Olga... Mayo and olive oils sounds a) revolting and b) like a major pain in the tail-feathers, but I guess if it really works, it might be worthwhile... a lot would depend on the frequency.
How much of each?
Before or after shampooing?
How long do you need to leave it on?
And the big one... how often have you had to do it? If it's every time you shampoo, I somehow can't see myself going to that much trouble.
Thanks for the suggestion tho! It's probably not something I would ever have come up with on my own!
