Algaktiv Densidyl (Chlorella, Spirulina & Ascorbic Acid)

Algaktiv Densidyl is a patented active complex that brings together three ingredients with complementary roles in scalp and follicle health: Chlorella emersonii, a freshwater microalgae dense in amino acids, vitamins, and growth factors; Spirulina maxima, a blue-green microalgae renowned for its protein and antioxidant content; and ascorbic acid, the biologically active form of vitamin C.

Each component contributes a distinct set of bioactive compounds. Together, they create a nutrient-rich environment that supports follicle cell activity, collagen synthesis in the scalp, and protection against the oxidative stress that compromises both hair density and pigmentation over time.

At Arey, Algaktiv Densidyl is included in Good Night, Grey®, our overnight scalp serum, where its nutrient delivery and follicle-energizing properties work during the body's natural repair cycle.

Hair density depends on the health and activity of the follicle at every stage of the growth cycle. Algaktiv Densidyl supports this at the cellular level through three distinct mechanisms.

Chlorella Emersonii Extract is one of the most nutrient-dense organisms on earth, containing a complete amino acid profile, B vitamins, chlorophyll, and growth factor-like compounds called Chlorella Growth Factor (CGF). In scalp care, CGF has been studied for its ability to stimulate cell renewal and support the proliferation of follicle cells, contributing to a more active and productive growth cycle. Chlorella's rich nutrient profile also provides the building blocks the follicle needs to produce strong, healthy hair fiber.

Spirulina Maxima Extract contributes a high concentration of protein, including all essential amino acids, alongside phycocyanin, its primary antioxidant pigment. Phycocyanin has demonstrated potent free radical scavenging activity in research, helping to neutralize oxidative stress at the scalp and follicle level. Spirulina is also a source of iron and B vitamins, nutrients that play a direct role in supporting healthy hair growth and reducing hair loss associated with nutritional deficiency.

Ascorbic Acid (Vitamin C) serves a dual function in the complex. As an antioxidant, it reinforces the free radical protection provided by spirulina and chlorella. As a cofactor in collagen synthesis, it supports the structural integrity of the scalp dermis, which is the tissue in which hair follicles are anchored. Vitamin C also enhances the bioavailability of iron from the algae components, making the complex more effective as a whole than the sum of its parts.

The Mela-9® Complex targets grey hair through multiple pathways, and density is one of the dimensions that matters most to the people experiencing it. Grey hair is often accompanied by changes in hair texture and perceived fullness, and addressing follicle activity and structural support is part of how we approach that. Algaktiv Densidyl brings a nutrient density and cellular energy to the overnight serum that complements the pigmentation and antioxidant actives in the rest of the blend.

We include it specifically in Good Night, Grey® because overnight is when follicle cell renewal is most active. Delivering chlorella, spirulina, and ascorbic acid during that window gives the complex the best conditions to support the growth cycle and scalp environment when the body is already primed to repair and regenerate.
