Scalp Science

The scalp microbiome is extremely delicate and has a low barrier function, meaning it has difficulty maintaining moisture and is highly susceptible to oxidative damage. This damage can directly disrupt the hair growth cycle, causing thinning, shedding, and premature hair loss.

Our Stem Cell Scalp Serum is rich in phytonutrients that have been studied and shown to have incredible longevity properties, revitalizing hair stem cells and protecting the scalp microbiome. With the added benefits of Aloe Vera (1%) and Bamboo Extracts (2%), this scalp treatment works to hydrate the scalp to provide the optimal environment that supports hair follicle health and fortifies roots for fuller + thicker feeling hair with overall less shedding.

FAQ

  • Can the serum be applied to wet or dry hair?
    It can be applied to both! For optimal results, we recommend applying the serum daily on clean, damp hair, or on a dry scalp in the evenings as an overnight treatment. The serum is intended to absorb into the scalp and should not be immediately washed or rinsed off.


  • Will the Stem Cell Scalp Serum help the look + feel of hair loss?
    When suffering from hair loss, the telogen (resting) phase of the hair growth cycle is prolonged and the transition to the anagen (growth) phase becomes more difficult. Hair becomes thinner and the percentage of hair transitioning to the telogen phase continues to increase. The Stem Cell Serum is formulated with clinically validated ingredients that create an optimal environment for roots + protects hair follicles to lessen the first signs of visible shedding and thinning.


  • What are typical signs of aging in the scalp and hair?
    Over time, the scalp begins to produce less collagen, the hair follicles get smaller, and the rate of hair growth slows. This can result in less hydrated and thinner hair, with increased fallout. Consistent use of an anti-aging treatment protects the longevity of the scalp to combat the natural aging process.
