Minoxidil 5% Vs. 10%: Which is Best for Hair Growth After 48 Weeks

Minoxidil is a popular treatment, used widely by men and women with hair loss. And, while 2% and 5% are the most common dosage solutions used, the 10% solution could be a more effective way to improve hair growth results.

In this article, I’m going to compare minoxidil 10% to minoxidil 5%. There are no direct studies available on the topic, but some assumptions can be made based on the research studies that are available.

In addition, I’ll share with you an alternative treatment method to minoxidil that I (and many others) have used with much success over the past few years.

Minoxidil in the Treatment of Hair Loss

Minoxidil was developed in the 1950s, first marketed as an ulcer treatment drug, and then as a vasodilator.

As studies continued, it was found that the use of minoxidil led to unexpected hair growth.

It was believed to be a result of its vasodilating properties, enabling the capillaries in the scalp to become dilated and improving their abilities to deliver nutrients and oxygen to the hair.

As time wore on, further studies were performed to better understand minoxidil’s role in the treatment of hair loss. This eventually led to its FDA approval in 1988, and it’s been available ever since.

Is Minoxidil 5% or Minoxidil 10% More Effective?

While there are no current studies that directly compare minoxidil 10% vs minoxidil 5%, there are a few studies that can help us to better understand how minoxidil works in various doses.

One such study was performed in 2002, and it compared a 5% solution of minoxidil to a 2% solution in men with Androgenetic Alopecia (AGA).

The study consisted of 393 participants (with a total of 351 completing it), and it lasted for 48 weeks. At the beginning of the study, 157 men were assigned to the 5% minoxidil group, 158 were assigned to the 2% minoxidil group, and 78 were assigned to the placebo group.

Once baseline data (including nonvellus hair count) was collected, patients were instructed to apply 1 mL of solution (either 5%, 2%, or placebo) to their scalp twice per day (with a total daily dose of 2 mL).

After the initial visit (week 0), subjects returned every 4 weeks until week 32, and then every 8 weeks until the end of the 48-week trial. Safety and effectiveness evaluations were performed at such times.

These were the results as seen in week 48:

The results of a study on 5% minoxidil vs 2% minoxidil

The information we’re most interested is located on the right side of the table labeled Pairwise comparison P value. This tells us which of the compared solutions is superior.

In all of the investigator results (nonvellus hair count, change in scalp coverage, and benefit from treatment), you’ll notice a significant preference for 5% minoxidil over 2% minoxidil.

Remember that nonvellus hair count was measured at baseline? Here’s a look at the changes experienced by study participants over the course of the trial:

Minoxidil 5% vs Minoxidil 2% in nonvellus hair count

As easily noticed above, the 5% minoxidil solution performed better than the 2% solution during all evaluations.

This study wasn’t the only one to see such results, though. A similar study was performed in 2004, but this time with a focus on female-pattern hair loss.

As expected, the 5% minoxidil solution performed better than both the 2% solution and the placebo.

Dose Response – An Understanding of Drug Effectiveness

As shown above, dose response is a common occurrence in scientific research.

But what exactly is dose response, and what does this mean for the effectiveness of minoxidil?

In simplest terms, dose response is an expected increase in effectiveness as dosage increases.

For example, when subjects were treated with 5% minoxidil (instead of 2%), their results were better (more hair growth, increased density, etc.).

Of course, there are exceptions to the rule. However, as highlighted by the studies above, it seems that minoxidil is one drug that follows this rule.

So, while we don’t have a study that compares 10% minoxidil and 5% minoxidil directly, it’s safe to say that the 10% solution would likely show more results than the 5% solution.

Keep in mind that the results, while increased, aren’t likely to be proportional to dosage.

What I mean is that you can’t expect to see twice as much hair growth with the 10% solution than the 5% solution, because dose response doesn’t typically happen as such.

At around 10% I would expect results to plateau even if the dosage was increased. This is the law of diminishing returns, where side-effects would increase without any benefits.

Side Effects: Minoxidil 10% vs. Minoxidil 5%

With increased results, will there also be increased side effects?

The active ingredient within minoxidil, minoxidil sulfate, is fairly harmless.

It’s the non-active ingredients, such as alcohol and propylene glycol, that tend to cause the more noticeable side effects (particularly those related to skin irritation).

This means that, technically speaking, increased side effects should not be seen with increased dosage.

Is is possible? Absolutely. In fact, an increase in pruritus, local irritation, and hypertrichosis was noted in the 5% treatment group in the 2004 study referenced.

That’s why higher doses (including 10% solution) are only available through prescription and require the oversight of a doctor while in use.

What if Minoxidil 5% Isn’t Providing Desired Results?

It’s unfortunate, but sometimes even those medications that are touted to be a miracle cure by so many users don’t work for certain individuals.

But what if Minoxidil 5% is working moderately well, but you feel that results are behind others on a similar regimen?

First, I would recommend you not compare yourself to others, even those who’re taking the same treatment steps as you.

Hair loss is typically a multi-factored occurrence, and everyone will react differently to the same course of treatment.

Of course, you can always seek the help of a dermatologist, and perhaps receive a prescription for 10% minoxidil.

However, there’s a much different path I would encourage you to take, and that’s a natural one.

What I mean by this is, instead of masking the issue as minoxidil does, why not treat your hair loss at the source?

The Natural Alternative to Minoxidil Treatment

I’ve written extensively on the removal DHT from the scalp, as well as how you can make your own minoxidil at home.

And, while these methods certainly have worked for many individuals (myself included), it’s not the method I recommend.

Why?

I believe there’s a more natural approach to the reduction of DHT within the body, and that’s through alkalization of your diet.

Let’s take a closer look at what I mean

5-alpha-reductase is the enzyme responsible for converting testosterone to DHT. It also happens to thrive in acidic conditions.

Unfortunately, the modern diet is full of acidic foods, including carbonated beverages, sugary grains, and dairy. In the end, this consumption leads to an acidic pH within the bloodstream, and it enables 5-alpha-reductase to do its job.

(Learn more about the foods that inhibit 5-alpha-reductase here.)

Alkalizing your bloodstream, then, is the key when it comes to putting a stop to 5-alpha-reductase’s activities and impairing the production of DHT directly at the source.

How can you do this?

Well, the obvious answer is to add more alkaline foods into your diet. Fortunately, this is a lot easier than you may think, and even just a few small changes here and there can make a large impact.

You see, the farther you move away from processed and refined, the closer you are to alkalizing your diet and, ultimately, your bloodstream.

Now, one of the things I like to do every morning is drink a smoothie. Not only does this get me off to a healthy start, but it also sets the tone of the entire day.

Here’s a recipe that I’ve been working on over the past few years.

Every single ingredient listed has a specific purpose, and you’ll also notice that the ingredients which are included in the acidic-alkaline scale above (such as berries, almond, coconut, and banana) all fall on the alkaline side.

Conclusion

While no studies have been performed to compare minoxidil 10% and minoxidil 5%, the results from 5% vs 2% studies suggest that a higher dosage can deliver better results.

So, should you switch to minoxidil 10% if  you aren’t seeing results with the 5% solution? That’s only a question you can answer. However, I urge you to consider taking the natural route before making the decision.

  1. Hi, I’ve been using Hair 4 U minoxidil 10% from last 5 months but i didn’t find any result, moreover i have lost more hair and thinning at front side.
    Before using this 10%, I used to apply Minscalp 5% which shown me good result. After that Doctor advised to go with 10% for better results.
    Now I’m in a confusion that should i use this 10% or again 5%
    Please Suggest me.

    • Hi Laveti, that’s interesting to hear your experience. That is very confusing as well. The truth is, I don’t recommend any kind of minoxidil product, the side effects are just not worth it. You need to change your body from the inside-out first. Luckily we’ve been developing a product called GRO2 which is a natural alternative to minoxidil and has been proven to work even better. I would recommend using that instead if you’re going to continue with topical applications.

  2. I am using Rogaine 10% only a couple of days, hands swelling, legs, feet and arthritis is hurting in knees…can it be the Rogaine, rash on face..also

    • Hi Gloria,

      Yes, it’s very possible.

      I would discontinue use immediately and consult with a doctor if the symptoms worsen or don’t resolve.

      Regards,

      Steph

  3. My age is 19yrs.,is that ok to use minoxidil.cause I have very problem of hair loss and hair receding,and if yes to use it how many percentage of minoxidil I’ve used to be?

  4. Alkaline your blood cells can not be done through diet and there is no scientific proof of it being done or of benefit neither.. apart from that ridiculous statement it’s a good read.
