Waiting for your hair to grow is like watching paint dry—except worse. With paint you know for certain it'll dry in, well, approximately a few hours. Hair on the other hand—depending on the damage and length—could take months (if not years) to grow to your desired length. Of course, there are products you can apply to speed up the process (think hair masks, treatments, serums, and the like), but how quickly those work is up for debate. Not to mention some hair products can actually coat the hair and cause more damage than assist with growing out your locks. Don't freak out just yet—turns out essential oils, (yes, the ones you put on your skin) can get the job done...much quicker.


When it comes to cedarwood, it's all about the scalp. The way that cedarwood essential oil contributes to hair growth is by keeping your scalp healthy and happy. It stimulates the scalp and increases circulation, thus reducing a dry or flaky scalp and brittle hair. It also helps in balancing the oil-producing glands in the scalp, which can lead to healthier strands, it also has antifungal and antibacterial properties, which can treat different conditions that may contribute to dandruff or hair loss.


 Rosemary essential oil is the first essential oil that comes to mind when thinking about ways to improve hair growth and strength. It stimulates hair growth by dilating the blood vessels and promoting cell division in the scalp, thus delivering the nutrients and oxygen needed for follicles to grow. And if you have dry scalp, rosemary's anti-inflammatory properties help to keep hair follicles healthy and dandruff at bay.


A gorgeous sight to see (seriously, the star shape is magical), the ylang-ylang flower is more than just a base for perfumes. Ylang-ylang oil balances oil on the scalp, strengthens the hair follicles, and conditions the scalp. It works well for a dry scalp as it’s a natural conditioner, and also helps to stimulate the sebaceous glands, which keeps the hair naturally moisturized. And because it has antiseptic properties, it can be used as a hair treatment for other hair conditioners, namely lice. Because it's antiseptic, it can help get rid of lice—as well as other fungal infections—when mixed with a carrier oil.


Bergamot is touted in the essential oil world for its aromatherapy benefits, but it's also seriously helpful in getting rid of microbes in the hair. All those nasty chemicals from your haircare and styling products along with dandruff, dirt, and excess sebum cause build-up and irritation on the scalp as well as clog the follicles. It causes extreme damage to the hair follicles and prevents the natural growth of hair by resulting in a number of scalp issues like infections, acne, and eczema.

However, being a great natural antimicrobial agent, bergamot essential oil inhibits the growth of bacteria—thus, the scalp remains clean, healthy, and absolutely perfect for hair growth." Apart from eradicating microbes and averting the possibilities of developing scalp infections, the beauty of bergamot is that it works on already-infected scalps and actually stops the contagion from getting worse. This is very much important for the health and growth of the locks, as this accelerates the growth of hair, makes it stronger and keeps split ends away Heads up: Bergamot may make the skin more sensitive to the sun, so be sure to avoid sunlight for 12 hours after using it on your skin.


Lavender essential oil has antimicrobial properties similar to those found in tea tree, but with a more gentle effect on the skin when applied topically.  Beyond keeping hair shafts and follicles clear of bacteria (that could prevent hair growth), another added benefit of using lavender essential oil is its ability to soothe your scalp (and your mind) courtesy of its natural sedative properties. People say your hair thins when you're stressed—so prevent the feeling of stress by adding a few drops to your dry shampoo or conditioner.

Lavender can also be helpful for other hair issues like hair loss, thinning, breakage, dryness, and dandruff, but that it isn't usually recommended if you take nervous system sedatives or depressants because the interaction with these medications may exaggerate sleepiness or drowsiness.

Tea Tree 

We know and love tea tree oil for its ability to heal breakouts, but it can also work wonders for the health of our hair, too. Tea tree essential oil has powerful cleansing, antibacterial, and antimicrobial properties, which is why it's commonly found in scalp-healthy hair products to fend off dandruff. If left untreated, dandruff can absolutely lead to hair loss. As the flakes build up on the scalp and mix with the natural oils produced by our skin, the thick, waxy substance can irritate the scalp and even clog hair follicles. While there are reports that tea tree oil can help regulate overactive sebaceous glands, there is no definitive data that shows tea tree oil can actually penetrate into the follicle and dissolve the debris inside.

Clary Sage 

Clary sage oil, different from regular sage oil, is thought to be a superstar for improving overall hair health. It contains linalool, linalyl acetate, alpha-terpineol, germacrene D, and geranyl, and has been used for years in the management of hormonal disturbances in women. Recently, it is also being praised for its ability to regulate cortisol levels (a stress hormone that is produced by the body in excess during times of physical and emotional stress), which can be an underlying cause of hair loss.


Here's an oil that's ideal for those with oilier hair types (dry scalp and brittle hair should steer clear). Peppermint oil helps to stimulate your scalp and hair follicles, and also stimulates blood circulation to the skin, which can help with increasing dermal thickness, follicle number, and follicle depth. Research has shown that menthol has the potential to dilate the blood vessels beneath the skin where it is applied, increasing blood flow to the area.  Increased blood flow to the scalp is good because blood carries oxygen and nutrients, which at the very least can improve the health of the hair follicles, and ultimately help in terms of hair growth.


Thyme oil is a nutrient-rich oil containing bioflavonoids and antioxidants, and it also has anti-inflammatory and antimicrobial properties.  However, it’s the bioflavonoids, specifically, that have brought much recent attention to thyme oil and its ability to promote hair growth, as they have been shown to play an important role in the formation of new hair strands.  Generally speaking, reducing inflammation on the scalp and hair follicles makes for an overall healthier scalp and ultimately a healthier environment for hair to grow.


Turns out lemongrass isn't just a hero ingredient in your favorite Thai soup, it boasts a slew of hair-loving properties that induce growth. Lemongrass oil can strengthen your hair follicles, and it's great for those with dandruff. And if you're keen on not over-shampooing your hair, lemongrass oil has astringent properties that can help keep the hair squeaky clean in between washes.
