No .. not over the 6+ years that I took it. I have now been taken off of it due to the inadequate level of absolute lymphocytes, however, hair is good. 8~}

I don’t think my hair has thinned from Tecfidera, just getting grayer with age

Yes - my hair has thinned quite a bit. The scalp is more visible, and the coarseness of each hair blade is thinner. Compare it to unhealthy lawn.

I’ve been on Techfedera for almost 4 years and my hair is just as thick as ever.🤦🏻‍♀️

I've been on Tecfidera since 2014 and I haven't noticed hair loss. I just turned 64 in September so I've been fortunate in many ways.
