Clomid raises estrogen levels dramatically before causing a sharp decline, and this hormonal crash can trigger telogen effluvium in susceptible women. If you are undergoing IVF or taking Clomid, tracking your hair density alongside your treatment cycles gives you the data to understand whether your shedding is treatment-related or something else entirely.
Why Fertility Treatments Cause Hair Loss
Fertility medications work by manipulating the hormones that regulate ovulation. Clomid (clomiphene citrate) blocks estrogen receptors, tricking the body into producing more follicle-stimulating hormone (FSH) and luteinizing hormone (LH). IVF protocols use gonadotropins to stimulate multiple eggs, creating estrogen levels 10 to 20 times higher than a normal cycle.
The problem is not the high hormone levels themselves. It is the rapid decline afterward. When estrogen drops sharply after egg retrieval or after a failed cycle, hair follicles that were sustained by high estrogen levels shift into the telogen (resting) phase simultaneously. This synchronized shedding appears 2 to 4 months later.
This mechanism is identical to postpartum hair loss, where the estrogen drop after delivery triggers the same pattern.
Step 1: Establish Your Baseline Before Treatment
Take your first density scan with myhairline.ai before you begin any fertility medication. This baseline is critical because it gives you a reference point that separates pre-existing thinning from treatment-induced shedding.
Record these details in your tracking notes:
- Current cycle day and date
- Any existing hair loss concerns
- Current medications (prenatal vitamins, thyroid medication, etc.)
- Photos of your part line and temples
Your baseline scan should cover at least three areas: the frontal hairline, the mid-scalp part line, and the crown. These are the regions most affected by hormonal telogen effluvium.
Step 2: Log Each Fertility Cycle
Create a treatment log entry for every cycle. Include the following data points:
| Data Point | Example |
|---|---|
| Cycle start date | Feb 1, 2026 |
| Medication and dose | Clomid 100mg, days 3 to 7 |
| Trigger shot date | Feb 12, 2026 |
| Egg retrieval / ovulation date | Feb 14, 2026 |
| Cycle outcome | Negative / Positive / Cancelled |
| Estrogen peak (if known) | 2,400 pg/mL |
This information becomes valuable when you compare it against density readings taken 2 to 4 months later. A density dip that aligns exactly with the post-cycle window confirms a hormonal cause rather than androgenetic alopecia.
Step 3: Schedule Density Scans on a Fixed Cadence
During active fertility treatment, scan every two weeks. This frequency captures the onset and progression of any shedding episode without gaps in your data.
Here is a recommended scanning schedule:
- Day 1 of each cycle: Scan before starting medication
- 2 weeks post-retrieval or ovulation: Scan to capture the immediate hormonal shift
- 6 weeks post-cycle: Scan during the telogen effluvium onset window
- 12 weeks post-cycle: Scan to measure peak shedding (if it occurs)
If you are doing back-to-back IVF cycles, the hormonal events compound. Your tracking data will show whether density stabilizes between cycles or whether cumulative shedding is occurring.
Step 4: Identify the Shedding Pattern
Fertility-related shedding has a distinct pattern that separates it from androgenetic alopecia:
| Feature | Fertility-Related Shedding | Androgenetic Alopecia |
|---|---|---|
| Distribution | Diffuse, all over scalp | Concentrated at hairline and crown |
| Onset timing | 2 to 4 months after hormonal event | Gradual, over months to years |
| Hair caliber | Normal thickness hairs shed | Miniaturized, thin hairs |
| Recovery | Full regrowth within 6 to 12 months | Progressive without treatment |
| Pull test | Positive during active shedding | Usually negative |
Your myhairline.ai density data will show whether the thinning is diffuse (spread evenly) or patterned (concentrated in specific zones). Diffuse thinning that correlates with your cycle log confirms a telogen effluvium diagnosis.
Step 5: Track Recovery After Treatment Ends
Once your fertility treatment concludes, whether through a successful pregnancy or a decision to pause, continue scanning monthly for at least 9 months. Recovery data is just as important as the shedding data.
Expect this general timeline:
- Months 1 to 3 after final cycle: Shedding may continue or peak
- Months 3 to 6: New growth begins, density stabilizes
- Months 6 to 9: Visible density recovery
- Months 9 to 12: Return to baseline for most women
If your density has not returned to within 10% of your pre-treatment baseline by month 12, this is a signal to consult a dermatologist. Persistent thinning beyond 12 months may indicate that the fertility treatment unmasked underlying androgenetic alopecia.
When to Share Your Data with Your Doctor
Your fertility specialist and dermatologist both benefit from seeing your tracking data. Export your density timeline from myhairline.ai and bring it to appointments when:
- Shedding begins before the expected 2 to 4 month window
- Density loss exceeds 20% from baseline
- Shedding is concentrated in the hairline or crown rather than diffuse
- Recovery has not begun by 6 months after the final cycle
- You are starting a new round of treatment and want to discuss protective options
Documenting the correlation between treatment dates and density changes gives your medical team objective data instead of subjective impressions.
Protective Measures During Fertility Treatment
While you cannot prevent the hormonal fluctuations that cause shedding, you can support your hair during treatment:
- Continue prenatal vitamins with iron and biotin
- Avoid tight hairstyles that add traction stress
- Use gentle, sulfate-free shampoo
- Discuss low-dose minoxidil (2%) with your dermatologist if appropriate for your situation
- Maintain protein intake above 50g per day
Minoxidil at 2% concentration is generally considered compatible with fertility treatment, but always confirm with your reproductive endocrinologist before adding any medication.
Start Tracking Before Your Next Cycle
The best time to begin tracking is before your next fertility cycle starts. A single baseline scan takes 60 seconds and creates the reference point that makes all future data meaningful. Visit myhairline.ai/analyze to take your first scan and set up your fertility treatment tracking log.
