Users treating injuries with TB-500 noticed something strange: their hair was growing back in areas that had been thinning for years.
Based on 423+ community reports, some TB-500 users notice improved hair growth as an unexpected side effect while treating injuries. Reports include hairline filling, reduced shedding, and thicker hair growth. The effect is theorized to relate to TB-500's ability to promote cell migration and blood vessel formation, potentially reviving dormant hair follicles. However, this is not TB-500's primary use and results vary significantly.
“Wife noticed my hairline filling in after 6 weeks. Wasn't even trying to fix that, just my shoulder!”
“My drain is collecting way less hair since starting TB-500. The stuff on my head looks thicker too.”
“Crown area that was thinning for years is genuinely filling back in. I was using TB-500 for my Achilles.”
