I am going to tell you something VERY few people know. I head it from a very WISE SYCHATRIST AND HE WAS A NEUROLOGIST. SO READ IT ALL Now If you hold the skin around and under your brows its thicker. That's Because under the Eyebrows is such a Complex System of Nerves Under the two eyebrows is where the all the Balance happens of Body size and The hair on the Head to Memory. Like Mountains Balance the earths crust from shaking For ex: A mountain which is 5,000 ft tall is 10,000ft deep in ground its like a Peg. SO are the hairs on the eyebrows they are so much deeper than other hair they connect to the nervous system under the eyebrows. Now if you pluck them you will face these problem in long term. 1: If you notice older people who's eyebrows are thicker on the edges their scalp hair are thicker on the sides. People who's eyebrows are thicker near the middle their hair are heavier in the middle of their scalp.Eyebrows have a big BALANCE with hair on the head.
2: Since the eyebrow hair are like pegs connected deep to the nervous lines if you pluck or thread your eyebrows in the Middle and make the gap between your eyebrows longer than its natural gap you will not also lose hair near the forehead but also will also start having after 7 years of time or so. "So try not to pluck in the middle a lot. My mother had this same problem after she realized.
3: So Women or men who pluck their eyebrows their program for hair falling starts. Try not to pluck your eye brows to far in the middle. and dont thread your eyebrows too think try to keep the normal and pluck as least as possible.
