 | The Texture Of The Hair
The texture or coarseness, the diameter of
the hair, is directly dependent on the diameter
of the follicle. Fine hair grows out of
small hair follicles, coarse hair from larger.
During the course of a life cycle the hair follicle
can alter its diameter and thus the coarseness
of the hair growing out of it.
The finest form of hair is vellus hair. It
covers most of an infant’s body. The coarsest
form is terminal hair, the hair on the
scalp, sex-specific areas of hair as well as
eyebrows

 | The Quality Of The Hair.
All properties that give the hair natural
shine, manageability and resistance contribute
to the quality of the hair and enable
the hairdresser to give it the desired style
and colour.
The most important criteria for the shape of
the hair – for instance straight or curly – are
the cross-section surface of the hair and the
structure of its surface (smooth, rough).

 | The Length Of The Hair
The maximum achievable length of a hair
depends directly on the length of the
growth phase (anagen). All body hair grows
at a rate of about 0.33 mm per day. However,
whereas for instance eyebrows end the
anagen phase after one month, i.e. hardly
become longer than 1 cm, the hair on the
scalp continues to grow over a period of
years (for hip-length hair about 6 years).

 | What Determines The Texture Of Hair
Texture, length and quality of hair depend
on the location (on the body or the scalp) as
well as the sex, hereditary disposition and
age of the person.
The texture of different types of hair is directly dependent
on the diameter and volume of the corresponding
hair follicle. The length of the hair is dependent on the
duration of the growth phase (e.g. several years for
scalp hair, approx. one month for eyebrows).The quality
of hair is affected by the factors which provide it with

 | How Does Hair Grow
The growth cycle of hair:
1.Growth phase (anagen): approx. 80 % of scalp hair is in the
anagen phase.
2. Transitional phase (catagen): approx. 1 % of scalp hair is in the
catagen phase. The catagen phase lasts 2-3 weeks.
3. Resting phase (telogen): approx. 19% of scalp hair is in the
telogen phase.
The growth phase (anagen): During this phase the hair grows continuously. Scalp hair can, for example, grow continuously
for a period of 6 years at a rate of about 1 cm per month. As a rule,

 | What Is The Structure Of Hair
Hair consists of the hair shaft, the papilla,
the matrix trichocytes and the daughter cells
of the latter, the trichocytes. During the
course of multiple processes the trichocytes
are transformed into long spindle cells, the
keratinised components of the hair shaft.
The melanocytes can be found on the dome
of the hair papilla.
These produce the melanin,
transmit it to the trichocytes and coat
the hair fibre with its natural colour.
A fine network of blood vessels surrounds a
