Why Did We Make This?
With more and more environmental stressors pervading our lives, many people are seeing their hair start to gray and thin earlier than ever. These effects of oxidative stress can not only affect one’s appearance and confidence, but it’s also an issue of hair health when strands become thinner, drier, and more brittle than before. Covering up grays with color treatments is not only time-consuming and expensive, but it can also damage and weaken hair even further.
Inspired by the four distinct seasons in Japan and the ongoing cycle of rebirth in nature, we strived to find a way to achieve hair’s own rebirth: to return to its healthiest, liveliest season of growth via simple at-home treatment. Our research and development team spent 12 years perfecting the science of this formula, sourcing efficacious ingredients and processing techniques from Japan and around the world. By analyzing existing functions in nature and harnessing the power of peptides and potent botanicals, we created a proprietary formula to promote follicle renewal for restored color and a return to lively, youthful hair. Like new seeds sprouting in spring, strands emerge stronger, fuller, and more vibrant so that your confidence can bloom with ease.

What Is It?
Return to you with our daily scalp essence that combats the root causes of visible signs of aging in our hair, such as graying and thinning. Our team spent 12 years developing the perfect blend of biomimetic peptides and botanicals to revitalize hair from the root. Paired with red clover flower extract, these key peptides combine forces to protect follicles and stimulate melanin production, supporting thicker and fuller strands while working to restore hair’s natural pigment and defend against oxidation. The lightweight formula also soothes and improves scalp health to help strengthen hair and create an optimal environment for healthier growth. With consistent use, Saisei’s results are clinically proven to be seen in as little as 3 months.
What Does It Do?
Stress and time are your hair’s biggest enemies. Saisei combats both.
Thicker, Fuller Looking Hair
Our biomimetic peptides help anchor the hair fiber into the scalp which can strengthen strands and target the causes of hair loss. When used with red clover extract, it revitalizes hair follicles, can improve blood circulation, and help nourish and oxygenate the roots, which can increase the thickness, volume and strength of hair. 78%* agreed that the Saisei Collection helps visibly improve hair density and that hair looks and feels thicker after 90 days of use.
Restores Hair’s Natural Pigment
The natural color of our hair comes from melanin in the hair bulb, where new hair cells are formed. As we encounter age or stress, the melanin in our hair gets depleted, and the pigment in our hair starts to fade. It’s possible to slow down and counter this process by stimulating the production of melanin as well as reducing the effects of oxidative stress that affect melanin accumulation. The specific sequences in our curated biomimetic peptides promote the migration and accumulation of melanin in the bulb, which helps restore pigment at the root as hair grows. Pairing the peptides with nutrient-rich red clover and rosebay extracts has a synergistic effect that helps enhance melanin production, accumulation, and protection while promoting overall scalp health and fuller-feeling, revitalized strands. Supercharged antioxidants from apple extract also help with maintaining hair’s natural pigmentation and thickness.
Protects From 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 imbalance grows larger with age, as the body’s production of free radicals increases and its defense mechanisms decrease. The damage of cellular structures, including lipids and proteins, can be pivotal in visible signs of hair aging such as graying, thinning, changes in texture, and slower growth. Ingredients rich in antioxidants and with strengthening properties, including bamboo extract, black spruce bark extract, and alpine rose extract, can help protect hair from endogenous free radical damage and environmental stressors.
Scalp Health
Scalp health is essential for healthy hair, and an imbalanced scalp that isn’t well cared for often leads to other issues like irritation, dryness, and excessive oiliness. Keeping the scalp hydrated and maintaining the skin barrier are key ways to aid protecting the scalp from irritation and support an optimal environment for healthier hair growth. Rosebay extract, a plant that is able to regrow and thrive even in areas affected by wildfires, helps soothe the scalp along with apple extract. Anti-inflammatory and vitamin-rich seaweed extract and algae extract help add and retain moisture.
