I was told that after the oils stop over-producing they won't build up as long as you give yourself a scalp massage every day. The source came from someone that has been going all natural (no products at all) for over 8 years, however she has stick straight hair so I wasn't sure if it was the same for someone with curly. I plan on using a conditioner once ever 10-14 days either way, but I didn't want to upset the natural production of oil.

Since curlies don't brush their hair (at least while the hair is dry) and our hair shafts are bent, like NvmbrCurlss said, the oil can't travel down as easily.

THAT is why people with curly hair use conditioner, because it gives the hair moisture that we can't easily get otherwise. That's not to say that you can't wait for your natural oils on your scalp to return to a normal state after years of shampooing and wait for them to travel down your hair shaft, but you might suffer from dry, possibly brittle, hair in the meantime.

As others have said, the Curly Girl method is not a product-free method. CG instructs us to use a co-washing conditioner without silicones and/or a heavier leave-in/rinse out conditioner, which isn't completely washed out. Then, you style your hair with a silicone free gel.
