Do Hair Dyes Cause Cancer?

Is the higher rate of bladder cancer among hairdressers due to exposure to hair dyes? And what about at-home use of hair colorants?

Why does our hair turn gray in the first place? What can we do about it? I discuss everything in the Preserving Your Hair chapter in my new book How Not to Age (https://nutritionfacts.org/book/how-not-to-age/). (All proceeds I receive from book sales go directly to charity.)

56 Risposte a “Do Hair Dyes Cause Cancer?”

  1. I finally gave up the battle and stopped coloring my hair. I had a severe reaction to an over-the-counter hair dye for which my doctor put me on steroids to suppress the reaction. What a mess. Anyway, my hair sure feels a lot healthier and thicker now. ✌️

  2. Better to steer clear of chemical based products full of SLS, ammonia, PPD, parabens, lead, artificial fragrances, resorcinol and titanium dioxide.

  3. That's why I use henna and indigo and made my mom to transition to henndigo too. Hate the process as it's extremely tedious but love the results. Won't use hair dye until they come up with something safer

  4. I was never a fan of needless additives/enhancements of any kind like hair dyes, makeup, dyes or perfumes, artificial colors or flavors. I'm a chemist so I'm naturally suspicious. Wade through a stack of Safety Data Sheets and you start wondering if it's worth the risk. Over the years plenty of products have contained ingredients that have been just fine-until they weren't. Not everything is a cancer risk, to be sure, but sometimes it takes years before the danger becomes apparent and even longer before a change is made. I'm not eager to be part of that data set.
    I'll be a grey-haired, unscented plain Jane getting my single-ingredient food from the garden and produce/grain/legume aisles.

  5. Everything causes cancer these days. I eat a wholefoods diet, use natural products and live as healthy as possible. A bit of hair dye is unlikely to be the thing that kills me, a few times a year. Live your life as best as you can, not walking on glass over every pleasure.

  6. LOVE Dr. Greger’s work, & I’ve always appreciated the generally apolitical info, but gray hair may “limit women’s subjection to a sexualized gaze”?

  7. I color only 2-3X a year. A Natural blonde now in my 60s, I use hair dye without ammonia or peroxide to stay blonde. I never, ever clean off the dye down my body such as a showering does. I wash it off over my head in the sink. Intuitively, I don’t want it going down my body – absorbing into my skin throughout my body (showering.)
    My advice is to dye your hair with the best product possible; reading and researching ingredients. They do have organic hair dyes. Every little bit helps. Also, choose a hair dye as close to what your hair color would be naturally (dark gray = black) white = platinum blonde) etc.

  8. I never colored my hair and went gray in my early 40s – I was swimming against the tide as I was the only one in my local age group to do so. I’m often asked if I’m my kid’s grandmother instead of their mother.

  9. English und Deutsch
    I have only ever dyed with vegetable dye, this was in a tube and was easy to apply, no chemicals and has dyed my 90% grey hair, but you had to pre-dye with red, so that in the second pass with brown, so that the color is also dark, you have to let both work for at least 4 to 5 hours, with thick hair possibly even longer. Just try out how long it takes for the hair to be colored enough. As I no longer feel like it, I no longer dye my hair.
    Ich habe immer nur mit Pflanzenfarbe gefärbt, diese war im einer Tube und ging gut aufzutragen, keine Chemie und hat meine 90 % grauen Haare gefärbt, allerdings musste man mit rot vorfärben, damit im zweiten Durchgang mit braun, damit die Farbe auch dunkel wird , muss man beide mindestens 4 bis 5 Stunden einwirken lassen, bei sehe dickem Haar evtl. noch länger. Einfach ausprobieren, wie lange es dauert bis die Haare kräftig genug gefärbt sind. Da ich jetzt keine Lust mehr habe, färbe ich nicht mehr.

  10. Thanks a lot. Due to exorbitant hair cutting price, and also the risk of financial scam by the hair cutting houses in my country, which ask you to charge for a year of service but close their business within less than a year, I stopped going to the hair cutter altogether. I do my own hair cutting, even though I was laughed at by others. It seems that avoiding going to the hair cutting house forever is a very wise decision. I am glad that I also avoid so many carcinogenic manmade hair chemicals. God bless!

  11. i had a terrible reaction to overtone which is marketed as being safer. after that i switched to henna but it’s such a pain that i gave up on that too. cute hats, i guess?

  12. Hairdressers are exposed to much more than hair dye.
    Hair sprays, hair additives, a lot of perfumes, shampoos, and as you said, often have very poor ventilation.
    I now use the most non chemical type, only available at health food stores or online, (that does not have that chemical that was highlighted ) and seem to not have negative reactions, but am very strict about all natural make up and no purfumes. I do miss hairsprays etc, as I have fine hair and it is quite a practical assistance.

  13. hair dye use is a mental issue first, and a society problem. normal humans do not want to die anything, they have to live in a society that is broken.
    so when we know we live in a broken society or civilization making us all mentally broken, what are we going to do about it!

  14. Ivermectin causes cancer the cell to pop open and die.
    Fenbendazole same… get some food grade Diatomaceous Earth take a tablespoon of that and 8 oz of water in the morning take;binder and some fulvic acid intake.

  15. This is just hair dyes. What about the dyes used in dishes, etc. I understand blue dyes on dishware is higher in chemical contamination. Never dyed my hair, never used cosmetics very long. Our skin is a major organ, what are we doing to that with cosmetics..

  16. If there were a direct cancer link or causation or even near correlation, there would be lengthy court cases and settlements.
    There is a personal belief on how to live one’s life and then there is scientific facts that supports some claims. If you wonder if hair dyes causes cancer, the short answer is the ones sold in the US do not have the carcinogenic chemicals such as ammonia in hair dye and formaldehyde in hair straightening products. If you buy these hair products, say in Japan, they do contain ammonia. So . Chemrisk which the first research paper was presented from is a for profit group whose whole purpose is litigation (Wikipedia).

  17. I don't dye my hair anymore but I worry about when it will start getting gray because even if I will likely keep it gray once I'm much older, I don't wanna have gray hair in my 40s or 50s. So I don't know what to do then because I heard henna dyes can contain heavy metals?

  18. I got a perm in 6th grade in 1988 and it never went back to normal straight. I think it must have damaged my dna permanently. I also read the same thing happened to actor Matthew Mcconaughy.
