When it comes to conventional treatments for hair loss, there are a lot of possible side effects you should be aware of before using any of these options. Make sure to read warnings carefully and take them into serious consideration because a lot of the side effects are quite serious. For example, serious side effects of minoxidil products like Rogaine can include unwanted facial/body hair, dizziness, fast/ irregular heartbeat , fainting, chest pain, swelling of hands/feet, unusual weight gain, tiredness and difficulty breathing.

Multiple vitamins, including biotin, have been promoted for hair growth, but solid scientific studies for many of these claims are lacking. While taking biotin and other supplements marketed for hair, skin, and nails probably won't worsen anything, it may also not necessarily help the situation. Therefore, advertised hair-regrowth supplements should be approached with mild caution. There is only anecdotal evidence that oral or topical application garlic , onion juice, saw palmetto, coconut oil, evening primrose oil , apple cider vinegar, creatine, and pumpkin seed oil are of benefit for hair loss.
In my opinion the best shampoos out there are DS Laboratories Revita Hair Growth Stimulating Shampoo, RegenePure and Wick & Strom. DS Labs Revita shampoo ticks almost all the boxes. However, it’s very expensive. If $25 is a bit excessive (which it probably is for most people), you might be better off going for a natural or even organic shampoo that is isn’t specifically labelled as a hair loss shampoo. The problem with a lot of hair loss shampoos is they contain ingredients that may help promote hair growth, but to save money they’ve used cheap base ingredients like sodium lauryl sulphate.
