I found out castor oil causes me to brake out. I now stay away from anything that contains itI use Highwest Beard Company. I don't necessarily agree that all oils are the same. I tried a number of oils and they all made me break out. I was ready to give up on beard oil until I found Highwest. There must be something different about it.
For me, it's easier to list which ones I didn't like. First off, my olsest daughter is allergic to sandalwood, so if it has sandalwood in the ingredients it's a hard pass. I found Pinuad to feel heavy in my beard. I loved the scent, bit could not stand the thick heavy feeling. And Cremo didn't do it for me because of the scent.
That's from using probably 18 different companies you can find on the net plus another 12-15 small artisans. Nothing really stood out as OMG gotta have it this for the rest of my life products. So play around with various sample packs until you find something you like. That's my advice.
