QFQ: Does coconut oil ruin elastic bands?
A: Yes, I noticed it too, coconut oil does seem to degrade rubber more than any other hair product that I have used. Scientifically, I could not find a study on this although the fact that many things can degrade rubber is known (friction, water, heat, alcohol etc). I do agree with your observation, yes coconut oil does seem to affect elastic and loosen it . I guess I like coconut oil more so I am happy to replace the elastic items and keep using the oil.
