gone over all of it. For more tips from our Cosmetologist co-author, including how to straighten your hair without a flat iron, read on!
