cod liver oil

[jojo]

I have been taking cod liver oil for arthritis for approx a month now and getting really good results, no swelling and only slight pain in my hands but my hair seems to be getting greasy. Ive not had greasy hair like this since I was going through puberty and my 2 pregnancies, well it does go greasy after 4 days of not washing but nothing like this:confused:

Anybody else notice this? its no biggie, I just need to wash every other day but how can a little supplement make my hair so greasy?
