Core Definition & Basic Anatomy of Eyelash

Eyelash refers to fine, curved hair growing along upper and lower eyelid margins that block dust and debris to protect eye health. Unlike scalp hair, natural eyelashes have an average growth cycle of 30 to 90 days, with around 150 to 200 individual lashes growing on the upper eyelid, and 70 to 100 lashes on the lower lid. In practice, our lash technicians at New City Eyelash have served over 120,000 clients since 2014, we found that over 70% of excessive lash shedding cases are triggered by improper makeup removal, rather than inherent lash health problems.

Q: What core functions do eyelashes serve besides protecting eyes?

Studies show that eyelashes also act as a sensory trigger: when a tiny object touches lash hairs, the eyelid will automatically close as a protective reflex, even without conscious notice from the user. They also play an irreplaceable role in facial aesthetic presentation, as full, neat lashes can immediately brighten the entire eye area without extra makeup.

Q: Is it normal to lose 5 to 7 natural lashes every day?

It is 100% normal for the human body to shed 3 to 8 natural eyelashes per day during the regular growth cycle, no extra intervention is needed. Only when daily lash shedding exceeds 15 hairs for 2 consecutive weeks, you need to check for potential irritation triggers such as expired mascara or wrong facial cleanser getting into lash roots.

3. Apply a thin layer of hypoallergenic lash nutrient serum along the lash root line 1 time per day, avoid getting the product directly into your eyes

Q: Can applying castor oil on eyelashes help them grow longer?

Actual test from our 2026 client trial shows that pure cold-pressed castor oil can moisturize lash hairs to reduce breakage, but it cannot make lash hairs grow beyond their inherent genetic maximum length. It does not contain active ingredients that can stimulate lash follicles to enter the growth phase earlier.

Q: What common daily habits will damage your natural eyelashes unknowingly?

Sleeping with makeup on, using waterproof mascara that is hard to remove regularly, rubbing your eyes when you feel tired, and sharing your mascara tube with friends are all top bad habits that can lead to lash breakage or follicle infection easily.

Q: How long should I take a break from lash extensions to let natural lashes recover?

Q: Are DIY lash extension kits sold online safe for home use?

Most at-home DIY lash extension kits sold in the market contain glue with higher irritant ingredients, and users without professional training are very likely to stick extensions directly onto the natural lash root too close to the skin, which will lead to eye irritation and even temporary vision blurriness. It is highly recommended to get extension service from a certified professional lash technician.
