About 1 in 3 men concerned about hair loss have experience with AGA treatment

When men concerned about hair loss were asked about their experience with AGA treatment, 18.0% said they are "currently undergoing treatment," and 14.0% said they "have undergone treatment in the past," for a total of 32.0% who have experience with AGA treatment.

Experience with AGA treatment

Among men concerned about hair loss, approximately 1 in 3 have experience with AGA treatment.

On the other hand, a majority have no treatment experience, suggesting that many men who are concerned about their hair have not yet started treatment.

Furthermore, when those who have undergone AGA treatment were asked about the duration of treatment, the most common answer was between 3 months and less than 1 year.

Duration of AGA treatment

It appears that many people continue treatment for a certain period while monitoring progress, as AGA treatment requires ongoing commitment.

Noticing changes from AGA treatment: Most common period is "3 months to less than 1 year"

When those who have undergone AGA treatment were asked if they notice any changes, the most common response was "I notice some changes" at 60.7%.

Noticing changes from treatment

It appears that many people notice changes gradually, not just clear-cut results, with AGA treatment.

Furthermore, when those who noticed changes were asked how long it took, the most common answer was "3 months to less than 1 year."

Time when changes from treatment were noticed

While the time to notice changes varies by individual, it appears that many people gradually notice changes while continuing treatment for a certain period.

Looking at the percentage of people who noticed changes by treatment duration, 0.0% of those with a treatment duration of less than 3 months reported noticing changes.

In contrast, 74.1% of those with a duration of 3 months to less than 1 year, and 75.0% of those with a duration of 1 year to less than 3 years, reported noticing changes.

[By treatment duration] Percentage who noticed effects

Those who continued for 3 years or more had an even higher percentage of noticing changes, but this should be considered a reference value due to the small sample size.

This survey suggests that it is important not to judge AGA treatment in the short term but to continue for a certain period while monitoring progress.

In particular, those who noticed changes tended to do so after at least 3 months from the start of treatment.

Countermeasures for greasy hair and scalp during the rainy season

During the rainy season, hair can become greasy and scalp stickiness can become more noticeable due to humidity, sweat, and sebum.

If you are concerned about greasy hair or scalp, consider the following measures:

・Gently wash the scalp to remove sebum and sweat

・Thoroughly dry the scalp with a hairdryer after washing

・Avoid using too much styling product

・Choose a hairstyle with good ventilation

・Wash your hair promptly on days you sweat

・If scalp greasiness or odor persists, review your hair care products

On the other hand, if you are concerned not only about greasy hair but also about increased hair loss or progressive thinning, it may be related to AGA. If self-care does not improve the condition or if you are concerned about progressive thinning, consulting a doctor is one option.
