Minoxidil is a popular hair loss treatment that can help promote hair growth and prevent further shedding. However, one common side effect of using minoxidil is an itchy scalp. This can be frustrating and uncomfortable, leading some people to discontinue treatment. Luckily, there are ways to manage and reduce minoxidil-induced scalp itching. In this article, we’ll explore why minoxidil causes itchiness, provide tips and tricks for dealing with it, and answer frequently asked questions.

Key takeaways:

Minoxidil can cause scalp itching in up to 13.8% of users due to ingredients like propylene glycol or increased dryness.
Switching to minoxidil foam, using the correct dosage, moisturizing, and trying anti-dandruff shampoos can help reduce itching.
Persistent, severe itching may require medical treatment with antihistamines or steroid creams.
An itchy scalp doesn’t necessarily mean minoxidil is working, but some regrowth can be expected after 2-4 months of consistent use.

What Is Minoxidil And Does It Cause An Itchy Scalp?

Minoxidil Scalp Itching

Minoxidil is a topical medication used to treat androgenetic alopecia (male and female pattern baldness) and other types of hair loss. It comes in liquid and foam formulations and is applied directly to the scalp twice daily.

Minoxidil is a topical medication used to treat hair loss, commonly known by the brand name Rogaine. It works as a vasodilator, meaning it widens blood vessels and increases blood flow to the scalp, which can stimulate hair growth.

Research shows that up to 13.8% of people using minoxidil experience mild scalp itching or irritation. For those with other hair loss conditions, the incidence can be as high as 60%.

The results indicate that itchy scalp is a very common side effect experienced by many users of minoxidil. There are a few key reasons why minoxidil can cause an itchy scalp:

  1. The increased blood flow and sensitivity in the scalp from the vasodilating effects of minoxidil can lead to irritation and itchiness.
  1. Many minoxidil formulations contain ingredients like propylene glycol and alcohol that can be drying and irritate the scalp skin, causing itchiness.
  1. Minoxidil can exacerbate existing conditions like seborrheic dermatitis (dandruff), leading to an itchy, flaky scalp.
  1. In some cases, people may have an actual allergic reaction or sensitivity to the minoxidil itself, resulting in itching and other inflammatory symptoms.

The results provide several tips for managing minoxidil-related scalp itching, such as switching to a minoxidil foam product, using medicated shampoos, applying moisturizers, and potentially reducing the frequency of use or trying a lower concentration.

Why Does Minoxidil Cause An Itchy Scalp? 

There are a few potential reasons why minoxidil may cause an itchy scalp:

1. Propylene glycol – Many minoxidil solutions contain this ingredient, which can irritate the scalp and cause itchiness in some people.

2. Increased dryness – Minoxidil can dry out the scalp, leading to itchiness, flaking, and dandruff.

3. Allergic reaction – In rare cases, some individuals may have an allergic reaction to minoxidil itself, resulting in scalp irritation and itching.

How To Stop Minoxidil Itching?

If you’re experiencing an itchy scalp from minoxidil, try these tips:

– Use minoxidil foam instead of liquid, as it doesn’t contain propylene glycol

– Only use the recommended dosage (typically 1ml twice daily)

– Moisturize your scalp with a gentle, fragrance-free cream or oil

– Use an anti-dandruff shampoo with active ingredients like ketoconazole or zinc pyrithione

– Take an over-the-counter oral antihistamine to reduce itching and inflammation

– See your dermatologist about a prescription steroid solution or cream if itching is severe

Is Rogaine Supposed To Make Your Head Itch?

Rogaine is a brand name for minoxidil. The liquid Rogaine formulation contains propylene glycol, so it is more likely to cause scalp itching and irritation compared to the foam version, which is propylene glycol-free.

Side Effects Of Too Much Minoxidil

Using more minoxidil than directed can increase the risk of side effects[Source: NCBI]like:

– Severe scalp itching and pain

– Excessive hair growth on the face and body (hirsutism) 

– Headaches

– Worsening of seborrheic dermatitis

It’s important to follow the dosage instructions carefully to minimize these effects.

Does An Itchy Scalp Mean My Hair Is Growing?

Based on the information I researched in the sources, an itchy scalp does not necessarily mean that hair is growing. In fact, itching is more commonly associated with scalp conditions that can impede hair growth rather than encourage it.

Itching can be a sign of underlying issues like skin conditions (e.g., dandruff, eczema, psoriasis), stress, poor nutrition, or reactions to hair products, which can potentially lead to hair loss if left untreated. Therefore, while some may associate scalp itching with new hair growth, it is important to address the root causes of itching to maintain scalp health and support healthy hair growth.

How To Treat Dry Scalp From Minoxidil?

Minoxidil can strip the scalp of its natural oils, leading to dryness, flaking, and itchiness. To combat this:

– Use a gentle, fragrance-free moisturizing shampoo and conditioner

– Apply a leave-in scalp treatment or hair mask weekly 

– Avoid harsh styling products and heat tools

– Stay hydrated by drinking plenty of water

How Can You Tell If Minoxidil Is Working?

It can take 2-4 months of consistent minoxidil use to see visible results like:

– Decreased shedding

– Thicker, more dense hair growth

– Regrowth of miniaturized hairs

Be patient and stick with your treatment routine. If no regrowth occurs after 6 months, speak to your dermatologist about adjusting your treatment plan.

My Tips For Dealing With Itching From Minoxidil

I’ve worked with many patients who experience scalp irritation and itching when using minoxidil (the active ingredient in Rogaine) to treat hair loss. It’s a very common side effect, but the good news is there are several strategies we can use to manage it effectively.

The first thing I tell my patients is that some degree of itchiness is normal, especially when first starting minoxidil treatment. Your scalp is adjusting to the increased blood flow and presence of the medication, and this can cause temporary irritation. With consistent use over time, this tends to subside as the scalp acclimates.

However, if the itching is severe or persistent, there may be a few underlying factors at play. Minoxidil contains propylene glycol[Source: CDC], which can be drying and irritating for some people. Switching to the foam formulation, which lacks this ingredient, may provide relief.

Another potential culprit is seborrheic dermatitis – essentially dandruff. The increased oil production stimulated by minoxidil can exacerbate this condition, leading to an itchy, flaky scalp. Using a medicated shampoo containing ingredients like ketoconazole or zinc pyrithione can help calm the inflammation.

I also recommend that my patients try reducing the frequency of minoxidil application. Many people use it twice daily, but cutting back to once a day can sometimes minimize the irritation. It may take a bit longer to see results, but it can be worth it for improved comfort.

Keeping the scalp well-moisturized is crucial as well. I suggest using a lightweight, non-greasy serum or essential oil a few times per week to soothe dryness and itchiness. Gently massaging it into the scalp can also help increase blood flow and reduce inflammation.

If the itching is severe or accompanied by redness, swelling, or other concerning symptoms, it’s important to see a dermatologist right away. You may need a topical steroid or other medication to get the inflammation under control. Trying to power through extreme discomfort is not advisable.

The key is to be patient, experiment with different techniques, and work closely with your dermatologist. Minoxidil is an effective treatment, and the itchiness can be managed. With the right approach, you can get hair growth benefits without scalp irritation.

Sum Up

While an itchy scalp is a common side effect of minoxidil, there are ways to reduce and manage the discomfort. Be diligent about moisturizing, use the proper dosage and form, and incorporate medicated shampoos into your routine. If itching is severe, seek medical advice, as oral medications or prescription treatments may be needed. With some troubleshooting, you can continue using this effective hair-loss treatment while keeping your scalp calm.


Q1. How long does minoxidil itching last?

For most people, the itchiness starts within a few weeks of beginning treatment and may persist until the scalp adjusts. However, some experience chronic, recurring itchiness.

Q2. Is itching a sign minoxidil is working?

No, itching is simply a side effect and not an indicator of hair regrowth efficacy.

Q3. Can I use hydrocortisone cream for minoxidil itching?

Over-the-counter hydrocortisone can provide temporary relief, but stronger prescription steroid creams may be needed for severe, persistent itching.

Q4.Will my hair loss get worse if I stop minoxidil due to itching?

Unfortunately, any new regrowth achieved with minoxidil is likely to shed once you discontinue use. Consult your doctor before stopping treatment.

Q5.What ingredients cause minoxidil itching?

Propylene glycol is the most common irritant, but sensitivities can also occur with minoxidil itself, alcohol denaturants, or inactive ingredients.
