The above chemicals often cause cross sensitivity to other chemicals. For instance, other chemicals, which have shown moderate sensitivity to a few people who have already been sensitized (cross sensitized) include azo dyes (found in temporary dyes, medications and foods), benzocaine (local dental anesthesia) Para-amino benzoic acid (common preservative to lotions, sunscreens and creams) etc.

If nothing happens, the dye might be safe for use. This should be done each time you want to use a new dye since as Dr. Rajani Katta, Dermatology Professor at BCM notes, “you can develop an allergy to a product at any point in time.” However, if you suffer from any unwellness or irritation, do not use the dye.

    Hi. I just want to note that there are alternatives. I go to a person I consider to be an expert in “all natural” herbal/henna hair color. (Not the “fry your hair with henna of the 70’s”–Liz Henao of in Durham NC is a former New York colorist who has studied herbs and can even do natural blonds….So…. grey is amazing but there are great alternatives.

  2. Just want to let you know I bought Herbatint which is listed here as non allergenic and I had a really bad allergic reaction. It wasn’t the color you list, it was dark blond, but nonetheless, maybe you should remove it from your article,

    I was never allergic to hair dye which I used for 20 years and suddenly I had a reaction with a product called Just for Men which I’ve used all my life. So I switched to herbatint with really bad results.

    Thank you,


    • Thank you for sharing your experience. Point noted

    • Juan I have the same experience as you ……. Used “just for men” for years on my beard and sideburns but now I can’t use it. The rash and itching is unbearable to live with. Creams do Relieve it a bit but not entirely. Have you found any other products? Thanks Alan
