Hair colouring natural and unnaturalHair colouring is as old as the hills - an ancient practice but even then dangerous substances such as lead based concoctions were sometimes used (lead acetate is even now a common ingredient). If a natural product contains words like amino, nitro or phenyl or names of colors starting with the letters HC, the product is not natural. Problem ChemicalsAn oxidative haircolour is ANY haircolour that contains a tube (or bottle) of hair colour and a bottle of developer that are mixed together before application. An oxidative haircolour is either a permanent haircolour or a “long lasting semi-permanent haircolour” Contains P.P.D. or P.T.D. within the colour formula (both allergenic sensitisers). So a typical chemical based hair dye is a PPD-based dye in one bottle together with various other chemicals (e.g. resorcinol to vary the colour tone; ammonia which is necessary for the chemical reaction), and an oxygen-providing 'fixative' (usually hydrogen peroxide) in the second bottle. Hair color allergic reactions are related to PPD which is short for p-Phenylenediamine or Para-phenylenediamine. Para-Toluenediamine (P.T.D) is similar. Both ingredients are in up to 90% of hair dye products in Europe and are the primary cause of allergic reactions that can vary from an itchy scalp to scabs forming on the scalp,rash on the body, or in the most extreme cases a swelling of the face and neck where medical treatment is then recommended as a matter of urgency. Others argue that serious reactions in hair color can be linked to ingredients such as ammonia, peroxide or diaminobenzene. Non ammonia oxidative colours normally contain Mono Ethanolamine which has no smell as it does not evaporate in the colour process and is again a well known irritant. Being able to colour your hair or to get rid of grey hair in 10 minutes is very tempting when compared to the time it takes using "natural" methods but the long term affects on your hair and even your health might be too much to risk. Check out the ingredients in your hair dye: hair dye ingredients Hair dyes: natural to chemicalThere are dozens of brands, some of which are hard to find in shops. The natural products are the ones you are least likely to find in a shop or big store like Boots. They don't want to sell cheap and healthy solutions. You need to do a spot test first to test for allergies and a strand test to see if you like the colour. Natural henna based hair dyesHenna - Lawsonia inermis (or sometimes Cassia is used) seems to be the base for all "natural", chemical free products. Of course, Henna has a "chemistry" and you should do a spot test first to see if you are allergic. Natural really means plant based, unprocessed, pure and without man-made additives. Henna is grown and produced in many countries and the quality (measured in age and dye content) and colour results differ. there are lots of websites offering instructions and user experiences. Henna always produces shades of "red". More detail about Henna hair dye and its companion herbs Aubrey Mechanics - Color Me Natural.

Health and Beauty suppliersThe women's sites provide lots of information relevant to men although you have to remember that men's skin and hair is different and that's why there are men's products - it's not just marketing. On the other hand lots of products marketed at women are just as good for men. Cosmetics ingredients sciencePlease add to this list of common hair dye ingredients by registering first. Here are some sites that list typical ingredients and evaluate their safety level. And this site gives a more detailed look at hair colouring but in layman's terms. Hair colouring science is all about molecules - your own natural hair molecules and the colour changing ones in the dye chemicals and the reaction between them. The permanent dyes enter the hair and can't get out while the less permanent ones eventually leave the hair and so fade. The Universal Hair Colour Numbering SystemDepth (Base) 1.0 Black 2.0 Darkest Brown 3.0 Dark Brown 4.0 Medium Brown 5.0 Light Brown 6.0 Dark Blonde 7.0 Medium Blonde 8.0 Light Blonde 9.0 Very Light Blonde 10.0 Lightest Blonde/Pale Tones The six tones that can be added to any of these above colours to create every hair shade you may wish to achieve. 1. Blue 2. Green (referred to as Ash) 3. Violet 4. Red 5. Orange 6. Yellow When hair is darkened by a permanent colour, the base ingredient within the chosen shade will transform every hair to the same depth, so overall results will appear much darker than expected. For this reason, when deciding upon a preferable colour to use, always choose one shade lighter than you see your hair. Information from Herbatint
Hair TreatmentsFor coloured hair, it is important that you choose a shampoo that will not strip the colour from your hair, look for a low PH shampoo as this will not force the hair cuticle open and release the colour. |
