Hair coloring more than six times a year increases the likelihood of developing breast cancer. This was stated by the physician of the London hospital Princess Grace Hospital professor Kephan Mokbel, reports The Times.
The doctor studied the medical history of patients suffering from breast cancer, and concluded that in women with colored hair this diagnosis is set at 14% more often.
Mokbel recommends reducing the effect on hair of synthetic dyes up to six times a year and regularly undergo examination by specialists.
According to him, it is preferable to choose means that contain a minimum concentration of aromatic amines. At the same time, dyes, which consist of natural plant ingredients, such as rose hips or rhubarb, are hardly dangerous to health.
