Some Other Tips for Getting Straight Hair

Sure, shampoo is a great place to start when it comes to getting straight hair. But what else can you do? Here are a few tips that will help you get perfectly silky smooth locks. 


We can’t emphasize this enough but keeping your hair healthy is the most important thing to do if you want silky straight hair. Therefore, conditioning is crucial every time you shampoo. It smooths the cuticles and prevents breakage. 

On top of that, it detangles the hair, adds shine, makes them silky and less fuzzy. Above all that, it nourishes your hair with essential nutrients. 

Use Blow Dryer Cautiously

The heat from styling instruments can mess up your hair really bad. Studies have shown that dryers can damage the hair shafts. When you’re using a blow dryer, use the instrument with the lowest possible setting. You can blow dry with cold air. 

Make sure to move the blow-dryer continuously from roots to tips. And you would want to maintain a distance of about 5 to 6 inches when drying. You can use straightening creams or serums during the process.

Hair Masks

Hair masks are a great way to condition and nourish your hair. Luckily, you can create your own masks using simple ingredients such as raw eggs, marula oil, avocados, etc. A mask will relax your strands completely and make your hair straighter in appearance. 

As an added bonus, it will make your hair stronger and more beautiful.

Use Flat Irons

If you’re still not satisfied with the results, using a flat iron will be your next resort. Your shampoo has laid all the groundwork and it shouldn’t take a lot of time for you to get the desired results using some straightening tool. 

Don’t overdo it, though. Too much heat can be damaging. Make sure you’ve mastered the art of using a flat iron. Because if you don’t know what you’re doing, you may end up making things worse. 


Hairstyling begins in the shower. You may not get the desired results if you don’t use the right shampoo. Lucky for you, the shampoos we have reviewed above will give you straight locks and help you achieve the perfect hairdo. 

Depending on your hair type, they might not be able to fully straighten them but they do prep your hair and create a solid foundation for flat irons to do their magic.
