1. GK HAIR Professional Hair Taming Serum — Best Straightening Oil

Starting off the list, we’ve got GK Hair Taming Serum. When I’m making a list of hair products, I’m almost always going to include a keratin product in the top three because keratin does so much for your hair. This serum penetrates the hair fiber to fortify it from within, giving your hair the nourishment it needs while protecting it from heat styling. On days that you’re too busy to flat iron but you still want beautiful flyaway-free hair, it can also smooth naturally styled hair.

Key Features

  • Lightweight keratin and argan formula
  • Creates a layer of protection around the hair
  • Can be used with or without heat

Apply a dime-sized amount of GK HAIR Serum to clean dry or damp hair before styling. For those looking for a silicone-free product, be aware that this product does contain natural, water-soluble silicones. These are different from plastic-based silicones that are known to create buildup on hair. This serum does not create buildup, but the manufacturer cannot claim that this product is “silicone-free.”


  • Keratin and argan oil leave hair super nourished
  • Smooths away flyaways and frizz even before styling
  • Makes hair super shiny


  • Not silicone-free

For a great hair straightening oil that nourishes your hair and adds extra shine, GK HAIR Professional Serum is a great choice. Use it every day to keep your hair nourished and feeling loved, even on non-styling days.


2. Viva Naturals Organic Extra Virgin Coconut Oil


Okay, so this isn’t necessarily a “hair straightening oil” per se, but I have included Viva Naturals Organic Extra Virgin Coconut Oil because it is a highly effective heat protector. Made from fresh organic coconuts, this cold-pressed coconut oil can be used as a hair mask, a skin moisturizer, and a heat styling product. It is completely scent-free, and it is even safe to cook with. If you don’t have a jar of cold-pressed coconut oil in your house already, get this right now because you will find a use for it.

Key Features

  • Cold-pressed extra virgin organic coconut oil
  • No additives
  • Food-grade

To use Viva Naturals Organic Extra Virgin Coconut Oil as a styling product, melt a small chunk of coconut oil in your hands and apply a thin layer to your hair before styling. Avoid using brands of coconut oil that are liquid at room temperature. They have additives in them to maintain the liquid form. Organic coconut oil should remain solid at room temperature. You can also use Viva Naturals Organic Extra Virgin Coconut Oil as a leave-in conditioner after styling.


  • Use it for EVERYTHING! It’s a hair mask, a moisturizer, a styling product, and you can eat it!
  • Absolutely no additives, so it’s great for people with scent sensitivities
  • Extremely nourishing to hair


  • Fine hair may get weighed down by coconut oil

If you have allergies or are just trying to go a little more green with your hair products, try Viva Naturals Organic Extra Virgin Coconut Oil. It’s a great all-in-one additive- and scent-free oil that is the perfect hair straightening oil.


3. Majestic Pure Moroccan Argan Oil

If you like a no-frills, fragrance-free, no-additives hair straightening oil, but your hair just doesn’t do well with coconut oil, try Majestic Pure Moroccan Argan Oil. This golden yellow oil is smooth in texture and has a natural nutty scent. Because it has no added preservatives or scents, it is unlikely to trigger an allergic reaction. But it is always advisable to test the oil on a patch of skin before applying a larger amount. Majestic Pure Moroccan Argan Oil moisturizes hair, skin, and nails.

Key Features

  • Cold-pressed southwestern Moroccan argan oil
  • No additives
  • Safe for hair, skin, and nails

To use Majestic Pure Moroccan Argan Oil as a hair straightening oil, apply a small amount of Majestic Pure Moroccan Argan Oil to your palms after washing your hair. Work the oil through damp hair and style as usual. Use Majestic Pure Moroccan Argan Oil as a leave-in conditioner, or add a few drops to your hair throughout the day to smooth away frizzies and boost shine.


  • Extremely versatile product with multiple applications
  • Unlikely to trigger allergies or scent sensitivities
  • Paraben-free, alcohol-free, and not tested on animals


  • Can weigh hair down if you use too much

If you’re in the market for a one-and-done hair straightening oil, but you’re just not cuckoo for coconut oil, reach for Majestic Pure Moroccan Argan Oil. It’s a high-quality, additive-free cold-pressed argan oil that can be used both to style the hair and nourish the skin and nails. The only thing you can’t do is eat it!

Factors to Consider for Picking the Best Straightening Oils

When selecting a hair straightening oil, there are a lot of factors to consider. The process of selecting the best hair straightening oil for your hair can involve a lot of trial and error, so I’ve assembled an easy buyer’s guide to help guide you on your quest for smooth, straight hair.

Hair Texture

We all know that no two hair textures are exactly alike, so it’s important to know your specific curl pattern and look for straightening oils that work well with your hair. Also, take into account damage that may have occurred to hair during the styling process. If your hair gets damaged, you might need to change up your products because damage affects the texture.

Style Needs

For most women, styling their hair is a multi-day process. It’s a pain in the neck to have to style your hair every single day. If you want hair that stays sleek and styled and holds its style for multiple days, you need to choose the correct products for both creating and maintaining your hairstyle. Think of styling holistically; from washing to styling to maintaining the style, you need to use products that nourish your hair without weighing it down.

Scalp Status

So, we talk a LOT about hair, but girl, how’s your scalp? Allergies to certain ingredients and scents in products can cause allergic reactions. Some allergic reactions are dramatic and scary, but most people with ingredient sensitivities only have mild symptoms like an itchy and flaking scalp. Remember, only a licensed dermatologist can run an allergy panel of your beauty products to officially determine if you have an allergy or ingredient sensitivity, so if you believe you have an allergy talk to your doctor.


I can not tell you how many times I have been last-minute packing for a trip only to discover that I have no room in my suitcase for my styling products. It can be a real dilemma when the taxi is about to take you to the airport, and you only have enough suitcase space for either your hair products or your cute shoes! Learn from my mistakes. Get a travel-size set of your favorite hair products. You take a lot of photos on vacation, so you definitely want your beautifully coiffed hair to come with you.

Hair Health

As mentioned before, damage will affect your hair’s texture and how it responds to styling and products. For this reason, it is essential to invest in quality styling tools that will not create hot spots that burn your hair. You want hair straightening oils that maintain your hairstyle for multiple days without exposing it to more heat, thus reducing the chance of damaging the hair. If you suspect your hair is damaged, make sure to apply a hair mask to repair the damage.


Can I straighten hair with oil in it?

This might be a little controversial among hair enthusiasts, but yes, you can straighten hair with oil in it. Coconut, grapeseed, and argan oil all function as fantastic heat protectors. Just be sure not to use too much because if your hair is over-oiled, the straightener will have a harder time straightening your hair. When in doubt, read the directions printed on the bottle.

How do I use a hair straightening oil?

If your hair straightening oil is also a heat protector, apply a thin layer of oil to the hair before you flat iron it. Some straightening oils are meant to be used in the hair after styling to maintain the sleekness, so check the label to verify the usage instructions.

Which kind of hair oil is best for straightening?

That really depends on your hair. Some people’s hair loves coconut oil, whereas others find the coconut oil weighs their strands down. Like I said before, coconut, grapeseed, and argan oil all work as fantastic heat protectors, so experiment around and see what works best for you. When it comes to hair straightening oil, it’s hard to recommend a one-size-fits-all product. Shop around and find out what’s the best product for you.

Final Thoughts on Hair Straightening Oils

While all these hair straightening oils are wonderful, my top pick would have to be GK Serum. Personally. I love that it keeps my silk press looking sleek and lovely until my next wash. If you’re like me and you’re too busy to flat iron your hair every day, this is a must-have product.

However, as mentioned before, different hair reacts to hair straightening oil in different ways, so don’t be afraid to shop around to find the best straightening oil for your hair. Say goodbye to poofy hair and hello to beautiful, sleek strands!
