This time, we will introduce a case study from one of our hospital staff members.
A staff member who was a fan of our "Scalp Beauty Serum EX," which contains exosomes and was newly released in January 2026, noticed a change in hair quality and density after just one month of continuous use.

"I feel like my hair has been getting thinner lately."
"But I'm still worried about taking medication or other treatments..." I think there are many people who are struggling with this kind of problem.
Therefore, in this article, we will share real-life case studies from our clinic's hairdressers and counselors to explain the importance of maintaining a healthy scalp environment.

As a preliminary step before resorting to treatment, how much can hair density and texture change through "daily scalp care using cosmetics" without the use of medication?
Here are some of the changes our staff experienced after using the product for one month, including noticeable hair growth, increased hair density, and improved shine.
What kind of changes occurred in just one month for a staff member who already had a healthy scalp and regularly practiced scalp care? 

[Case Study] Staff Member #1: Changes in hairline density and gray hair

 
I was also surprised by the transformation when I saw the before and after pictures.
First, you can see that the density at the hairline has increased, and there is a clear increase in hair volume.
In particular, fine hairs are growing up in a bushy manner from the hairline on the right side, and the hairline on the left side has also grown in more clearly.

 
Even more surprising is the change in hair texture and color.
In the photo of the top of her head, the shine of her hair has increased dramatically, making her look like a completely different person.It has transformed into a dazzlingly healthy-looking color.

 
What surprises him the most is that he actually feels like his gray hair has decreased.
The gray hairs that were abundant around the right side of my hairline have now transformed into a deep, dark color, even in photographs.
Since hair color is influenced by the condition of the scalp, this can be seen as evidence that healthy black hair has grown as a result of an improved scalp environment, meaning that the "condition of the skin (scalp)," which is the foundation for hair color, has fundamentally improved.

[Case Study] Second staff member: Increased density and radiant shine even in her 40s

These staff members alsoSimilarly, the density of my hairline increased after just one month.
She's in her 40s, but thanks to her meticulous daily care, she has almost no gray hair.
The fact that she felt her already lustrous hair had become "even shinier" speaks volumes about the high potential of this serum.

The fact that just one month of skincare using cosmetics can result in such a clear before-and-after difference in hair density is medically plausible and I believe it supports the effectiveness of this serum.

The importance of reducing damage from hair coloring

What the two cases I presented have in common is,The key point is that the hair is "not colored."
Since starting work at Dr. Touhi Clinic and examining the scalps of many patients with a microscope every day, the awareness of the staff has changed dramatically.

When you witness firsthand how hair dye can seep into the scalp and cause pigment to become embedded, you begin to feel that "hair coloring is a dangerous thing for the scalp."
Today, I heard from a staff member that "I used to get my hair colored every month, but now I only get it done every three to four months."
Because we see our patients' scalp conditions every day, we feel a strong sense of urgency regarding the "burden caused by hair coloring," and this concern has become very strong among our staff.The idea that "taking care of your scalp is the most important thing" has become widespread.

Also, at an event I had the opportunity to examine the scalps of many elderly people, and I noticed that in many cases, scalps that had been repeatedly dyed or colored for many years without proper scalp care had lost their healthy paleness and turned brownish.
To protect the future of your hair, minimizing damage to your scalp is key.
Just like with your face, how you minimize damage to your scalp and take care of it will determine the fate of your hair 10 or 20 years from now.

Features of "Scalp Beauty Serum EX"

Based on the expertise we've developed in scalp serums at our clinic over the past 15 years, we have now created a new product incorporating regenerative medicine principles.

The most distinctive feature of this product is its generous inclusion of "placenta-derived exosomes (stem cell culture supernatant)."
Furthermore, it also contains an ingredient called "Capixyl," which has hair growth-promoting effects.
This is a noteworthy ingredient that is theoretically said to be about three times more effective than minoxidil, which is also known for its hair growth effects.

Capixyl was developed as a "cosmetic ingredient" rather than a pharmaceutical, so its use is strictly limited to topical application as a cosmetic raw material. Unlike oral medications that penetrate the entire body, the fact that so many positive changes appeared in multiple staff members in such a short period of time through topical application (applying it to the skin) has reaffirmed my confidence as a physician that this product can be recommended with ease.

The peace of mind of being able to use it without taking it orally

Many people are concerned about their hair, but are hesitant to take medication because they are worried about side effects.
For such people, a beauty serum that can be incorporated into their daily routine—for moisturizing after washing their hair, protecting against UV rays, and styling their hair before going out—is a very reassuring option.
Before embarking on full-scale medical treatment, firstUsing high-performance hair care products to prepare the hair's condition at the early stages when you notice a loss of firmness and elasticity is an extremely effective way to protect your hair in the future..

Summary

In this article, we discussed the importance of scalp care based on real-life changes experienced by our clinic staff.
The surprise at how much of a difference cosmetic care can make is something we, the staff, feel most strongly because we ourselves have actually used the products and experienced their effectiveness firsthand.
Recently, more and more patients at our clinic are receiving "intravenous drips" and "infusion treatments" based on the latest knowledge, but the foundation of these treatments is still daily care at home.

If you're hesitant about treatment because you're afraid of side effects or injections, interested in regenerative medicine, or unsure what your scalp needs right now, please feel free to come in for a consultation. We'll suggest the best combination for your scalp condition.

With the right knowledge, you can "avoid damage to your hair and scalp" and "moisturize your scalp and deliver high-quality nutrients."
This simple repetition is the quickest way to restore hair density and shine.
Try incorporating skincare based on regenerative medicine principles into your daily home care routine.
