Ever wonder how your lashes grow?

AWonder how you lashes grow? We always like to say knowledge is power so here’s some insight as to how your eyelashes grow!

 

Eyelashes grow just like any other hair on your body. Your genes carry a specific growth cycle to keep them growing regularly. Each hair follicle grows many hairs over your lifetime. On average, each follicle grows 20 new hairs. The growth phases are staggered to prevent periods of eyelash baldness when the growth cycle stops.

 

Anatomy and Function

You have around 90 to 150 eyelashes on the upper lid and 70 to 80 on the lower lid. They typically grow just under 1/2-inch long and have nerve sensors that cause the eyelid to shut when a speck of dust hits one. Aesthetically, they frame the eyes and they filter out foreign objects and keep them away from the eye.

 

Three Phases of Hair Growth

 

1. Anagen

 

Anagen, the active growth phase, varies in length between the sexes and from person to person, but usually ranges from 30 to 45 days. The length of this phase determines how long each hair grows. It’s genetic, and you can’t change it to make them grow faster or thicker. Only 40 percent of the upper lashes and15 percent of the lower lashes are in active growth at any one time.

 

2. Catagen

Catagen refers to the intermediate or resting phase that takes place after the anagen phase. During this lag phase, growth stops and no pigment is made. The base of the follicle shrinks up towards the surface of the skin. The phase lasts between two and three weeks.

 

3.Telogen

 

Telogen, the shedding phase, is the longest, lasting three to four months. New hair starts to grow from the follicle; as it pushes higher, the old hair will shed naturally. Since each eyelash is on its own schedule, you do not have to worry about all of them falling out at once.

 

Re-Growth

 

Q: What if you pull an eyelash, will it grow back?

 

A: Yes, eyelashes will regrow, but it take up to two months to fully replace the eyelash depending on where it was in the growth cycle. Be careful because if you lose a clump of them, each one will take a different amount of time.

 

Artificial Stimulation

 

Lash enhancing products are believed to affect the anagen phase by increasing the length of this phase and increasing the number of hairs in the growth phase simultaneously. The exact way it works is unknown.
