Full disclaimer; we are not talking about the delicious squishy treats! For centuries, marshmallow root has been a highly revered ingredient in beauty routines. At the heart of this are its powerful anti-inflammatory and hydrating properties. These give it a number of hair and skin benefits that have made marshmallow root extract a hero ingredient for beauty insiders worldwide. In this article we explore the science behind marshmallow root and how to use it to boost the health and look of your skin and hair.
What is Marshmallow Root?
Marshmallow root is a herb from the Althaea officinalis plant. It is traditionally used in herbal medicine for its rich mucilage content, which gives it its soothing properties. This mucilage is a gel-like substance that becomes more potent when mixed with water. It is also packed with antioxidants, vitamins and polysaccharides. These are responsible for the benefits of marshmallow root (whole, as an extract or in powder form), helping with moisture retention, reducing irritation and protecting against environmental aggressors.
The benefits of marshmallow root for skin and hair come down to its unique make-up. It is packed with polysaccharides, which help retain moisture. So it is especially effective for dry and sensitive skin and hair. The antioxidants help combat oxidative stress and reduce the effects of environmental damage, which makes it a useful ingredient in anti-ageing formulas. Marshmallow root is also a natural anti-inflammatory, so it helps ease redness and irritation. This makes it a popular choice for people with eczema, psoriasis and other reactive skin conditions.
Benefits of Marshmallow Root for Skin
Although it has been an ancient beauty secret, marshmallow root extract is now finding its way into modern skincare. It is still not widely available in the UK, but it is a very popular ingredient in Korean skincare. The main benefits for skin include:
- Intensive hydration and moisture retention: marshmallow root works wonders for hydrating the skin. Its mucilage acts as a natural humectant, drawing water into the skin and creating a moisture-locking barrier that keeps skin supple all day. This deep hydration plumps the skin and helps smooth fine lines and texture caused by dryness.
- Soothing for sensitive skin: one of the key benefits of marshmallow root is its ability to soothe irritation. Its anti-inflammatory properties can reduce redness, swelling and discomfort, which makes it popular for skin conditions like acne, rosacea, eczema and psoriasis. It can also calm the skin after procedures like waxing, laser and chemical peels. Best of all, it is gentle enough for highly reactive or sensitive skin.
- Antioxidant anti-ageing effects: the antioxidants in marshmallow root help fight the free radicals that normally speed up skin ageing. By neutralising them, it helps soften the look of fine lines and wrinkles. Its hydrating properties also improve skin elasticity, making it look plumper and firmer.
- Enhanced skin barrier protection: the polysaccharides in it create a protective barrier over the skin, which helps protect it from pollution, UV radiation and other environmental aggressors. This barrier also reduces transepidermal water loss (TEWL), so the skin retains moisture more effectively. As a result, it lowers the chance of dryness and irritation.
- Improved skin texture and tone: thanks to its high mucilage content, it can help smooth uneven texture and soften the skin. Its anti-inflammatory properties also help even out skin tone and brighten the complexion.
Benefits of Marshmallow Root for Hair
The benefits of marshmallow root extend to the scalp and hair. Whilst it is not a common ingredient in modern hair products, there is growing use of marshmallow root extract in this space. The main benefits for hair include:
- Hydration and softness for dry hair: just as it hydrates the skin, marshmallow root also works wonders for dry, brittle hair, and it is great for curly or textured hair too. The mucilage gives a conditioning effect that softens hair, making it easier to detangle and reducing frizz. So it moisturises the hair, leaving it smoother and shinier.
- Supports a healthy scalp: it supports scalp health, which matters for healthy hair. Its anti-inflammatory properties can soothe scalp irritation, whilst its antioxidants help combat the oxidative stress that can damage the follicles. This helps support a healthy scalp environment for your hair.
- Strengthens hair and reduces breakage: the mucilage in it coats the hair shaft, adding a protective layer that guards against breakage and split ends. By strengthening the strands, it helps maintain length and improve resilience. So it is especially useful if you want to reduce damage from styling, heat or the environment.
- Detangling aid and frizz reduction: one of its unique properties is its natural slip. This makes it an ideal detangler, helping separate the strands easily and reducing tugging and breakage. For thick or curly hair, it also reduces frizz, which leaves hair smooth and well-defined.
Risks & Side Effects
Marshmallow root is generally well-tolerated and is often recommended for sensitive skin types. However, as with any ingredient, there is always a risk you might not tolerate it. It is important to do a patch test before using it to rule out any allergies or sensitivities. If you are pregnant, breastfeeding or have any health problems, check with your healthcare provider first.
How to Use Marshmallow Root for Skin & Hair Care
There are a number of ways to get the benefits of marshmallow root for your skin and hair. The easiest is buying skincare and hair products that already contain marshmallow root extract. Below are the main ways to introduce it into your beauty routine:
- Skincare products: you can find marshmallow root in a number of skincare products these days. The best way to use it is in leave-in products like essences, toners, serums, creams or face masks, so you get the most out of its soothing and hydrating properties through the day. You can also layer marshmallow products and use them alongside actives like Retinoids, exfoliating acids and vitamin C.
- Hair conditioners, masks and serums: for a deeply hydrating hair treatment, consider conditioners and masks containing marshmallow root. You can also find marshmallow root extract in leave-in serums and conditioners, which are especially great for very dry, damaged or curly hair.
You can also buy marshmallow root (whole, or as a powder or extract) and make your own beauty treatments if you are that way inclined. We would not recommend this if you have sensitive or reactive skin, scalp problems or hair loss. If you like making your own products, here are the best ways to get the benefits of marshmallow root extract and powder:
- Marshmallow root skin tonic: make a tonic by steeping marshmallow root powder or dried root in warm water. Once cooled, apply it to clean, dry skin as a hydrating, soothing leave-in treatment. You can also make a DIY mask by mixing marshmallow root with other nourishing ingredients like coconut oil and aloe vera.
- Scalp-soothing treatment: for an everyday scalp treatment, mix marshmallow root extract with oils like jojoba, argan or castor oil. Massage this blend into your scalp to boost circulation. For a deep conditioning treatment, add marshmallow root powder to your regular conditioner, or to banana, avocado or egg yolk. Apply to freshly washed hair and rinse thoroughly after 10 to 15 minutes.
Marshmallow root, like liquorice, is a bridge between the ancient and modern worlds of beauty. It has a number of impressive skin and hair benefits and is well-tolerated by most people. You can easily add it to your routine through ready-made products or by making your own. So keep this powerhouse ingredient in mind, whether you want to hydrate and protect your skin or revive dry, damaged hair.
