What are the effects of dye on hair?

Dyeing hair is not a trivial matter, it not only changes the shade of your hair, but the chemical dye also attacks the hair, making it weaker, dryer and more damaged. The side effects that appear after repeated dyeing are explained below to help you better understand how and why this phenomenon sensitizes hair.

Understanding the effects of dye on hair also helps to better understand colored hair and its specific needs. This way it's easier to know how to look after your hair and what products are right for them.

What does hair look like after being dyed?

Healthy hair — hair fibers are perfectly intact

For healthy hair, the hydrolipid film is intact and used to effectively protect against daily external aggressions. The keratin scales are perfectly positioned, smooth and tight. The hair is strong, shiny and silky.

Colored hair — hair fibers are aggravated

In the chemical process, keratin scales are removed, allowing the oxidants and dye to penetrate the hair fiber. This action is essential to change the color of the hair for a long time. This can also damage the hair structure.

Why is the hair less beautiful after being dyed?

At first, thanks to color, hair gets a burst of youthfulness and radiance. But very quickly, the damage inside the hair fiber starts to appear on the surface.

After repeated dyeing, the side effects on hair are readily apparent and the problems extend deep down into the hair fibers.

Affected by chemical dyes, the hydro-lipid film that coats the hair and prevents the loss of moisture no longer plays its role as a protective barrier. Hair then becomes dry and coarse.

Removed as a result of the dye, the keratin scales no longer ensure the smooth, glossy appearance of hair: it's left dull and is extremely difficult to style.

Deeply aggravated, the internal structure of the hair becomes weaker. The colored hair loses its structure: this is when the hair becomes brittle and split ends are likely to appear, which can make it look uncared for and frizzy.

Can hair be dried out by dyeing hair?

Chemical hair coloring has an annoying tendency to attack anything that protects the hair, preventing it from penetrating the hair so that it can carry out its mission.

The first barrier to its path, the protective hydrolipidic film, which is rich in sebum and therefor prevents the hair from becoming dry.

Once damaged by the dye, this hydrolipidic film continues to be attacked daily: shampoos with overly high levels of detergent, brushing or blow-dries that are too hot, too aggressive or too frequent, walks in the sun or in the wind, straightening, curling...

As long as the hydrolipidic film is absent, the hair is left with no nourishment nor protection.

The hair is no longer just dry, but it is also damaged, coarse and difficult to style.

Is it possible to repair damaged hair by dyeing it?

Even when you know that dye damages your hair, there is sometimes no other option. Dyeing your hair is an effective way to change your appearance, giving your style and face a different look. Giving up your chosen color to go back to your natural color is not always easy.

What if the solution to keeping your hair healthy was to repair the damage caused by the dye?

To restore the hair's natural beauty, it’s possible to use natural extracts, such as René Furterer's natural Okara extract with its multi-repairing properties.

All its effectiveness lies in the richness of its natural composition:

  • restructuring proteins, including amino acids similar to those of keratin in the hair. These proteins will protect hair from aggressions such as pollution, UV rays, heat, etc. 
  • protective lipids that will complement the lipids naturally present in the hair, giving it a certain elasticity and impermeability
  • nourishing sugars that are necessary for restructuring the damaged fibers due to the effect of the dye. 

Thanks to right care, not only is the damage made to colored hair reversed, but, as the hair regains its beauty and shine, the color is even more beautiful!

Colored hair: are silicone-free hair products better for your hair? What are their effects?

Conventional cosmetics have made silicones successful: any hair they touch is soft and irresistible. But at what cost?

Silicone coats the hair on the surface but does not care for it deep down: inert substance, silicone is an element derived from petrochemistry and does not provide any benefits for hair fiber. On the contrary, its coating and occlusive side forms an insulated layer that deprives the hair of the effectiveness of the active ingredients. Silicones can therefore to reduce the effects of hair dye by caring for your hair, but it’s not!

Silicone only acts on the surface of the hair, but does not care for it. And it’s a polluting component.
