This question is worded rather oddly. The average person loses 100 hairs per day, 100 new hairs
are also regenerated. The average human hair grows at a rate of one half inch per month. The way the
question is worded, I would have to answer that 100% of our hair grows daily.
On an average hair grows upto half an inch per month. It also depnds on the hair care routine and the intake of diet. Vitamin E and proteins are the major source of strength for hair growth. The intake of these also determines of the length of the hair growth.
Hair grows approximately 1/2 per month or. 4 mm per day. Hair is made from kerotin, which is a protein so your diet attributes to the rate at which your hair grows, and your nails as well. Regular trims will keep your hair from becoming damaged and breaking off.
