Tea water, usually does not make the eyebrows thicker. If you experience eyebrow hair loss and thinning, visit a hospital dermatologist if necessary.
Whether eyebrows are thicker or not is considered to be related to an individual’s own constitution and genetic factors. If the grandparents or parents have thick eyebrows, their children may have thicker eyebrows due to genetic factors.
Tea water is made from tea leaves and is rich in tea polyphenols and vitamins. Applying tea water to eyebrows or drinking tea water regularly does not have a significant effect on eyebrow growth, so tea water usually does not make eyebrows thicker.
In the summer heat, tea water usually can not be stored for a long time, otherwise it is easy to rot and spoil, breeding bacteria. If you ingest rotten and spoiled tea, it may cause acute gastroenteritis, resulting in abdominal pain and diarrhea. If there are small breaks at the eyebrows, applying overnight tea water to the eyebrows, bacteria invade the broken skin and may induce infection.
To summarize, tea water has more nutrients in it, but drinking tea water or applying it to your eyebrows usually does not promote eyebrow growth. If you have thinning or shedding eyebrows, it is recommended that you visit a hospital dermatologist to find out the cause, and also to give treatment for the cause.
