Mielle Rosemary Mint Scalp Oil is a hair oil designed to be used as a part of your daily hair care routine. They say that its formula contains a carefully selected blend of 30 essential oils, nutrients, and vitamins, while being paraben, sulfate, paraffin, mineral oil, and DEA free and not tested on animals.
Mielle claim that this allows their hair oil to improve length retention, nourish and condition the scalp and follicles and prevent dryness, and help smooth split ends. However, after conducting our own Mielle Rosemary Mint Scalp Oil review, it appears that these claims may not all be true.
While the company heavily push the rosemary oil, mint oil, and biotin that its formula contains, they don't make any real mention of the other 27. That is because many of them have little to no proof that they will actually be of any use.
Instead, what they do is weaken the effect that the promoted ingredients will have, as less will be able to fit in each dose. This is especially true as both rosemary oil and mint oil are quite low down on the list of ingredients.
While it is, admittedly, a fairly reasonably priced product that can be used on all hair types, it is simply highly unlikely that it will provide the benefits or split end care that it suggests. That is why we recommend you use a pure oil product, such as Toxique Serum which we rated as the number one hair oil for growth. The core difference is that they standardize the plant compounds that actually protect and nourish your hair, as well as the fact you get a lot more for your money. It also actually contains the percentages of oils in the mixture that have actually been studied. Unlike Mielle, which contains to little rosemary and mint oil for their biggest impact.
Customer reviews of Mielle Rosemary Mint Scalp Oil look pretty decent at first, as it currently holds an average rating of 4.4 out of 5 stars based on reviews from past users on Amazon.
When looking at the positive reviews, the three most common things mentioned are its ability to condition the hair, provide split end care, and not stain their pillows like other similar oils had. However, what is notably absent is any mention of it actually promoting growth or preventing hair thinning or loss.
However, when looking at the negative reviews, we see a lot of complaints that not only will it not promote growth, but it could even make thinning even worse. This is then made worse by complaints about it smelling unpleasant, being very greasy, and causing skin irritations.
Overall, this leads us to believe that, while it may be able to make your hair look and feel nicer, it is not worth it when you consider the negative effects the product can cause, and it will be no use to people who are looking to promote growth or prevent thinning, and it could even make their issues even worse.
Rosemary Oil (Rosmarinus Officinalis Leaf Oil) - Rosemary oil is an essential oil found in the rosemary plant, which is native to the Mediterranean region of Europe. It is widely used in creams, oils and ointments, as it boasts a wide range of nutrients and flavonoids that offer a huge number of benefits for both the hair and skin.
It can boost blood flow to the follicles, aiding hair growth and nutrient delivery, block DHT (dihydrotestosterone) to stop hair loss or thinning, smooth out fine lines and wrinkles, promote tighter skin, combat acne and inflamed areas of skin, and even remove visible cellulite.
Massaging rosemary oil into the skin can even offer benefits like better mental functions, mood, and overall health, and reduced stress levels, pain, and inflammation, while also acting as a natural insect repellent (1).
The only issue is, despite being the first thing mentioned on the product, rosemary oil is actually listed way down near the bottom of the Mielle Rosemary Mint Scalp Oil ingredients list. This means it is likely present in a dosage that is far too low to be of much use.
Mint Oil & Menthol (Mentha Piperita Extracts) - Mint oil and menthol are both extracts of the peppermint plant, which is a hybrid of the spearmint and watermint plants. Native to Europe and North America, these extracts are widely used, as they are very beneficial for both the hair and body and have a strong yet pleasant scent and taste.
It is often put in a topical product such as a hair oil, as it can promote growth, prevent hair loss, increase blood flow, especially to the skin and follicles, and refresh and invigorate the hair and skin.
It is then said to offer a number of additional health benefits for both the mind and body, which include an ability to relieve headaches, muscle soreness, joint pain, itching, coughs, colds, stress, pain, burns, and inflammation, and improve your mental functions and insulin sensitivity (2).
Again though, while it is not quite as far down the Mielle Rosemary Mint Scalp Oil ingredients list as rosemary oil, there are still a huge number of ingredients listed before it. This means it is highly likely that only a very small amount has been used, so the benefits that it will offer will be minimal.
Biotin - Biotin is the chemical name for vitamin b7 and it may be the single most important vitamin when it comes to the growth and maintenance of the hair. It can promote strong and healthy hair, bones, nails and skin, while preventing damage, brittleness, and any breakages (3).
Biotin use can then also help improve amino acid and nutrient metabolism, and it is extremely useful for women who are worried about losing their hair or it thinning as a result of the hormonal changes they go through during the menopause.
Unlike the other two ingredients, biotin is listed quite near the top of the Mielle Rosemary Mint Scalp Oil ingredients list, so it is possible that a sufficient dose has been used. That said, there are still a number of unproven ingredients above it, so it will still be nowhere near as useful as it could be if used properly.
Essential Oils Blend - While Mielle Rosemary Mint Scalp Oil may look OK to this point, the real issues start when you look at the ingredients that have been included beyond the three that are plastered all over the bottle.
The formula also contains glycine soja oil, ricinus communis seed oil, aloe barbadensis extract, benzyl nicotinate, carthamus tinctorius seed extract, cocos nucifera oil, eucalyptus globolus leaf oil, glycerin, lavandula angustifolia oil, melaleuca alternifolia (tea tree) leaf oil, ocimum basilicum leaf extract, oryza sativa bran oil, pogostemon cabin leaf oil, prunus amygdalus dulcis (sweet almond) oil, retinyl palmitate, salvia officinalis oil, simmondsia chinensis seed oil, tocopheryl acetate, triticum vulgare germ oil, vitis vinifera seed oil, phenoxyethanol, citronellol, limonene, and linalool.
The problem with this formula is that, while some of the ingredients have indeed been proven to aid hair growth, others have little to no evidence that they will benefit you in any way.
What makes this particularly problematic is the fact that not only is the number of ingredients present vast, but they are all also lumped into a single proprietary blend, which means we have know way of knowing how much of each is present.
You put all of this together and it appears extremely likely that the sheer number of ingredients that Mielle Rosemary Mint Scalp Oil contains means it will be almost impossible for anything to be present in a large enough dosage to be of any use to your hair at all.
Toxique Serum is an all in one natural oil that is simple to use and extremely effective. You simply massage oil into your scalp and then wait to enjoy the extensive range of benefits that it can offer.
The Toxique Serum formula also features rosemary oil and mint oil, although this time they are actually the two main ingredients. It then also includes castor oil, lavender oil, and argan oil as well.
Lavender oil has anti inflammatory properties and can soothe the skin and prevent damage to the skin or follicles, boost blood flow to the scalp, strengthen hair follicles, combat bacteria, treat acne, eczema and dry skin, prevent wrinkles or blotchy skin, aid hair growth, and leave a pleasant smell (4).
Argan oil can improve hair and skin elasticity and hydration, reduce inflammation and the signs of aging, protect against chemicals and UV rays, relieve certain skin conditions, prevent skin and hair damage, and moisturise and condition the hair and prevent it from getting dry or breaking (5).
The castor oil will then nourish the follicles with essential vitamins, minerals and fatty acids to promote growth and protect against damage and harmful bacteria, while also moisturising and conditioning the hair and skin (6).
By combining all of these ingredients and being totally transparent with its formula, you can be assured that Toxique Serum will improve your hair growth and quality in all of the ways that it claims, while only requiring you to use a small amount each day.
Mielle Rosemary Mint Scalp Oil is a supplement that claims to be a daily use oil that can improve the quality and rate of growth of your hair, without costing a fortune. Unfortunately, closer examination reveals that it simply cannot offer all of the benefits that it claims.
While the advertised ingredients are indeed very useful, it appears they are present in very small doses and surrounded by others that have little to no proof they will do anything at all.
As a result, this is simply not a product that can be relied on to produce results.
Instead, we suggest you give Toxique Girl a try. It contains most of the proven ingredients we saw in the Mielle oil, as well as a few more great additions, without any of the fillers. This means it will actually be able to produce the kind of results that you are looking for.
