Clinical Testing Report for Mamaearth Rosemary Hair Growth Oil

A: It is clinically tested to grow new hair in 12 weeks, in a study on healthy human volunteers under an Ethics Committee approved protocol, supervised by a dermatologist and Principal Investigator. The certificate reports the outcome qualitatively, which is why this page describes what was certified rather than quoting a figure.

A: Twelve weeks, and that comes straight from the hair cycle: a follicle entering the growth phase needs roughly three months to produce hair long enough to see. That is why the study ran 84 days, and why consistent use across a full three months is what gets you the result the study measured.

A: The 2015 Panahi trial found that pure rosemary essential oil, applied to the scalp twice daily in men with androgenetic alopecia, produced hair count gains comparable to minoxidil 2% at six months, with less scalp itching. That is a finding about rosemary essential oil in that specific population. This is a blended cosmetic oil tested in healthy volunteers, and it is not a substitute for a medical treatment. Pattern hair loss is worth discussing with a dermatologist.

A: Yes. A few hours or overnight, then wash out. Use a pillowcase you do not mind oiling, or wrap your hair.

A: Three times a week, which is what the study protocol used. The hair cycle sets the pace, so consistency across the twelve weeks is what matters most.

A: Some people notice more hair coming out in the wash after oiling and massaging. That is usually hair which had already detached from the follicle being released - it was on its way out regardless. If shedding increases and continues for weeks, a doctor can advise.

A: Yes. It is already a blend of sunflower, coconut, almond, castor and other oils, so no further dilution is needed. If you also use a leave-on scalp serum, apply that to a clean scalp and keep the oil for pre-wash use - they work well as a sequence.

A: This study measured growth. For a hair fall endpoint, the Mamaearth Onion Hair Oil was studied on hair fall over 14 days, and the Rosemary Anti-Hair Fall Shampoo and Conditioner were tested on fibre strength and breakage.

A: It is built on sunflower and coconut oil with isopropyl myristate, which spreads fast and keeps the texture notably lighter than a pure coconut or castor oil. Like any oil, it washes out with shampoo.

A: Oiling a flaky scalp can worsen dandruff, since Malassezia feeds on lipids. Clear the dandruff first with an anti-dandruff shampoo, then reintroduce oiling.

A: Rosemary oil contains camphor, and topical use in a diluted cosmetic blend is a low-exposure situation. As with anything in pregnancy, your doctor can confirm what suits you.

A: The study was conducted on healthy volunteers. A receding hairline usually indicates androgenetic alopecia, which is a medical condition - and it is one where earlier assessment gives better outcomes, so a dermatologist is the right first step.

A: Yes. The formula is free of silicones, parabens, mineral oil and synthetic dyes.

There is a well-known randomised trial from 2015 in which pure rosemary essential oil, applied to the scalp twice daily in men with androgenetic alopecia, produced hair count gains comparable to minoxidil 2% at six months. That is published evidence for rosemary as an ingredient, and it is why rosemary anchors this formula. This product’s own evidence is a separate 12-week clinical study certifying new hair growth.

It is the most studied botanical in this category, with published work on hair growth in both a human trial and animal models, plus antioxidant and anti-inflammatory activity from rosmarinic and carnosic acid. It is also why this formula is built around it. It is not a medicine and it is not a substitute for one.

Pure rosemary essential oil must be diluted in a carrier oil before it touches your scalp - undiluted essential oil can irritate or sensitise skin. This product is already a blend, so no further dilution is needed. Massage into the scalp, leave a few hours or overnight, wash out, three times a week. Give it 12 weeks, because that is how long a new hair takes to become visible.

Start by identifying which kind you have. Breakage responds well to gentler washing, conditioning and less heat. Shedding from the root is influenced by hormones, iron and vitamin D levels and thyroid function, so a blood test is a useful step alongside topical care. This oil was studied on hair growth over 12 weeks, which is a different endpoint again.

Oils do their best work by reducing breakage and protein loss, which makes hair look fuller because more of it stays on your head. Rosemary is the ingredient in this category with the strongest published growth evidence, which is why it anchors this formula - the trial behind that used pure essential oil applied twice daily over six months, so consistency is what makes the difference.

Around 50 to 100 hairs a day is completely normal, and it always looks like more when it accumulates over several days. Heavy shedding two to three months after illness, fever, surgery or childbirth is usually telogen effluvium, which generally recovers on its own.

Iron most commonly, then vitamin D and B12, with thyroid function worth checking too. If shedding is sudden or persistent, a simple blood test is the most useful next step - it tells you what to correct, and topical care works best alongside that.

Twelve weeks, and that comes straight from the hair cycle: a follicle entering the growth phase takes around three months to produce hair long enough to see and count. This product’s study ran 84 days for exactly that reason, so consistent use across three months is what gets you the result it measured.
