From coconut hair oil to onion hair oil, the possibilities are endless. 

The benefits of hair oil:

Difference Between Hair Oil and Hair Serum - Hair Serum vs Hair Oil 

Hair oils or hair serums, which one is the superior hair product that’ll take care of your every hair need? Well, the answer isn’t that simple. It all depends on what exactly it is you’re looking for from your hair product. While one is a pre-wash ritual, the other works better once you wash your hair. When one takes a deeper approach, the other protects it superficially –– however, both work together for the greater good of your hair.

Here’s the difference between hair oil and hair serum.



Hair Oil

Hair Serum


Once a week

Post every wash and before styling


Thick and oily



Treatment approach

Styling approach


Deeply nourishes and conditions the scalp as well as the hair, maintaining your hair’s overall health

A topical agent that coats each strand and prevents frizz, split ends, and flyaways on the spot

The lubrication penetrates deep into the cuticles, preventing breakage from the very root of your hair

Most serums contain silicone that coats each strand and protects it from heat styling. This also prevents breakage during styling

Great for damaged hair that needs deep conditioning

Great for styling and treating split ends and dry hair to make it more manageable


What Is Better - Hair Oil Or Hair Serum

If you’re looking for a long-term solution to major haircare problems, it’s better to nip it in the bud. In this sense, opting for hair oils would make more sense. It’s literally the one-stop product that’ll solve your issues. The only downside? The texture tends to be very thick, which makes it a bit of a pain to wash off. Oiling your hair means putting it up in a bun or braid for the entire time you apply the oil.

As for hair serums, they are an immediate solution for issues like split ends and flyaways. They are the perfect protectors for when you want to style your hair, as well. That doesn’t mean they do not provide long-term benefits. Regular application helps fix damaged hair as well. Since they are made for styling you don’t need to worry about looking like a greaseball.

You can either use one or the other or use both together for better results. Deep condition your hair at least once a week for that extra nourishment, and apply a serum after a hair wash or when styling your hair. That’ll give your hair the protection it needs.






Is serum or oil better for hair?

There is no comparison between a hair serum or hair oil. Both haircare products have different functions and qualities to offer for your hair. Hair serum is basically a hairstyling product that adds shine and protects hair from heat damage. Whereas a hair oil adds nourishment to hair, prevents dandruff, enhances hair growth, and improves overall hair quality too. 

Can you use hair oil and serum together?

We wouldn’t recommend using hair oil and hair serum together. It’s good to use both products separately at different intervals. You should use hair oil at least twice or thrice a week(before hair wash), whereas hair serum should be used whenever you style your hair(after hair wash). 

What's the Best Way to Use Hair Oils and Hair Serums?

How to use hair serum: First, warm up the product for 5 seconds, apply the product from the ends up to the middle of your strands, and spread hair serum evenly with your hands, and it’s done.


How to use hair oil: First apply the hair oil to your scalp and massage with fingertips in circular motions. Then apply the left oil on your palms to your hair. Then cover your hair with a soft towel and leave it overnight. Then shampoo your hair the next day.

In the battle between hair serum vs hair oil there isn’t a clear winner –– this is because both are equally effective. We’re happy now you know what is hair serum and hair oil, and how are they different from each other. Hair that requires a little extra TLC needs extra nourishment too. This kind of hair is usually dry, dull, and brittle, and is usually coupled with scalp conditions like dandruff. Using hair oil takes care of those issues, ensuring that your hair grows strong from within. On the other hand, hair serums take a more topical approach. They are great for when you want to style your hair, settle down split ends and flyaways –– here the main goal is to give you manageable hair, along with nourishing it simultaneously.
