topicals products vs natural ingredients

[researchingeverything]

Do we really have to spend money on topicals products such as Rejuveplex Topical ?...according to what im reading think nature provides us with enough ingredients to change bacteria homeostasis on the scalp and stop hair loss....onion juice, rosemary, topical kefir or nettle are examples of ingredients that should change bacteria homeostasis on the scalp...


Or do these topicals that sell on the web and stores have other benefits that natural ingredients cannot provide?
