Using oil alone may not be enough to hydrate and moisturize your hair, especially if your hair is naturally dry or damaged. While oil can help to seal in moisture and protect your hair from environmental factors, it may not be enough to provide the hydration that your hair needs.
Massage the Scalp: Begin by massaging oil into your scalp in circular motions to stimulate circulation. Focus on the Ends: Apply oil to the mid-lengths and ends where hair tends to be driest. Let It Sit: Leave the oil on for at least 30 minutes—or overnight for a deep treatment.
“Heat in the form of a hot towel or warm hair oil equals increased chances of absorption. You can warm up some oil in a bowl and apply it or use a hot towel on your hair after application,” she confirms.

Olive Oil: Best for Conditioning
Like coconut oil, olive oil is able to penetrate deep into hair's fibers. In fact, the abundance of monounsaturated fats found in olive oil may play a key role in its conditioning properties.

If you're wondering how to get rid of greasy hair for good, you're in the right place. Some common DIY ways to get rid of oily hair include baby powder, lemon juice, tea tree oil, baking soda, or apple cider vinegar, but adjusting your hair routine is a much better (and more effective) solution.
Overproduction of Sebum
Sebum is the natural oil produced by your scalp's sebaceous glands. It plays an important role in keeping your scalp and hair moisturized and protected. However, when your scalp produces too much sebum, it can make your hair look and feel greasy quickly, even when it's freshly washed.
Extreme weather changes can also disrupt your oil production, with cold weather being the commonly observed reason. Heat treatment through blow-dryers and straighteners can increase the temperature on your scalp and dry it out. Hormonal changes, including during moments of stress, can disrupt your oil production.
The wettability of the outer surface has a great influence on the oil-absorption performance. Hydrophobic and lipophilic treatment is applied to the outer surface of the material with low oil–water selectivity, the adhesion of oil substances on the surface becomes stronger, and it can better diffuse into the interior.
For day-to-day use, simply apply your oil to damp hair and let it air dry. If you're using a hair dryer or other heat-styling tool to achieve an effortless blow-out look, apply a few drops of hair oil through damp hair before applying heat. This will help lock in moisture and result in a smooth, polished finish.
While leaving oil on your hair may seem beneficial, prolonged exposure can have adverse effects. If hair growth oil is left on for extended periods, it can attract dirt, clog pores, and lead to dandruff and itching. Over-saturation may also weaken hair strands, making them prone to breakage.
