A 2015 study found that oils can help revive hair with a much-needed moisture boost. Another study from 2021 found that coconut oil strengthens hair fibers. Especially for hair that's been affected by intense styling and heat damage, hair oiling can fill in some gaps to keep it moisturized and, in turn, silky smooth.
Turns out, hair growth oil could be your ticket. Though more research is needed, there are a few studies that show specific oils aid hair growth—specifically bergamot oil, coconut oil, olive oil, and peppermint essential oil, says Dr. Gretchen Frieling, a triple board-certified dermatopathologist in Boston.
A number of essential oils including lavender, rosemary, thyme, and cedarwood are effective in boosting hair growth. Some carrier oils like jojoba oil, coconut oil, olive oil, almond oil, castor oil, etc. can also be used to improve hair growth.
Oiling hair has “a multi-dimensional effect”, says Dr Rohini Wadhwani of Skin Essentials, “It helps by increasing the tensile strength of the hair, reducing the frizziness and preventing breakage.” The oil, by coating the hair, forms a protective layer for the hair shaft.
Oiling your hair 1-2 times a week is enough. Doing it everyday can attract dirt and also strip away essential oils from your hair. Combing, rubbing and vigorously massaging your hair with oil can also cause breakage.
Applying the hair oil while the hair is damp will nourish and protect the fiber it from unwanted frizz as it dries into a subtle, shiny version of its natural texture. Once the hair is dry, you can use another pump of hair oil into your palms and warm it between your fingertips.
“You can oil when your hair is damp or dry, but your hair and scalp have to be clean, or the oil won't have a chance to be absorbed,” says Dr Gupta. For heavier oils like coconut oil, applying it on dry hair is best, as the larger molecules may not penetrate the shaft of wet hair as well it can dry hair.
Avoid oiling your hair if you have an oily scalp
“There are high chances of getting an infection if you apply oil frequently on an oily scalp. You can do it once in a blue moon. Also, if you have acne on your forehead then avoid applying oil to the crown region,” she suggests.
The moment your hair is left to soak in oil for more than 12 hours, your scalp collects dirt and mixes with your scalp's natural oil. Leaving oil on your hair overnight can make it greasy and sticky, and it will also attract dust from your pillow and bed. As a result, it can lead to hair loss and other hair problems.

Here's the hard truth: Little can be done to permanently change the diameter of individual hair strands. Thickening products can do wonders to temporarily plump hair strands, but when it comes down to it, fine hair is genetic and can't be changed.
When your glands are producing too much oil, this can cause your hair and scalp to be overly greasy. Although this seems harmless, excess oil can clog pores on your scalp which can prevent your hair follicles from growing normally! And as a result, you may experience rapid hair loss.
The problem is when you do not wash off the excess oil properly. The remaining oil tends to attract dust and other pollutants, clog the pores on the scalp and block the hair follicles which eventually leads to hair fall and a plenty of it. An oily scalp can also result in dandruff which in turn can lead to hair loss.
In general, it is not recommended to leave oil on for more than 6-8 hours, as that might make things tricky. The oil can attract a lot of dirt, dust, grime and get them to stick to your hair! So, it will take a lot more effort to wash your hair with all this added stuff to wash off.
Oil your hair no more than 1 to 2 times a week. Leave it on for approximately an hour or two but you don't need to leave it on longer than that. When you leave oil on too long you run the risk of zits because oil will run down onto your skin and you also don't add any real benefit by leaving it on longer.
Avoid leaving oil in overnight
The longer, the better — that may be true for some hair treatments but not for hair oiling as the oil can block your hair follicles. Unless an ayurvedic doctor or expert has asked you to leave a medicated oil overnight, wash out the oil within 3-4 hours.
As a regular practice, it is natural to reach out for your comb right after oiling your hair to remove tangles. But this is a common mistake and you should avoid it. After a good oil massage, you scalp becomes relaxed and fragile, combing your hair immediately after can cause hair breakage and hair loss.
Macadamia Oil
Macadamia oil is extracted from macadamia nuts and is enriched with fatty acids. These fatty acids make it one of the best hair oils for dry and frizzy hair. If you frequently style your hair with heat tools, using hair masks with macadamia oil can deeply nourish your hair.
