Oksana Grigorieva claims Mel Gibson scratched and bruised her during their January 6 fight, but Mel has an alternate explanation ... Oksana did it to herself.
TMZ has obtained a declaration from Mady Shany, Oksana's facialist. Shany says on January 12, Oksana came in for a facial, and she noted, "I noticed that there were scratches and bruises around her eyes and on her forehead."
Shany says Oksana told her Mel "punched her and threw her on the bed while she had the baby in her arms."
But TMZ has also obtained a declaration from Mel, in which he claims, "...Oksana is emotionally unstable and suffers from Trichotillomania, an impulse control disorder characterized by the repeated urge to pull, and pulling, out ones own hair, eyelashes, eyebrows and other body hair."
In the declaration, Mel says, "During our relationship Oksana often had scratches and bald spots on the side of her head as a result of this disorder (scratches she is now, apparently, attempting to blame on me!)."
Oksana's lawyer, Dan Horowitz, tells TMZ, "I've spent over 100 hours with Oksana and I have never seen her pick her hair or scratch her skin. She just acts like a totally normal person."
