Hair Loss Changes After Using Minoxidil: A Patient's Journey - Dermatology

Starting to address the changes in hair loss after discontinuing medication?


Hello, doctor.
I have been worried about my thinning hair since my university days.
(I tend to worry a lot when I notice my hair looks sparse.) Since college, I have developed a habit of using Japanese hair growth products, including brands like Shiseido and Kao.
At one point, I thought my condition was improving.
Last year, I couldn't convince myself that my thinning hair was not an issue, so I switched to another Japanese brand, Daiichi Sankyo, which is classified as a Class III pharmaceutical hair growth stimulant.
After using it for over six months, I still didn't notice any significant improvement, so in February of this year, I started using Rogaine foam.

Since I have long hair, I can easily collect the strands that get caught in the drain while washing my hair.
Over the past year, I've noticed that on good days, I lose about 30 strands, while on bad days, it can be 40 to 50 strands.
Of course, after blow-drying, I lose some more.
When I started using Rogaine, I was initially concerned about increased shedding, but I didn't observe any significant changes, so I continued using it.
Now, after six months, I noticed that starting in early to mid-August, the amount of hair caught in the drain during washing has increased to 40-50 strands consistently, and this week, it has escalated to 60-70 strands for several consecutive days, not including the hair lost after blow-drying.

In the past couple of months, I have observed that about one-third of the hair I lose is fine or short.
Recently, I've also noticed that even thicker strands are falling out more frequently.
Doctor, could this be a result of Rogaine prompting my hair to shed after six months of use? (I believe my lifestyle and routine have not changed over the past few years.)

It may take six months of application to see initial results.

The journey of dealing with hair loss can be quite complex, especially when using treatments like Minoxidil. Your experience reflects a common concern among individuals who are trying to manage hair thinning or loss. Let's break down the situation and provide some insights into what you might be experiencing.

Minoxidil, a topical treatment commonly used for androgenetic alopecia (male or female pattern baldness), works by stimulating hair follicles and promoting hair regrowth. However, it is not uncommon for users to experience an initial shedding phase, often referred to as "shedding" or "telogen effluvium," shortly after starting the treatment. This can be alarming, but it is generally considered a normal part of the hair growth cycle as the treatment encourages older, weaker hairs to fall out to make way for new, healthier growth.

In your case, it seems that after six months of using Minoxidil, you have noticed an increase in the number of hairs falling out during washing and styling. This could indeed be related to the treatment. The shedding phase can vary in duration and intensity from person to person. For some, it may last a few weeks, while for others, it could extend over several months. The fact that you are observing a mix of fine and coarse hairs falling out could indicate that the treatment is working to some extent, as Minoxidil can stimulate the growth of new hair that may initially be finer and softer.

It's also important to consider other factors that could influence hair loss. Stress, hormonal changes, diet, and overall health can all play significant roles in hair health. You mentioned that your lifestyle has not changed significantly, but even subtle shifts in stress levels or health can impact hair growth and loss. Additionally, if you have been using various hair products or treatments over the years, they could also contribute to the condition of your hair and scalp.

If you are concerned about the amount of hair you are losing, it may be beneficial to consult with a dermatologist or a trichologist who specializes in hair and scalp health. They can provide a thorough examination and may recommend further tests to rule out any underlying conditions that could be contributing to your hair loss. They can also help you determine whether to continue with Minoxidil or consider alternative treatments, such as Finasteride, which is an oral medication that can help reduce hair loss by blocking the hormone responsible for hair thinning.

In summary, while it is possible that the increase in hair shedding you are experiencing is a normal response to Minoxidil, it is crucial to monitor the situation closely. If the shedding continues or worsens, seeking professional advice would be a prudent step. Remember, hair regrowth treatments can take time, and patience is often required to see significant results.
