A powerful concentrate designed to stimulate the scalp for stronger hair production. It boosts microcirculation to the follicles, increasing their supply of oxygen and nutrients while accelerating the rate at which they produce hair during the growth cycle. Combined with an optimal dose of peptides, it soothes and strengthens the follicles to reduce shedding and helps thinning hair grow back stronger and fuller.

Key Benefits

Targets the DHT pathway behind hair loss: biochanin A from Red Clover inhibits human type-2 5α-reductase, the scalp-follicle enzyme that converts testosterone to follicle-miniaturising DHT (PMID 11931850; Scopus cited-by 230). A 5α-reductase argument, not a cure claim.
Built around onion (Allium cepa): its flavonoid quercetin accelerated hair regeneration and increased perifollicular microvasculature via HIF-1α in an in-vivo model (PMID 37285263; Scopus cited-by 34). Mechanism studied with purified quercetin, not onion juice — and crude 87% onion-juice regrowth data is not a claim for this serum.
Peptide complex benchmarked against the active class for hair growth: a 24-week independent triple-blind RCT (N=32) found a biochanin A + acetyl tetrapeptide-3 + ginseng combination raised terminal hair count +8.3% versus +8.7% for 3% topical minoxidil, no significant between-group difference (PMID 33584955). Underpowered for formal equivalence; minoxidil cited only as the matched class.
Adds hydrolyzed keratin for the fibre you already have: mid-MW keratin peptides penetrate the hair cortex and raised break stress ~18.6% versus controls (PMID 33037625; manufacturer-funded, single-application ex vivo) — supporting thickening (تكثيف) and length retention as strands resist breakage.
A scalp serum (سيروم البصل للشعر) that works on follicles, fibre and the DHT pathway at once — formulated for daily use on the scalp (فروة الرأس). Not a treatment for alopecia areata, androgenetic alopecia or any diagnosed condition.

How to Use

Apply 1 dropper directly to the scalp on wet or dry hair. Distribute evenly along part lines, the sides and the back. Gently massage with the fingertips to aid absorption. Do not rinse; style as usual. Daily use recommended.

Fragrance

A hair fragrance that opens with luminous lilac, apple and strawberry freshness, enriched by floral elegance of jasmine and muguet, and settles into the warm, enveloping base of sandalwood and heliotrope—leaving a scent of care, beauty and confidence.

Red Onion Extract

Stops mechanical hair loss by reinforcing keratin bonds with no residual odor.

Capixyl™ (Acetyl Tetrapeptide-3)

A biomimetic peptide that anchors the root and fights follicle miniaturization.

Hydrolyzed Keratin

The hair’s fundamental protein, micronized to repair chemical and thermal damage.

Yeast Extract

Cellular bio‑energy that drives keratin synthesis and growth.

Niacinamide (Vitamin B3)

A cellular energizer that improves keratin synthesis and scalp health.

Soybean Seed Extract

A bio‑stimulant rich in glycoproteins that energizes the follicle and extends its vitality.

Red Clover Extract

A botanical rich in plant isoflavones that calms the hormones behind hair loss and feeds the follicle.

How long until onion starts working on hair?

In a 2002 controlled study (N=38), twice-daily topical onion juice was linked to visible regrowth in 20 of 23 users at six weeks, versus 2 of 15 in the water arm (PMID 12126069; Scopus cited-by 83). That is crude-juice data, not a product. Tara's onion scalp serum pairs onion with peptides, used consistently over several weeks.

What causes heavy hair loss?

A major driver is DHT, produced by type-2 5α-reductase — the isoform dominating the scalp follicle — which miniaturises follicles. Biochanin A from Red Clover inhibits this human enzyme far more potently against the type-2 isoform (PMID 11931850; Scopus cited-by 230). Tara's serum contains this complex; heavy or sudden shedding warrants a doctor.

What is the best serum for hair growth and length?

No single serum is proven "best" for everyone, but quercetin (an onion flavonoid) accelerated hair regeneration and raised perifollicular microvasculature via HIF-1α in an in-vivo model (PMID 37285263; Scopus cited-by 34) — though the mechanism was studied with purified quercetin, not onion. Tara's serum combines onion with peptides to support growth, not exaggerated promises.

Is a peptide serum as effective as a hair-loss spray?

In a 24-week independent triple-blind RCT (N=32), a biochanin A + acetyl tetrapeptide-3 + ginseng combination raised terminal hair count +8.3% versus +8.7% for 3% topical minoxidil, with no significant between-group difference (PMID 33584955). N=32 is underpowered for formal equivalence, and minoxidil is referenced only as the matched class. Tara's serum carries that same peptide.

How do I use onion serum to thicken hair?

Hydrolyzed keratin is what addresses the fibre itself: mid-MW keratin peptides penetrate the hair cortex and raised break stress by ~18.6% versus controls (PMID 33037625; manufacturer-funded, single-application ex vivo), so strands resist breakage and read as fuller. With Tara's onion serum, apply to a dry or damp scalp and massage in gently, daily.
