My hair has been coming out by the bucket load for about 4 weeks now - been on SS for 15 weeks. I can see little straggly hairs growing through (unfortunately grey!) so it is coming back - I go into my kitchen as see loads on the floor and I get a bit worried but think as soon as I go up a plan it will come back. Someone told me it comes back nicer - not sure though. I have been taking Silica-OK for a month and a B-complex so hopefully this will help
