Tools you can't live withou. You may use some great product first.
To create a straight look make sure you have a great flat iron. For best results blow hair dry first as straight as you can and as dry as possible before using the flat iron.
To make hair curly have a great curling iron. Size is important as size decides how your curl looks. Half an inch to 1and a half inches in diameter to create curl every thing bigger than that will just make your hair wavy. Be sure to dry hair first naturally or with a blowdryer and diffuser.
A blow dryer is essential not just to dry your hair but also to reduce frizz if your hair is a bit frizzy.
A diffuser is a great attachment you will need if your hair is curly and you want to wear it naturally.
A nozzle at the end of your blowdryer is a great tool if you want to direct the air with more concentration and force. This is needed if you want to blow the hair straight from wavy or curly as the pressure of the air and the heat will make the hair straighter.
Electric rollers are a must for a great sophisticated look that is actually easy to execute. Dry the hair first till just a bit damp, than roll the hole head taking sections no bigger that the with of the roller and about one to one and a half inch thick. The smaller the roller the smaller the curl and if the roller is too big what you will get is a wave instead pf a curl.
If your hair is curly and you like to wear it curly make sure you have a spray bottle of water and use it when your trying to make the curls more defined. If you don’t wash your hair in the morning make sure to spray the hair every morning to activate the curl.
