The timeline is different for every person as we all respond slightly different to medical treatments depending on a lot of factors. What we have seen is that most people stop losing their hair within the first 8 weeks and start to regrow new hair in the next 8 weeks. Some have seen faster results and some have taken longer. All of that is normal for these kinds of treatments. I know it is hard, but be patient and remember it has to work from the inside out so it may take some time to renew.
