Red Onion Extract

Allium Cepa (Onion) Bulb Extract

An organosulphur and flavonoid scalp botanical — density is carried by Capixyl, not onion.

About This Ingredient

A concentrated red onion bulb extract, rich in quercetin and organosulphur compounds, that conditions the scalp. The famous 87% regrowth figure comes from raw onion juice on alopecia areata — an autoimmune patchy hair loss, not general thinning — and does not transfer to this cosmetic dose. In Tara's formulas the measured density work is done by the Capixyl/biochanin-A peptide, which matched 3% minoxidil on hair count in an independent 24-week trial (Lueangarun, 2020). Onion does not regrow hair at the dose shipped.

Key Benefits

Stops Mechanical Hair Loss

Bioavailable sulfur rebuilds the disulfide bridges that hold the fiber together, stopping breakage‑related loss from the first application.
Odorless Stimulation

All the stimulatory power of quercetin, biotechnologically purified to remove odor while preserving efficacy.
Instant Thickness

Infuses minerals directly into the fiber so you feel your hair denser, stronger, and more resilient instantly.
Strengthened Root

Reinforces anchoring proteins that hold the strand to the scalp, reducing loss during brushing and washing.
