Unlike skin, hair cannot repair itself. It is a
balance of protein and moisture, which keeps it in
good condition with natural shine.
Protein levels in hair are around 83% to 87%.
Moisture levels are about 3%. The only difference
between your hair and nails is the 3% moisture. If
this essential balance is maintained, the hair will
stay healthy, strong and in good condition.
On the outside of hair are transparent layers of
interlocking scales, which are called the cuticle.
We have about 7 to 11 layers all wrapped around
the delicate inner structure.

pH Balance
• This is a measure of acidity and
alkalinity
• It ranges from 0 to 14
• 7 is neutral – pure water
• The ideal level for our hair and skin
is between pH 4.5 and 5.5
• Above 5.5 the hair starts to open
and below 4.5 it starts to contract
• For a permanent hair colour to
work, we have to open the hair by
taking it out of its ideal pH and take
it above pH 8
• To ensure the best possible
condition of the hair we have to
return it to its ideal pH

Colouring Hair 2
For a permanent hair colour to work, we have to lift
the cuticle and allow the permanent colour into the
hair. The only way to do this is to alter the pH of the
hair.
All permanent hair colours use this method.
There are 2 ways to open the cuticle. The traditional
method uses ammonia, which is highly effective, but
can damage the hair. The alternative method uses the
latest technology, where the active ingredient for
raising the pH is mildly alkaline and acts as a
conditioning agent.

Pre-Lightening and
Highlighting Hair
Lightening agents provide a greater degree of lift by oxidising
the natural colour pigment in the hair.
To avoid any damage to the hair when pre-lightening or
highlighting, use a product which is:
Ammonia-free: to prevent excess swelling and damage to the
hair
Dust-free: to avoid inhalation of the product
Made with added wheat proteins: to strengthen the hair
during the process
For on-the-scalp applications, use a protective oil

Perming and
Straightening Hair
Perming and straightening involves altering the physical
make-up of the hair.
To ensure hair is left healthy, choose a product which is:
Ammonia-free: to prevent excess swelling and damage to
the hair
Thioglycolate-free: a relaxing agent, which can irritate the
skin and scalp
pH balanced: hair is left around its natural pH, minimising
any damage caused by the process

Caring for Hair
Hair in good condition should not only look healthy, but when
wet, should be able to stretch by 30% of its length and
return, without any damage to the hair.
To keep hair in its optimum condition, it should be treated
with shampoos, treatments and conditioners.
Shampoo: to clean hair
Treatment: to repair, rebalance and reconstruct hair
Conditioner: to close the cuticle and add shine
