Do not wash your hair the day or two before you plan to curl. [1] X Research source
Let your hair air dry rather than using a towel. Using a towel will make your hair difficult to put into rollers. Only use water when washing your hair before a curling.
Continue combing until the comb does not catch any knots.
Let the spray sit in your damp, combed hair for around 3-5 minutes before putting in the rollers.
Continue putting in the rollers until all of your hair is rolled up.
Do not use much more than three sprays since too much hairspray can be damaging to your hair and the environment.
Apply even more hairspray to ensure that your curls last for a long time.
You may also wish to apply a heat-protective spray to your hair before using the iron since it can be dangerous the first few times. These sprays can be found at any beauty store.
Do not use a cheap iron. Invest in a more expensive, reliable iron which will provide consistent heat.
Be sure to avoid letting the iron sit in one place too long. Do not let the iron touch your skin since it is very hot.
This will help hold the curl in and should increase the time the curls stay in your hair.
Hairspray is key to holding hair in place and will help curls stay for a long time. Let the hairspray sit in your hair for around 10-15 minutes.
You can also then braid this hair before bed if you want to try an alternative method.
