. Olive oil can seal moisture into the hair fiber, which helps with elasticity and results in less breakage. It can also penetrate the hair shaft and preserve moisture, making hair look shiny and soft. These properties can be particularly beneficial for those with dry and frizzy hair which can be more susceptible to breakages
. Olive oil has anti-inflammatory properties that can help calm down some of the inflammation on the scalp
. However, thin hair can be easily weighed down by olive oil, so those people should avoid overdoing it
. There is no concrete evidence that olive oil promotes hair growth, but it has protective and nutritional qualities that might make hair look and feel healthier. Olive oil is considered an active ingredient in many hair products, including some shampoos and conditioners. If you prefer to treat your hair with pure olive oil, you can do so by applying it to your head as a DIY mask
