Does diffuser work on straight hair?

I have pretty much straight hair and if i use a diffuser to dry it will it give it curls and waves or is that just to define people's curls with already curly hair.

Please be clear with your answers. Also do you reccomend any cream or spray to use before straightning/diffusing or blow drying your hair?

A diffuser will not work on straight hair. As you stated, it only works to define curls and texture that already exists within the hair.

If you would like to add body to your hair you could braid your hair in 5-10 thick braids (depending on the density of your hair, you don't want it to look crimpy) and let it dry like that over night. Make sure to apply a mousse first so your hair doesn't end up a frizzy mess in the morning. If you still have frizz issues you could apply some hair gel or pomaid, which would also help your hair to hold the style.

I hope this helps.
