We dont actually know. The number of people using Taurine as a hair loss preventative appears to be very small, and we have not conducted any research on the subject.

This article is therefore designed as a signpost to resources available elsewhere, that may enable those considering the use of Taurine to make a more informed decision.

How is Taurine supposed to help?

As one source puts it:

L-taurine is an amino acid that when used orally at doses greater than 500 mg. acts as anti-fibrotic agent (inhibits the inflammatoin mediated hardening or ridgification of the hair follicle matrix), thus addressing the primary mechanism of the gradual follicle miniturization seen in MPB.

L’Oreal recently obtained a patent for oral hair growth compound that simply combined L-Taurine with Grapeseed Extract, Mega Green Tea Extract, OptiZinc, and Beta Sitosterol. In data submited by L’Oreal in their patent application, topical L-Taurine was found to be ineffective for hair growth.
