Shedding More Lashes Due to Latisse?

As the eyelash hairs get pushed from a resting phase to a growth phase, the resting hair will fall out.  It probably happens in everyone, but some the effect is more dramatic.  With Latisse, the percent of hair in the growth phase is higher.  Keep using the Latisse, at least 6-8 weeks before you notice the growth.

This is extremely rare but I have gotten feedback from one patient who has reported shedding during the initial application of Latisse. Thankfully, she was able to regrow her lashes after 6 weeks of continuous application. I believe the eyelashes go through different hair cycles just like the scalp hairs, e.g. anagen (growth phase), catagen (breakdown phase), and telogen ('limbo' phase between anagen and catagen). It is possible for few predisposed individuals, the eyelashes may be pushed to the 'telogen' phase by Latisse but this phenonmenon should be transient.

Latisse should not make you lose lashes. I would try to not firmly manipulate or put tension on the lashes as I apply to latisse to not damage the lashes you have. That could cause some lashes to fall out.
