Minoxidil Withdrawal and Why It’s Important to Continue Minoxidil

Minoxidil is one of the most effective and widely-used treatments for hair loss, especially for those dealing with conditions such as androgenetic alopecia. However, minoxidil is not a quick fix, and long-term commitment is necessary to sustain its benefits. In this blog, we’ll explore why regular, consistent use of minoxidil is vital, what happens when you stop using it, and how to reduce hair loss if withdrawal becomes necessary.


Part 1: The Importance of Compliance with Minoxidil


As a prescribing trichologist, I regularly see patients who expect minoxidil to deliver results within weeks. While minoxidil can indeed work wonders for hair loss, it’s important to understand that it is not a cure, but a long-term management tool. To maintain the results achieved with minoxidil, ongoing and consistent use is crucial.


How Minoxidil Works

Minoxidil is a vasodilator, originally developed to treat high blood pressure. When applied topically, it dilates blood vessels around hair follicles, improving blood flow and encouraging the delivery of essential nutrients and oxygen to the follicles. This supports the follicles’ health, extends the growth phase (anagen phase) of the hair cycle, and shortens the resting phase (telogen phase), allowing more hairs to stay in the growing phase for longer.


Studies show that minoxidil can reduce hair shedding and promote regrowth in approximately 60% of users. However, it can take 4-6 months of continuous use before visible results appear, and these results can only be sustained with regular application.


Why Consistency Matters

Consistency is the key to success with minoxidil. Missing applications or stopping treatment can result in rapid hair loss, often worse than before treatment began. This occurs because minoxidil doesn’t address the root cause of hair loss, such as genetics or hormonal factors; instead, it only manages the symptoms. When treatment is stopped, the hair follicles lose the support minoxidil provided, and the underlying cause of hair loss takes over.


One common challenge patients face is the "minoxidil shed." This refers to an initial increase in hair shedding, typically seen in the first 2-6 weeks of use. This is a normal part of the treatment process, as older hairs are pushed out to make way for new growth. Although this shedding can be concerning, it’s actually a positive sign that the treatment is working. Stopping minoxidil during this phase can lead to even more significant hair loss and reduced effectiveness in the future.


Regular use ensures that your hair remains in the growth phase longer, and this consistency is essential for maintaining healthy, dense hair. Skipping applications will diminish the treatment's efficacy, leading to thinner hair and a loss of the progress you’ve made.


Evidence Supporting Minoxidil

Numerous studies have demonstrated the effectiveness of minoxidil for treating androgenetic alopecia. For example, research published in Dermatologic Therapy found that both 2% and 5% minoxidil solutions significantly improved hair regrowth, with the 5% solution offering faster results. However, these benefits only last as long as treatment is continued. Once stopped, hair returns to its pre-treatment state, which underscores the importance of consistent use.


Part 2: What Happens When You Stop Using Minoxidil?

Deciding to stop minoxidil can lead to the reversal of its positive effects. When you stop applying minoxidil, the hair follicles that benefited from the treatment lose their support and begin to shrink, which eventually results in hair thinning and shedding.


What to Expect if You Stop

Hair loss after discontinuing minoxidil does not happen immediately but follows a predictable timeline. Understanding this process can help set expectations if you plan to stop the treatment:


  • First Month: During this time, the hair remains relatively stable, as minoxidil’s effects take time to wear off.

  • Month 2-3: Hair shedding becomes more noticeable as follicles begin to revert to their natural hair cycle. Hairs that were being held in the growth phase by minoxidil start to enter the resting phase, leading to increased shedding.

  • Month 4-6: By this point, most of the hair that had been maintained by minoxidil will have shed. Thinning becomes more visible, and scalp coverage decreases.

  • Beyond 6 Months: Hair will likely return to its pre-treatment condition, with any gains achieved during minoxidil use lost.


Here is a timeline summarising what you can expect after discontinuing minoxidil:

Time After Stopping Minoxidil

Expected Hair Condition

0-1 Month

Minimal to no change

2-3 Months

Increased shedding and thinning

4-6 Months

Significant thinning and hair loss

6+ Months

Hair returns to pre-treatment state

How to Minimise Hair Loss After Withdrawal

If you decide to stop using minoxidil, there are strategies to minimise the impact and help retain as much hair as possible:


  1. Gradual Tapering: Instead of stopping minoxidil suddenly, gradually reduce the frequency of applications over time. This can help your scalp and hair follicles adjust to the absence of the treatment and reduce the severity of post-minoxidil shedding.

  2. Alternative Treatments: If you plan to stop minoxidil, consider transitioning to alternative treatments such as low-level laser therapy (LLLT), microneedling, or platelet-rich plasma (PRP) therapy. These options can help maintain follicle health and support regrowth without the dependency associated with minoxidil.

  3. AnteAGE MD® Hair Solution: Another alternative to consider is the AnteAGE MD® Hair Solution. This science-based treatment promotes follicle health and supports hair growth using growth factors and cytokines, without the need for continuous application like minoxidil.

  4. Science-Based Hair Supplement - TrichoRx24: Using a supplement like TrichoRx24 can support hair health from within, providing essential nutrients specifically formulated to promote strong, healthy hair. TrichoRx24 is a science-based formula that helps improve hair vitality and strength, even after discontinuing minoxidil. This supplement ensures that your follicles remain nourished and supported, reducing the chances of rapid hair loss post-minoxidil.
