I am a little over 6 months post tx with Incivek, Peg and Riba
The hair loss was very bad for me this time.  While the last time I had all over thinning that I could take care of with trimming the ends, this time I ended up with bald spots over the ears and the entire back of my head had very short broken off hairs.

3 months post tx it was still falling out. it was devastating to me, I never realized how much importance I placed on my hair.  It was part of my identity.
I started using Nioxin level 4 but it dried my hair out.  So I switched to a more moisturizing Nioxin product.  It did help, I slowly started noticing less and less hair falling out.  I wanted to try something that would help my hair grow faster.  I started taking Hair, Skin, Nails vitamins with extra Biotin.

I found a site that sold a product which had been invented in Germany for people going through chemo.  On the site are some studies.   I have been using for 5 weeks or so, putting drops where the bare spots on, lightly rub in.  I noticed this week that where I had a receding hair line, there are now very tiny hairs growing back in, they are about 1/4 inch which means that all over my head hair is regrowing where there was no hair.
From what I read if the follicle is still active it will regrow hair.  This  product has been around for many years, is called Thymuskin Gel and I buy it from www.thymusking.com because they offer free shipping as well as free vitamins for hair called Advecia.  It is expensive however worth it to me because I need my hair back for my self esteem.  Once I get it started I should be able to decrease the amount of the product that I put on my scalp and it will continue to grow.  I compare it to a "kick start" for the follicles.
There is a good description on this site

UPDATE, it is now December 30th, my hair is coming in curly, I have about 4 inches of very thick curly hair.
I am so happy to have my hair back.  Saying that I would still trade my hair for a healthy liver any time.
It does come back, sometimes even better than before

The studies can be found on this site

                                              In the beginning was the Plan
                                           And then came the Assumptions
                                    And the Assumptions were without form
                            And The Plan was completely without substance
                          And the darkness was upon the face of the Workers
                                and they spoke among themselves, saying
                                    "It is a crock of ****, and it stinketh."
                         And the workers wen unto their Supervisors and sayeth
                      "It is a pail of dung and non may abide by the odor thereof."
                    And the Supervisors went unto their Managers ans sayeth unto the,
                            "It is a container of excrement and it is very strong,
                                          such that non may abide by it"
                          And the Managers went until their Directors and sayeth
                    "It is a vessel of fertilizer, and none may abide by it strength"
                And the Directors spoke among themselves, saying on to another,
                  It contains that which aids plant growth, and it is very strong"
          And the Directors went unto the Vice Presidents and sayeth unto them,
                             "It promotes growth and is very powerful"
               And the Vice Presidents went unto the President and sayeth unto him
                   "This new plan with actively promote the growth and efficiency of
                              this company, and these areas in particular"
                              And the President looked upon The Plan,
                     And saw it was good, and the The Plan became Policy,

                                    This is how **** Happens

Hi found this while looking for Ribavarin and hair loss,  due to the fact that my doc said it takes 6 months to get out of the body; I thought it might me helpful to a new person or even someone treating.  The VA has a site all about HCV

I also found this on riba.  While it was probably in my drug literature, at the time I started everything was very overwhelming and there was a lot to read.  Now that I am getting better I thought I should try to break it down for my own information

It has been a little over two months since I finished tx.  I am doing really well, with some minor problems that I am working hard to overcome.  The important part is that I am still UND.  Will be getting my blood work for 3 months soon and I believe it is gone.  I have not felt this well in a very long time.
During tx, I did not think I could do it, I worked very hard to get through the first 12 weeks only to have a medication interaction which was very scary, caused me to be anxious, no appetite, no sleep.  I was very afraid.  It lasted about 2 weeks.  Then I started to notice the sx from the peg and riba.  There were times I wanted to quit however the wonderful people here helped me to continue tx.
I thank God for the day I found this forum and all the people willing to reach down and give a hand up to me...who stayed with me during the entire tx, who never gave up on me even during my darkest days and who rejoiced with me when I was finished.  I would name all my friends however would be afraid I would forget someone so instead I say thank you to everyone.  I wish everyone SVR.  Bless you all
Chickadee!!
