However, if you have straight hair, then you will need to work harder to achieve the messy curly hairstyles look. To make straight hair look messy, there are many ways. The easiest is use a sea salt spray in your hair, then make four equal sections in your hair.
Make four braids out of this section of your hair. Wait till the hair is dry, then unbraid your hair and you will have great beach waves in your hair, which you can use to create messy updos. Other ways to style straight hair messy include using rollers, curling iron, perming, etc.
You can apply cream on your hair and then fix rollers in them. Keep the rollers for the night and next day when you unroll the hair you will have great wavy locks. You can also use curling iron to make your hair wavy or curly. But, make sure you use enough hair serum and cream on your hair, before you use the iron.
The cream and serum will prevent any burning of the hair during ironing. To perm your hair you will need a stylist, but perming will make your hair permanent curly, and hence it is advisable that you stick to the other methods to make your hair wavy.
Another way to keep your hair straight and still make them look messy is to cut them into choppy layers; which can make great updos without opting for curly updos. To cut your hair choppy, hold a hair strand at a 45 degree angle, tilt your scissor and make the cut. This way work on all your hair strands but at different lengths.
Another way to create a messy updo without styling straight hair to wavy is to side part your front hair, then middle part your back hair. Form pigtails on both sides, roll them up and fix them into two buns. Some hair will come out of the pigtails, that will give a cool casual look. Leave some side bangs open.
