I recently accidentally used a cone in a reformulated product, my hair went lank and stringy, it was a royal pain getting it back to bouncy curls. Never again, I get shine and bouncy curls from stuff like refined coconut oil deep treatments which is cheap as anything and proven to penetrate the hair reduce porosity and protein loss due to dying. Plus I like to see my hair naked sometimes and I don't want to be obliged to irritate or dry my sensitive skin with shampoo to do that: I don't like to be fooled that my hair is healthy, I made that mistake in the past.

IMO the 'labels' are useful shorthand, I don't see the word modified as being in any way negative. No one ingredient, product or technique will work for every single wavy or curly regardless of skin type, hair properties, length, local climate, etc.
