Hair colouring is an age-old practice that has become almost commonplace. Chemical molecules have largely replaced henna or indigo. But today you can choose an ammonia-free coloring that preserves your health and the environment.
What is ammonia?
L'ammonia, is the basic compound that opens the hair scales to allow the pigments to penetrate coloring.
The colorings "ammonia-free" products are not without health risks.
The latter use products that are not as strong as ammonia, but which still attack your hair.
The effects of ammonia on hair
Ammonia is mainly used for coloring hair, perming or straightening because it loosens the hair cuticles (microscopic scales that naturally protect the hair).
The scales therefore prevent any substance from penetrating the interior of the hair.
The scales of the hair must be loosened so that the active substances can enter the hair.
Once the cuticles have been detached, other substances present in the ammonia product such as pigments from coloring, chemical straightening agents, etc... penetrate the hair.
The substances can therefore act inside the hair as the ammonia has lifted the protective cuticles.
The ammonia in the chemical coloring opens the hair scales to let the color in.
Ammonia is extremely damaging to the hair as it temporarily breaks down the hair's natural protection.
The cuticles then close again, but not as well.
By doing colorings they no longer fit properly.
The hair becomes damaged and porous and permeable because the natural protection no longer covers it.
It becomes dull and rough and tangles quickly as the cuticles remain open.
Why is ammonia harmful?
Removing the cuticles from the hair is a very aggressive actfor the hair.
As time goes by, the cuticles do not move back into place effectively and this makes the hair permeable and porous, so it is no longer properly protected.
Because the cuticles are open, the hair no longer reflects light properly and the hair becomes dull and loses its shine.
When the cuticles are tightly packed around the hair, it is as if the hair is surrounded by a reflective mirror .
Ammonia can be dangerous because it can cause possible allergies, skin irritations (scalp irritation among others) like eczema.
Irritation can even be respiratory as ammonia can burn delicate lung tissue.
Therefore, do not use "ammonia" products in an unventilated environment.
Without you noticing, ammonia gases are released from the product and can cause micro-injuries and possibly damage to your lungs .
