Hair dyes don’t just color hair. The consequences of dyeing your hair
Actually, to enter the hair shaft and establish itself permanently, it passes through the cuticle, which is the hair’s natural protection.
To penetrate beyond the cuticle, hair dye uses ammonia which raises the pH of the hair, relaxes and lifts the cuticle. This entails as a consequence that the hair is damaged, since the cuticle should not be lifted in healthy hair.
Once the cuticle is lifted, the next step is to dye the hair to the desired color. So, the hair dye uses hydrogen peroxide to break down the natural pigment in the hair.
Peroxide is an oxidizing agent that dries out hair considerably, and is the reason colored hair can take on a “straw” texture.
It oxidizes the natural melanin pigments in the hair, removing some of the conjugated double bonds that lead to natural color, making them colorless.
When peroxide developer is absorbed, the cuticle remains lifted for the dye to penetrate. The more the cuticle is lifted, the more it weakens. Once the hair is rinsed, the cuticle goes back down, but the damage is done.
The damage can go beyond drying the hair
Almost everyone who colors their hair knows to be careful with freshly colored hair and to condition it thoroughly.
Hair dyes can definitely dry out your hair, but they can also make your hair much more brittle and break if use of these products becomes routine.
To prevent this from happening, you should condition regularly and use a conditioner that also regenerates hair like Redenhair Pro-Regenerative Conditioner. It is recommended that this conditioning be done before and after bleaching.

You should also reconsider your haircut. We all like to have a preferred hair color and maintain length, but you may need to be a bit flexible if your hair doesn’t respond well to the formula you’re using.
To maintain hair health it is necessary to get regular trims to prevent and eliminate split ends. It is much better to keep your hair as healthy as possible and cut it a little shorter, than to have hair that is overly processed, dry and with split ends.
Ingredients contained in dyes can be harmful to general health
Many of these products contain ingredients derived from coal tar such as aminophenols, diaminobenzenes, and phenylenediamines, which have been linked to cancer.
Coal tar is a byproduct of coal processing and is recognized by the National Toxicology Program and the International Agency for Research on Cancer as a human carcinogen.
The Environmental Working Group recommends limiting the use of dark and permanent hair dyes.
It’s important to note that researchers haven’t yet established an entirely clear link between dyes and cancer, although some studies in people who dye their hair regularly did show a correlation.
Because stylists and other professionals are exposed to the chemicals contained in hair dyes on a daily basis, European regulators have banned many of these ingredients in these types of products.
The FDA sanctions the use of coal tar in specialty products, including dandruff shampoos, but the long-term safety of these products has yet to be verified.
Also, it is worth noting that allergic reactions to dyes are rare, but not impossible. It is very helpful to do a patch test the first time you dye your hair or when you change colour. And, if you can, it’s even better to get tested before each application.
Signs of problems caused by dye
Every time you color your hair, you should be aware of the signs of problems that can appear after using the dye.
Any redness of the scalp, irritation, itching, peeling or blistering should be cause for concern.
If your symptoms are severe or last more than two days, it is highly recommended that you make an appointment with your dermatologist or primary care doctor.
Other less medically important problems can also occur when using these types of products. They often stain the skin on the scalp for a few days, which can be seen with the naked eye.
Products that bleach or lighten hair color remove the protective layer from hair fibers.
This makes the hair shaft thinner and weaker, making it much more susceptible to damage.
Using these lightening formulations too often can make hair look limp and lifeless and can even cause hair loss.
Precautions to take to avoid damage from dyes
When dyeing your hair with a hair dye, follow these tips for best results:
– Carry out a patch test, in this way you can rule out possible allergic reactions before applying the hair dye. This type of test can be done on the forearm.
– Always wear gloves when applying or mixing hair dye.
– Do not leave the dye in your hair for longer than the instructions suggest.
– Rinse the scalp well with water when you finish.
– Never mix different color formulations of hair dyes.
– Never try to dye your eyelashes or eyebrows with hair dye. This can permanently damage your eyes and could even cause blindness.
The safest bet is to closely follow all instructions that come with the dye and avoid formulations that contain PPDA if you are allergic.
Alternatives to hair dyes
If you want to avoid exposure to the chemicals contained in most hair dyes, consider trying a natural substitute like a plant-based henna dye or other all-natural hair color product.
If you use hair dyes to hide gray hair, you can consider other types of products such as Redenhair’s Anti-grey line. It is made up of a series of products that contribute to the formation of melanocytes in the hair bulbs, to stimulate the recovery of the natural color of the hair.
These products constitute a complete treatment to restore hair color and prevent the formation of new gray hair. Of course, if your hair is completely gray, we recommend that you try another alternative.
