Benefits

Stimulates New Hair Growth from Dormant Follicles:
In a 12-week consumer trial with 94 users, 71% noticed new hair growth. Rosemary oil increases scalp microcirculation and is widely recognised as the most studied natural ingredient for hair growth, a 2015 clinical study found it as effective as 2% Minoxidil over 6 months, with fewer side effects. Bhringraj, traditionally called the 'king of hair herbs' in Ayurveda, works alongside Rosemary to wake up dormant follicles and support the hair's natural renewal cycle from the root.

Reduces Hair Fall, Shedding & Breakage:
70% of consumer-trial users reported less hair in their brush, shower and on their pillow after 12 weeks of consistent use. Amla — Ayurveda's richest natural source of Vitamin C — strengthens hair at the root and reduces premature shedding. Sesame and Castor Oils deliver zinc and omega-6 fatty acids that fortify the hair shaft, prevent breakage and lock moisture into damaged strands.

Calms Stress-Related & Hormonal Hair Loss:
Brahmi and Fenugreek are rich in magnesium, B-complex vitamins and tryptophan — nutrients that calm the nervous system and support the scalp through periods of postpartum recovery, peri-menopause, anxiety and prolonged stress. This Ayurvedic blend addresses one of the most overlooked drivers of hair fall in women: hormonal imbalance.

Strengthens, Thickens & Adds Density:
Sesame Oil delivers copper and zinc to thicken individual hair strands, while Fenugreek and Brahmi support collagen production for fuller, denser hair over time. The result is visibly more volume, less scalp showing through and stronger strands that resist breakage from heat, styling and environmental stress.

Nourishes Dry, Brittle Hair & Soothes the Scalp:
Carrot Seed Oil and Castor Oil deliver Vitamin A, Vitamin E and essential fatty acids to deeply moisturise dry or damaged strands — restoring elasticity, softness and shine. Rosemary and Bhringraj's natural anti-inflammatory action also calms itchy, flaky scalps, addressing scalp imbalance that's often a hidden cause of hair fall.

How to Use

1. Section your hair: Part your hair into sections to ensure the oil reaches the scalp and roots evenly.

2. Apply to scalp and lengths: Using your fingertips, apply the oil directly to your scalp and work it through the mid-lengths to ends.

3. Massage gently: Massage your scalp in circular motions for 5–10 minutes to stimulate blood circulation and boost absorption.

4. Leave it in: Let the oil sit for at least 1–2 hours or overnight for deeper nourishment and maximum growth benefits.

5. Wash thoroughly: Rinse out with Ayumi Growth shampoo, and follow with Growth conditioner if needed, to leave your hair soft, nourished, and refreshed.

Safety Precautions
  • Suitable for adults and children aged 12+.
  • For external use only.
  • If you are pregnant, breastfeeding, on hair-loss medication, or have any scalp condition, consult a qualified healthcare practitioner before use.
  • Discontinue if irritation occurs.
  • Patch test recommended for sensitive scalps.
  • Pre-wash treatment for external use on scalp and hair only.
  • Avoid contact with eyes — rinse thoroughly with water if contact occurs.
  • Store below 25°C in a cool, dry place out of direct sunlight. Keep tightly sealed.
Scientific Evidence & Quality Assurance

Study 1 — Ayumi 12-Week Consumer Trial (94 Users)

Independent 12-week consumer trial conducted with 94 participants experiencing thinning hair, hair fall or slow growth. Results after 12 weeks of consistent use of Ayumi Rosemary Hair Growth Oil: 71% of participants noticed visible new hair growth, and 70% reported a reduction in hair fall and shedding. Laboratory research alongside the trial confirmed the formula stimulates hair follicles at a cellular level and supports the natural hair growth cycle.

Study 2 — Rosemary Oil vs 2% Minoxidil (Panahi et al., 2015)

Randomised comparative trial of rosemary essential oil against 2% Minoxidil over 6 months in 100 patients with androgenetic alopecia (50 in each group, applied twice daily). At the 3-month endpoint, neither group showed a significant change in mean hair count. However, both groups experienced a significant increase in hair count at the 6-month endpoint compared with baseline (p<0.05). Importantly, the rosemary oil group reported significantly less scalp itching as a side effect compared to the minoxidil group, supporting rosemary oil as a comparable natural alternative with a better tolerability profile.

Study 3 — Bhringraj (Eclipta alba) Hair Growth Activity (Roy et al., 2008)

In-vivo study evaluating the topical application of Eclipta alba (Bhringraj) extract on hair growth in male albino rats. The study demonstrated that Eclipta alba significantly accelerated the transition from the telogen (resting) phase to the anagen (growth) phase, increased follicular density, and enhanced hair length compared to control. Subsequent mechanism research (Begum et al., 2015) confirmed that Eclipta alba stimulates hair matrix keratinocyte proliferation and downregulates TGF-β1 expression — supporting its traditional Ayurvedic use as a hair-growth promoter and validating the inclusion of Bhringraj as a hero ingredient in Ayumi's formulation.

FAQ

Does Rosemary Hair Growth Oil really work for hair fall and thinning?

Yes — Ayumi Rosemary Hair Growth Oil is independently tested in a 12-week consumer trial with 94 real users. 71% noticed new hair growth and 70% reported less hair fall and shedding. Laboratory research confirms the formula stimulates hair follicles at a cellular level. It is suitable for thinning, weak or slow-growing hair.

How does rosemary oil compare to Minoxidil for hair growth?
A 2015 randomised clinical study (Panahi et al.) compared rosemary oil against 2% Minoxidil over 6 months in 100 patients. Both produced similar hair count increases, but rosemary oil users reported less scalp itching. Rosemary is now widely recognised as the most studied natural alternative to Minoxidil — without the synthetic side effects.
How long does it take to see results from rosemary hair oil?
Most users notice visibly less hair in the brush within 4-6 weeks, and new growth around the hairline within 8-12 weeks of consistent use. The 94-user study measured results at the 12-week mark. Hair growth is biologically slow — be patient and consistent for the best results.
Can I use this oil for postpartum hair loss or peri-menopause hair thinning?
Yes. The formula combines Rosemary, Bhringraj, Amla, Brahmi and Fenugreek — Ayurvedic herbs traditionally used to support hair through periods of hormonal change. It addresses both the scalp environment (circulation, follicle stimulation) and the nutritional support (Vitamin C, B-complex, magnesium) needed during postpartum and peri-menopause hair shedding.
How do I use a pre-wash hair oil for hair growth?
A pre-wash hair oil is applied to dry scalp and hair before shampooing — it sits on the scalp for 1-2 hours or overnight, giving the Ayurvedic actives time to penetrate the scalp and stimulate the hair follicles. Section dry hair, apply Ayumi Rosemary Hair Growth Oil directly to the scalp using fingertips or the dropper, and massage in gentle circular motions for 5-10 minutes — don't skip the massage, it drives the oil into the scalp where new growth begins. Leave on for at least 1-2 hours, or overnight for deepest nourishment. Wash out thoroughly with Ayumi Growth Shampoo. Use 2-3 times per week. The pre-wash ritual is the most effective way to use a hair oil for growth.
Is rosemary hair oil safe for colour-treated, chemically processed or sensitive scalps?
Yes. Ayumi Rosemary Hair Growth Oil is free from mineral oil, silicones, parabens, sulphates and synthetic fragrance. It is suitable for colour-treated, permed, chemically straightened and sensitive scalps. We recommend a patch test on the inner forearm 24 hours before first scalp application.
Is this oil suitable for afro, curly or textured hair?
Yes. The lightweight Ayurvedic blend supports moisture retention, scalp nourishment and breakage reduction across all textures — including 3a-4c curl patterns. The oils penetrate the hair shaft to support length retention and reduce breakage at the root.
How is this different from Mielle Rosemary Mint Hair Oil or Fable & Mane HoliRoots?
Ayumi Rosemary Hair Growth Oil combines clinically tested Ayurvedic actives — Rosemary, Bhringraj (king of hair herbs), Amla, Brahmi — with a 12-week consumer trial showing 71% new growth and 70% less hair fall. Unlike many viral oils, it's independently tested and free from mineral oil, silicones and synthetic additives. Made and tested in the UK.
