I have been using tea rinses every week for the last month. I rinse green tea after my DT and leave it in until I am ready to exit the shower. I don't know if it is making my hair grow any faster, but my amount of shedding as decrease alot. Also my hair color seems to be a little richer. I am probably not seeing a large difference in growth because green tea has less caffine. I have an old can of coffee in my pantry so I'll switch to coffee and see what the difference is.
