How Your Eyelashes Grow & Why Hair Growth Stages Matter | NULASTIN

Stages of Eyelash and Eyebrow Hair Growth

Hair follicles repeatedly go through stages in a cycle of growth and resting. The entire process can take between three to four months … and every stage of hair growth matters.


  1. The first stage (Anagen) is when your hair grows a little every day (30-45 days).
  2. The second stage (Catagen) is the transition or regression phase when your hair follicles shrink, allowing the strands (bulb) to extend towards the surface (2-3 weeks). 
  3. The third stage (Telogen) is a resting phase. Your hair bulb is inactive and the hairs eventually fall out (+/- 100 days). 
  4. The Fourth stage (Late Telogen) is reassembly. This is where new follicles are formed. Think of it as the re-awakening process before the lashes start back into growth phase.


So, how do you keep your hair growing more and resting less?

The secret to more hair growth is to keep the first stage (Anagen) happening longer. Then, shorten the second phase (Catagen), which further extends the growth phase lifecycle. Additionally, by strengthening the hair follicle in the third resting (Telogen) phase, you’ll protect the follicle from dying. Finally, you can alter the course of hair loss by protecting the hair follicle during its re-awakening phase. Imagine having the power to make this happen?


Using groundbreaking science, NULASTIN® LASH & BROW serum addresses every phase of the eyelash and eyebrow growth cycle. The formula is clinically proven to increase lash length by 61% and lash density by 120% in 12 weeks. 

Timing is everything.

Only about 40% of your upper eyelashes and 15% of your lower eyelashes are typically in the active stage of the hair growth cycle. Everyone is unique. Therefore, it may be a timing issue for eyelash and eyebrow changes once serum protocol starts. If the majority of your lashes are in the third stage (for example), you may need to use the serum longer to see changes. Remember, this stage lasts 100+/- days.


Some individuals may have damaged follicles that need rejuvenation, which also takes time. If the hair follicle is dead – Princess Bride level “All Dead” and not “Mostly Dead” – then, nothing can revive it.

Make Every Stage of Hair Growth Matter

Another way to enhance the performance of your eyelash and eyebrow growth cycle is a holistic approach.
