Does Olive Oil Help Hair Grow? Uncover the Benefits
Olive oil, usually light yellow or green, is naturally extracted by pressing olives and is often imported from Mediterranean countries like Spain, Greece, and Italy. It’s rich in fatty acids and antioxidants, and its unique chemical composition has been appreciated for centuries by various cultures for enhancing hair texture and appearance.
Can olive oil help hair grow? Research suggests that olive oil can soothe the scalp, strengthen hair follicles, and potentially stimulate hair growth. In this review, we explore the evidence supporting the use of olive oil for achieving stronger, longer hair.
Does Olive Oil Help Hair Grow?
Currently, no human clinical trials have confirmed the effectiveness of olive oil in promoting hair growth or preventing hair loss. Evidence comes from a small study on mice, which showed increased hair growth after being treated with topical oleuropein, a compound found in olives and olive leaves. However, several factors limit the applicability of this study to human hair:
- Olive oil contains lower amounts of oleuropein compared to olives or olive leaves.
- Mouse skin and hair differ significantly from human scalp and hair.
- The time required to naturally absorb enough oleuropein through the scalp from topically applied olive oil might be impractically long.
Therefore, until further research is conducted, the only proven benefit of olive oil for thinning hair is its ability to moisturize and prevent hair breakage, thanks to its high fatty acid content.
Other Benefits of Olive Oil for Hair
While olive oil may not have proven benefits for hair growth at this time, it does offer properties that can benefit your hair and scalp. However, most of these benefits still require further research to confirm their effectiveness under various conditions:
Antioxidant Properties
Excessive exposure to sunlight can damage your hair and scalp due to UV radiation. Olive oil contains natural antioxidants that may reduce oxidative stress and prevent some UV damage to your hair. One study on mice found that using olive oil topically after UV exposure reduced the number of skin tumors developed. However, using olive oil preventively, before UV exposure, did not have the same effect. Although there are no human clinical studies to confirm this, it suggests potential protective benefits.
Anti-inflammatory Properties
Olive oil contains phenols that possess anti-inflammatory qualities similar to Ibuprofen. When ingested, olive oil is known to have anti-inflammatory properties. However, there is no conclusive evidence that it has the same effect when applied topically. Further research is needed to determine if olive oil can soothe inflammation, irritation, or tenderness on the scalp.
Antimicrobial Properties
Olive oil has demonstrated antimicrobial qualities in vitro, including antifungal properties. One in vitro study found it effective against candida, reducing it by 50%. This suggests that olive oil could help prevent or treat yeast infections on the scalp, such as dandruff or seborrheic dermatitis. However, more research is needed to determine if it is effective when applied to the human scalp. Some medical professionals believe that olive oil may exacerbate dandruff and seborrheic dermatitis by feeding the yeast that causes them.
Moisturizing and Softening Properties
The abundant fatty acids in olive oil are excellent emollients, softening and moisturizing your hair and scalp. They coat your strands in a protective layer that prevents friction-induced breakage or split ends. Additionally, olive oil can seal the hair cuticle, keeping moisture inside for longer.
Potential Side Effects of Olive Oil
Olive oil is generally safe for human consumption and can be used topically on your scalp and hair. It is not known to cause significant irritation or other types of skin damage. While allergic reactions can occur, they are generally rare and mild.
However, due to its high fatty acid content, excessive use of olive oil on your scalp and hair can lead to greasiness and clogged pores, potentially causing scalp acne or folliculitis. Therefore, it’s best to avoid using this type of oil if you already have greasy hair. Always ensure you wash your scalp thoroughly with shampoo after using olive oil for your hair.
How to Use Olive Oil for Hair
There are several ways to incorporate olive oil into your hair care routine. While its effectiveness in promoting hair growth has not been proven, olive oil can soften, moisturize, and condition your strands, especially if you have dry, brittle hair:
Scalp Massage:
- Pour a few drops of olive oil into your hands.
- Gently massage your scalp with the oil.
- Use a fine-toothed comb to spread the oil evenly along the length of your hair.
- Be cautious, as the oil can stain clothes or furniture. To prevent stains, wrap your hair in a towel or wear a shower cap.
Hair Mask:
- Mix olive oil with other essential oils, such as rosemary or peppermint oil.
- Apply the mixture to your hair as a mask.
- Leave it on for 30 minutes before washing it out thoroughly.
Split Ends Treatment:
- Apply olive oil only to your split ends, avoiding the scalp and the rest of your hair.
- Use a comb to distribute the oil.
- Leave it on for as long as necessary before washing it out. This method helps prevent your scalp from becoming greasy while conditioning your ends.
Notes:
- For a deep conditioning treatment, apply warm olive oil to your hair, cover with a shower cap, and leave it on for at least 30 minutes before rinsing.
- For added benefits, mix olive oil with honey or yogurt to create a nourishing hair mask.
- Always rinse your hair thoroughly after using olive oil to avoid buildup and greasiness.
Can You Put Olive Oil Directly in Your Hair?
Yes, you can apply pure olive oil directly to your hair without diluting it first, as it is unlikely to cause irritation or burns on your scalp. Olive oil can also be used as a carrier oil, allowing you to dilute other essential oils for added benefits.
Notes:
– When applying olive oil directly, start with a small amount to avoid excessive greasiness.
– For a more intensive treatment, warm the olive oil slightly before applying it to your hair.
– Combining olive oil with essential oils like lavender or tea tree can provide additional benefits, such as soothing the scalp and promoting overall hair health.
Who Should Use Olive Oil?
Olive oil is particularly beneficial for individuals with curly, thick, and coarse hair prone to frizz and dryness. It aids in moisturizing and softening these hair types, enhancing manageability and minimizing frizz. However, applying olive oil to fine or straight hair may lead to a weighed-down, greasy feel.
Moreover, if you have dandruff, it’s advisable to refrain from using olive oil in your hair, as it could worsen the condition.
Conclusion
Does olive oil help hair grow? While there’s some suggestion that olive oil may promote healthy hair growth, scientific evidence remains inconclusive. Olive oil contains proteins, antioxidants, and antimicrobial agents that could potentially contribute to overall hair health.
Regular use of olive oil might help strengthen hair follicles and prolong the lifespan of each hair, giving the appearance of faster growth.
Ultimately, olive oil offers a cost-effective alternative for hair care, and experimenting with it poses no harm.
