Hypotrichosis of the Eyelashes — Glossary Definition
Hypotrichosis of the eyelashes means eyelashes are inadequate, sparse, or not as prominent as expected. It is the clinical term used in Latisse labeling for eyelash growth treatment.
What does hypotrichosis mean?
Hypotrichosis means reduced or insufficient hair growth. When applied to eyelashes, it describes lashes that are inadequate, sparse, short, or not prominent enough for the patient’s goals. Patients usually describe the concern as thin lashes rather than using the medical term.
Is it always cosmetic?
No. Some patients want fuller lashes for cosmetic reasons, but lash loss can also reflect medical problems. Alopecia areata, trichotillomania, chemotherapy, trauma, eyelid inflammation, and eye disease can all change eyelashes. Those causes need diagnosis, not just a cosmetic prescription.
What does Bidwell treat?
Bidwell treats adults ages 18-64 seeking upper-eyelash enhancement when the screening history does not suggest eye disease or medical lash loss. The visit is clinician-reviewed and treatment is provided only if appropriate.
When is in-person care better?
In-person care is better for sudden lash loss, patchy lash loss, eyelid scarring, pain, swelling, infection, vision change, chemotherapy-related loss, pulling behaviors, or any history of glaucoma, ocular hypertension, or prescription eye-drop use.
How is it different from normal variation?
Not everyone with naturally short or sparse lashes has a disease. Hypotrichosis is a clinical term used to describe inadequate eyelashes, but the decision to treat still depends on goals, safety history, and whether there are signs of another condition. Online care is most appropriate when the concern is stable and cosmetic.
Why does the distinction matter?
If lashes are suddenly falling out, patchy, painful, inflamed, or associated with eyelid changes, the problem may not be cosmetic hypotrichosis. A prescription for bimatoprost could delay the right diagnosis. That is why Bidwell screens out medical lash loss and eye symptoms.
What to expect
Eyelash-growth treatments are not instant. Results are typically gradual, and consistency matters.
Safety basics
- Stop and seek care for eye pain or vision changes.
- Use careful hygiene with applicators; do not share.
- Contact lens wearers should follow handling guidance.

Frequently asked questions
Can I use it with contact lenses?
Many people can, but lens hygiene and timing matter. Follow clinician guidance and stop if irritation is significant.

Clinical context
This term is used on Bidwell pages to support clear, consistent language across guides and treatment pages. The goal is understanding and safe next steps, not self-diagnosis.
When to seek in-person care
- Severe symptoms or rapidly worsening symptoms
- Pregnancy or possible pregnancy
- Unclear diagnosis or treatment failure
How Bidwell uses this definition
Bidwell’s public pages are written so patients can understand what a clinician means, and so the same term is used consistently across related treatment pages, clinical notes, and guides. This is intentionally not a full textbook chapter — it’s a practical definition with safety boundaries.
If you are reading this because you are trying to self-diagnose, a good rule is: if you are uncertain what the diagnosis is, or you have red flags (severe pain, fever, pregnancy, eye involvement, rapid worsening), in-person evaluation and testing is often the safest next step.
Questions that help a clinician
- When did symptoms start and how have they changed day-by-day?
- What have you already tried, and did anything partially help?
- Any prior diagnosis of the same condition?
- Any pregnancy possibility or immune suppression?
- Any new medications, allergies, or recent antibiotic use?
