A couple of years ago, I was dealing with an itchy, irritated scalp that just wouldn’t quit. No matter how many shampoos I tried, the redness and flakiness kept coming back, and it was starting to mess with my confidence. Then I stumbled across licorice extract—not the candy, but the powerful root used for centuries in herbal medicine. This natural gem turned out to be a game-changer for soothing my scalp and restoring its health. Through my own experiments, research, and a bit of trial and error, I’ve learned how licorice extract can calm an irritated scalp and even support hair health. If you’re struggling with itchiness, redness, or flaking, let’s dive into why licorice extract is a must-try, how it works, and practical ways to use it at home.
What Is Licorice Extract?
Licorice extract comes from the root of the Glycyrrhiza glabra plant, a staple in traditional medicine across cultures like Ayurveda, Traditional Chinese Medicine, and ancient Egyptian healing. It’s packed with bioactive compounds like glycyrrhizin, glabridin, and flavonoids, which have anti-inflammatory, antimicrobial, and antioxidant properties. These make it a powerhouse for calming scalp irritation and reducing conditions like dandruff or seborrheic dermatitis.
I first came across licorice extract in a natural hair care forum, and I was skeptical—could something I associated with candy really help my scalp? But studies, like one from the Journal of Ethnopharmacology (2013), show that licorice’s anti-inflammatory effects can soothe skin conditions, including scalp issues. After trying it, I was amazed at how it calmed my itchiness. Let’s explore why it’s so effective for your scalp.
Why Licorice Extract Works for Scalp Health
Your scalp is like the soil for your hair—when it’s irritated, your hair suffers. Inflammation, often caused by an overgrowth of yeast like Malassezia, stress, or harsh products, can lead to redness, itching, and flaking. This not only feels uncomfortable but can weaken hair follicles, causing shedding or slow growth. A 2014 study in the Journal of Investigative Dermatology linked scalp inflammation to hair loss, which hit home for me when I noticed thinning during my scalp flare-ups.
Licorice extract tackles these issues in several ways:
Anti-Inflammatory: Glycyrrhizin reduces redness and swelling, calming irritated scalps.
Antimicrobial: It fights Malassezia and bacteria that cause dandruff and folliculitis.
Antioxidant: Flavonoids protect against oxidative stress, which can damage follicles and accelerate aging.
Soothing: It reduces itching and sensitivity, creating a healthier scalp environment.
I started using licorice extract when my scalp was red and flaky, and within weeks, the itching eased, and my hair felt stronger. Here’s how you can use it to calm your scalp naturally.
How Licorice Extract Calms Your Scalp
Licorice extract’s magic lies in its ability to target the root causes of scalp irritation. Here’s a breakdown of its benefits, based on science and my experience:
1. Reduces Inflammation
Glycyrrhizin, a key compound in licorice, mimics cortisol to reduce inflammation. A 2010 study in Phytotherapy Research found that licorice extract soothes inflammatory skin conditions like eczema, which translates to scalp relief. My scalp’s redness faded after regular use.
2. Fights Yeast and Bacteria
Malassezia yeast is a common culprit behind dandruff and seborrheic dermatitis. Licorice’s antimicrobial properties, noted in a 2012 Fitoterapia study, help control yeast overgrowth, reducing flaking. This was a lifesaver when my dandruff was at its worst.
3. Protects Against Oxidative Stress
Free radicals from pollution or UV rays can inflame the scalp and weaken follicles. Licorice’s antioxidants, like glabridin, neutralize these, per a 2015 Journal of Cosmetic Science study. This helped my scalp feel less sensitive to environmental stressors.
4. Balances Scalp pH
An imbalanced scalp pH can lead to irritation and flaking. Licorice’s gentle properties help maintain a healthy pH, supporting the scalp’s microbiome. A 2018 International Journal of Trichology study emphasized the importance of a balanced microbiome for scalp health.
5. Promotes Hair Health
By calming inflammation, licorice creates a better environment for hair growth. It reduces follicle stress, which can prevent shedding. I noticed less hair in my brush after incorporating licorice into my routine.
Natural Ways to Use Licorice Extract for Your Scalp
Here are the methods I’ve used to incorporate licorice extract, along with tips to make them effective. These are natural, affordable, and backed by science or tradition.
1. Licorice Root Tea Rinse
Licorice root tea is an easy way to deliver its soothing benefits to your scalp. It’s gentle and great for regular use.
How to Make It:
Boil 2 tbsp dried licorice root in 2 cups water for 10 minutes.
Cool, strain, and pour into a spray bottle.
After shampooing, spray or pour over scalp, massage for 2 minutes, and rinse. Use twice a week.
My Experience: This rinse reduced my scalp’s itchiness after the first use. After a month, flaking was minimal, and my hair felt softer.
Tip: Use organic licorice root to avoid additives. Test for sensitivity first.
2. Licorice and Coconut Oil Scalp Treatment
Coconut oil hydrates and enhances licorice’s anti-inflammatory effects. A 2003 Journal of Cosmetic Science study praised coconut oil for reducing scalp dryness.
How to Make It:
Mix 1 tsp licorice extract (liquid form, available at health stores) with 2 tbsp virgin coconut oil.
Massage into scalp, leave for 30 minutes, and shampoo thoroughly. Use weekly.
My Experience: This calmed my red, flaky scalp and left my hair shinier. It’s now a weekly staple.
Tip: Warm the oil slightly for better absorption, but don’t overheat.
3. Licorice and Aloe Vera Mask
Aloe vera’s soothing enzymes pair perfectly with licorice to reduce irritation. A 2010 Journal of Chemical and Pharmaceutical Research study noted aloe’s benefits for scalp health.
How to Make It:
Mix 2 tbsp fresh aloe vera gel with 1 tsp licorice extract.
Apply to scalp, leave for 20 minutes, and rinse. Use weekly.
My Experience: This mask instantly soothed my itchy scalp. After three weeks, redness was gone, and my scalp felt balanced.
Tip: Use fresh aloe for maximum potency, but store-bought organic gel works too.
4. Licorice-Infused Shampoo
Adding licorice extract to your shampoo is a low-effort way to calm your scalp daily.
How to Use:
Add 5–10 drops of licorice extract to a 4 oz bottle of sulfate-free shampoo.
Shake well and use as your regular shampoo, massaging into scalp for 1–2 minutes.
My Experience: My scalp felt less irritated after a week, and flaking reduced significantly by month two.
Tip: Choose a gentle, fragrance-free shampoo to avoid irritation.
5. Licorice and Green Tea Rinse
Green tea’s antioxidants complement licorice’s anti-inflammatory effects, reducing scalp redness. A 2005 Phytomedicine study highlighted green tea’s role in calming inflammation.
How to Make It:

Pour over scalp after shampooing, massage, and rinse after 5 minutes. Use twice a week.
My Experience: This rinse reduced oiliness and flaking, leaving my scalp refreshed. My hair also had a subtle shine.
Tip: Use organic green tea for purity.
6. Scalp Massage with Licorice Oil
Massaging boosts circulation, helping licorice’s compounds reach follicles. A 2016 Eplasty study showed massages increase hair thickness by improving blood flow.
How to Do It:
Mix 1 tsp licorice extract with 1 tbsp jojoba oil (mimics scalp sebum).
Massage into scalp for 5–10 minutes daily, leave for 20 minutes, and rinse.
My Experience: This reduced my scalp’s tightness and itching. New hair growth appeared after six weeks.
Tip: Use a scalp massager for ease and deeper stimulation.

Chamomile’s soothing properties enhance licorice’s calming effects, reducing redness and flaking.
How to Make It:
Brew 1 tbsp dried licorice root and 2 chamomile tea bags in 2 cups hot water, cool, and strain.
Pour over scalp, massage, and rinse after 5 minutes. Use twice a week.
My Experience: This rinse soothed my scalp and added shine to my hair. Flakes were nearly gone after a month.
Tip: Add a drop of lavender oil for extra relaxation.
9. Avoid Harsh Products
Harsh shampoos or styling products can inflame the scalp. I switched to gentle care to support licorice’s effects.
How to Do It:
Use sulfate-free, fragrance-free shampoos.
Avoid alcohol-based products or heavy gels.
Limit heat styling; air-dry when possible.
My Experience: Ditching my sulfate shampoo reduced irritation, letting licorice work better.
Tip: Check labels for irritants like sodium lauryl sulfate.
10. Stress Management
Stress spikes cortisol, worsening scalp inflammation. A 2018 Journal of Cosmetic Dermatology study linked stress to hair and scalp issues.
How to Do It:
Practice 10 minutes of meditation or deep breathing daily.
Try yoga or a short walk to reduce stress.
My Experience: Adding meditation helped me manage flare-ups, especially during busy weeks.
Tip: Use a meditation app to stay consistent.
DIY Licorice Scalp Recipes
Here are two of my favorite recipes:
Soothing Licorice Scalp Mask
Ingredients: 1 tsp licorice extract, 2 tbsp aloe vera gel, 1 tbsp coconut oil.
Instructions: Mix, apply to scalp, leave for 20 minutes, and rinse. Use weekly.
Result: Calms redness and reduces flakes. My scalp felt soothed after one use.

Common Mistakes to Avoid
I’ve made plenty of slip-ups, so here’s what to watch out for:
Overusing Licorice: Too much extract irritated my scalp once. Stick to recommended amounts.
Skipping Dilution: Undiluted licorice extract can sting. Always mix with a carrier like oil or water.
Harsh Cleansing: Overwashing stripped my scalp, worsening flaking. Use gentle shampoos.
Ignoring Diet: Topical remedies alone didn’t cut it until I ate anti-inflammatory foods.
The Science Behind Licorice Extract
Licorice extract works because:
Glycyrrhizin: Reduces inflammation by mimicking cortisol (Phytotherapy Research, 2010).
Glabridin: Fights oxidative stress, protecting follicles (Journal of Cosmetic Science, 2015).
Antimicrobial Action: Controls Malassezia and bacteria (Fitoterapia, 2012).
Microbiome Support: Balances scalp pH, reducing irritation (International Journal of Trichology, 2018).
These mechanisms calm the scalp, reduce flaking, and create a healthy environment for hair growth.
My Journey with Licorice Extract
When I started using licorice extract, my scalp was red, itchy, and flaky. I began with a weekly licorice and coconut oil treatment, added a biweekly tea rinse, and ate more omega-3-rich foods. Within three weeks, the itching eased, and flakes were less visible. By month two, my scalp was calm, and my hair looked shinier and fuller. Stress still triggers minor flare-ups, but my routine keeps things under control. I love the soothing ritual of these remedies—it’s become my self-care haven.
When to See a Professional
If your scalp stays inflamed or flaky after 3–4 months, or you notice sores, severe hair loss, or persistent pain, see a dermatologist. Conditions like psoriasis or severe seborrheic dermatitis may need medical treatment. I consulted a dermatologist when my flaking didn’t fully resolve, and they confirmed mild dandruff, which my remedies now manage.
Final Thoughts
Licorice extract is a natural, powerful way to calm an inflamed, flaky scalp. From tea rinses to soothing masks, it tackles redness, itching, and dandruff while supporting hair health. Pair it with a nutrient-rich diet, gentle hair care, and stress management for the best results. Start small—try a licorice rinse or scalp massage—and be consistent. My scalp went from irritated to peaceful, and my hair’s thriving. Yours can too! Grab some licorice extract, mix up a mask, and give your scalp the love it deserves.
