Korean science for fuller, stronger, visibly revitalized hair.

In this clinical study, 30 women aged 30 to 60 used the Cosmelia hair serum daily for 12 weeks under dermatological supervision.

Here are the results measured during testing:

✓ +32% hair density – A measurable increase in the number of hairs per cm², assessed by phototrichogram.
✓ +24% hair thickness – Visibly thicker hair fibers, measured with specialized instruments.
✓ −50% hair shedding – Fewer hairs collected during standardized wash tests.
✓ 90% of participants satisfied – 27 out of 30 women reported an improvement in the overall appearance of their hair.
✓ 93% good skin tolerance – 28 out of 30 participants showed no adverse reactions during the study.
✓ Dermatological evaluation – Results reviewed and validated by the specialists who supervised the study.

Beyond the scientific measurements, what really matters is how women experience their hair transformation.

In our clinical study, 30 women aged 30 to 60 used the Cosmelia serum daily for 12 weeks.

At the end of this period, they shared their impressions so we could assess their satisfaction, their comfort of use and the changes they noticed in their hair.

✓ 93% saw visibly more voluminous hair – 28 out of 30 participants noticed fuller-looking hair, especially at the roots.
✓ 90% found their hair looked thicker – 27 out of 30 participants noticed an improvement in the look and texture of their hair.
✓ 87% noticed fewer hairs on their brush – 26 out of 30 participants reported seeing less hair fall in their daily routine.
✓ 97% loved how easy it is to use – 29 out of 30 participants found the massage applicator practical and pleasant to use.
✓ 93% want to continue their Cosmelia routine – 28 out of 30 participants said they intend to keep using the serum.

Because beyond the numbers, every head of hair tells a story.

What this evaluation verified:
How well the Cosmelia serum is tolerated with regular use on the scalp.

As part of the protocol, the specialists examined:

✓ Skin reactions – Monitoring for any redness, itching or irritation.
✓ Tolerance to daily use – Assessing how the scalp responds over repeated applications.
✓ Comfort of use – Collecting participants' feedback on how the serum felt after application.
✓ Dermatological assessment – Review of the observations by a qualified professional.

Why does this matter?
The scalp is the environment where hair grows. A hair care product must not only meet cosmetic needs, but also be suitable for regular application.

Our goal: to offer a formula with documented tolerance, so you can use it every day with confidence.

What this evaluation measures:
The change in the amount of hair shed during the period of use of the Cosmelia serum.

The protocol includes:

✓ Hair shedding measurement – Counting shed hairs using a standardized method.
✓ 12-week follow-up – Comparing observations before and after using the serum.
✓ Hair strength assessment – Analysis of relevant parameters for hair fragility, using the available methods.
✓ Participant assessment – Collecting their observations during brushing and washing.

Why does this matter?
Visibly fuller-looking hair doesn't depend on growth alone. Shedding, breakage and fiber diameter also affect the overall look of your hair.

By studying these different parameters, we aim to better understand the real effects of our formula.

Our goal: to assess whether Cosmelia helps reduce measured hair shedding and improves the look of fragile hair.
