Why a Scalp Serum?
Most hair-care products focus on the visible hair strand. Yet the hair strand itself has no metabolic activity; the hair fiber is produced in the follicle within the scalp. A healthy scalp contains approximately 100,000 hair follicles, with around 85–90% in the active growth phase.
That is why at Mirissa Lab, we focus on where hair begins: the scalp. We chose the Mirissa Lab Night Care Scalp Serum format to support sebum balance, moisture, barrier care and the environment around the hair roots within the same routine. Care aimed at stronger, fuller-looking hair starts not only by coating the strands, but by providing consistent, targeted scalp care.

Why Peptide Technology?
If hair strands are becoming thinner, weaker and losing volume, caring only for the outer surface of the hair may not be enough. One important factor affecting the appearance of hair is the scalp environment where the hair roots are located.
That is why we specifically selected the peptides Biotinoyl Tripeptide-1 and Acetyl Tetrapeptide-3 for our serum. Peptides are small structures made from amino acids and are used in cosmetic formulas as targeted care actives. Biotinoyl Tripeptide-1 is used to support a stronger, more resilient hair appearance, while Acetyl Tetrapeptide-3 is used to support the care environment around the hair root and help promote a fuller, denser-looking appearance.
So the issue may not simply be that the hair strand looks weak, but that the area where hair begins is not receiving enough care. This is exactly why Mirissa Lab uses peptide technology: to extend care beyond the strand and focus on the scalp and root environment.
Biotinoyl Tripeptide-1 + Acetyl Tetrapeptide-3: targeted peptide care that supports stronger, fuller and more resilient-looking hair.

What's Missing From Scalp Care?
Applying active ingredients to the scalp is not enough on its own. Creating an environment that supports the scalp's moisture, lipid balance and comfort is also an important part of consistent care.
That is why Mirissa Lab serum includes not only peptides, but also complementary scalp-care ingredients such as Squalane, Allantoin and Panthenol. Squalane provides lightweight care that supports the scalp's lipid structure, while Panthenol supports moisture and comfort and Allantoin supports soothing care.
The serum's leave-in micro-emulsion format allows actives with different properties to be applied to the scalp in a lightweight, homogeneous formula. Because it is not rinsed off after application, care does not end with the shower.
The serum is therefore not dependent on any particular shampoo. It is a targeted scalp-care step that can be applied directly to a clean scalp and can also be used on its own.
The goal is not simply to use more actives, but to build a balanced and comfortable scalp-care routine in which actives can be used consistently.
FREQUENTLY ASKED QUESTIONS
Should I apply this serum directly to the roots?
Yes. The product was developed primarily for the scalp and root area rather than the hair lengths. Part the hair, apply the serum directly to the scalp and gently distribute it with your fingertips.
Is Mirissa serum really leave-in?
Yes. Biotech Night Care Serum is a leave-in care product. It remains on the scalp after application and does not need to be rinsed out.
It says night serum. Can I only use it at night?
No. The product was developed to fit a nighttime care routine, but it does not have to be used only at night. It can also be applied to a clean scalp during the day.
Should I apply it after showering or to a dry scalp?
Either is suitable. It can be applied when the scalp is slightly damp after showering or when completely dry. The important point is that the serum reaches the scalp directly.
Will Mirissa serum make my roots oily?
Its lightweight, leave-in formula was developed for scalp use. When used in an appropriate amount, it is designed not to leave a heavy or intensely oily feel. Using more product than necessary can create heaviness at the roots.
Can I use this serum every day?
It can be used regularly according to your scalp's needs. If you are using it for the first time, you can start less frequently and increase use while observing how your scalp responds.
Will Mirissa serum completely stop hair fall?
Hair fall can have many genetic, hormonal, nutritional or health-related causes. It would therefore not be accurate to say that a cosmetic product can completely stop every type of hair fall. Mirissa serum was developed to support the care of hair prone to shedding and the scalp.
Can both women and men use Mirissa serum?
Yes. The product can be included in scalp-care routines for both women and men; it is designed around the needs of the hair and scalp rather than gender.
