The ingredients that actually do the work
Lustriva®
Clinically provenThe only hair growth ingredient with double-blind, placebo-controlled clinical trials showing significant improvement in hair thickness, growth rate, and reduced shedding in women. This is the ingredient most vitamin brands can't afford to include.
Biotin — 10,000mcg
Full clinical doseBiotin is the backbone of hair, skin, and nail health. Most hair vitamins underdose it significantly. Mary Kate delivers the full 10,000mcg — not the token 500mcg you'll find in most gummies.
Vitamin D3 — 1,000 IU
100% daily valueVitamin D deficiency is one of the leading causes of hair loss and fatigue in women. D3 is the most bioavailable form — the same type your body produces from sunlight, and the most effective at raising blood levels quickly.
Vitamin C — 90mg
100% daily valueA powerful antioxidant that supports collagen production — essential for skin elasticity and hair follicle health. Works with Vitamin E to protect cells from daily oxidative damage.
Vitamin B12 — 30mcg
500% daily valueB12 deficiency is the most common nutritional deficiency in women — and one of the biggest drivers of fatigue, brain fog, and hair thinning. In liquid form, absorption is dramatically higher than pills.
Zinc — 11mg
100% daily valueZinc plays a critical role in hair tissue growth and repair. Low zinc is directly linked to hair loss. It also supports immune function and scalp health — important for both hair and clear skin.
