Supercritical CO₂ Rosemary Extract
Cold-extracted to preserve carnosic acid and ursolic acid — the two compounds shown to stimulate scalp circulation and slow follicular miniaturisation.
Triple Hydrolyzed Keratin
Three molecular weights penetrate the cuticle, mid-shaft, and cortex — rebuilding broken bonds and visibly thickening each strand from within.
Biotin Complex (B7)
The single nutrient most consistently linked to hair strength in clinical literature. Delivered topically, where the follicle can use it immediately.
Panthenol (Pro-Vitamin B5)
Locks moisture deep into the hair shaft. Cuts breakage, calms the scalp, and gives lifeless hair its bounce back.

Carnosic acid in rosemary widens micro-capillaries at the follicle base. More blood flow = more oxygen, more nutrients, stronger anchor for each strand.
Rosemary's ursolic acid helps shield follicles from DHT-driven miniaturisation — the leading cause of pattern thinning in both women and men.
Keeps more follicles in the anagen (active growth) phase for longer. Translation: less shedding, more new growth coming through.
Rosemary is naturally antimicrobial and anti-inflammatory. Calms itch, redness, and flaking without harsh sulphates or coal-tar derivatives.
Sulphate-free lather built on coconut-derived surfactants. Cleans buildup and excess sebum without stripping the scalp's protective lipid barrier.

How this compares to daily life
Ethically sourced, sustainably produced
Your 90-Day Hair Recovery
From first wash to visibly fuller hair
Calmer Scalp, Fresh Start
Scalp feels noticeably calmer from the first wash. Itching and flakes settle down within days. The active compounds begin reaching the follicle base.
Less Shedding, Healthier Strands
Fewer hairs in the drain and on your pillow. Strands feel stronger and look shinier. You're still on your first bottle — the real change is building underneath.
Baby Hairs at the Hairline
Tiny new hairs start appearing along the hairline and temples. Friends and family begin to notice — your ponytail feels thicker between your fingers.
Protocol Complete — Visible Density
Visibly fuller, denser hair. Less breakage, less shedding, more hairs in the active growth phase. Continue with one bottle every 2 months to maintain results.
Ancient Roots, Modern Results
Long before pharmaceuticals, the Mediterranean world had already chosen one herb as its hair tonic of choice.
Rosemary Was Sacred
From the cliffs of Greece to the gardens of Rome, rosemary was prized as a healing herb. Greek students wore rosemary garlands at exams to sharpen memory. Hippocrates prescribed it for circulation and strength. And women braided it into their hair for thickness, shine, and to protect against thinning. Two thousand years later, science finally caught up — confirming that rosemary stimulates scalp circulation, protects follicles from DHT, and rivals the most prescribed hair-loss drug in head-to-head clinical trials.
Reviews
100,000+ people have rediscovered their hair with TGIDEAS Rosemary Shampoo
Backed by Science
Our formulation is built on published clinical research — including the landmark 2015 head-to-head trial where rosemary matched the leading prescription hair-loss treatment.
Rosemary Oil vs Minoxidil 2% for Androgenetic Alopecia
A six-month randomized comparative trial showed rosemary oil matched minoxidil 2% — the gold-standard hair-loss drug — in increasing hair count, with significantly less scalp itching reported in the rosemary group.
Rosmarinus officinalis Leaf Extract for Hair Regrowth
In a controlled animal study, topical rosemary leaf extract significantly accelerated hair regrowth and increased follicle density compared to vehicle control — confirming a direct effect on the follicle, not just the scalp surface.
Carnosic Acid Stimulates Hair Follicle Stem Cells
Carnosic acid — one of rosemary's principal active compounds — was shown to stimulate dermal papilla cells and activate hair follicle stem cells, both critical drivers of the anagen (growth) phase.
Botanical Hair Growth Stimulants: A Systematic Review
A 2020 systematic review of 28 clinical studies identified rosemary, biotin, and saw palmetto as the three plant-derived compounds with the strongest evidence base for stimulating hair growth and reducing shedding.
Individual results vary. Studies referenced involve full clinical protocols and may not directly replicate at-home use.
