Lexapro (escitalopram) is one of the most prescribed antidepressants, and hair loss is a concern that comes up often in SSRI communities. The evidence for Lexapro specifically is sparse but real — here is what we know and, just as importantly, what we don't.
Does Lexapro Cause Hair Loss?
Hair loss is listed as an infrequent or rare adverse event in Lexapro's prescribing information. At least one published case report documented escitalopram-induced hair loss, and pharmacovigilance databases have received alopecia reports associated with its use. A large observational study by Etminan et al. found SSRIs including escitalopram had lower relative risk than bupropion (Wellbutrin), which had the highest rate in the class.
The Mechanism: Telogen Effluvium
When Lexapro causes hair loss, the mechanism is telogen effluvium — the drug shifts follicles out of the growth phase prematurely, and two to four months after starting or increasing the dose, those follicles shed. For most users, this is a transitional response: as the body adapts, shedding normalizes within three to six months even without changing the treatment.
Factors That Increase Risk
- Starting Lexapro while nutritionally depleted — low ferritin, iron deficiency, or low vitamin D worsen drug-induced telogen effluvium
- Existing androgenetic alopecia that the medication's physiological stress may accelerate
- Dose increases, which can trigger a new phase of shedding after the body had adapted
What to Do If You're Experiencing Hair Loss on Lexapro
- Do not stop Lexapro without your prescriber. Abrupt discontinuation carries genuine risks including discontinuation syndrome and return of the condition being treated.
- Tell your prescriber. Note the timing relative to when you began or changed the medication
- Check ferritin, thyroid function, and vitamin D — the most common nutritional and hormonal amplifiers of drug-induced shedding
- Support follicle nutrition. Women's Growth Complex provides zinc, selenium, biotin, and Cynatine HNS
- Be patient. SSRI-related shedding typically resolves within six to nine months as the body adapts
The Honest Comparison
Based on pharmacovigilance data, SSRIs as a class have lower hair loss rates than bupropion. Within SSRIs, there is not strong data to rank escitalopram above or below sertraline or fluoxetine specifically. If hair loss is severe and persistent, discuss alternatives with your prescriber based on the full psychiatric benefit-risk picture.
