Introduction 

Have you ever explored natural ingredients for hair health? Peppermint oil is a commonly recommended remedy. It’s an essential oil obtained from the peppermint plant. It’s been used for a variety of reasons for years. Of course, we’re here to talk about hair! So, what does science say? We’ll take a look at what research shows about the benefits of peppermint oil for hair and scalp. Plus, we’ll give you tips on adding it to your hair routine.

All About Peppermint Oil 

In a nutshell, peppermint essential oil is just the peppermint plant packed into a potent, beneficial bottle. It is widely used in beauty products and may have great health benefits too. Its main ingredient is menthol. You’ll love its aroma, flavour, and cooling touch. 


Why Use Peppermint Oil for Hair? 

1. Supporting Hair Growth 

Peppermint oil can boost blood flow to the scalp. This feeds your hair roots and may aid in hair growth! Plus, menthol gives a cool, refreshing feel when applied. 

A mouse study showed that a 3% peppermint oil combo did better than an FDA-approved hair growth drug (minoxidil) when it came to hair growth. The peppermint solution made their hair grow thicker and faster. 

2. Improving Scalp Health 

Studies have shown that peppermint oil has some great benefits for your scalp too. 

Peppermint oil has antimicrobial properties and can help fight against fungi, and inflammation, which can aid in keeping a healthy, problem-free scalp. 

Peppermint oil may also help fight dandruff by removing excess oil and build up from the scalp. The cooling sensation from the menthol in peppermint oil can provide a soothing feel and possibly help ease itchy scalp.  

3. Enhancing Your Hair’s Look 

Adding peppermint oil to your hair care routine might aid in boosting its look and shine, making it appear healthier and more vibrant. 

Many studies have found beneficial properties of peppermint oil for hair health, however, large-scale human studies are needed to confirm their benefits.

How to Use Peppermint Oil for Hair Care? 

Now, let’s talk about how to use this oil. 

1. Mixing with Carrier Oils 

Before applying peppermint oil to your scalp, you need to mix it with a carrier oil. This reduces the risk of skin irritation. Sounds good, right? Common carrier oils are coconut, jojoba and castor oil. 

2. Picking the Best Carrier Oil 

Does your hair have specific needs? Choose a suitable carrier oil. If your skin is oily or acne-prone, you may try non-pore-blocking oils like jojoba. 

  • Mix It in Shampoo and Conditioner 

You can add peppermint oil to your regular shampoo and conditioner. A quick guide; just add 4-5 drops of the oil to every ounce of shampoo or conditioner. 

  • Getting the Measurements Right 

Don’t go overboard adding peppermint oil to your shampoo or conditioner. Overdoing it could cause discomfort. Go with the suggested 4-5 drops per ounce. 

3. Using Peppermint Oil for Scalp Massage 

A scalp massage using diluted peppermint oil may help in boosting blood flow to the scalp. Just combine the oil with a carrier oil and rub it gently into your scalp. It feels amazing! 

  • Nailing the Technique 

To get the best results, leave the oil on your scalp for 15-20 minutes before washing your hair. If you feel too much tingling, add more carrier oil to mellow it out or wash your hair right away. 

4. Incorporating in Hair Masks and Treatments 

Throwing peppermint oil into DIY hair masks can do wonders for your hair. Use natural ingredients like honey, egg, yogurt, or avocado, and of course, a dash of peppermint oil. 

Apart from its effects on dryness, itching or other scalp problems, peppermint oil can improve hair growth if applied regularly along with other oils like Jojoba oil or shea butter oil directly on the scalp to see visible results only after a continuous period of 4-8 weeks.

Try These DIY Recipes 

Here are some DIY hair mask ideas using peppermint oil: 

  1. Peppermint Oil plus Honey: Mix two spoons of honey with 5-6 drops of oil. Apply this combo to your hair and scalp. Leave for half an hour. Wash off with your regular shampoo. 
  2. Blend Avocado, Egg and Peppermint Oil: Mash a ripe avocado, beat an egg and mix. Add 10-12 drops of oil to this mixture. Apply on hair and scalp, rinse off after 30 minutes with your usual shampoo. 

Even though essential oils can be useful in promoting hair and scalp health, it is best to consult your dermatologist before using any new therapy for hair loss or scalp issues as these may be caused by more serious underlying conditions. 

Results suggest that peppermint oil induces a rapid anagen stage and could be used for a practical agent for hair growth without change of body weight gain and food efficiency.

Risks and Possible Allergic Reactions 

Peppermint oil can cause issues when used undiluted. Always mix it with a carrier oil first. It is best to do a patch test before actually using this oil. 

Try rubbing out a small dab of diluted peppermint oil on a hidden piece of skin (like your wrist inside). Wait at least 24 hours to see if anything happens, like redness, itching, or swelling. If any sign shows up, stop using it and talk to your healthcare provider. 

The Correct Amount and Proper Application 

Remember to use just 4-5 drops of peppermint oil for each ounce of carrier oil, shampoo, or conditioner. This holds the risk of irritation down. 

Even though topical use of peppermint oil is generally okay for most individuals, pregnant or nursing women should consult their healthcare provider before using it.

2. Lavender Oil
