I’m a vegan and I’ve been experiencing some hair loss which I think may have something to do with my diet. Does anyone know if I may be missing something that is linked with hair loss? What hair-loss product would you recommend?
Nioxin is like a shampoo that helps with hair loss they sell it at hair solons or maybe at stores where they sell beauty products only

The best shampoo for hair loss is a shampoo that does not contain any more chemicals that can worsen the condition. In my opinion, your best bet is to choose an organic shampoo that does not contain chemicals that can damage your hair and scalp further.
If you are losing hair, you should find out the reasons for it immediately because continuous hair thinning might resembles an underlying condition that you are not familiar of.
Supplement your diet with biotin capsules. That would help and you can take a lot of it without getting sick or overdosing. I’ve known people who have had success in reversing thinning hair with biotin supplementation.
Also, if you aren’t doing so already, start taking a green powder supplement daily. VerdiSyn is hard to beat for this. Perfect Food by Garden of Life is another good green powder. A tablespoon of a green powder a day in water or juice (preferably the former, without sugar) will ensure that you are getting all the B-Vitamins that you need in your diet, as well as some essential enzymes and minerals as well.
By the way, you are right to avoid meat as much as possible and to only eat organic meat once in a while (if at all). The antibiotics, hormones, and other additives injected in regular meat plays havoc on the body, and makes one fat from the hormones, among other things. Not to mention the fact that meat is also hard to break down and often goes undigested for long periods of time, especially among big meat eaters. Pork, pork sausage, and ham should especially be avoided completely, as these are very hard to digest – not even taking into account all the other problems, like the nitrates and nitrites added.
