15 Minoxidil myths and facts: Separating fiction from reality

Minoxidil, a popular over-the-counter medication for hair loss, has been a subject of myths and misconceptions over the years.

While it’s a proven and effective treatment for many, there are still a lot of misunderstandings about how it works and what it can or cannot do. But today, I’m going to clear up the confusion by exploring some common minoxidil myths and presenting the scientific facts.

Myth #1: Minoxidil can reverse baldness completely

Fact: Minoxidil is excellent at promoting hair regrowth, but it doesn’t guarantee a full reversal of baldness.

Its effectiveness varies from person to person and largely depends on factors such as the extent of preexisting hair loss and the duration of baldness before starting treatment. Minoxidil is typically most potent for those with recent hair loss or thinning.

Myth #2: Minoxidil works for everyone

Fact: Unfortunately, minoxidil doesn’t work for everyone. Success rates vary, and factors like genetics, age, and the cause of hair loss play a role in determining how well it works.

It is more useful in individuals with androgenetic alopecia, also known as male or female pattern baldness.

Myth #3: Minoxidil causes hair to grow everywhere

Fact: Minoxidil is designed to be applied to specific areas of the scalp affected by hair loss. It doesn’t make hair grow in unwanted places like your face or arms. The product’s effects are localized to the areas where it’s applied.

However, when overdosing or taking very large doses, unwanted hair growth can still occur, albeit very rarely. This risk is enlarged when using oral minoxidil since there’s more systematic absorption involved when taking the product orally.

Myth #4: Once you start minoxidil, you can never stop

Fact: Minoxidil is a long-term commitment, but you can stop using it whenever you choose to.

Nevertheless, it’s important to note that discontinuing use may lead to a gradual return of hair loss. It’s a maintenance treatment, and its benefits generally cease to exist gradually over time when you stop using it.

Myth #5: More minoxidil equals faster results

Fact: Using more minoxidil than recommended won’t speed up hair growth and may increase the risk of side effects.

Stick to the recommended dosage on the product label. Excess application doesn’t equate to faster or better results. Yet, a higher strength product may yield better results.

Myth #6: Minoxidil is a cure for hair loss

Fact: Minoxidil is a treatment, not a cure. It manages hair loss by promoting hair regrowth and slowing down the hair loss process.

It doesn’t address the root causes of hair loss, such as genetics or hormonal imbalances.

Myth #7: Minoxidil works overnight

Fact: Patience is key when using minoxidil. It can take several months before you notice visible results.

New hair growth is a gradual process, and you may experience increased shedding initially before the regrowth becomes noticeable.

Myth #8: Minoxidil is only for men

Fact: Minoxidil is effective for both men and women.

There are specific formulations designed for each gender. Women should use a lower-strength minoxidil solution (typically 2%), while men can use higher-strength solutions (5%).

Myth #9: Minoxidil works equally well for all hair types

Fact: Minoxidil is generally effective for a wide range of hair types, but it may produce different results for individuals with different textures (e.g., straight, curly, wavy).

The efficacy can vary based on factors such as the density and coarseness of your hair.

Myth #10: Minoxidil causes permanent hair growth

Fact: Minoxidil’s effects are mostly reversible. If you stop using minoxidil, the newly grown hair may gradually revert to its previous state.

This is why it’s considered a maintenance treatment, and continued use is often necessary to preserve the positive results.

However, facial hair that’s grown due to employing minoxidil is permanent if and only if the vellus hairs have transitioned to terminal hairs. This typically means using minoxidil for various months before this occurs. If you’re happy with your beard gains, then you can safely quit the product without losing your beard.

Myth #11: Minoxidil is the only solution for hair loss

Fact: While minoxidil is a proven and popular option, it’s not the only solution for hair loss.

There are other treatments available to combat hair loss rather than just minoxidil such as finasteride, hair transplant surgery, and low-level laser therapy. The best approach for combating hair loss may involve a combination of these treatments.

Myth #12: Minoxidil can regrow hair on completely bald scalps

Fact: Minoxidil is more effective at regrowing hair on areas of the scalp that still have active hair follicles.

It may be less impressive on completely bald areas where follicles have become dormant or scarred. Early intervention typically generates better outcomes.

Myth #13: Minoxidil causes immediate side effects

Fact: Minoxidil can cause side effects, but they are generally mild and not experienced by everyone.

These side effects may include scalp irritation, itching, or dryness. Severe side effects are rare, but it’s essential to follow the recommended usage guidelines to minimize any potential issues.

Myth #14: Minoxidil can reverse hair loss due to medical conditions

Fact: Minoxidil is primarily designed for androgenetic alopecia (male and female pattern baldness).

It may not be as effective for hair loss caused by medical conditions, such as alopecia areata, scarring alopecia, or underlying health issues.

Myth #15: Minoxidil is an instant fix for hair loss

Fact: Minoxidil is not a quick fix. It requires consistent, long-term use to maintain results. While some people may see improvement in a few months, it typically takes up to 6–12 months to observe significant changes in hair density and growth.

Nevertheless, minoxidil starts working immediately, but takes a while before the results become noticeable to the bare eye. That’s why you need to use it for weeks to months before you can detect any effects most of the time.
