Hair Colouring Quite Hairy
Written by certifiedorganicColouring your hair? Are hair dyes safe? Not sure you want the answer?! Here’s what you need to consider to reduce your toxic exposure to chemicals in hair colourants:
• Dyes may come in direct contact with the scalp, which is very porous and absorbs substances easily and quickly.
• Chemicals may provoke an immediate reaction like burning and itching or may build up in your body and add to your chemical body burden over time.
• Serious health problems linked to hair dyes: non-Hodgkin’s lymphoma, bladder and ovarian cancer, leukemia & multiple myeloma, and rheumatoid arthritis.
• Others include hair loss, allergies, eye injuries, skin and scalp disorders like eczema and rosacea.
The experts disagree about the impact of chemicals in hair dyes - some studies raise questions about safety and risk of cancer while others do not find “strong evidence” or a “marked increase” in definitive risks. Concerns about hair dye related chemicals are mainly centered around:
• The combination of ammonia and peroxide (burns skin and eyes).
• Common petrochemical p-phenylenediamine (PPD), and its derivatives, 4-MMPD and 4-MMPD Sulphate.
• Coal tar dyes (FD&C, D&C synthetic colours), lead acetate and resorcinol
• The chemicals in hair dyes also damage, stress and dry out your hair.
Over 480 out of 657 hair colorants ranked at the Skin Deep cosmetics database are considered high hazard. So know what colouring processes you are currently having applied.
If you have always coloured your hair, the thought of simply going natural one day is unthinkable - here’s info to help make your choice less toxic…
The more permanent the colour, the more toxic - reduce exposure by:
• Highlight/lowlight sections of hair rather than the whole head
• Try techniques where chemicals do not touch scalp, such as a cap or paint
• Patch test to determine if allergies to the product are present
• Darker colours have been shown to be more toxic and increased risk of cancer than blonde and red shades.
• Hennas, herbal/mineral/vegetable dyes and food based ingredients are the least toxic of all and can leave your hair luscious, healthy and full of shine.
• What about natural hair dyes? While natural hair-dye product claims exist, few if any of them purport to be chemical-free. Many supposedly ‘natural’ products contain ammonia, peroxide or PPDs or other suspect chemicals.
• Ask you colourist to use natural products or seek out a chemical free, odor free or a herbal hair salon. Tell us if you find one - they are hard to come by! (Click on the comment link!)
