If your hair is thick and not easily weighed down and dry you might like the nourish and shine. My hair isn't super thick but I just use a tiny bit for a finisher and shine so it works fine.
I bet the lighter version I'd have to watch how much I use less but this one works fine. I smoothed it on a dry patch the other day and it fixed it right up.
JennyFurrens might be able to help you on that light version since that's the one she got
2c/3a?
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
