What the package and the regulator say
We carry this product so you can look it up. We do not put it in anyone’s plan, and nothing on this page is matched to you.
From the regulator
For external use only. For use by men only. Flammable: Keep away from fire or flame. Do not use if you are a woman; your amount of hair loss is different than that shown on the side of this carton or your hair loss is on the front of the scalp. 5% minoxidil topical solution is not intended for frontal baldness or receding hairline; you have no family history of hair loss; your hair loss is sudden and/or patchy; you do not know the reason for your hair loss; you are under 18 years of age. Do not use on babies and children; your scalp is red, inflamed, infected, irritated, or painful; you use other medicines on the scalp. Ask a doctor before use if you have heart disease. When using this product: do not apply on other parts of the body; avoid contact with the eyes. In case of accidental contact, rinse eyes with large amounts of cool tap water; some people have experienced changes in hair color and/or texture; it takes time to regrow hair. Results may occur at 2 months with twice a day usage. For some men, you may need to use this product for at least 4 months before you see results; the amount of hair regrowth is different for each person. This product will not work for all men. Stop use and ask a doctor if: chest pain, rapid heartbeat, faintness, or dizziness occurs; sudden, unexplained weight gain occurs; your hands or feet swell; scalp irritation or redness occurs; unwanted facial hair growth occurs; you do not see hair regrowth in 4 months. May be harmful if used when pregnant or breast-feeding. Keep out of reach of children. If swallowed, get medical help or contact a Poison Control Center right away.

What the formula actually does
Read from the label, not the marketing
Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.
Slip and detangling
Little
Nothing here is built to reduce combing force.
Oils and butters
None
No oils or butters in the list.
Water-binding (humectants)
None found
No humectants, so nothing here pulls water into the hair.
Needs detergent to remove
No
Nothing here needs a detergent wash to remove.

How we work this out
- 2 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
- Seen at $17.99 is the price we have observed for the 2 oz. We need three stores before we call a price commonly seen.

Too few comparable prices to place it in the range; the formula itself leaves out conditioning agents up front.

The formula score measures completeness for the job: a weighted share of the systems this product type is usually built around that we find in this list. It does not rate how well the product works or its quality, and it never compares across product types.

Final decision
Should you buy it?
Depends on your hair: see who it suitsBest user
Nothing in the formula narrows this to one kind of hair.
Biggest tradeoff
No cautions in the formula.
Best alternative if not
Nothing in our library matches it closely at a lower price.
We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.
Claims check
What the brand says, and what the formula shows
Claims are quoted from the brand. We mark a claim supported, partly supported or conflicting only when the ingredient list speaks to it. Everything else stays "stated by the brand". That isn’t a criticism: most claims can’t be checked from a label.

How to read this
We look at the first 10–15 ingredients and what they do in a formula, not at the marketing. If the list doesn't speak to a claim, we don't assume.

How this page was made
- Everything above comes from our researched product record: identity, the ingredient list as printed, the brand's own claims, dated prices and review themes our researchers wrote in their own words. No part of this page is written by hand for one product.
- The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
- Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
- 3 sources consulted for this product (2 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-09-06.
- We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
- Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
