GLP-1 telogen effluvium doesn't just thin scalp hair — eyelashes and eyebrows shed in parallel for users on Ozempic®, Wegovy®, Mounjaro®, or Zepbound®. Topical lash/brow serums with peptides + prostaglandin analogs stimulate follicle regrowth. This guide compares five serums for users dealing with lash + brow thinning alongside scalp shedding.

1. Best overall — GrandeLASH-MD Lash Enhancing Serum
Peptides + vitamins + amino acids. 12-week protocol. ~$70/2 mL.
GrandeLASH® is the consumer-favorite lash serum. Visible lash improvement at 6-8 weeks. No prostaglandin analog = lower side effect risk than prescription Latisse. Strong cult following.

Frequently Asked Questions
Why do lashes thin on GLP-1?
Telogen effluvium affects ALL hair follicles — scalp, eyelashes, eyebrows, and body hair. Same mechanism (rapid weight loss stress → follicles shift to resting phase). Lashes often noticeable because they affect appearance directly.
GrandeLASH vs Latisse?
GrandeLASH: peptide-based, OTC, $70, slower onset (6-8 weeks). Latisse: prostaglandin-based, Rx, $140, faster results (4-6 weeks). For most users: GrandeLASH is sufficient. For severe lash loss: Latisse with telehealth Rx.
Are these safe?
Peptide-based serums (GrandeLASH, Revitalash, Babe Lash): minimal side effects. Latisse (bimatoprost): rare iris pigmentation changes in very rare cases — generally safe but requires Rx.
How to apply?
Single thin line at the base of the lash line, once daily before bed. Like eyeliner application. Avoid getting in the eye itself. For brows: full brow application morning + evening.
Safe with peptide and GLP-1 protocols?
Yes — minimal systemic absorption. No interaction with semaglutide, tirzepatide, BPC-157, or GH peptides.
How long until I see results?
Length increase: 4-8 weeks. Fullness increase: 8-12 weeks. Maximum effect: 16+ weeks. Stopping use returns lashes to original length within 3-4 months.
