Below are some of the best non-prescription products that help regrow hair or help combat the inflammation and dandruff that often accompanies hair loss. All of them have numerous largely positive reviews on Amazon.

Ever since this excellent product was made available in the much easier to apply foam version, I have always maintained an ample supply. Rogaine is FDA approved to treat hair loss. Besides helping my hair, it also acts as a weak gel.
Note: You can also check this site for lower-cost Minoxidil.
A Japanese product. There is some solid evidence and backing behind it and the company (Shiseido) that makes it is one of the world’s leading cosmetics companies and is also working on a hair loss cure. Adenovital is a big hit in Asian markets.
An extremely popular product. There is significant evidence that caffeine and saw palmetto are somewhat beneficial to hair growth. Saw palmetto blocks the formation of DHT and is often described as a natural (but much weaker) alternative to Finasteride. For more on that, see my post on natural cures for hair loss. Also make sure to read caffeine as an alternative treatment for hair loss. The Ultrax shampoo product also contains 0.2% Ketoconazole, which reduces dandruff and also has some anti-androgenic properties (see bottom of my Nizoral post).
A great product if you really need more hair for a special occasion or have small balding areas that need covering up. For more, see my write-up on Toppik as well as on other hair loss concealers.
My favorite shampoo to tackle dry and itchy scalp problems. See my post on Nizoral. However, do not overdo it. I try to use this product twice a week at most. Make sure to keep it in your hair for at least several minutes before rinsing it off. This product contains 1% Ketoconazole.
