Olive oil can be used in a hot oil treatment, combined with tea tree oil, made into a mask, combine with cinnamon and honey or taken orally to stimulate hair growth. Olive oil provides important nutritional benefits for humans and also helps to improve the quality of human hair. Olive oil is equally effective for supporting hair nutrition when applied topically and when ingested.
Regardless of whether using olive oil as a dietary supplement or topical treatment to stimulate hair growth, people should use certain types of olive oils, which are high-quality virgin or extra virgin olive oils, to make hair the strongest and healthiest that it can be. These oils are typically ingested or used in smaller quantities, which makes them more cost-effective. They are also minimally processed, and produced without chemicals, which makes them less likely to produce adverse reactions. Olive oil can be used as a hot oil treatment by combining equal parts of olive oil and castor oil in a bowl, then heating the combination to a lukewarm temperature. The warm mixture is applied to the scalp and massaged for approximately 10 minutes, followed by wrapping the hair in a towel to prevent moisture from escaping. When finished, hair should be thoroughly washed.
