Hair Growth – is made up of different phases these are Anagen, Catagen and Telogen. When applying individual eyelashes, they are placed on natural eyelashes that are at the Catagen and Telogen phase never apply eyelashes that are in Anagen phase as they are still to delicate and are not strong enough to hold the extension which would result in damaging the eyelash.
Anagen – Active phase – 30 – 45 days
Catagen – Changing phase – 14 – 21 days
Telogen Resting phase – 40 – 80 days
The Hair shaft – This part of the hair extends above the skin surface but also runs through the centre of the hair. The hair shaft is composed of dead, keratinized cells which have been pushed away from the hair bulb.
The Root – The root is the portion that lies underneath the skin and inside the follicle.
The Bulb – Is the large base at the bottom of the root and this encases the Dermal Papilla. The matrix is the lower region of the bulb where the cells divide rapidly to produce the new hair structure.
