Let me take a risk here, and say yes you can have too many staples.
In reorganizing all of my stuff, I have too much crap. I have to get everything that we talk about here on the boards.
I think back to what I may have posted in the past about this or that product that worked great when I finally am realizing that I yield the same results with fewer and far less product.
As an example, I'm natural and instead of applying shampoo, conditioner a leave in and then something for shine, and then something for hold, I find that after washing and conditioning my hair shea butter alone provides all that I need as leave-in, shine and holding properties.
Don't get me wrong, I love experiementing with all the products, but it really is a waste of money that I can't really afford to be spending.
Another example, is a $14. (or whatever) product to whiten our teeth, when for $.50 a bottle of hydrogen peroxide will do the same thing.
(Maybe, a poor example but you get the point)
Or, trying all this different products that contain shea butter from different companies, or this person or that made it. Get some raw shea butter and call it a day.
For those that can afford it financially and have the physical space for it, I'm jealous
