Black tea has high levels of tannins. These polyphenol antioxidants don’t just help neutralize free radicals. They can also give you a quick color boost if you have darker strands. But TBH, the results prob won’t be super dramatic.

Black tea hair color results are temporary. It also doesn’t work as well in peeps with lighter hair shades like red, light brown, blonde, or white. If you really want to pump up the color volume, you’re better off using an actual hair dye.

Hair growth

Black tea rinses might help you get that Rapunzel lewk. The high caffeine content is thought to support a healthy scalp and hair as it might stimulate the hair follicles.

Hormones may also play a part. Some studies show that the caffeine in black tea can block dihydrotestosterone (DHT). This hormone can shorten the hair growth cycle, making new hairs shorter and thinner.
