Sealing Experiment: Why You Should Seal After Moisturizing

Left: jojoba | Right: grapeseed
I've wondered for a while if, on a basic level (what I mean is not factoring in the different benefits each oil has on hair) one oil seals better than another. Think of the strands of your hair as the jars. When you moisturize your hair, you're restoring moisture to it. Sealing with an oil traps the moisture into your hair.

So on October 26, 2012 I started a little experiment. I filled 5 mason jars (and I'll admit, I have a bit of a mason jar obsession, I use them to organize and store tons of things around my home) with 12 ounces of water each. I added oil to four of the jars: jojoba, grapeseed, almond, and coconut oil, leaving the fifth jar with only water to serve as the control.

You may have seen on the JGA Facebook page that the first picture I posted of the jars was taken with the jars on the windowsill... they didn't live there long. Blame my peeping-tom of a kitty. She likes to lay/sit/walk across my window sills to watch the outside world and I didn't trust her not to bump the jars. I ended up moving them to my dining table.

Results (November 15, 2012): for sealing purposes, there is no difference between the oils. All four oils effectively prevented moisture loss, while the water in the control jar without the oil evaporated a little past the half way mark (just under 6 oz).

Regardless of what oil you chose, sealing will lock moisture into your strands, so if you aren't sealing after applying a moisturizer, give it try.

I didn't choose jojoba, grapeseed, almond, or coconut oil for this experiment because they're the "best" oils to seal with, they're just the oils I had on hand (although I'll admit, it's no secret, my fave is grapeseed!). If you have fine hair, you may want to choose a lighter oil, like coconut or jojoba. If you're seeking more bang for your buck and want to reap the benefits of adding ceramides into your regimen (read about the benefits of ceramides here), you may want to choose to seal with grapeseed oil, hempseed oil, or sunflower oil. 

Do not feel as though you have to limit yourself to oils right out the bottle either. Sealing with an oil-based moisturizer is a great way to seal in your water-based moisturizer too. My current fave oil-based moisturizer to seal with is Coconut Mango Hair Moisturizer by HairitageHydration but there are plenty others. Sometimes, I even seal with Organix Coconut Milk Anti-Breakage Serum.


If you were hesitant about sealing, I hope this post and little experiment helped!

  5. Very interesting experiment Jeni. If this doesn't show how important sealing is I don't know what does.

  7. Most excellent, the visual of over 1/2 the water that wasn't sealed evaporating is outstanding. Good job Jeni!

  8. Great experiment! I stopped using oils awhile ago for no particular reason. I've been using the Organix Coconut Milk Anti-Breakage Serum to seal with. I'm really liking it.

  9. I love this experiment, I remember someone (don't ask me who now...lol) did a similar experiment that I re-posted but she only used one oil. It was nice seeing little to no difference in sealing power between the oils - its just a matter of preference. *grabs Bee Mine & grapeseed oil now* lol!!!

  11. I was looking forward to the results of this experiment that's good to know that they're all comparable sealants--Great experiment. Although after reading this post, I now want some grapeseed oil for my stash, too. Thanks, Jeni. :)

  16. This was very informative. It changed my perspective on moisturizing and sealing. I was just wondering does sealing with an oil matter at all but I now see that it does make a difference. Thanks for the experiment

  17. I love this experiment. Thanks so much for producing an excellent reminder of how useful sealing after moisturizing can be :)

  18. Wow, this is really interesting! I love that you conducted a visual experiment to support this instead of just simply telling us that sealing is good for our hair. I think anyone who doesn't know, understand, or value the purpose of sealing will definitely get it after coming across this post.

  19. This is a wonderful experiment and it hammers home the importance of oiling and sealing. Thanks!

  20. I wonder how much water would be missing if it were Summer (when the air is more humid). Hmm....Superb lesson though, Miss! Thank you! I'll pass it on to my readers.

  21. Ok, convinced!! I always moisturize but never seal as I don't like the feel of oil in my hair (I use coconut or avocado) but I will give it a try. thanks for sharing this!

  22. This kind of reminds me of this little spray bottle I have with coconut oil, olive oil, sweet almond oil, water, Infusiun 23, and some conditioner in it. And it gets cool in the house, or the temperature drops, the oils seal in the liquid, so when I turn it upside down, nothing happens!

  29. Wow this is crazy. I learn better visually and this just did it for me. Can't believe that much water evaporated when it didn't have that layer of oil above it. Yep! Sealing is a YES YES for me!!
