We, too, are in denial, but we have to accept that hair loss is a common progression of life. It can be a natural occurrence as we age, or it can be a result of alopecia, chronic illness, stress, hormonal changes, or a number of other factors. One thing we can likely all agree on, though, is it messes with our confidence. Hair is a form of expression and even our own personal, everyday accessory. When it doesn’t feel or appear like it used to, it changes our whole look.

August is National Hair Loss Awareness Month, so we think it’s the perfect time to shed light on NatureLab.TOKYO’s high-performance system designed to target thinning tresses: the Saisei Collection. This groundbreaking restorative trio was developed over 12 years to address signs of visibly aging hair such as thinning, graying, and brittleness. In Japanese, ‘saisei’ means rebirth or revival. The seasonal cycle of rebirth in nature was one of the original inspirations for the collection, and with consistent use, Saisei can bring new life to your hair.  

The collection—which consists of Saisei Stress Defense Amino Acid Shampoo, Saisei Restoring Therapy Conditioner and Saisei Biomimetic Peptide Treatment Essence—works to counter thinning by addressing the most common root cause: oxidative stress. Oxidative stress occurs when reactive oxygen species, or free radicals, outnumber the body’s natural defense mechanisms and progressively cause cell damage; this damage can be pivotal in visible signs of hair aging such as graying, thinning, changes in texture, and slower growth. All three products work together harmoniously to promote scalp health, provide antioxidants and nutrients to defend against oxidative stress, and revitalize follicles from the root. The key, however, is to be diligent with daily use of the treatment essence, the most potent formula in the collection. A day here, a few days there? That won’t cut it. It’s 2025, we all want quick, immediate results, but changes in healthier hair growth take some time. After three months of consistent use, 76% noticed that hair looked and felt significantly denser and fuller, and 84% noticed an improvement in healthier hair growth.**  

To encourage regular use, users have suggested implementing application of the treatment into a skincare routine (whichever time of day works best for you). Others have also incorporated mantras into their daily ritual. You can get creative here and make it fun. Whether that means lighting a candle and having an at-home spa moment, or putting on calming music in the background, it’s your me-time. 

So, how did we get here? Our game-changing, fragrance-free treatment essence works its magic by way of several key ingredients. First, biomimetic peptides promote greater strength, thickness and fullness. These lab-made molecules mimic the structure and function of naturally occurring peptides in the body. In turn, they offer melanin production support, which helps restore natural hair color while also promoting greater strength, thickness, and fullness for strands. 

Then we have rosebay extract, which helps soothe the scalp for a healthier microbiome. Last, we’ve got red clover extract, which contains a rich source of nutrients and isoflavones that support fuller hair. Paired with the aforementioned biomimetic peptides, it can help revitalize hair follicles for stronger, thicker-feeling hair. Just some plant-based goodness designed to change how you feel about your strands! And as we touched on above, this works most effectively when combined with the collection’s shampoo and conditioner. The end result? Overall improved scalp health and moisture levels, with silicone-free conditioning that protects from environmental stressors.
