View Full Version : Why Not Use Soybean Oil?

I have a question, mostly out of curiosity. I noticed a lot of people use Jojoba, Coconut oil, Avocado Oil, and Castor on their hair, leaving out the most convenient oil...soy. Why not? Has anyone else tried it? I know soy is in some of Giovanni's products (not sure if it's soy protein or soy oil), and I've used it personally and LOVED it. It's fairly light on my hair and puts a nice shine that lasts a long time similar to dimethicone (at least on my hair). It's a good sealant and mixed with coconut oil has pretty much saved my hair for hot oiling, and I use it in my emulsions too. So...is anyone else using soy or has had good experiences with it?

Coconut and avocado oil are widely used because the hair can actually absorb them. I don't know much about soy oil, but if you like the results, keep on keeping on.

Given its availability, I'm surprised that it isn't used more often but I suppose using vegetable oil doesn't have quite the same ring as some of the others you mentioned.

I try not to buy too many single use products other than an essential oil or high quality carrier here and there so many of my hair/body oils double as cooking oil: extra virgin olive oil, virgin coconut oil, sunflower, untoasted sesame, argan (food-grade), and grapeseed (although I'm phasing this out due to high pesticide levels found in most commercial grape harvests & seed oil production).

Virgin coconut oil is great for cooking as well as a natural anti-fungal supplement. As far as hair application use, it's one of the best hair oils since it is actually able to penetrate the hair shaft and helps prevent protein loss. Plus, the natural scent of unrefined coconut oil is pretty hard to beat!

I don't cook with castor or jojoba (and I'm not even sure you can) but their natural properties make them desirable for skin and hair use, as well as alternative home remedies: castor oil for laxative purposes and suffocating the all too common hair follicle (demodex) mites that inhibit hair growth; jojoba oil's similarity to our skin's natural sebum makes it a good choice for a lightweight oil cleanser and moisturizer, especially for the scalp (although some people prefer to use it on the length).

Avocado oil (unrefined) has a much higher vitamin E content than soy oil and it's considered less comedogenic.

Also, there are so many conflicting studies as to whether or not soy oil contains phytoestrogens, which can be absorbed through the skin. That's an important factor to consider for people undergoing hormone replacement therapy or with synthetic hormone sensitivity.

I haven't tried it, but now I might have to. I think I have some in my pantry.

Of the oils I've tried so far, my favorite is sesame (recommended to me by Mira-chan). My hair sucks it up a bit more than it does coconut and olive oil, and it adds a nice amount of slip and shine. Plus it's another grocery store oil, which I consider a selling point.

When I first started using oils, back 5 years ago, I started with shortening (, which was hydrogenated Cottonseed and soybean oil. It worked ok for me. I've also used a soybean and olive oil blend I got at Dollar Tree.

I think there was a study concluding that soybean oil, when applied topically, slows hair's growth and makes it grow in finer. That is probably why it is infrequently used on head hair, but the study was referring to body hair, so I think that as long as you are only applying it to the ends and not the roots, it will have no negative effects. =)

good question.. I know it's one of the first oils in the Africa's Best oil people like in the other thread. What about canola oil? I see that in some products too! I wonder if they are cheap filler oils like how mineral oil is used?

This article is mostly about soybean oil on skin - i ran into it while looking up how to treat eczema - but there might be some useful info. for hair:

And this article at LiveStrong.com claims that soybean oil stimulates hair growth.

However, this article at FutureDerm, says that soybean oil used on the skin reduces the number of hair follicles!

WOW! Talk about two opposites :confused:
I do remember hearing thay soy and vitamin E will thin out the hair follicles prevent them from growing. And then I found this article too, that claims that soy prevents baldness :

This just lets you know how unreliable the internet can be when finding the truth about ingredients. Everything is so extreme. It's either "This ingredient will give you cancer and make your hair fall out" or ""This ingredient is a hidden gem and will make your hair grow in a matter of seconds!". Here's an article I found on Soybean oil preventing baldness.

http://www.scq.ubc.ca/soybean-and-baldness-preventation-apparently-there-is-a-link/

I don't believe any of it honestly. It's a carrier oil not an essential oil or herb. It adds shine to my hair in mixes and an herbal butter I use for growth actually has soy at the beginning of the list (my hair has been in the best condition now than it has in a while since I've been putting it on my ends and scalp actually).

I just thought there was some reason regarding past experiences as to why people didn't use soy oil. Like heavy feel or something. It's so easy to come by I don't see the harm in giving it a try. It does work well (just as well) as other carrier oils..it's really underrated. :)

To boot suppliers who sell different types of butters actually mix it (hydrogenated soy) with other oils and receive rave reviews. Soy is the active ingredient because it's more of it. I know a lot of 4 types were also using it as a sealant.

I have never seen soybean oil, perhaps its not popular in my country. I don't generally look at the vegetable oil section of the grocery store but still I've never noticed it. I've just looked up my local store online and no they don't sell it.

I do know that soybean is frequently genetically modified, also the oil is often hydrolised and I imagine it might be difficult to obtain an organic variety.
I prefer all my oils cold pressed - can soybean oil even be obtained via cold pressing?

Soybean oil can't be obtained by cold-pressing, or even by expeller pressing with heat. The only way it can be extracted is chemically, by using a solvent. Hexane, a pretty nasty petrochemical, is what is generally used.

Wow, dropinthebucket! That is cool information. Especially these parts:

shown in independent research studies to exhibit both anti-inflammatory and antioxidant properties, and to stimulate the production of collagen and hyaluronic acid...

increase the firmness, elasticity, and suppleness of skin. These findings have been affirmed in this 2005 study in the journal of Photochemistry and Photobiology, which further reported that use of soy extract twice daily for two weeks reduced the number of hair follicles (dermal papillae) on the skin.

2000 study in the journal Dermatology that human trials demonstrate lightening of hyperpigmentation after use of soybean extract for two weeks.

This sounds great for the Oil Cleansing Method! (I heard some women had increased facial hair from the usually used castor oil.) But on the other hand, I wouldn't want my eyelashes or eyebrows to be thinned - I guess careful application would be key.

Here's the conflicting part:

some soy-containing products have estrogenic effects, which can make this form of melasma (darkening of the skin) worse.

As to using soybean oil on the hair - I would keep it away from the scalp (just in case), but on the length it should be fine.

I think Milui Elenath and Velouria definately hit the nail on the head with this one.
Most soybeans are genetically modified. It is very hard to find any soy product that states "non GMO" except at specialty stores. And most who know about how oils are obtained (I found out on LHC) want to avoid chemical solvents.

I recommend coconut oil to a friend at school once, and she ended up buying cooking (soybean) oil because it was cheaper...it ended up leaving a very wavy residue on her hair. It didn't absorb into her cortex at all. She had to go to the salon for a clarifying treatment. :( I never really recommend natural hair products to my friends anymore because they never really listen.

I myself am afraid of soybean oil. I don't like the idea of GMO soybeans and I don't even trust that soy is good for you at all.

When I was in peri menopause I once had my period for 2 weeks straight. Finally in desperation I went to the pharmacy and looked at the OTC pills for women going through the change of life and ALL of them had soy as the main ingredient. So I just went and bought a carton of soymilk and drank 1 glass.

Less than an hour later my period stopped - AND NEVER RETURNED!!! Is that some powerful stuff or what???

It literally made me believe the phyto estrogen things that I've read and I stay away from it now.

Also soybeans (not sure about oil) are supposed to slow the thyroid gland hormone production.

And about the oil - I've read both that it is good for hair and that if you use it on your shaved skin it will deter hair from growing back. Same with lard for some reason! But people use Crisco (and lard or I have) a lot on their skin and hair so I don't know... but I don't want to :)

If anyone has good luck with it please post!

This!! I don't touch anything soy except for fermented soy sauces that are guaranteed non-GMO. (Hard to avoid because it's in everything.) No soybean oil for me either.

Indeed, there is a lot of info that goes like that. Thats why it is important to check the references. More often than not, some writer has misinterpreted or overrated some findings in a report somewhere or taken them out of context.

I can't find soy oil in my country, but I have seen it mixed with other oils in massage products. I bought it in Germany once, and it pulled out my henndigo completely (not intended :o I'm not the only one who this happened to. I think it's not sold so often here because of all the people allergic to peanuts.

I have used canola oil (mostly it's not labelled separately, but sold as rape seed oil) for homemade shower products, but I havent put it in my hair yet. I don't care very much for the smell.

lol, it seems whatever that has to do with soy we get conflicting results and a lot of emotion. My Africa's best carrot Tea tree oil therapy has it as a main ingredient, I use it as a body lotion, heavenly stuff for my skin. It's a little too thick for my hair, I get build up easily.

That's not true. The soy bean oil is often pressed out.

Wikipedia is funny sometimes. Just because it isn't mentioned there, doesn't mean it doesn't exist. It says in WIkipedia also that it is the most sold cooking oil in the world ?? I have lived in many countries and I couldn't find it in any of them :o Another info that wasn't complete. The pressed oil as well as the press leftover-cake is often used in animal food (pellets and such for lifestock for example). Also there is no mentioning about the issues with GMO.

Thinking about the promotion of hair growth on the head but reduction in other places could it be that hair that grows on the face, legs etc is caused by testosterone and the soya's phytoestrogens inhibit that. Then hair that grows on the head is promoted by estrogen so the phytoestrogens in the soya oil promote that?

It does sound quite nice to use a bit like a serum maybe. It may not do the job of coconut oil but sometimes sitting on the surface protecting the hair is what you want.

Oh, interesting theory and sounds logical!

I always have soya milk in tea, I'm 48 and I (TMI warning) have never yet missed a period. I prefer the taste to cow's milk but maybe it's unhealthy?

I have some of the Africa's best oil but I didn't like it much on my hair. If I find someone who likes it I will give it to them. Olive oil is amazing as a pre-wash treatment though.

Because it's usually labelled as "vegetable oil." If you look at the ingredients it says soybean oil.

I've never seen this type of oil in shops, I don't think it's widely available in my country. I have been wondering if rapeseed oil (the main ingredient in our vegetable oils) would work well on hair though.

Places to find soybean oil:

Oils that just say 'Vegetable oil' often are either 100% soybean or soybean mixed with other oils, esp. cheap oils
Crisco and generic shortenings

Any oil that doesn't tell you what it is is probably soybean oil. :(

Calling something "vegetable oil" is not allowed in my country. It would imply hiding true ingredients or possibility of adding lesser quality ingredients.

Also Qrisco is not available here, had to look it up. Similar products are available in Germany though, usually of animal origin, not plant source.

This showes one of the issues with people talking about various products mentioned here on LHC. They aren't always available where you live or the similar ones available are made of something entirely different. Baby oils for example, are not often made of mineral oil here in Sweden. But usually when people discuss baby oil they mean mineral oil.
