Many hair products contain chemicals that may damage you
hair over time. This article describes the benefits of using olive oil for hair
growth to maintain a healthy head of hair. Different methods of using olive oil
on the hair are detailed as well.
With a variety of ways to style hair these days, it can really
take a beating; whether from a curling iron, straightening iron, or coloring
products. Altering your hair on a regular basis can make you look great, but
can unfortunately take a toll on its quality.
Many hair products contain
chemicals that may damage you hair over time. This is not to say that you
should not experiment with different hairstyles. However, it is beneficial to
know some options for taking proper care of your hair on a regular basis.
The best way to get your hair healthy and strong is by using
a natural method to counteract the effects of any harsh chemicals. There are
various ways to naturally maintain your hair, but one you may already have in
your kitchen cabinet is olive oil.
Benefits of Olive Oil for Hair Growth
The benefits of using olive oil on stressed out hair strands
of the most shocking benefits of olive oil is that it can prevent and even
cure hair loss. When people lose hair, it is due to a hormone responsible
for the shrinkage of the hair follicle shaft. However, the production of
that hormone, called DHT (dihydrotestosterone), is hampered when olive oil
is applied to the scalp.
overall health of the scalp also benefits from olive oil. A healthy scalp
equates to healthy hair. And the natural conditioner properties of olive
oil add moisture to the scalp: an area that people tend to neglect.
healing a scaly and dry scalp; olive oil makes hair soft and shiny. Take a
look at the products in the hair care aisle at your local retailer: many
of them now claim to contain olive oil. This is for good reasons.
oil also has antibacterial properties and antifungal properties that fight
off common scalp and hair problems. Head lice and dandruff are two
examples of conditions that can be either prevented or hampered by the
application of olive oil to the scalp.
How to Use Olive Oil for Hair Growth
Once you know the benefits of using olive oil for healthy
hair growth, you will want to know the easiest way to apply it. The answer is
pour a small amount in your palms and massage it into your scalp, gently,
and continue down to the end of your strands. For approximately a half
hour after your hair is coated, keep your hair wrapped with a damp towel
or shower cap in order to give it time to soak into the scalp and hair
itself. Be sure to wash and condition your hair after the treatment as you
is a simple way to make your own conditioner with olive oil. Try combining
approximately half a cup of olive oil with one egg yolk and a few drops of
lemon juice in a small bowl. Stir well to combine and add the mixture to
your scalp, making sure to get the entire head of hair coated. You may
need more or less depending on the length. Leave the homemade conditioner
in for 15 minutes and simply rinse.
can also use your microwave to make a deep conditioning paste by adding
fragrant honey and cinnamon. Into a microwave-safe bowl, add 1 cup of
olive oil and heat for approximately ten seconds until it is warm: not
hot. Then add approximately ¼ cup of honey and a teaspoon of cinnamon
Combine into a paste and apply to the hair, leaving it on for
fifteen minutes. Rinse with a shampoo to make sure to get rid of any
sticky honey residue. Repeat at least once per week.
With the variety of olive oils on the market, it can be easy
to get confused as to which you should buy for healthy hair growth. It is best
to always purchase extra virgin olive oil, as this type is
processed without the use of chemicals and is in its purest form.
You may also
want to experiment with different types of oil added to the extra virgin olive
oil. Combine equal parts of extra virgin olive oil with sweet almond oil which
helps prevent split ends and improves circulation of the scalp.

Top 5 Benefits Of Olive Oil | Best Health and Beauty Tips | Lifestyle
The phytonutrient in olive oil, oleocanthal, mimics the effect of ibuprofen in reducing inflammation, which can decrease the risk of breast cancer and its recurrence. Squalene and lignans are among the other olive oil components being studied for their possible effects on cancer.
Cure Heart Disease
Olive oil helps lower levels of blood cholesterol leading to heart disease.
Olive oil is rich in antioxidants, especially vitamin E, long thought to minimize cancer risk. Among plant oils, olive oil is the highest in monounsaturated fat, which doesn't oxidize in the body, and it's low in polyunsaturated fat, the kind that does oxidize.
It has been demonstrated that a diet that is rich in olive oil, low in saturated fats, moderately rich in carbohydrates and soluble fiber from fruit, vegetables, pulses and grains is the most effective approach for diabetics. It helps lower "bad" low-density lipoproteins while improving blood sugar control and enhances insulin sensitivity.
Although the reasons are still not fully clear, recent studies have proved that people with diets containing high levels of olive oil are less likely to develop rheumatiod arthritis.
A high consumption of olive oil appears to improve bone mineralization and calcification. It helps calcium absorption and so plays an important role in aiding sufferers and in preventing the onset of Osteoporosis.

Why Extra Virgin Olive Oil is The Healthiest Fat on Earth
Fats in the diet are highly controversial.
You’ll see people arguing about animal fats, seed oils and almost everything in between.
But one of the few fats that most people agree is healthy is extra virgin olive oil.
This oil, part of the Mediterranean diet, is a traditional fat that has been a dietary staple for some of the world’s healthiest populations.
There is actually quite a bit of research behind the health effects of olive oil.
These studies show that the fatty acids and antioxidants in it have some powerful health benefits, such as a reduced risk of heart disease.
What is Olive Oil and How is it Made?
Olive oil is oil that is pressed from olives, the fruits of the olive tree.
The process is incredibly simple… you just press the olives and the oil comes out.
But there is still one major problem with olive oil… it isn’t always what you think it is. Some lower quality versions can be extracted using chemicals, or even diluted with other cheaper oils.
Therefore, buying the right type of olive oil is incredibly important.
The best type is extra virgin olive oil. It is extracted using natural methods and standardized for purity and certain sensory qualities like taste and smell.
Olive oil that is truly extra virgin has a distinctive taste and is high in phenolic antioxidants, the main reason why (real) olive oil is so beneficial.
Then we have regular, refined or “light” olive oils, which have often been extracted with solvents, treated with heat or even diluted with cheaper oils like soybean andcanola oils.
For this reason, the only type I recommend is extra virgin olive oil.
But keep in mind that there is a lot of fraud going on in the olive oil market and it is essential to buy from a reputable seller. Even oil that is labelled as “extra virgin” may have been adulterated with cheaper oils.
If you want to read more about the olive oil fraud and what you can do to find real extra virgin olive oil, read this article.
Bottom Line: Real “extra virgin” olive oil is 100% natural and very high in antioxidants. Many of the lower quality olive oils have been processed and adulterated with cheaper oils.
Nutrient Composition of Extra Virgin Olive Oil
Extra virgin olive oil is fairly nutritious.
It contains modest amounts of Vitamins E and K and plenty of beneficial fatty acids.
This is the nutrient content of 100 grams of olive oil (1):
- Saturated Fat: 13.8%.
- Monounsaturated Fat: 73% (most of it the 18 carbon long oleic acid).
- Omega-6: 9.7%.
- Omega-3: 0.76%.
- Vitamin E: 72% of the RDA.
- Vitamin K: 75% of the RDA.
But where extra virgin olive oil really shines is in its content of antioxidants.
Some of the main antioxidants are the anti-inflammatory oleocanthal, as well asoleuropein, a substance that protects LDL cholesterol from oxidation (4, 5).
Some people have criticized olive oil for having a high Omega-6 to Omega-3 ratio(over 10:1), but keep in mind that the total amount of polyunsaturated fats is still relatively low, so this shouldn’t be a cause for concern.
Bottom Line: Olive oil is very high in monounsaturated fats and contains a modest amount of vitamins E and K. True extra virgin olive oil is loaded with antioxidants, some of which have powerful health benefits.
Extra Virgin Olive Oil Contains Anti-Inflammatory Substances
It is believed that chronic inflammation is among the leading drivers of many diseases.
This includes heart disease, cancer, metabolic syndrome, diabetes, Alzheimer’s and arthritis.
It has been speculated that one of the mechanisms behind olive oil’s benefits, is its ability to fight inflammation.
There is some evidence that oleic acid itself, the most prominent fatty acid in olive oil, can reduce inflammatory markers like C-Reactive Protein (6, 7).
But the main anti-inflammatory effects seem to be mediated by the antioxidants in olive oil, primarily oleocanthal, which has been shown to work like ibuprofen, a popular anti-inflammatory drug (8, 9).
Researchers estimate that the amount of oleocanthal in 50 ml (about 3.4 tablespoons) of extra virgin olive oil has an effect similar to 10% of the adult ibuprofen dosage for pain relief (10).
There is also a study showing that substances in olive oil can reduce expression of genes and proteins that mediate inflammation (11).
Keep in mind that chronic, low-level inflammation is usually fairly mild and it takes years or decades for it to do damage.
Eating plenty of extra virgin olive oil may help prevent this from happening, leading to a reduced risk of various inflammatory diseases… especially heart disease.
Bottom Line: Olive oil contains oleic acid and oleocanthal, nutrients that can fight inflammation. This may be the main reason for olive oil’s health benefits.
Extra Virgin Olive Oil Appears to be Protective Against Cardiovascular Disease
Cardiovascular diseases (heart disease and stroke) are the most common causes of death in the world (12).
Many observational studies show that death from these diseases is low in certain areas of the world, especially the countries around the Mediterranean Sea (13).
This observation originally spurred interest in the Mediterranean Diet, which is supposed to mimic the way the people in those countries eat (14).
Studies on the Mediterranean Diet show that it can help prevent heart disease. In onemajor study, it reduced heart attacks, strokes and death by 30% (15).
Extra virgin olive oil protects against heart disease via numerous mechanisms (16):
- Reduced Inflammation: As mentioned above, olive oil protects against inflammation, a key driver of heart disease (17, 18).
- LDL Cholesterol: Olive oil protects LDL particles from oxidative damage – a key step in the heart disease process (19).
- Improves Endothelial Function: Olive oil improves the function of the endothelium, which is the lining of the blood vessels (20, 21).
- Blood Clotting: Some studies suggest that olive oil can help prevent unwanted blood clotting, key features of heart attacks and strokes (22, 23).
- Lower Blood Pressure: One study in patients with elevated blood pressure found that olive oil reduced blood pressure significantly and cut the need for blood pressure meds by 48% (24).
Given the known biological effects of olive oil, it is not surprising to see that people who consume the most of it are significantly less likely to die from heart attacks and strokes (25, 26).
This really is just the tip of the iceberg. Dozens (if not hundreds) of studies in both animals and humans have shown that olive oil has major benefits for the heart.
I personally think the evidence is strong enough to recommend that people who have heart disease, or are at a high risk of getting it (family history, for example), should make sure to include plenty of extra virgin olive oil in their diets.
Bottom Line: Olive oil may be one of the healthiest foods you can eat for heart health. It lowers blood pressure, protects LDL particles from oxidation, reduces inflammation and may help prevent unwanted blood clotting.
Other Health Benefits of Extra Virgin Olive Oil
Although mostly studied for its effects on heart health, olive oil consumption has also been associated with a number of other health benefits.
Cancer is a common cause of death, characterized by uncontrolled growth of cells in the body.
Studies have shown that people in the Mediterranean countries have a fairly low risk of cancer and some have speculated that olive oil has something to do with it (27).
One potential contributor to cancer is oxidative damage due to free radicals, but extra virgin olive oil is high in antioxidants that reduce oxidative damage (28, 29).
The oleic acid in olive oil is also highly resistant to oxidation and has been shown to have beneficial effects on genes linked to cancer (30, 31).
Many studies in test tubes have shown that compounds in olive oil can help fight cancer at the molecular level (32, 33, 34).
Whether olive oil actually helps prevent cancer has yet to be studied in human controlled trials.
Olive Oil and Alzheimer’s Disease
Alzheimer’s disease is the world’s most common neurodegenerative disease and a leading cause of dementia.
One feature of Alzheimer’s is a buildup of protein tangles called beta amyloid plaques, in certain neurons in the brain.
A study in mice showed that a substance in olive oil can help to clear these plaques from the brain (35).
A human controlled trial showed that a mediterranean diet enriched with olive oil had favorable effects on brain function and reduced the risk of cognitive impairment (36).
Bottom Line: There is preliminary evidence that olive oil can help fight cancer and Alzheimer’s disease, although this needs to be confirmed in human controlled trials.
Can You Cook With it?
During cooking, fatty acids can oxidize. That is, they react with oxygen and become damaged.
It is mostly the double bonds in the fatty acid molecules that are responsible for this.
For this reason, saturated fats (no double bonds) are resistant to high heat, whilepolyunsaturated fats (many double bonds) are sensitive and become damaged.
It turns out that olive oil, which contains mostly monounsaturated fatty acids (only one double bond), is actually fairly resistant to high heat.
In one study, researchers heated extra virgin olive oil to 180 degrees Celsius (356 degrees Fahrenheit) for 36 hours. The oil was highly resistant to damage (37).
Another study used olive oil for deep frying, and it took 24-27 hours for it to reach damage levels that were deemed harmful (38).
Overall, olive oil seems to be very safe… even for cooking at a fairly high heat.
Take Home Message
Olive oil is super healthy.
For people with heart disease or at a high risk of getting it in the future, olive oil is most definitely a “superfood.”
However… it is extremely important to get the right stuff. That is, extra virgin olive oil that hasn’t been diluted with cheaper oils.
The benefits of this wonderful fat are among the few things that most people in nutrition actually agree on. Now that’s something you don’t see often.
