Too Yellow
Hair that is too yellow has suffered the loss of pigment
described above. To correct this the yellow needs to be toned down.
This is achieved by using a colour from the opposite side of the
colour chart. Exactly opposite is not always needed as we only want
to tone the colour so if you look at the colour chart orange/yellow
is opposite blue/green and blue/green is the base for ash toners
.....simple!
Poor grey coverage
There can be several reasons for poor coverage of grey hair.
Resistant
Some grey hair is just very resistant to colour probably
due to a very tight and compact cuticle (link to cuticle graphic)
one solution is to increase the strength of the peroxide used in
the colour.
Under strength product
With many different strength products on the market
it's easy to be using the wrong one -- semi's, quasi colours, colour
baths, tints etc. etc. all do different jobs. Some of these are
designed not to give total coverage for a more natural effect. Another
possibility is that air has got into the product and it has lost
its strength.
A barrier
It's also possible a barrier has formed stopping the
product from penetrating into the hair. The most common reason for
this in recent years is the increased use of gels and wax. Hair
spray could also cause this problem. Another likely cause is a two-in-one
shampoo-conditioner which can quickly build a barrier on the outside
of the hair.
Too dark or too even
Too Even
Nothing gives a hair colour away, or looks more artificial
than a flat dark even colour. Only the very darkest hair is all
one colour and even black hair tends too have blue tones in it.
Our eyes and brains are scanning all the time but we simply don't
notice the ‘normal’ however we take a second look if
something isn't quite right. Darker roots and lighter ends are ‘normal’
but a dead even light or dark colour isn't.
Adding darker and lighter colour to the hair not only
makes it look more natural but adds life texture and energy to the
hair. This can be done to dramatic effect or just to give subtle
texture.
Too Dark
Once you've made your hair too dark by putting a colour
on it and then want it to be lighter you have a slight problem,
because colour doesn't easily lift colour. In fact to lift artificial
colour out of the hair usually requires bleach and bleach on coloured
hair tends to be not good for the condition of the hair and also
unpredictable! This is probably a job for a professional.
Colour fade/red fade
This is very similar to Too Light/Too Yellow. The graphic
there shows the open cuticle that lets colour out of the hair with
reds in particular bleeding out very easily. Most colour houses
have worked very hard on improving the ‘stickability’
of their reds but fading is still a problem.
The best way of preserving your beautiful new colour
is to make sure you have a low P.H. shampoo and conditioner and
not one that merely claims on the label ‘for colour treated
hair". The marketing man who knows nothing about shampoo won't
get you that easy any more!
