Lavender oil, with its soothing fragrance and purported therapeutic properties, has become a staple in many aromatherapy and wellness routines. Its applications range from stress relief and sleep improvement to skincare and hair care. A common question that arises, particularly for those concerned with unwanted hair, is: does lavender oil actually stop hair growth? The answer, as with many natural remedies, is nuanced and requires a closer look at the available evidence.
Unpacking the Claims: Lavender Oil and Hair Growth
The idea that lavender oil might inhibit hair growth likely stems from observations about its potential hormonal effects and its documented anti-inflammatory properties. To understand this better, let’s explore each angle separately.
The Hormonal Connection
Hormones play a crucial role in hair growth cycles. Androgens, such as testosterone and dihydrotestosterone (DHT), are particularly influential, especially in conditions like androgenetic alopecia (male and female pattern baldness). Some believe that lavender oil might influence hormone levels, potentially impacting hair growth. However, research on this specific effect is limited and inconclusive.
The evidence suggesting a hormonal link comes primarily from studies looking at the effects of lavender oil on other hormone-related conditions, such as gynecomastia (breast enlargement in males) in prepubertal boys. These studies, though relatively rare, have suggested that lavender oil might have estrogenic (estrogen-like) effects or anti-androgenic (androgen-blocking) effects. If lavender oil were indeed anti-androgenic, theoretically, it could potentially reduce hair growth in areas where androgen hormones stimulate it, such as the face or body.
However, it’s critical to note that these studies are not directly related to hair growth inhibition and involve different populations and dosages than typically used in aromatherapy or topical applications. Furthermore, any hormonal effect of lavender oil is likely to be very mild compared to pharmaceutical hormone therapies.
Anti-Inflammatory Properties and Hair Follicles
Inflammation around hair follicles can disrupt the normal hair growth cycle, leading to hair loss or slowed growth. Conditions like folliculitis, psoriasis, and eczema can cause inflammation that affects hair follicles. Lavender oil is known for its anti-inflammatory properties, attributed to compounds like linalool and linalyl acetate.
By reducing inflammation, lavender oil might, in some cases, promote a healthier scalp environment that supports healthy hair growth. However, this is quite different from inhibiting hair growth. In fact, by reducing inflammation, it might even promote hair growth in areas where inflammation was hindering it.
Research on Lavender Oil and Hair Growth: What Does the Science Say?
While anecdotal evidence abounds regarding the benefits of lavender oil for hair, scientific research directly addressing its ability to stop hair growth is scarce. Most studies focus on the positive effects of lavender oil on hair growth, rather than its potential to inhibit it.
Studies on Hair Growth Promotion
Several studies have explored the potential of lavender oil to stimulate hair growth, particularly in the context of alopecia areata (an autoimmune condition that causes hair loss). These studies often involve animal models or small human trials.
For example, some research has shown that topical application of lavender oil can increase the number of hair follicles, deepen follicle depth, and thicken the dermal layer in mice. These findings suggest that lavender oil might stimulate hair growth, potentially by improving blood circulation to the hair follicles or by possessing antioxidant properties that protect hair follicles from damage.
These findings contradict the idea that lavender oil inhibits hair growth. However, it’s essential to recognize that results from animal studies may not always translate directly to humans.
Lack of Evidence for Hair Growth Inhibition
The lack of scientific studies supporting the claim that lavender oil inhibits hair growth is significant. There is no strong evidence to suggest that topical application of lavender oil will effectively stop or slow down hair growth in unwanted areas.
Existing research primarily focuses on its potential benefits for hair growth, scalp health, and overall well-being. While the hormonal effects of lavender oil remain a topic of interest, the current evidence does not support the idea that it can significantly alter hormone levels in a way that would inhibit hair growth.
How Lavender Oil is Typically Used in Hair Care
Lavender oil is widely incorporated into hair care products and routines for its potential benefits, which primarily focus on promoting hair health and relaxation.
Common Uses and Benefits
- Scalp Health: Lavender oil’s anti-inflammatory and antimicrobial properties may help soothe scalp irritation, reduce dandruff, and improve overall scalp health.
- Hair Strengthening: Some believe that lavender oil can strengthen hair strands, making them less prone to breakage and split ends.
- Stress Reduction: The aroma of lavender oil is known for its calming and relaxing effects, which can indirectly benefit hair health by reducing stress levels, a known contributor to hair loss.
- Improved Blood Circulation: Massaging lavender oil into the scalp may help improve blood circulation to the hair follicles, potentially promoting hair growth.
Methods of Application
Lavender oil is typically used in hair care in the following ways:
- Diluted Topical Application: A few drops of lavender oil are mixed with a carrier oil, such as coconut oil, jojoba oil, or almond oil, and massaged into the scalp.
- Addition to Hair Products: Lavender oil can be added to shampoos, conditioners, or hair masks.
- Aromatherapy: Inhaling lavender oil through a diffuser or direct inhalation can promote relaxation and reduce stress, indirectly benefiting hair health.
Considering the Risks and Side Effects
While lavender oil is generally considered safe for topical use, it’s essential to be aware of potential risks and side effects.
Potential Side Effects
- Skin Irritation: Some individuals may experience skin irritation or allergic reactions to lavender oil, especially if applied undiluted.
- Hormonal Disruption: As mentioned earlier, there is some concern about the potential hormonal effects of lavender oil, particularly with frequent or prolonged use. However, this is still a topic of ongoing research.
Precautions
- Dilution is Key: Always dilute lavender oil with a carrier oil before applying it to the skin or scalp.
- Patch Test: Perform a patch test on a small area of skin to check for any allergic reactions before applying lavender oil more broadly.
- Pregnancy and Breastfeeding: Pregnant or breastfeeding women should consult with their healthcare provider before using lavender oil.
- Children: Exercise caution when using lavender oil on children, especially young children, due to the potential hormonal effects.
Alternatives for Hair Growth Inhibition
If you are looking for effective ways to inhibit hair growth in unwanted areas, lavender oil is unlikely to be the solution. Several proven methods are available, ranging from temporary to more permanent options.
Temporary Methods
- Shaving: A quick and easy method, but the hair grows back quickly.
- Waxing: Removes hair from the root, providing longer-lasting results than shaving.
- Sugaring: Similar to waxing but often considered gentler on the skin.
- Depilatory Creams: Chemical creams that dissolve hair at the skin surface.
- Threading: A technique using thread to remove hair from the follicles.
More Permanent Methods
- Laser Hair Removal: Uses laser light to destroy hair follicles, leading to long-term hair reduction.
- Electrolysis: Uses electrical currents to destroy hair follicles, offering a more permanent solution.
- Prescription Creams: Eflornithine (Vaniqa) is a prescription cream that can slow down facial hair growth in women.
Conclusion: Lavender Oil and Hair Growth – A Summary
In conclusion, the claim that lavender oil stops hair growth is not supported by scientific evidence. While lavender oil offers several potential benefits for hair health, such as reducing inflammation, promoting scalp health, and reducing stress, there is no indication that it can effectively inhibit hair growth in unwanted areas. Research primarily focuses on its potential to stimulate hair growth, not prevent it.
If you are seeking ways to inhibit hair growth, it is best to explore proven methods like waxing, laser hair removal, or electrolysis. While lavender oil can be a valuable addition to your hair care routine for promoting overall hair health and well-being, it is not a suitable solution for unwanted hair.

Can lavender oil directly stop hair growth on the scalp?
While some studies explore lavender oil’s potential effects on hair, the consensus isn’t that it stops hair growth. Most research focuses on promoting hair growth or improving scalp health, rather than inhibiting follicle activity. There’s no scientific evidence to definitively suggest that lavender oil contains compounds that directly halt the cellular processes responsible for hair production.
It’s more accurate to say that lavender oil’s calming and anti-inflammatory properties might indirectly affect hair growth. By reducing stress or inflammation on the scalp, which can sometimes hinder hair growth, lavender oil could potentially create a more favorable environment for follicles. However, this is more about fostering healthy growth conditions than actively stopping the hair growth process.
Is there any evidence suggesting lavender oil slows down hair growth on other body parts?
There is very little scientific evidence to suggest that lavender oil slows down hair growth on any part of the body, including areas outside the scalp. The primary research areas involve its potential benefits for hair growth, scalp health, and stress reduction, rather than its ability to inhibit hair production. Claims of slowed hair growth are likely anecdotal and lack robust scientific backing.
It’s important to consider that hair growth rates and characteristics vary significantly based on genetics, hormonal factors, and overall health. Any perceived slowing of hair growth after using lavender oil might be coincidental or related to other factors. More research would be needed to explore any potential relationship between lavender oil and hair growth rates on different body areas, but currently, no studies support this idea.
Does the concentration of lavender oil affect its impact on hair growth?
Yes, the concentration of lavender oil likely plays a significant role in its effect on hair growth. Most studies investigating lavender oil’s benefits for hair utilize diluted forms, typically mixed with a carrier oil. Concentrated, undiluted lavender oil could potentially cause skin irritation or sensitivity in some individuals, which could, in turn, indirectly impact hair growth.
Higher concentrations don’t necessarily translate to better results. Using properly diluted lavender oil allows for safe application and absorption, potentially maximizing its intended benefits for scalp health and hair follicles. It’s crucial to follow recommended dilution guidelines to avoid adverse reactions and ensure optimal effectiveness.
Can lavender oil help with conditions that inhibit hair growth, like alopecia?
Some studies suggest that lavender oil may offer potential benefits in managing conditions like alopecia, particularly alopecia areata, an autoimmune disorder that causes hair loss. Lavender oil’s anti-inflammatory and antioxidant properties might help to soothe the scalp and promote hair regrowth in some individuals experiencing hair loss due to inflammatory conditions.
However, it is important to note that lavender oil is not a cure for alopecia or other hair loss conditions. While it may help to improve scalp health and stimulate hair follicles, it should be used as a complementary treatment alongside other medical interventions prescribed by a dermatologist or healthcare professional. More research is needed to fully understand the effectiveness of lavender oil in treating specific types of hair loss.
Are there any side effects associated with using lavender oil on the scalp?
While lavender oil is generally considered safe for topical use, some individuals may experience side effects, particularly if they have sensitive skin. Common side effects include skin irritation, redness, itching, or a burning sensation. Allergic reactions to lavender oil are also possible, although less common.
To minimize the risk of side effects, it is essential to perform a patch test before applying lavender oil to a larger area of the scalp. Diluting lavender oil with a carrier oil, such as coconut oil or jojoba oil, can also help to reduce the likelihood of skin irritation. If you experience any adverse reactions, discontinue use and consult a healthcare professional.
Can I use lavender oil to remove unwanted hair from my body?
No, there is no scientific evidence to support the claim that lavender oil can be used to remove unwanted hair from the body. Lavender oil primarily is studied for its potential to promote hair growth or improve scalp health, rather than its ability to inhibit or remove hair follicles.
Effective methods for removing unwanted hair typically involve techniques that target the hair follicle itself, such as waxing, shaving, laser hair removal, or electrolysis. Lavender oil does not possess the properties necessary to disrupt or destroy the hair follicle in a way that would result in hair removal.
Is lavender oil safe to use on children’s hair?
Lavender oil is generally considered safe for topical use on children’s hair when properly diluted and used with caution. However, it is important to exercise extra care when using essential oils on children, as their skin is more sensitive and susceptible to irritation than adult skin.
Always dilute lavender oil with a carrier oil, such as coconut oil or almond oil, to minimize the risk of skin irritation. Start with a very low concentration and perform a patch test on a small area of the child’s skin before applying it to their scalp or hair. If you have any concerns, consult with a pediatrician or aromatherapist before using lavender oil on your child’s hair.
