Scientists at cosmetic company L’Oreal claim to have invented the first product which can acually "reawaken" dormant hair cells and allow them to grow back.
It could offer hope to millions affected by male pattern baldness or just the thinning of hair through old age or for medical reasons.
Already demand for the new treatment has seen salons taking thousands of pre-orders even though the recomended three month treatement costs nearly £300.
After 90 days researchers claim that the liquid "Kérastase Densifique", when applied to the roots, can promote the growth of more than 1500 new hairs.
Patricia Pineau, the head of scientific affairs at L’Oréal, added: “We’ve known for 100 years that hair grows and falls out.
“We haven’t known what makes hair regenerate until now. It is all about hair stem cell environment. We have been able to develop a cosmetic product that respects the natural way hair regenerates.”
Scientists said the product, called Densifique, regenerated roots by targeting areas of the scalp prone to hair loss rather than actual fibres.
Experts say there are a variety of factors which can cause hair loss ranging from stress levels and a person’s diet, through to hormones and pregnancy.
Award winning hairdresser Luke Hersheson said: “Many women are really worried about the loss of their hair, the loss of volume, and the fact that they don’t have as luscious locks as they did when they were in their early twenties.
“Stress, diet, hormones and pregnancy are all factors that can affect the health of the hair and scalp.
“This new treatment is set to help alleviate this problem. It has an instant densifying action on the hair fiber, boosting the number of hairs on our head and the quality of these new hairs directly at scalp level. It’s set to be the holy grail for a lot of women – and men.”
The average human has on average between 100,000 and 150,000 individual hairs and the manufactures claim the new product “assists” natural growth rather than “disrupt” it.
Scientists, based in laboratories of L’Oréall in Paris, developed a molecule using a formula called Stemoxydine, which after testing was found to have increased hair density by up to four per cent.
Cass Coulston, Kérastase general manager, last night described it as an astonishing “technological breakthrough”, which led to improved hair density.
She added: “Hair thinning is not just associated with ageing, it can happen as a result of a poor diet, hormones, stress, post pregnancy and over processing hair.”
Kérastase Densifique will be available in salons within the next fortnight.
