Vitamins and hairloss

I have very fine, thinning hair.  I'm wondering if anyone out there has tried vitamins to help hairloss or knows if you can take too many?  I  have done so much research on the internet.  Their are so many vitamins that claim to help hairloss.  I started taking Saw Palmetto, Kelp, Silica, MSM, B-Complex, Multiple, Hair vitamin and more.  I also started using Nioxin 4-step program.  I don't see hair in the shower drain anymore but still find it on my clothes and in the vacumm. 

The vitamins I've been taking haven't really done much to stop my hair loss...so I'm right there with you.

Hi Princess,  Besides taking so many vitamins I'm also having a saliva test done to test my hormones to see if I have an inbalance.  And I have also been reading a lot about hypothyroidism.  If your thyroid is off that can cause hair loss.  I spend hours a day researching hair loss.  I'm determined to find out the cause of mine.
