Creating this DIY Hot Oil Treatment for Hair

I’ve been growing my hair out for about 2 1/2 years now. I started with a short bob with lots of stacked laters and now have hair that’s past my shoulders with some long layers. I love it!

The last time I had long hair was pre-children. I didn’t really know how to do my hair all that great back then. I didn’t own a flat iron or even a good curling iron. I’ve definitely learned a lot about styling longer hair in the last couple of years.

One of the downsides to the growing out process is that the ends can get pretty dry since it isn’t being trimmed as much or as frequently, and my hair sheds a lot more (or maybe I just notice it more since my hair is so much longer).

Rosemary Hair Oil: Using Hot Oil Hair Treatments

About 6 months ago, I started doing weekly Hot Oil Hair Treatments for my scalp and hair.

I have noticed a huge difference in my hair and scalp health since I started using this DIY Rosemary Hot Oil Hair Treatment.

Even though I’m really bad about noticing my own hair growth because I see my hair everyday, friends and my hairdresser are always commenting on how long my hair is now and that it grows so fast.

So, in addition to having scalp that is moisturized and dandruff-free, and soft, shiny hair, my hair is growing super fast. Great news to me, because I would still like it to be a couple of inches longer than where I’m at now.

What are the Benefits of Hot Oil Hair Treatments?

Each ingredient in this DIY Rosemary Hot Oil Hair Treatment is beneficial to the hair and scalp.

When using this hair treatment, you may see any of the following benefits:

  • stronger hair
  • reduced dandruff or itching scalp
  • moisturized hair
  • softer, smoother, more manageable hair
  • less frizz
  • increased shine

By warming the oil prior to adding it to your hair, dry, damaged ends are extremely moisturized. The hot oil helps seal the ends, giving dry hair a smoother, softer feel.

Massaging this oil treatment into the hair and scalp also benefits by increasing circulation to the scalp. This helps by promoting overall scalp and hair health as well as boosting the growth process.

Ingredients to Make a Hot Oil Hair Treatment

This DIY Rosemary Hot Oil Hair Treatment is a great way to soothe dry scalp and dandruff, promote healthy hair growth, and add shine and moisture to your hair. You’ll need the following ingredients:

Carrier Oils in this Rosemary Hair Oil

  • Coconut Oil – Unlike commercial moisturizers that are full of water (and other chemicals), coconut oil’s moisturizing powers are deep and long lasting. It deeply moisturizes because it can penetrate the hair shaft.
  • Jojoba Oil – adds shine to the hair and promotes softer, more manageable hair. It also soothes the scalp as an effective treatment for dandruff.
  • Castor Oil – known for its ability to promote hair growth and thicken hair. It also moisturizes hair and seals ends, helping to prevent breakage.

Your carrier oil needs to be a pure oil and not a massage oil that contains additives, synthetic ingredients, or additives.

Essential Oils in this Hot Oil Hair Treatment

  • Rosemary Essential Oil – Rosemary can stimulate hair growth, increase blood circulation to the scalp and slow shedding, helps with dandruff, and gives hair body. Rosemary oil is also said to have antibacterial properties and anti-inflammatory properties. Can you see why rosemary oil has become a popular hair regrowth treatment ingredient? Make sure you are using a pure essential oil, not one with additives, fragrances, or synthetic ingredients.

Rosemary and lavender smell very nice together. So you may like to add a few drops of lavender essential oil along with your drops of rosemary oil, though it is not required for the recipe.

Making a DIY Hot Oil Hair Treatment is so easy!

All you need to do is measure the ingredients listed in the recipe, combine them in a saucepan and heat until the oils are warmed and combined. The coconut oil should completely melt.

Then, add the essential oil and stir. After that, transfer it to your preferred storage container until use! (I love these amber glass bottles with droppers)

The above is simply a quick summary of this recipe. Check out the full recipe in the free printable recipe card at the bottom of this post for all the detailed instructions.

Using a Hot Oil Hair Treatment

Now that you know the benefits of rosemary oil for hair and how to make this hot oil treatment for hair, here’s how you use it:

What to Do Before Applying the Rosemary Hair Oil

For best results, wash your hair with a clarifying shampoo first to remove excess build up if you use a lot of hair products.

How to Use this Rosemary Hair Oil Treatment

  • Add a few tablespoons to a plastic squeeze bottle or bottle with a dropper.
  • Heat water until hot (or use hot water from the faucet) and place it in a bowl.
  • Place the bottle in the hot water, with the lid on, and let sit until the oil has warmed.
  • Use the dropper or squeeze bottle tip to apply a small amount of oil at the roots in sections. Repeat throughout.
  • Add oil to the ends. Massage the warm oil into the scalp and all the way to the ends of the hair. Comb through if desired.
  • Place hair in a shower cap and let sit for at least 30 minutes before washing.

Bonus – run a bath and soak in these Lavender Eucalyptus Green Tea Bath Salts while you let your hot oil treatment sit on your hair.

Hot Oil Hair Treatment Safety

Make sure you conduct a patch test first, especially if you have sensitive skin. If you notice any skin irritation do not apply to your scalp. If you develop any scalp irritation or unpleasant side effects after using this rosemary hair oil, discontinue use and consult your doctor.

Test the oil before applying to make sure the oil isn’t too hot so you don’t burn scalp. Don’t use if allergic to any of the ingredients. This Rosemary Hair Oil is for external use only.

Using Hot Oil Hair Treatments Overnight

Once a week, the night before I know I am going to wash my hair, I will massage a few tablespoons of this DIY Rosemary Hot Oil Hair Treatment into my scalp and hair.

Then, I braid my hair and sleep with it overnight. Make sure to cover your pillow with an old towel, otherwise the oil can stain the pillowcase.

For extra protection, you can sleep with a shower cap on your head, too.

What is the Best Way to Rinse a Hot Oil Treatment from Hair?

If you’ve ever done overnight scalp treatments on your hair, you might be wondering how do I wash the oil treatment out of my hair??? Because if you do shampoo your hair a bunch of times to get the oil out, then you just undid all the benefits of the oil by stripping your hair!

I don’t remember where, but I read that this was a great tip to help wash the oil out of hair without having to shampoo it 5 times. I don’t know why, but it is the easiest way and totally works!

  • In the morning, I beat and egg with a couple tablespoons of water and massage that into my wet hair in the shower.
  • Just use cold water to wet the hair and rinse out the egg, unless you want to end up with cooked egg in your hair.
  • After rinsing the egg, then shampoo and condition as normal.

My hair is so much softer and the dry ends way less brittle.
