Kirkland Minoxidil is the most purchased hair loss product in Canada due to Costco's national distribution network. If you are using it, tracking your density response with AI analysis turns your daily routine into measurable data.

Kirkland Minoxidil in the Canadian Market
Kirkland Signature Minoxidil 5% is available at every Costco location across Canada. It is the generic equivalent of Rogaine, containing the same active ingredient at the same concentration, approved by Health Canada for the treatment of androgenetic alopecia.
The cost difference makes Kirkland the default choice for most Canadian minoxidil users:
| Product | Canadian Price (Approximate) | Supply |
|---|---|---|
| Kirkland Minoxidil 5% Foam | $35 to $50 CAD | 6-month supply |
| Kirkland Minoxidil 5% Liquid | $30 to $45 CAD | 6-month supply |
| Rogaine Foam (brand name) | $70 to $100 CAD | 3-month supply |
| Rogaine Liquid (brand name) | $60 to $90 CAD | 3-month supply |
Both products deliver the same clinical outcome. Minoxidil, regardless of brand, produces moderate regrowth in 40% to 60% of users. The difference is purely economic, which is why Kirkland dominates the Canadian market.
How to Track Kirkland Minoxidil Results
Step 1: Baseline Before Starting or Within Week 1
Take 5 to 7 photos of your key scalp zones with myhairline.ai. If you have already been using Kirkland Minoxidil for a few weeks, start tracking now and treat your first reading as a delayed baseline.
Record these starting measurements:
| Metric | What to Capture |
|---|---|
| Frontal density | Follicles per cm2 at the hairline |
| Crown density | Follicles per cm2 at the vertex |
| Temple density | Follicles per cm2 at each temple |
| Product formulation | Foam or liquid |
| Application frequency | Once or twice daily |
| Start date | Day zero of Kirkland use |
Step 2: Apply Consistently and Log Every Application
Minoxidil works best with twice-daily application. The standard protocol is 1 mL of liquid or half a capful of foam applied to dry scalp in the morning and evening. Consistency matters more than any other variable.
Track your adherence:
- Perfect adherence: Two applications per day, every day
- Good adherence: Occasional missed single applications (fewer than 3 per month)
- Poor adherence: Multiple missed days per month
Studies show that treatment response correlates directly with adherence. If your density is not improving, check your adherence log before concluding the product does not work for you.
Step 3: Photograph Every 2 Weeks for 6 Months
Minoxidil requires 4 to 6 months of consistent use before visible results appear. The first 2 to 4 weeks often produce increased shedding as miniaturized hairs are pushed out to make room for thicker anagen growth. This initial shed is a positive sign, not a reason to stop.
Upload your bi-weekly photos to myhairline.ai. The AI calculates density per cm2 and plots your readings on a timeline.
Expected timeline for Kirkland Minoxidil results:
| Month | What to Expect |
|---|---|
| Month 1 | Possible increased shedding (normal) |
| Month 2 | Shedding subsides; no visible change yet |
| Month 3 | Early vellus hairs may appear; density readings may start rising |
| Month 4 | Vellus hairs thickening; measurable density improvement in responders |
| Month 5-6 | Visible improvement in 40% to 60% of users |
| Month 12 | Maximum results typically reached |
Step 4: Compare Foam vs Liquid Response
If you switch between Kirkland foam and liquid formulations, track the transition. Some users respond differently to the two vehicles due to propylene glycol in the liquid formulation (which can cause scalp irritation) versus the alcohol-based foam.
| Factor | Kirkland Liquid | Kirkland Foam |
|---|---|---|
| Active ingredient | Minoxidil 5% | Minoxidil 5% |
| Vehicle | Propylene glycol solution | Alcohol-based foam |
| Scalp irritation risk | Higher (propylene glycol) | Lower |
| Application ease | Dropper, more precise | Foam, faster but less precise |
| Drying time | 15 to 20 minutes | 5 to 10 minutes |
| Price (Costco Canada) | Slightly cheaper | Slightly more expensive |
Canadian-Specific Tracking Considerations
Canadian users have a few region-specific factors to account for in their tracking protocol:
Seasonal variation: Canadian winters mean months of dry indoor heating, which can affect scalp condition and potentially influence density readings. Log the season alongside your density data so you can distinguish seasonal fluctuations from treatment effects.
Costco availability: Kirkland Minoxidil occasionally goes out of stock at specific Costco locations. A gap in treatment of more than 2 weeks can reset your progress. Keep a backup supply to avoid interruptions.
Dermatologist access: Canadian wait times for dermatology referrals can range from 3 to 12 months depending on province. Having a structured density timeline from myhairline.ai when you do get an appointment maximizes the value of that visit.
Interpreting Your Kirkland Tracking Data
After 6 months of consistent tracking:
- Density increase of 10% or more: You are a responder; continue Kirkland Minoxidil indefinitely
- Density increase of 3% to 10%: Moderate response; consider adding adjunct treatments like ketoconazole shampoo or finasteride
- Density flat (within 3% of baseline): Minimal response; discuss adding finasteride (80-90% halt, 65% regrowth) with your doctor
- Density decline despite adherence: Minoxidil alone may not be sufficient for your degree of hair loss; a combination approach is warranted

Frequently Asked Questions
How do I track Kirkland Minoxidil results in Canada?
Start by taking baseline density photos with myhairline.ai before your first application or within the first week. Then photograph the same scalp zones every 2 weeks under identical lighting conditions. Upload each set to myhairline.ai for AI density analysis. After 4 to 6 months of consistent tracking, your density timeline will show whether Kirkland Minoxidil is producing measurable follicle density improvement in your specific case.
Is Kirkland Minoxidil the same as Rogaine in Canada?
Yes. Kirkland Minoxidil and Rogaine contain the same active ingredient (minoxidil 5%) at the same concentration. Kirkland is manufactured to the same Health Canada standards as Rogaine. The difference is branding and price. Kirkland Minoxidil from Costco Canada typically costs 40% to 60% less than brand-name Rogaine at Canadian pharmacies. Clinical efficacy is identical between the two products.
Can I use my Kirkland tracking data at a Canadian dermatology appointment?
Yes. myhairline.ai generates PDF tracking reports with timestamped density readings, Norwood stage assessments, and side-by-side photo comparisons. Canadian dermatologists can use this data to assess your treatment response objectively. Bringing a structured density timeline to your appointment gives your doctor quantifiable evidence rather than subjective impressions about whether your treatment is working.
