MONDAY, Nov. 7 (HealthDay News) — Chemical hair-straightening products may increase the risk of uterine cancer, a new study says.

“The study, which involved more than 25,000 women in Japan, showed that the use of shampoos and conditioners that contain shikonin showed an increased risk of uterine cancer, the type of cancer most affected by the disease,” said Dr. Masaaki Horioka, of the Kurume University School of Medicine in Japan.

“This risk, however, can be reduced by using a cream conditioner containing keratin, a substance found in all hair roots.”

In the study, conducted from 1995 to 2007, the researchers found that women who applied conditioners containing keratin between ages 20 and 40 had a significantly increased risk of uterine cancer compared to women who applied conditioners containing keratin between ages 20 and 40 and older than 42.

The researchers also found that the risk of uterine cancer was increased among women that applied conditioners containing shikonin for less than five years, even if it was used only occasionally.

More than half of the women, who applied the conditioners containing shikonin, were diagnosed with uterine cancer during the study period.

They concluded that “conditions that require using a conditioner with the ingredient shikonin may be one of the major causes of uterine cancer.”

“The risk is especially high among women who have been diagnosed with ovarian cancer, as reported in previous studies,” Horioka said. “Therefore, it is very necessary to pay attention to the use of shampoos and conditioners that contain shikonin.”

He noted that women with uterine cancer are more likely to die from the condition than from other causes. In a 2011 study, uterine cancer accounted for more than half of all cancers that are leading causes of death in women worldwide.
