  2. Permanent Hair Coloring Elements: • Ethanolamine • Sodium carbonate • Ammonia Facts: • Permanent is known to be “irreversible.” • The process requires two separate formulations to be mixed together just before application to the hair. • The process usually takes 20 to 40 minutes, while chemical reactions take place.

  3. What is Ethanolamine • Ethanolamine, also called 2-aminoethanol or monoethanolamine, is an organic chemical compound that is both a primary amine and a primary alcohol. Like other amines, monoethanolamine acts as a weak base.

  4. Sodium Carbonate Sodium carbonate, Na2CO3 is a sodium salt of carbonic acid. It most commonly occurs as a crystalline heptahydrate, which readily effloresces to form a white powder, the monohydrate.

  5. Ammonia • Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. It is a colorless gas with a characteristic pungent smell.

  6. How do these elements come into play?

  7. Ethanolamine • Is an organic compound that is naturally found in coconut oil. • It is by far the safest alkaline agent available in hair coloring today. • It has a tendency to gently swell the hair cuticle open rather than causing any corrosion associated with ammonia • A lot of permanent hair coloring lines use this as their primary alkaline agent for advanced professionalism.

  8. Sodium Carbonate • it is most commonly known as “soda ash” or “washing soda” • It opens the cuticle of the hair slightly • It is sufficiently needed to lift the cuticle of the hair. • It should be considered when selecting a healthier and better performing alternate to ammonia based hair color.

  9. Ammonia • It is used to lift the cuticle of the hair allowing the pigments to penetrate into the hair shaft • It also oxidizes to create a permanent color effect. • It is a caustic corrosive that irreversibly damages the cuticle during the hair color process • It corrodes both the sebaceous glands and hair follicles in the scalp, leading to brittle and thinning hair.
