Our hair grows and to regenerating in repetitive cycles and each cycle can into three phases be divided. Anagenphase Catagen phase Telogenphase The Anagen phase is the growth phase and about 85% of the hair on the scalp is in this phase is at any time possible. The duration of this phase is 2-6 years. In one year, the hair grows approx. 10 cm. The Anagenphase becomes by the Katagen phase, which follows from 3-6 weeks duration. During this phase become the hair follicles shrinks on approximately 1/6 of the normal length in Anagen. The Katagen phase by the Telogenphase one follows. During this phase the hair grows not, but remains attached on the follicles. At the end of the Telogenphase, the hair steps into a new Anagenphase again, where the dermal Papille forms and for the basis of the follicles to interconnect, around new regenerating of the hair. Hair growth is after a continuous process the previous cycle.
With healthy persons, the hair fiber grows at a speed of approximately 0.35 mm/day on the scalp. Also in normal scalp, the total number of the follicles is constant in the growth phase. It is the duration of the Anagenphase that the maximum hair length certainly and also the number of hair will drop lock those the Telogenphase and. If it to an imbalance into the normal cyclic process regenerating the hair or if the follicle is damaged, hair loss or Alopezie arises. Factors, normal regenerating of the hair A multiplicity of factors can itself on normal cyclic process regenerating the hair. Some the common factors are medicines, irradiation, chemotherapy, the exposition opposite chemicals, wrong hair styling, hormoneal and nourish-conditioned factors, thyroid illnesses, generalized or local skin diseases and stress. Or hair fiber can do several of these factors like loose Anagen syndrome or irreversible hair loss such as Alopezie to serious damage. Capitis also a cause of the hair loss knows infections such as Tinea. Temporary interruption the cyclic process regenerating the hair Regenerate the hair cannot also by a temporary interruption the cyclic process not be affected. Some the factors, those contain temporary interruption of the cycle are regenerating the hair after the birth of a baby, surgery, anaesthesia received etc. strong cancer therapies often lead to Effluvium, one of the main causes of hair loss for those, the one chemotherapy Anagen. Appropriate information about the causes hair loss, becomes you in treatment against hair loss. Inform about the exact mechanisms of hair growth and remain yourselves, like it cycles. In addition have a short overview of the factors and diseases, which affect the normal regenerating of the hair. |
