Anagen (the growth phase)
– is the period of active growth. During this stage two processes are
taking place: cells in the root of the hair divide quickly to form a new hair and then the the hair follicles start producing melanin (the pigmented proteins) which moves to the hair shaft to give it the dark colour. How long this part of the cycle lasts is determined genetically and therefore varies from person to person but on average, approximately 40% of the upper lashes will be in this phase at any given time.

Catagen (the transition phase)
– after the Anagen phase comes the short transitional phase called
Catagen. Once the hair reaches its predetermined length, they stop growing and the hair follicle begins to shrink which moves the lash to the transition phase. This phase will last around 2 – 3 weeks and no pigment is made during this time or produces any hair.

Telogen (the resting phase)
– the hair will rest in the hair follicle for around 3 – 4 months and during
this time a new hair begins to grow. As the lash grows upwards, the old hair will naturally shed or may be pulled out. Shedding is a normal process of the replacement of the old lash with a new. This new hair that has grown will emerge from the same opening as the previous one and the cycle returns back to the Anagen phase.
