Olive oil can be applied directly to hair to condition it. Heating the oil makes it a deep conditioning treatment. Apply it to the hair, and let it sit 20 to 40 minutes or overnight. Shampoo and condition the hair. Mix one egg, one-fourth of a peeled cucumber and 4 tablespoons of olive oil to make a mask. Leave it on for 10 minutes, and then shampoo the hair.
Hot olive oil treatments are also beneficial for scalp problems like dry scalp, psoriasis, dandruff and fungus. However, olive oil does not have to be heated before it is applied to the hair. Just apply the oil to the hair, and coat the entire strand. Massage it in until the hair is saturated. Cover the hair with a shower cap, and sit under a dryer for 15 to 20 minutes. Let it sit for another 5 to 10 minutes, and rinse it out with shampoo. For best results, use olive oil as a conditioner at least once a month.
Olive oil is beneficial to the hair because it penetrates the hair shaft with fatty acids. This leaves the hair feeling full and healthy. For added benefits, olive oil can be paired with other ingredients like honey, apple cider vinegar, avocado and mayonnaise.
