Compounding pharmacies now fill up to 25% of dermatologist-prescribed hair loss treatments, creating custom blends of Minoxidil, Finasteride, and other active ingredients tailored to individual patients. Unlike mass-produced medications with standardized clinical trial data, compounded formulations have no large-scale efficacy studies behind them. This makes personal tracking essential: your density data is the only evidence that your specific formulation works for your specific hair loss pattern.
What Compounded Hair Loss Formulations Include
A compounding pharmacy can combine multiple active ingredients into a single topical or oral formulation. Common components include:
| Ingredient | Typical Concentration | Purpose |
|---|---|---|
| Minoxidil | 5% to 15% | Vasodilator, promotes regrowth (40-60% efficacy) |
| Finasteride | 0.025% to 0.1% topical | DHT blocker (80-90% halt loss, 65% regrowth oral) |
| Dutasteride | 0.01% to 0.05% topical | Stronger DHT blocker, off-label |
| Tretinoin | 0.01% to 0.025% | Enhances Minoxidil absorption |
| Latanoprost | 0.005% | Prostaglandin analog for follicle stimulation |
| Biotin | Varies | B-vitamin for hair structure support |
| Caffeine | 1% to 2% | May stimulate follicle proliferation |
The advantage of compounding is customization. Your dermatologist can prescribe a formula that targets your specific needs, combining a DHT blocker with a growth stimulator and an absorption enhancer in one application.
The disadvantage is uncertainty. No clinical trial has tested your exact formulation at your exact concentrations in your exact carrier base. Your tracking data fills that evidence gap.
How to Track Your Compounded Formulation
Step 1: Document Your Formulation Details
Before you start tracking, record every detail of your compounded prescription:
- Active ingredients and their exact concentrations
- Carrier base (cream, foam, solution, or gel)
- Prescribing physician and rationale for the formulation
- Pharmacy name and any batch or lot numbers
- Application instructions (frequency, amount, areas)
This documentation matters because compounding pharmacies may adjust formulations between refills. If your density data changes after a refill, you need to know whether the formulation changed too.
Step 2: Establish Your Pre-Treatment Baseline
Take your first set of standardized density photos before applying the compounded formulation for the first time. Use myhairline.ai to capture images from consistent angles under consistent lighting.
Record your baseline metrics:
- Hair density per cm2 in affected areas
- Miniaturization ratio (if available from trichoscopy)
- Current Norwood stage classification
- Any existing treatments you are continuing alongside the compounded formula
Step 3: Track Consistently for 4 to 6 Months
Compounded formulations containing Minoxidil need 4 to 6 months to show results. Formulations with Finasteride may take 3 to 6 months. Take density photos every 2 weeks and log the following:
- Application compliance (did you apply as prescribed?)
- Any side effects (scalp irritation, dryness, oiliness, systemic effects)
- Shedding events (initial shedding is common with Minoxidil and Finasteride)
- Changes in hair texture or thickness
- Refill dates and any formulation adjustments
Step 4: Evaluate and Adjust
After 4 to 6 months, review your density curve with your prescribing physician. The data should answer three questions:
- Is density increasing, stable, or declining?
- Are the side effects acceptable relative to the benefits?
- Should any concentrations be adjusted up or down?
Compounded vs. Standard Formulations: What to Compare
If you previously used standard over-the-counter Minoxidil (5% topical) or prescription Finasteride (1mg oral), your historical tracking data becomes invaluable. Compare:
| Metric | Standard Formulation | Compounded Formulation |
|---|---|---|
| Density change at 3 months | Your recorded data | Your recorded data |
| Density change at 6 months | Your recorded data | Your recorded data |
| Side effect frequency | Your recorded data | Your recorded data |
| Application compliance | Your recorded data | Your recorded data |
| Monthly cost | Your recorded data | Your recorded data |
This head-to-head comparison using your own data is more relevant than any published study, because it reflects your biology, your hair loss pattern, and your actual compliance rate.
Why Tracking Matters More for Compounded Treatments
Standard medications like Rogaine (Minoxidil 5%) and Propecia (Finasteride 1mg) have decades of clinical trial data supporting their efficacy. When you use these products, you have reasonable expectations based on large-scale studies.
Compounded formulations lack this external evidence base. The specific combination of ingredients, concentrations, and carrier bases in your prescription has likely never been studied in a controlled trial. Your personal tracking data serves as your own single-subject clinical trial.
This is not a weakness of compounded treatments. It is simply a reality that makes tracking non-negotiable. Many patients report excellent results from compounded formulations, but those results are highly individual.
Red Flags to Watch For
Track these warning signs and discuss them with your physician:
- No improvement after 6 months of consistent use: The formulation may need adjustment
- Worsening density: Could indicate the formulation is causing irritation that damages follicles
- Persistent scalp irritation: The carrier base or concentration may not suit your skin
- Systemic side effects: Topical Finasteride can still be absorbed systemically, causing the same side effects as oral Finasteride (reported in 2-4% of users)
- Inconsistent refill quality: Density changes that correlate with new batches may indicate formulation variability

Track Your Compounded Formula Response
Upload your first set of scalp photos at myhairline.ai/analyze before starting your compounded formulation. With objective baseline data, you and your dermatologist can make evidence-based decisions about whether your custom blend is delivering the density gains it should.
