I think the last poster kind of hinted at your answer but I thought I'd offer my two cents.
Refined castor oil has additives, in the case of JBCO that's ashes from the castor beans (the roasting process); the expelling process also tends to use more heat. Unrefined castor oil, particularly cold-pressed organic, is likelier to be food grade but check the labeling.
The pros of each depend on your intentions for use. I have used both kinds but in different ways.
Castor oil is known for hair thickening, revitalization, scalp stimulation, and hair regrowth properties. I've used it for all those reasons and more with success.
When I used food-grade, unrefined, cold-pressed castor oil, I used it everywhere and added it to everything and really loved it as a sealer, especially in the winter.
Currently, I'm using JBCO and I use that on my scalp only. The smell is too strong for me to desire using it elsewhere. I don't think it's an unappealing scent but I don't like my hair to smell burnt and no amount of essential oils sufficiently cover that scent for me. Also, unlike with my other castor oil, I don't like to put JBCO on my face or anywhere else the scent will linger. And obviously, it's not consumable.
I've only been using JBCO a few months so I've yet to see any discernible difference in my hair quality/hair growth.
I'd venture that regular food-grade castor oil has more nutrients/benefits because the oil hasn't been cooked (as heat degrades many vitamins/minerals etc). So it would make sense if that oil is better than JBCO. But out of curiosity, I tried JBCO anyway.
As far as making your own version of a castor oil based hair growth supplement, the benefits are: your ability to control the quality AND ingredients of your final product. I've always added rosemary, mint, lavender, and a host of other EOs and extracts known for their beneficial properties for hair, and heartily encourage that route before buying something packaged. And I have definitely seen the difference in my retention and hair quality while using castor oil versus not using castor oil. Just not in JBCO (refined) vs Cold-pressed Castor Oil (unrefined).
Whatever you end up using, I hope you won't forget the importance of drinking lots of water and a balanced diet. That probably helps twice as much as any product. And oftentimes, it's not what you use but HOW you use it.
HTH!
To the above ladies, thank you for replying. What I was referring to is on this website:
www.hairadrenalin.com and it is talked about on youtube.
On a separate issue, I was wondering about Castor Oil. Whether to use refined or unrefined. Does the type of Castor oil make a difference for hair growth/hair health?
