I take the supplements listed in my signature, plus nettle and kelp, lecithin, vitamin b6 and acv softgel called KLB6. I mix my aloe vera with my goji juice. I love to add parsley to lots of things I eat. Parsley is a whole food and is also very good for hair. I have a big canister of powdered herbs nettle, burdock, comfrey, oatstraw, rosemary, kelp, barley grass. irish moss that I mix in my conditioners and homemade scalp concoction. I also mix in aloe vera.
I have taken ACV straight out the bottle and pure, organic, unrefined coconut oil, but both are hard to choke down (unless I dilute the ACV with alot of water) so I have never been consistent with it. Coconut oil is so good for you internally, but that stuff is hard to choke down. It feels like you have a mouth full of grease, which is exactly what you have...
Next up on my supplements to try is the black vinegar capsules and coconut oil softgels. A couple years ago, I read that the coconut oil in the softgels are not really effective because in order to get the full benefit of the two tablespoons a day that is recommended, you would have to take like a half bottle of the softgels a day, but maybe just taking in some of the good stuff even if it isn't two tablespoons will be beneficial. Also, the black vinegar is supposed to be 43 times more powerful than ACV. I am still researching and trying to figure out how/where they got 43 times more powerful from (smile) as the number seems arbitrary to me although I do not doubt that black vinegar is more powerful.
P.S.: I forgot to say that I take my supplements for health. I added the nettle a few months ago and PP sent me double my order by mistake, so I have been taking the nettle for a few months now, but I tried that specifically for hair. Everything else I have been taking for years before I started researching good hair care "best practices."
