Question 1

What causes sparse or short eyelashes?

Accepted Answer

Sparse, short, or thin eyelashes, also called eyelash hypotrichosis, can be genetic or related to aging, hormonal changes, eyelid inflammation, frequent eye rubbing, or cosmetic practices such as lash extensions or heavy makeup use. Some people naturally have shorter lashes, while others notice thinning over time.

Question 2

How does bimatoprost help eyelashes grow?

Accepted Answer

Bimatoprost 0.03% is a prescription topical treatment that works by prolonging the growth phase of the eyelash hair cycle. With consistent use, it can promote eyelash growth, leading to increased length, thickness, and darkness of the lashes when clinically appropriate.

Question 3

How long does it take to see results?

Accepted Answer

Most patients begin to notice early changes after 6–8 weeks of consistent use. More visible improvement in lash length, thickness, and darkness typically occurs by 12–16 weeks. Continued use is needed to maintain results.

Question 4

How should bimatoprost be applied?

Accepted Answer

Bimatoprost should be applied once daily to the upper eyelid margin only, using a clean applicator. A thin line is sufficient. Avoid applying to the lower eyelids, and wipe away any excess to reduce the risk of unwanted hair growth or skin darkening.

Question 5

What happens if I stop using bimatoprost?

Accepted Answer

If treatment is discontinued, eyelashes gradually return toward their natural baseline over time. The changes are not permanent, so ongoing use is required to maintain results.

Question 6

Are there side effects I should know about?

Accepted Answer

Some patients experience mild redness, irritation, or itching around the eyes. Skin darkening at the application site or increased pigmentation of the eyelid skin can occur. Using the medication exactly as directed and applying it precisely can help minimize side effects.

Question 7

Can eyelash growth treatment be done online?

Accepted Answer

Often, yes. Teledermatology works well for eyelash growth treatment when medical history and goals are clear. In-person evaluation may be recommended if there are eye conditions, significant irritation, or other concerns.

If you develop eye pain, vision changes, or significant irritation, stop use and seek in-person evaluation.

The Data

Bimatoprost (Latisse) was traditionally a prescription glaucoma medication that was found to increase hair growth.

In a multicenter, randomized, double-masked, vehicle-controlled, parallel-group study (fancy words for a good study) with 278 patients, 78% of patients using bimpatoprost saw a significant increase in overall eyelash prominence.*

99% of women had lashes that were 106% fuller

100% of women had lashes that were 25% longer

98% of women had lashes that were 18% darker
