Minoxidil is one of the most established over-the-counter options for treating certain types of hair loss. But if you're new to minoxidil, the choices can be confusing.
5% or 2%? Foam or liquid? Kirkland or Rogaine? Men's or women's?
This guide covers the basics so you can better understand the products you're shopping for and, most importantly, follow the directions provided with the specific product you choose.
What Is Minoxidil?
Minoxidil is the active ingredient found in many topical hair-regrowth products, including products sold under brands such as Rogaine and Kirkland Signature.
Topical minoxidil is applied directly to the scalp. In the United States, FDA-regulated OTC minoxidil products are labeled for hair regrowth for specific patterns of hair loss and populations. Minoxidil products are also marketed as non-prescription drugs in Canada.
The important distinction is that minoxidil is the active ingredient; Rogaine, Kirkland Signature and other names are brands of products containing it.
How Does Minoxidil Work?
Hair naturally moves through different phases of growth and rest. Minoxidil can help promote hair regrowth in people with certain patterns of hair loss.
Results aren't immediate. Hair grows slowly, which means consistent use over a period of months may be required before changes become noticeable.
And minoxidil isn't a permanent cure for hair loss. Continued use is generally required to maintain regrowth. If treatment is discontinued, newly regrown hair may eventually be lost.
2% vs. 5% Minoxidil
Two concentrations you'll commonly encounter are 2% and 5% minoxidil.
Don't assume that choosing the highest percentage or applying more product will produce faster results.
The correct concentration and frequency depend on the particular product and the person for whom it is labeled. Always follow the Drug Facts label or package directions for the product you're using.
Foam vs. Liquid Minoxidil
Both formats deliver minoxidil to the scalp, but the experience can be quite different.
Foam can be appealing if you want something that is easy to work into a daily grooming routine and dries relatively quickly.
Liquid solution uses a dropper to measure and distribute the product directly across the treatment area and can offer excellent value, particularly in larger multi-month packages.
Neither format is automatically right for everyone.
We've created a separate Foam vs. Liquid Minoxidil Guide to help you compare the two.
How Long Does Minoxidil Take to Work?
Think in months rather than days or weeks.
Timing varies by product and individual. For example, Rogaine Canada says regrowth with its Men's 5% Foam can occur as early as eight weeks, although some people may require up to four months to begin noticing results.
Consistency matters.
Using more minoxidil than directed doesn't mean faster hair growth and may increase the likelihood of unwanted effects.
How Do You Apply Minoxidil?
Exact instructions depend upon the product.
In general, topical minoxidil is applied directly to the areas of the scalp identified in the product directions rather than simply coating the hair.
Depending on the formulation, the measured dose may be expressed as a volume of liquid or an amount of foam.
Always:
-
Read the complete product label before first use.
-
Follow the dosage and frequency stated for your specific product.
-
Apply to the scalp as directed.
-
Wash your hands thoroughly after application.
-
Allow the product to dry as directed.
-
Don't use extra product in an attempt to accelerate results.

Is Minoxidil Right for Everyone?
No.
OTC minoxidil labels contain important restrictions and warnings. Depending on the product, you may be advised not to use it if your hair loss is sudden or patchy, you don't know the cause of your hair loss, your scalp is red, infected, irritated or painful, or you are under 18.
There are additional warnings and circumstances in which you should speak with a healthcare professional.
That's one reason we strongly recommend reading the complete package labeling rather than treating minoxidil as a generic cosmetic hair product.
Choosing a Minoxidil Product
Start with four questions:
1. Who is the product intended for?
Choose a product labeled appropriately for you.
2. What concentration does the label specify?
We carry different minoxidil strengths depending on the product.
3. Do you prefer foam or liquid?
This often comes down to application preference, routine and value.
4. Which brand do you prefer?
We offer established options including Kirkland Signature, Rogaine and Member's Mark.
Consistency Beats Complexity
Minoxidil doesn't need to become the focus of your day.
Choose an appropriate product, read its directions carefully and build its correct application schedule into a routine you can follow consistently.
Then give it time.
