In a 6-month single-blind randomised trial of 100 men, topical rosemary oil raised hair count from baseline to a degree matching 2% minoxidil (active class), with less itching (PMID 25842469, Scopus cited-by 97). The effect builds over months, not overnight, and is not a cure. Tara's serum is built on this same rosemary for hair loss.

Rosemary leaf extract inhibits testosterone 5-alpha-reductase by 82.4–94.6% in vitro via 12-methoxycarnosic acid and promoted regrowth in a testosterone-induced animal model (PMID 22517595, Scopus cited-by 87). These are lab and animal findings, not human, and thickening takes months. Tara's serum applies this mechanism for hair growth and thickening.

The randomised rosemary trial measured hair count at 3 and 6 months, with gains appearing over that window, not within days (PMID 25842469, Scopus cited-by 97). The hair cycle is inherently slow, so consistent daily use for at least three months is advised. Tara's rosemary serum follows the same evidence-based timeline.

The strongest human evidence is a randomised trial where rosemary oil matched 2% minoxidil (active class) on hair count (PMID 25842469, Scopus cited-by 97). A serum is a targeted formula pairing rosemary with follicle-supporting biotinyl-GHK peptide (structural read-across to GHK-Cu, PMID 29986520, manufacturer-funded review), whereas oil is a single ingredient. Tara's serum builds on rosemary in a concentrated formula.

In the comparative randomised trial, scalp itching was reported significantly less often with rosemary than with minoxidil (active class) at 3 and 6 months (PMID 25842469, Scopus cited-by 97), indicating good tolerability. Individual irritation can still occur, so a patch test is advised. We make no claim to treat or cure any condition. Tara's serum is for daily scalp use.

Our serum combines the power of rosemary and peptides with hydrolyzed keratin and Larix europaea wood extract, revitalizing follicles, calming scalp irritation and promoting healthier, thicker hair.

For optimal results, apply the serum daily. After towel‑drying or on dry hair, massage the contents of one pipette along the hairline, parting, sides and back of the scalp. This product does not require rinsing, so you can style as usual.

Yes, our serum benefits all hair types by stimulating the follicles and increasing hair density.

No, all our serums are water‑based and lightweight. They absorb quickly into the scalp, leaving no residue and preserving the hair’s natural texture.

Yes, our serum works well with other hair care products. For best density results, we recommend using it together with our Shampoo and Conditioner from the Rosemary + Peptides collection.

The bottle contains 50 mL of product, which typically lasts one month with daily use.

Many clients begin to notice improvements in texture after a few uses, and changes in hair density between 4 and 6 weeks of consistent daily use. The scalp and follicles need time to renew and grow. 

Yes, the serum is dermatologically tested and classified as Non‑Irritating. It is fully suitable for sensitive scalps.

While its primary objective is hair density, ingredients like rosemary and peptides help maintain a healthy scalp, which can reduce dandruff over time.

Yes — for better absorption, apply the serum to towel‑dried hair after washing.
