Ingredient Spotlight — Science That Speaks Subtlety

Biotin (Vitamin B7)

Biotin, also known as vitamin B7, is widely associated with supporting the health of hair, skin, and nails. While dermatologists note that evidence for topical biotin directly stimulating hair growth remains limited and that deficiency is rare, it still plays a recognized role in supporting hair structure and keratin production — factors that contribute to stronger-feeling hair when paired with complementary actives.

Amino Acid Complex

Hair is built from keratin — a protein composed of amino acids. Including a spectrum of amino acids (like arginine, serine, threonine) helps reinforce the protein matrix that gives hair its strength and elasticity, contributing to overall résilience and smoother surface appearance.

Pea Sprout Extract

Research on Pisum sativum (pea sprout) extract — a natural botanical — suggests it may promote hair density and reduce shedding by modulating key factors in the hair growth cycle, including upregulating genes associated with follicle activity and extending the growth phase.

Vitamin E & Antioxidants

Vitamin E — a potent antioxidant — helps nourish the scalp and protect cellular structures from oxidative stress, supporting an optimal environment for healthy-feeling hair.

Squalane

A luxurious, lightweight hydrator, squalane mirrors the skin’s own natural lipids and helps maintain essential moisture without weighing down strands, contributing to softness and sheen. 

Botanical Brightening Blend

Yuzu oil’s uplifting aroma creates a scented interlude that enlivens the senses, while sage, basil, turmeric, neem, and red algae deliver a rich suite of botanical support for scalp balance and scalp nourishment.

Ritual of Use — An Elevated Rituel

• After cleansing (towel-dry or dry hair), dispense 2–4 pumps and warm in palms.
  

• Massage into the scalp with intention — a moment to breathe deeply and anchor into your soin ritual.
  

• Glide through lengths to enhance natural sheen and reinforce surface strength.
  

• Style as usual — the featherlight, non-greasy formula layers beautifully with other products.
  

With consistent daily use, this élixir helps illuminate your hair’s natural brilliance, creating a luminous silhouette that mirrors Lumiraé’s philosophy — from quiet darkness comes radiant light.
