Semi permanent hair colour. or ?

11 May

Welcome to BACK2MYROOTS B2MR: Regular postings of fresh new topic’s

A place to share thoughts post comments and idea’s on matters relating to hair colouring skill and techniques and anything industry related.

Semi Permanent Hair Colour:

Mousse, gels. Demi, permanent,

When we think about semi permanent colour we naturally assume slow wash out or fade maybe 6 to 8 washes up to 6 weeks.

In reality we have to consider so many things be it in the salon or at home? What we expect from this colour .What is my hair condition is it advisable?

Are we going tone on tone? Are we  considering putting a darker shade than our natural level not a great deal is achieved putting lighter over darker!

If putting a cool Red {blue red} over say Blonde as it fades a pinkish, purple, hue could be left. bright true Red could fade leaving {red orange} hue.

The porosity of your own hair plays a part in how these colours may deposit. How long they last and how they fade. As well as the chemical make up of the product.

Buyer beware!

A product that is promoted as semi permanent can still have ingredients in the formulation to open the cuticle and help with the deposit of the said colour.

In some cases they can leave behind trace chemical residue the same can be so of the mousse colour refreshing products Reds. Blondes.  They can leave behind trace elements that build up and can effect professional colour applications.

In some cases they can effect the deposit of professional colour creating banding issues or poor deposit. see article on shampoo with colour pigments added.

So as stylists as always consultation is key:

How many of you have cried their eyes out! after a colour has gone wrong? Been close to shaving your head after unfortunate choice of hair colour? Hands up! Yes ? With hair the colour of scrambled eggs…Dying your hair is not as easy as the adverts make it out to be.  I am not talking about the technique! Just the many things to take into account when considering hair colour both product and desired effect! 

It’s product choice.  It’s hair condition. It’s history of the hair previous colour. It’s application. It’s formulation. It’s timing. Oh did i mention skill and knowledge training?

So the question arises:

I have coloured my hair it’s the wrong shade what can i do?

Was it one tube or bottle or a mix pack?

When you applied the color did you mix 2 things together?  Was it a twist the top asking that you shake 2 suspended liquids together or were you able to apply it straight from the bottle with out mixing anything?

If you mixed 2 things you used a long lasting semi permanent, or what the pro’s call a Demi permanent. They usually contain a very low volume of peroxide and little or no ammonia, they use a different chemical to cause the oxidation instead of ammonia. such a detergent,  {in the form alkaline solution} some have a grain alcohol derivative in them maybe even metallic salts!

If it came straight from the bottle to your hair it was a direct dye or preformed dye molecule in an alkaline solution. The alkaline liquid causes the hair shaft to swell so that the large molecules of color will penetrate slightly into the cortex sticking to the cuticle. This is the principle that the washes out in 15 – 20 shampoos works, the cuticle can’t lie completely flat again because the colored molecules are in the way so each time we shampoo or wet our hair the cuticle raises or swells slightly and the rubbing action of our hands while we lather pulls a few of them off eventually we have none left and our hair is back to nearly its original state.

Having said this continued use or applying to damaged hair you can and will get build up! porosity of hair it’s natural moisture level it’s Ph can be compromised.

DEMI PERMANENT COLOUR:

Two products mixed together much deeper deposit!

Demi  permanent colours use either low levels of ammonia or MEA {methylethylalamine}  in place of the ammonia, to oxidize  the colour molecule low level of  hydrogen peroxide less than 5vol this cause the indirect dye molecules to mature and develop into desired color. While this is considered Demi permanent because it does not lighten natural pigment with continued use it will slowly lighten the hairs natural level so could create regrowth issues and indeed over time fading issues!

The key here is not to over use and always assess the hair before any application:

                                Demi colour rich brown tone on tone deposit

The above model is a rich Brown tone on tone colour with a short textured razor cut.

Final option the one that covers fully but can create the most issues of effecting condition, deposit, banding, health and shine.

Permanent colour:

Normally mixing from a tube but in some form liquid or gel, mixing colour pigment with a peroxide mix this is a process of lift and deposit. The colour may have ammonia or be advertised as being ammonia free. MEA grain alcohol derivative in all cases the action is to change the ph of the hair open the cuticle, These products have hydrogen peroxide in them this serves to purposes it lifts your natural hair level , it also reacts with the colour molecule to help it mature or to develop it.

This is a process of lift and deposit and is permanent, many issues can arise in this choice of product from over processing to poor deposit to not attaining the correct or desired colour.

It is my personal opinion that any one want permanent colour should at least seek professional advise before embarking on this journey!

Finally a home colour correction tool:

Whilst doing research On line I came across a colour remover Product for home use not a thing I would normally promote. sold in most branches of Boot’s chemist B4 Colour remover.

The key to using any product is to follow the instruction to the latter.  Don’t take short cuts make sure you allow enough time to do this process correctly. This colour removing product is everything it claims to be I was very impressed. But remember it only removes artificial pigment if you have coloured your hair a number of times do not expect your natural colour to appear. If you have over time lifted your natural level with each colour application using permanent colour.you may be able to remove the unwanted pigment but your hair’s natural level will be lighter and in some cases very light if hair has been coloured over a long period. Remember none of these products  are a miracle quick fix. So do your re search become informed if in doubt have a professional consultation.

So before using or applying think about your choices and options: Then make a decision and live with the consequences. good luck hope this has been helpful.
