This is an issue that has been researched in recent years and it appears that more research is needed on more patients to reach a definite conclusion.
According to The National Cancer Institute, even though results are limited and inconsistent, “Over the years, some epidemiologic (population) studies have found an increased risk of bladder cancer in hairdressers and barbers. A 2008 report of the Working Group of the International Agency for Research on Cancer (IARC) concluded that some of the chemicals these workers are exposed to occupationally are ‘probably carcinogenic to humans’." The National Cancer Institute also reports on the conflict between long-term permanent hair dye usage and increased risks of certain cancers of the blood and bone marrow, such as non-Hodgkin lymphoma (NHL) and leukemia; also breast and bladder cancer.

In 2004, WebMD printed an article entitled, Hair Dye Linked to Blood Cancer”., Daniel J. NeNoon reported that results from a research study by Yale scientist, Tongzhang Zheng, “Long-term use of permanent hair dye—in dark colors—doubles a person’s risk of certain blood cancers... The results: An increased risk of non-Hodgkin's lymphoma was observed for women who reported the use of hair coloring products before 1980. Women who used dark-colored permanent hair-coloring products for more than 25 years doubled their risk of non-Hodgkin's lymphoma. The risk was nearly the same for women who used more than 200 applications of these products. No increased risk was seen in women who used semi-permanent dyes or temporary rinses.
So should women stop using permanent hair dyes?
‘Hair coloring is a personal decision for all kinds of reasons,’ Zheng tells WebMD. ‘But if I am the person, if semi-permanent or temporary dyes could serve my issue, I would do it. Because these contain much less of the ingredients linked to cancer.’" (end of quote). Read the entire article by clicking the link above.♦
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++A few months ago I was diagnosed with Lymphoma at Mayo Clinic with follow up 3 mos. visits to a Hematologist, blood specialist there. I then began to think about changing some of my lifestyle habits and a NATURAL Hair Color was an easy one to change. I am not on chemo since my Dr. says my own immune system is trying to fight this cancer. Chemo kills the good & the bad, therefore I'm thankful I do still have my hair at this time. My friend introduced me to Lustrous Henna when I complemented her hair. I didn't even know she used any type of color on it, because it looked so natural. She ordered my first time with her order, to try it out. So I have twice now, due to shorter hair. So glad I heard about this henna from her! I am thankful for the Lustrous Henna's shorter process time compared to others that require an extremely longer process and it leaves my hair in much much better condition than when I did salon color. My single priority, due to my health issue, is that it's safe, plus it looks and feels so natural and healthy. I can't say enough good about it.
It was my pleasure to visit with Syed a few days ago about Lustrous Henna. His patience and very informative manner is so helpful and refreshing. He is an asset to Lustrous Henna products. He helped me a great deal with tips on how to tone the gray as it grows in from my root line.
I sincerely thank you Syed and Lustrous Henna for the difference you have made in my life.
I'll be ordering again soon.
