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

The issue of changes in hair loss after starting to use topical minoxidil?

Hello, doctor.
I have been worried about my thinning hair since my university days.
(I tend to be the type of person who gets anxious when I notice any thinning.) Since college, I have developed a habit of using Japanese hair growth products, including brands like Shiseido and Kao.
During that time, I thought my condition was improving.
Last year, I couldn't convince myself that the thinning was not an issue, so I switched to another Japanese brand, Daiichi Sankyo's third-class pharmaceutical-grade hair growth stimulant, for over six months, but I still felt there was no improvement.
Therefore, in February of this year, I started using Rogaine foam.
Since I have long hair, I can easily collect the hair that gets caught in the drain while washing.
Over the past year, I have noticed that on good days, I lose around 30 strands of hair, while on bad days, it can be 40 to 50 strands.
Of course, after blow-drying, I lose some more.
Initially, I was concerned about experiencing increased shedding when I started using Rogaine, but I didn't particularly observe that, so I continued using it.
Now, after six months, starting from early to mid-August this year, I have noticed an increase in the amount of hair caught in the drain during washing, consistently around 40 to 50 strands, and this week it has escalated to 60 to 70 strands for several consecutive days, not including the hair lost while 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 have also noticed that even thicker strands of hair are falling out more frequently.
Doctor, could this be the 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.)

The journey of hair loss treatment, particularly with Minoxidil, can be complex and often varies from person to person. Your experience reflects a common concern among individuals using Minoxidil, especially regarding the initial shedding phase and the overall effectiveness of the treatment.

Minoxidil, a topical solution commonly used for treating androgenetic alopecia (male or female pattern baldness), works by stimulating hair follicles and increasing blood flow to the scalp. It is important to note that when starting Minoxidil, many users experience an initial shedding phase, often referred to as "shedding." This can be alarming, as it may seem counterproductive to the goal of regrowing hair. However, this shedding is typically a sign that the medication is working; it indicates that the old, weaker hairs are falling out to make way for new, healthier hair growth.

In your case, it seems that after six months of using Minoxidil, you have begun to notice an increase in the number of hairs falling out during washing. This could indeed be related to the treatment. The shedding phase can occur at different times for different individuals, and it is not uncommon for it to start several months after beginning treatment. The increase in hair loss you are observing, particularly with finer or shorter hairs, may suggest that the Minoxidil is stimulating the hair follicles to enter a new growth cycle, which can temporarily result in increased shedding.

It's also worth noting that hair loss can be influenced by various factors, including stress, hormonal changes, diet, and overall health. If your lifestyle and routine have remained consistent, it may be beneficial to evaluate other factors that could contribute to your hair loss. For example, stress from academic or work-related pressures can exacerbate hair loss conditions. Additionally, nutritional deficiencies or changes in your health status can also play a role.

If you are concerned about the amount of hair loss you are experiencing, it may be beneficial to consult with a dermatologist or a healthcare provider specializing in hair loss. They can assess your scalp and hair health, review your treatment regimen, and determine if any adjustments are necessary. They may also recommend additional treatments, such as Finasteride, which can be used in conjunction with Minoxidil for enhanced results, especially in cases of androgenetic alopecia.

In summary, while the increase in hair shedding you are experiencing after using Minoxidil for six months can be concerning, it may be a normal part of the hair growth cycle as the medication takes effect. Monitoring your hair loss and consulting with a healthcare professional can provide you with the guidance and reassurance you need as you navigate this treatment journey. Remember, patience is key in hair restoration treatments, as results can take several months to become noticeable.
