According to this if your hair didnt sink its good thing......
This test procedure evaluates the hydrophobicity of hair after treatment with the compositions disclosed below:
Dry hair fibers were cut to about 0.635 cm (about 1/4 inch) in length and weighed to about 0.02 gram. The hair fibers were spread out on a piece of glazed paper within a one square centimeter area. The fiber mass was transferred from the paper and placed gently on the surface of water ( about 40 ml of water in a 50 ml beaker). The length of time the fiber mass remained floating before sinking into the water was recorded.
If the hair was hydrophobic, it would float on the surface for over an hour. Hydrophilic hair fibers, on the other hand, would sink into the water within 30 seconds. Under this test, normal untreated virgin hair was hydrophobic whereas hair that had been chemically treated with an oxidative hair tint, bleach and/or permanent wave products was hydrophilic.
It seems hydrophobic is a good thing since normal virgin hair does shy away from water... i think it just means your cuticle is well intact,, its not an issue... http://64.233.169.104/search?q=cache:HBFl4p1_tn0J:www.freepatentsonline.com/4614200.html+hair+porosity+test+sink&hl=en&ct=clnk&cd=6&gl=us&client=firefox-a
