According to Experts, We Should All Be Using This Divisive Hair Product

Much like face oils, hair oils also have the power to divide beauty buffs far and wide. While some love the nourishing, intensely moisturising properties of hair oils, others detest their weighty, greasy nature and prefer to stick to the best conditioner or hair mask. However, unlike face oils, when it comes to expert opinion, the general consensus is that, actually, adding a hair oil into your routine can only make things better; you just need to know how to use them.

As someone with incredibly thick, wavy hair, I have used hair oils for as long as I can remember. I use a lot of heat and bleach on my ends, so this product is my secret weapon when it comes to taming flyaways and adding shine. Although I tend to opt for a thicker consistency, after years of testing these products out, I've come across so many lightweight oils that would be perfect for finer and thin hair types.

In fact, I've tried so many different hair oils that I thought it was about time to round up my favourite ones on the market that deliver shine without leaving a hint of greasiness. But before we get into my product selection, I wanted to reach out to those most in the know to find out a little more about this divisive hair product.

What Does a Hair Oil Do?

"Hair oils help to seal the hair cuticle, laying it flat and adding smoothness and shine. Many oils contain fatty acids, which replace the lipids in damaged hair,” says Andrew Barton, Headmaster's creative and communications director.

And it turns out that you don’t just have to have dry, dehydrated strands to reap the benefits of oils. "It’s a myth that hair oils will weigh hair down, making it feel heavy and look oily. In fact, oils can be more lightweight than a balsam-based conditioning agent, and they always add shine. The key to using them is in the application,” advises Barton.

Of course, there are also lots of scalp oils on the market. These are slightly different from your typical hair oil as they are applied to the roots of the hair instead of the ends. "You should skip heavy oils for the scalp," says award-winning hairstylist Dalibor Vrtina. "If applied properly, [these] hair oils can add nutrients, stimulate the scalp and even help control dandruff and itchiness."

Can All Hair Types Use a Hair Oil?

As mentioned above, everyone can benefit from adding a hair oil into their routine. In the most obvious case, hair oils are truly wonderful at adding moisture to dry strands. Those with a dry, coarse hair texture are likely to see the most transformative results out of using a hair oil. Depending on your specific texture and your chosen product, oils to treat dry strands can be used in different ways. "The best oils for dry hair tend to be more concentrated forms like argan, coconut and avocado oil. For seriously dry hair, I advise using oils after your shampoo to provide ultimate hydration,” says Antony Rawlings, creative director at Lockonego for Redken. Depending on the formula, you can also use as a pre-wash treatment, a post-wash leave-in treatment or apply it to dry ends on non-wash days to increase shine and manageability.

That being said, a hair oil can be used on fine hair types, too. "The secret to using hair oils on fine hair is to control the amount you use,” says Barton. "Less is more, so apply only one drop, to begin with, and build up if you need more. Massage two to three drops into the palms, tip your head upside down and apply the oil through the length. To minimise breakage, I like to comb it through with a Manta hairbrush.”

If you have curly or coily hair, Vrtina recommends looking for an oil with a thicker consistency. "I would definitely recommend thicker oils," he says. "My advice would be to use it on wet hair so you can lock in that moisture."

How to Use a Hair Oil

Using a hair oil correctly is totally dependant on what kind of product you go for. Some can be used on damp hair, while others can only be used on dry ends, so I always recommend reading the instructions. However, Vrtina does have some top tips. If you're using oil as a finishing step, he recommends putting a few drops between your palms and applying evenly along the lengths and ends. "There is no need to do your roots, but if you want to calm down any flyaways, you can [apply it to the roots], just don’t go too heavy with it."
