Does minoxidil spray for hair growth work?

Most people worried about hair loss either use minoxidil or foam to fight hair loss. It’s scientifically proven to be effective, and safe for both men and women to use.

The topical solution can be applied with a minoxidil spray, which is convenient, and spreads out the solution much better than a simple dropper would.

But is a minoxidil spray for hair growth effective to slow down hair loss, and even to regrow lost hair? To answer the question briefly already, yes it is. Let me explain why.




Is minoxidil spray for hair growth effective?

Yes, minoxidil spray for hair growth is indeed effective. It basically works the same as topical minoxidil does, with the added benefit of not having to apply the solution with a dropper or hands. This means that less of the product gets stuck to the hair.

Due to the spray, the mist gets evenly distributed across the top of the head, speedily drying onto the skin rather than on the hair, which would reduce its efficiency.

Does minoxidil spray regrow hair?

Yes, minoxidil spray does regrow hair. Although it should be noted that regrowing hair is much harder than slowing down, or halting hair loss. That’s also why you should start using minoxidil as soon as you notice you’re losing hair.

Then there’s also the chance of not responding to a topical treatment, in which case an oral minoxidil treatment can offer solace in many instances. Ingesting this minoxidil orally is done by taking in minoxidil tablets/pills. But be warned. There will be more systematic absorption when taking the medication orally since it enters the bloodstream, which can increase aftereffects.




Minoxidil hair spray for men and women

Minoxidil hair spray exists for both men and women.

The main difference is that the sprays that exist for men are typically stronger, which means they consist of a higher minoxidil % than the sprays that are tailored to women do.

Most minoxidil spray bottles for men will be between 5%-10%, while most women sprays will be between 2% and 5%. The FDA guidelines state that women shouldn’t go above 5% minoxidil to minimize health risks and to limit the risk of contracting negative side effects.

The key advantage is that stronger products are typically more effective at slowing down hair loss. However, the main downside is that higher strength products tend to induce more severe side effects, and at an increased rate. Still, negative consequences are not that common, and are mostly not intense at all.

Minoxidil spray for male individuals

Essential to remember is that if the minoxidil solution isn’t more than 5%, then the FDA considers it safe for female use as well.

This means that a lot of topical minoxidil that gets promoted specifically for men can also be used by women.

The following list of sprays are specifically tailored to men:

  • Regenepure, Precision Minoxidil Spray for Men, 5% Minoxidil Hair Growth Treatment

  • BosleyMD Men’s Extra Strength Minoxidil 5% Topical spray

  • Tomum 5% Minoxidil Hair Growth Spray For Men and Women

  • ELEVATE 5% Minoxidil Hair Growth Spray – Extra Strength for men and women

  • Maxogain 5 Men’s Extra Strength 5% topical 4in1 Advanced Hair Regrowth Formula

  • Minoxil forte Anti 5 % Hair Loss Regrowth Spray for Men

  • Hair and beard growth spray 5% minoxidil spray

  • ALOPEXY Minoxidil 5% Extra Strength Men

  • Minoxidil 5% Extra Strength Men Woman Spray Serum Hair Regrowth Solution

  • REGROWE hair regrowth formula minoxidil 5%

  • for MEN Minoxidil Topical Solution USP 5% for Hair Growth alcohol free

  • Tugain 5% solution for Hair Regrowth

  • MINTOP Minoxidil Topical Solution USP 5%

minoxidil spray for female individuals

Although it should be stated that men can use women sprays as well, seeing as they’re simply less strong versions of the products that men usually use.

As long as it’s a minoxidil based product, all men can use the products of women since the topical minoxidil solutions designed for women are never stronger than those for men.

These hair sprays are made precisely for women:

  • Regenepure, Precision Minoxidil Spray for Women, 5% Minoxidil Hair Growth Treatment

  • Precision Minoxidil 5% Spray for Female Hair Loss Treatment

  • ELEVATE 5% Minoxidil Hair Growth Spray – Extra Strength for men and women

  • Tomum 5% Minoxidil Hair Growth Spray For Men and Women

  • Minoxidil 5% Extra Strength Men Woman Spray Serum Hair Regrowth Solution


  • BosleyMD Hair Regrowth Treatment Regular 2% Strength Women

  • Qilib 2% Minoxidil Regrowth Revitalization Hair System for Women

  • ScalpMED 2% Minoxidil for Women – Vitadil-2A Hair Regrowth Treatment

  • Keranique Hair Regrowth Treatment for Women 2% Minoxidil

  • Hair and beard growth spray 5% minoxidil spray

Which minoxidil spray is best?

Which minoxidil spray is best is a very tough question to answer, seeing as there’s not one definitive answer to this broad and vague question.

Best for what? To limit hair loss and regrow hair? To produce the least amount of negative side effects? The cheapest?

The best spray would depend on what you’re looking for. But what I can say is that the most effective sprays to fight hair loss will most likely be the ones that are the highest in strength. Although at the cost of probably inducing a larger amount, and stronger negative consequences.




How long does minoxidil spray take to work?

Like other forms of minoxidil, a minoxidil spray starts working immediately.

However, it typically takes a while before most of us see the effects of their minoxidil treatment. That’s why we often think that minoxidil doesn’t start working immediately, yet it does.

Usually, the effects become detectable between 4–8 weeks after initializing treatment. But for some, minoxidil simply doesn’t work, or is not as efficient as it is for others. Each individual’s DNA is different, and this also means that some might be hyperresponders, while others don’t respond to the drug at all.


how to apply minoxidil spray?

For the best results, the minoxidil should reach the scalp instead of just the hairs. This remains true for both foam and liquid.

That’s why we should start off by separating the hairs in sections to allow the spray to reach the skin instead of just the hair follicles.

This is how to apply minoxidil spray:

  1. Separate the hair in multiple different sections so that the scalp becomes visible.
  2. Make sure your hair is dry before applying the minoxidil spray since water dilutes the product, making it less effective.
  3. Aim the minoxidil spray directly at the scalp.
  4. Spray the minoxidil spray on the scalp in the different sections until all parts of the scalp are covered.

After applying the minoxidil, all you need to do is let the solution dry on the skin. Since the minoxidil mist is applied scattered, it gets absorbed much easier and quicker by the skin than a topical solution, or even foam.

As a result, there will be less overspill as well.


Minoxidil spray side effects

What are the side effects of minoxidil spray?

The possible side effects of minoxidil spray are the same as minoxidil foam, solution, and oral minoxidil.

But the side effects are usually less severe, and a less common occurrence compared to oral minoxidil since there’s much less systematic absorption since it gets applied topically instead of circulation through the entire body and bloodstream.

However, since you’re spraying a liquid version, the side effects are frequently more serious and bothering in nature than the foam is. The reason for this is that the liquid contains propylene glycol as a solvent that dries out the skin.

Less common and non-dangerous side effects

  • Scalp itching[1]
  • Hair shedding because the telogen phase of hair growth is shortened
  • Skin irritation: discomfort, burning sensation and/or erythema
  • Scaly changes of the applied area: irritation or exacerbation of seborrheic dermatitis
  • Isolated pruritus
  • Generalized or localized hypertrichosis: This can occur with both the topical and oral minoxidil. It is however more common with the oral form and 5% than the 2% minoxidil because there is more systematic absorption. Research has suggested that hypertrichosis is related to minoxidil’s prolongation of the anagen phase
  • Allergic contact dermatitis: Pruritus, eczematous skin reaction and erythema. Propylene glycol and minoxidil are two major allergens in allergic contact dermatitis. There is also minoxidil foam that lacks propylene glycol, which can be a viable option if an allergic reaction happens[2]
  • Minoxidil may make your skin sensitive to sunlight. Avoid unneeded or prolonged exposure to sunlight. Make sure to wear protective sunscreen, glasses, and clothing depending on where you applied the topical minoxidil solution.
  • Skin flushing

Rare side effects that are a sign of too much minoxidil being absorbed in the body (too much systematic absorption)

Remember to always immediately go to an emergency care center or to call 911 in case of severe side effect. In other words, seek immediate professional help if any of the following symptoms arise:

  • Chest pain
  • Fast heartbeat
  • Irregular heartbeat
  • Difficulty breathing (especially when lying down)
  • swelling of the face, ankles, hands, or stomach[3]
  • Rapid weight gain
  • Tingling feeling or numbness of the face, hands and/or feet
  • Headache
  • lightheadedness
  • Blurry vision
  • Feeling dizzy
  • Fainting
  • Severe skin irritation



Is it better to spray minoxidil?

Minoxidil spray is simply a topical solution that’s being sprayed on the scalp like a mist of tiny liquid droplets.

As some of you might already know, the topical solution and oral medication tend to produce more annoying side effects such as flaking, redness of the skin, and itching than the topical foam does.

As such, a topical spray can limit the side effects of the minoxidil liquid because it’s better spread out instead of localized. Still, the foam will probably bring forth less negative side effects than the solution does since it dries out the skin to a much lesser degree.




Is Minoxidil foam or spray better?

Again, that depends on what your definition of being ‘better’ is.

Minoxidil foam and liquid are more or less equally efficacious with regard to slow down or halt hair loss, and even to regrow lost hair.

However, they’re not the same if we factor in the amount of negative side effects they typically generate.

The topical spray and solution are comprised of liquid, which includes propylene glycol as a solvent. This solvent typically dries out the skin, which will lead to an increased rate of annoying side effects such as redness, and flaking of the skin.

The foam variant typically doesn’t have propylene glycol as an active ingredient, which means it dries the skin out less. Thus less, and fewer annoying consequences will most likely be caused when using foam over liquid.



A minoxidil spray does regrow hair, or at the very least aids to slow down progressive hair loss.

A spray can help to produce less side effects because the liquid is more spread out compared to applying the minoxidil with a droplet. Still, a foam would probably cause fewer detrimental effects than the liquid since they dry out the skin to a lesser degree. This is due to the usual absence of the solvent propylene glycol that’s present in the liquid version.

Nevertheless, the liquid and foam work just as good to fight hair loss. But if you have a history of allergies and/or a sensitive skin, then I would suggest using a minoxidil foam over liquid.
