Green tea is made from the leaves of the Camellia sinensis plant and is rich in catechins, especially epigallocatechin gallate (EGCG), a widely researched antioxidant compound.
Oxygenated stress is considered one of the mechanisms associated with hair follicles aging and premature graying. Free radicals can damage melanocyte cells - cells that create melanin pigment for hair. Therefore, a diet rich in antioxidants is believed to support protecting hair follicles to a certain extent.
A study published in PubMed shows that EGCG in green tea has the ability to affect hair follicles - a group of cells that play an important role in the hair growth cycle.
Some other studies also show that catechin in green tea has the ability to support blood circulation under the scalp and protect cells from oxidative stress. This is why green tea often appears in many shampoo and hair care serum products today.
From a practical usage perspective, green tea can be used in two common ways: drinking and scalp care.
For drinking, experts recommend using pure green tea in moderation, about 1-2 cups per day. Green tea can be combined with lemon or mint to enhance the flavor without adding too much sugar.
According to Harvard T.H. Chan School of Public Health, green tea contains polyphenols and flavonoids that are related to supporting cardiovascular health and metabolism when used in moderation. In addition, green tea is almost calorie-free if not added sugar, suitable for a healthy diet.
In addition to drinking, many people also use green tea water to massage or lightly spray the scalp after washing. From a scientific perspective, scalp massage can help increase blood circulation in hair follicles, while antioxidant compounds in green tea can help reduce mild inflammation in oily or easily irritated scalp.
According to nutrition experts, the most scientific way to support healthy hair is still to maintain a balanced diet, rich in green vegetables, good quality protein, omega-3 and natural antioxidants. Getting enough sleep, limiting smoking and controlling stress are also very important for hair follicle health.
