What Can Cause Cancer?
Before dyeing our hair, we should keep in mind the following: ‘The Environmental Working Group’ research results showed that almost seventy percent of hair-dye products may cause cancer.
According to the 1994 'National Cancer Institute' report, dark dyes that were used by consumers for a long time can enhance the risk of certain cancers such as multiple myelomas and non-Hodgkin's lymphoma.
Also, 2001 ‘International Journal of Cancer’ study established that those persons who use chemical permanent hair dye are likely to develop bladder cancer.It is a serious warning!
There are quite a few dangerous ingredients. If you use chemical dyes, make sure that these dyes do not contain the following ingredients:
- ammonia
- peroxide
- PPDs (para-phenylenediamines - create color and are carcinogenic)
- coal tar (great cancer risk)
- lead
- toluene
- resorcinol.
