Oil users: research on penetrative properties

daaiyah said:

For all you hair nerds (like me) who are interested in the how and why of oil penetration and protection of hair strands, I found the following links very interesting. Some of the research covers coconut oil, olive oil, mineral oil, and jojoba. I found it interesting that olive and coconut are both able to penetrate the hair shaft and prevent substantial protein loss. But because they absorb into the hair, heat and time keep them from forming a lasting film on the hair. If you have time read these, I see why so many people love coconut and olive.

Wow, thanks for the great info. I will now look at oils differently and will prolly use them according to what I wish to accomplish for my hair. After reading these article, I think there is a place for the penetrating oils like coconut and olive when you want to nourish and feed oils INSIDE the hair shaft. And a place for non-penetrating oils, like jojoba, sunflower, etc. when you want to seal and protect the hair by creating a lubricating layer on the outside of the hair shaft. IMO:

penetrating oil = nourish the inside of each strand
non-penetrating oil = seal and protect the outside of each strand

For example, I would use a non-penetrating oil like jojoba on my ends to seal and protect, rather than coconut, which will go straight inside the hair but leave the outside unprotected. At least that's how I'm thinking about it now . . .

I absolutely believe that jojoba is indeed and excellent hair oil! It is equivalent to sebum on scalp and lubricates and protects the hair on the outside hair shaft in same way that your natural sebum does. Natural sebum does not penetrate hair shaft, it protects hair.

Coconut and Olive penetrate, which is good, but IMHO, the non-penetrating oils serve an even greater function by PROTECTING and lubricating the outer layers of the hair. But that's just me . . .

Jojoba and castor have been my staple oils for years now and my hair is the longest and healthiest its ever been and ain't no way I'm throwing them out.

I very very rarely use olive and coconut cuz they both leave my hair kinda dry -- but I now understand why -- they penetrate! Hello!!!

I can now incorporate them back in my regimen understanding their function and how to use them for maximum benefit. . .

Knowledge is power! Don't throw out stuff that is working just because some new theory or research comes out. Think about it and think about how it's working for YOU before jumping. Cuz once you jump, another thoery will be out there contradicting. Jojoba has been my baby's daddy and no experiment out there can dispute my own personal experiment that it simply works for me, for years now . . .

I see now. Now I just have to remember to always use jojoba LAST.

But I do have a question, Why would coconut and olive oil leave your hair dry if they penetrate? Olive and coconut usually leave my hair feeling moisturized.

Another thing, if I am using my jojoba last, can I expect to get the full benefit of my (non-cheap) moisturizers the next day? or is it not until wash time?

Okay, here's my understanding. Olive, coconut and avocado may leave you dry after a period of time. That's because time and heat remove the film from the scales. So if you oil frequently it shouldn't matter.
And regarding the conditioner, I read something (not sure if it is one of the links) that moisture will still pass through oil coated strands just not as readily as uncoated ones.

This is seriously an important finding....But I have additional questions. How does Amla Oil and Castor Oil measure up? Are they able to penetrate the hair or do they just coat the hair?

I agree, sometimes a little information could be what you need to fine tune your routine.
