Protection Of Hair From Damage Induced By Ultraviolet Irradiation Using Tea (Camellia Sinensis) Extracts

In this study, the multifunctional Hair BB Cream containing botanical extracts and other ingredients improved hair combability, increased shine and strength, and provided UV protection, highlighting its potential as an effective hair care product.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

This study found that ultraviolet radiation causes significant damage to human hair follicles, including increased cell apoptosis and oxidative DNA damage, but this damage may be mitigated by topical caffeine.

This study found that caffeic acid reduced UVB-induced damage and oxidative stress in human dermal papilla cells, suggesting its protective efficacy against such cellular damage.

In this laboratory study, researchers reported that Camellia sinensis seed flavonoids significantly reduced oxidative stress and inflammation in UV-irradiated skin cells by modulating key signaling pathways, highlighting its potential as a skincare ingredient for anti-inflammatory and anti-photoaging benefits.
