Keeping your hair sleek all day long can be a challenge, especially if you have naturally wavy hair. Keeping your hair straight starts right when you wash it by using smoothing shampoos and conditioners, and there are always numerous options for smoothing products. There are several other ways to help keep your hair looking straight, such as using a boar bristle brush, blow drying your hair on a low setting, and straightening your hair in small sections.

Shampooing and Conditioning Your Hair

  1. Look for shampoos and conditioners that have lots of vitamins and minerals in them, giving your hair refreshing nutrients that will help smooth it out. These are usually marketed as smoothing, sleek, or straightening products.
    • Look for ingredients such as wheat proteins, pro vitamin B5, or hedera helix extract.
    • Take the time to comb the conditioner into your hair while in the shower, using your fingers or a wide-toothed comb. This can get rid of tangles and encourage straightness.

    Rub a few drops of a straightening serum onto your hair while it’s still wet. Make sure you distribute it evenly throughout your hair, either with your fingers or with a brush. Once the serum is spread out, you’re ready to blow dry your hair. [1]

    Squeeze out a dollop of a light or straightening mousse at least the size of a ping pong ball and apply it to your hair. Pull your fingers through the strands of your hair to evenly distribute the mousse from your roots to the ends. Use a hair dryer and a brush to straighten your hair out.

    Anti-frizz hair products have silicone in them, which helps seal the moisture into your hair. If you have hair that tends to poof out or get frizzy, look for an anti-frizz spray or cream.
    • Most anti-frizz products you can apply to either damp or dry hair.

Drying Your Hair

  1. Watermark wikiHow to Make Your Hair Stay Straight All Day
    Pat and squeeze your hair dry with a soft towel rather than ruffling or intensely rubbing your hair dry to prevent frizz from occurring.
    • Avoid using terry cloth towels and instead look for t-shirt or microfiber towels.
  2. Watermark wikiHow to Make Your Hair Stay Straight All Day
    If you're using a blow dryer, move the head of the blow dryer from side to side instead of focused directly on your hair. This will cause less damage to your hair and help prevent frizzing. [2]
  3. A brush made of plastic bristles can cause your hair to split and break. A round brush with a mix of nylon and boar bristles is best for blow-drying straight hair. [3]
  4. Watermark wikiHow to Make Your Hair Stay Straight All Day
    The hotter and stronger the air flowing from the hairdryer, the more likely you are to have frizzy, fly-away hair after you are done drying. Be patient and use the least abrasive settings to achieve smooth hair.
  5. Watermark wikiHow to Make Your Hair Stay Straight All Day
    This encourages the hair to dry in a straight direction and prevents frizz. You can use a brush or comb to guide your hair as you dry it. [4]
    • To save time, use a round brush to help style as you dry. This should straighten your hair enough that you won't have to use a flat iron afterward.
  6. Watermark wikiHow to Make Your Hair Stay Straight All Day
    Make sure the air intensity is also on the lowest setting possible and guide your hair with a thick brush, combing on the inside of your hair with the bristles pointing toward the blow-dryer. [5]
  7. If your hair has excess moisture in it when you go outside, it’s going to start to frizz. Dry your hair completely before leaving the house to keep your hair nice and straight throughout the day.
  8. Ionic blow dryers have the ability to break down water molecules, allowing your hair to dry faster. It's also much healthier for your hair, creating a smooth and conditioned look. [6]

Using a Flat Iron

    This not only protects your hair from the heat, but also encourages your hair to adhere to the straightness of the flat iron.
  2. Flat irons with ceramic plates are much better for your hair, causing less damage while straightening more efficiently. Check to see if your flat iron has a ceramic plate, and if not, consider investing in one that does. [7]
  3. Watermark wikiHow to Make Your Hair Stay Straight All Day
    If you try to straighten a big clump of hair at once, it’s not going to work as well. Separate your hair into 1–2 inches (2.5–5.1 cm) strands when you go to use the flat iron and your hair will end up much straighter. [8]
    • If you try to straighten sections that are too large, the hair closest to the plates will straighten, but the pieces in the middle will not.
    • Use even smaller sections if you have thick or coarse hair. Go for chunks that are about 0.5–1 inch (1.3–2.5 cm) wide.
  4. Watermark wikiHow to Make Your Hair Stay Straight All Day
    Straightening your hair at night before bed will provide time for your hair to cool and adjust to being straight before it’s exposed to the outdoors (and possible humidity). You can touch up any frizzy spots the next morning.

Combating Humidity

PDF download Download Article
  1. Watermark wikiHow to Make Your Hair Stay Straight All Day
    Once you've straightened your hair, use a dime-sized drop of smoothing oil to keep the humidity and frizz at bay. Argan oil and coconut oil are commonly used and work well. Anti-frizz products such as serums or balms are also good options. [9]
    • Apply the oil to the ends of your hair to roughly half-way up each strand.
    • Avoid applying oil to your roots.
  2. Rain might ruin those perfectly straight locks, so having an umbrella handy when you leave the house is a good idea. Using an umbrella when it's humid and hot outside will help prevent frizz too.
    • Use an umbrella when it's humid outside to help keep out moisture. The shade the umbrella provides will also allow you to sweat less, creating less hair frizz.
  3. Wide tooth combs have longer, more spread apart teeth, meaning they're great at detangling and won't break your hair as easily. Keep a wide tooth comb in your purse or car for times when you need a quick hair fix that won't result in frizz. [10]
  4. Watermark wikiHow to Make Your Hair Stay Straight All Day
    Spray hairspray over your hair once it's been straightened and is completely dry. Run a brush through your hair to distribute the hairspray, locking down any fly-away hairs. [11]
    • Avoid medium or strong-hold hairsprays, which will stiffen and harden your straightened hair.
  5. Watermark wikiHow to Make Your Hair Stay Straight All Day
    If you're traveling to and from a destination out in the humidity, it's easiest to use a hair clip or pony tail holder to briefly tie up your hair to help keep out the moisture. You can undo your hair again once you get to your destination, and it will have stayed much straighter.
  6. Covering your straight hair with a shower cap of some sort will prevent moisture from creeping in, meaning you'll have less frizz.
    Audrey Davis-Sivasothy, Chemist and Cosmetologist

    Start by clarifying hair and using a deep conditioning mask to increase moisture. Then, blow dry hair with a round brush to create tension and smooth the cuticle. When flat ironing, use small sections and multiple passes from root to tip at a high heat. Finish by sealing the cuticle with a cool shot of air. Regular moisturizing and wrapping hair at night will help prolong straight styles.

      • Hair masks make your hair healthier and silkier. Before showering, do a hair mask, like avocado, egg, or coconut oil. After showering apply a small amount of coconut oil to your scalp to help your roots remain strong.
      • I put a dime size of gel from roots to tips before straightening. It can make your hair sleek and helps you avoid burning and breakage when you’re styling.
      • Wrap all your hair around your head tightly and secure with bobby pins. This is best to do over night, so it can be nice and straight in the morning.

      If you want your hair to stay straight all day, use shampoos and conditioners with lots of vitamins and minerals, which are often labeled as smoothing, sleek, or straightening products. You may also want to try rubbing in a few drops of a straightening serum into your hair while it's still wet. Then, apply mousse, followed by an anti-frizz product before blow-drying your hair on the lowest setting. When you dry your hair, move the head of the blow dryer from side to side to reduce damage and prevent frizziness. Finally, use a brush with boar bristles to style your hair, since a brush with plastic bristles could cause your hair to break.
