Scientists who discovered the 'curly gene' are developing a treatment that could spell the end of hair straighteners.
It is hoped the breakthrough could lead to a pill to make hair straighter or curlier, rendering the must-have beauty accessory redundant.
The discovery will also make it possible to predict whether a baby will have straight or curly hair.
And it may even help police, with DNA found at the scene of the crime indicating how wavy a suspect's locks are.
Researchers in Australia identified the trichohyalin gene as being mainly responsible for creating curls.
Although it was known to play a role in the development of the hair follicle, Queensland Institute of Medical Research scientists have discovered its role in curliness.
Professor Nick Martin, author of the research, said a variation in the gene determined the straightness or curliness of hair. Professor Martin said it may be possible to come up with treatments to make hair straighter rather than relying on heated hair straighteners.
He said: "Potentially we can now develop new treatments to make hair curlier or straighter, rather than treating the hair directly.
"I will be discussing this with a major cosmetic company in Paris in January," he said. (NaturallyCurly guesses this is L'Oreal, who supposedly has been working on a pill for curly hair for some time.)
