DIY Beauty: hot oil treatment for curly, frizzy hair

All right, I don’t have curly or frizzy hair now but I did have them for maybe 10 years of my life. So here’s something that I used to do for my then curly hair once a week – using a hot oil hair treatment. The only difference is that I used a commercial blend back then but today, I’m going to share with you a hot oil hair treatment using normal vegetable oil. In this instance, it’s extra virgin oil oil from my kitchen cabinet.

Deep conditioning to repair damaged hair
Okay, first off, why do you even need to use a hot oil hair treatment? Well, if your hair is curly, chances are, it might be frizzy. So you probably need more help in the conditioning department. Besides using a hair conditioner, it would be good to give your hair some deeper conditioning to repair the damage and make your hair more smooth and manageable. Oil is a great ingredient for this purpose but instead of spending money purchasing products off the shelves, why not use what is readily available in your kitchen?

Various methods to heat up the oil
I find olive oil ideal for this deep hair conditioning treatment but you can always use sunflower oil or almond oil if those suit your fancy. There are a few ways to heat up the oil. One is over the frying pan, another is using the oven but here, I’m showing you the easiest, which is dipping a bottle of the oil into a bowl of piping hot water. I use this method because that was what I used to do with the commercial hot oil treatment products in the past.

Leaves hair smooth and manageable
After the oil is heated up, it should be very warm. Rub a little on your scalp – be careful if the oil is hot – and then through every part of your hair, massaging gently as you go. It is best to cover your head with a plastic shower cap for about 20 minutes so that the heat from your head will help the oil penetrate the hair shaft. Shampoo and rinse thoroughly after that and you should find your hair smoother and more manageable.

Recommended for dry hair too
Although I’ve indicated this treatment for hair that is curly and frizzy but you can also try it if your hair is dry and need some deep conditioning. Just make sure you have more than enough oil left for cooking!

    i have tried using the commercial hot oil without reheating it (sometimes i will just reheat with water from the shower), but it still worked the same for me somehow :p

    what about greasy hair? does that theory of oil dissolves oil works in this case too?

  3. sesame says:

    It should work without being hot…the heat however, will aid penetration into the hair shaft better.

  4. sesame says:

    Hmm…interesting question and I’m not sure of the answer. Oil can dissolve oil in terms of dirt and impurities but my guess is for the hair, it’ll work better to condition the scalp if the scalp is too dry and thus causing the hair to become greasier by the roots.

    thanks for the convenient (safer) tip for heating up the oil. I always microwave mine and sometimes, it can get really scary whenever the oil boils and pops inside the microwave. :S

  6. sesame says:

    Oh it freaks me out to heat up in the oven with the glass container. So I rather heat up using a pan or just hot water.

    Be careful not to fall into the trap that all oils work equally well.

    For example there is research showing that coconut and olive  oil can penetrate deep into hair and have a reparative effect (or at least help prevent future damage.) But other oils like sunflower oil mentioned in this post mostly sit on top of the hair and don’t penetrate much at all.

    In addition watch for so called “hot oil” treatments that don’t really contain any oil at all like VO5 and Suave. 

  8. sesame says:

    It’s good to know that coconut and olive oil do a better job for hair than sunflower oil. In certain cultures, coconut oil is used daily on their hair.

    need to wait for how long to shampoo hair?

  10. sesame says:

    About 20 mins…

    Thanks for the article. I am sitting with a shower cap on right now! I can already tell that this will work great. Thanks again!

    Glad it’s working for you!

    My tip for heating oil for head or body massage: use an aromatherapy burner! It works a charm. Plus you can add a few drops of aromatherapy oils for extra benefits (rosemary for dandruff, jojoba for conditioning etc). When the oil is hot, put out the little tea light and when it cools down you can relight it. Super easy.

    After hot oil treatment the wash should be with cool water or hot?

  15. Sesame says:

    You can use cool water.

    Wow….this is really amazing. I just love this. Thanks a lot for sharing.

    I started using oil treatments in my hair about a year ago when my stylist used one on my hair. I love the Somaluxe Argan Oil! It makes my hair super shiny and brings out my highlights and lowlights big time.

    The smell seems to last the whole day through too! Secondly, it contains my frizz in a big way which is nice because I heat style my hair and dye it and it was already frizzy to begin with before I started doing all that stuff.

    Is it advisable to do deep conditioning with hot oils daily for frizzy hair?
