Olive oil has the ability to condition dry hair, strengthen hair follicles, repair damage, and keep hair manageable. This results in stronger hair and lesser hair fall. While there's no strong evidence to support hair growth, olive oil is said to boost overall hair health, which means it'll help grow hair faster.

Apply the oil on dry areas of hair or scalp, which will vary from person-to-person. Cover the hair with a shower cap and let the oil sit on the hair for about 15 minutes. Rinse the oil out of the hair with warm water. Shampoo the hair, repeating this step if the olive oil leaves the hair greasy.
