Hair Facts

Hair is made of a protein called keratin. The average person has about 100,000 to 150,000 hair strands on their head. Hair grows about half an inch per month, and each strand has a lifespan of about 2-7 years. It’s normal to lose 50-100 hairs a day. Hair color is determined by melanin, with more melanin resulting in darker hair. Hair doesn’t grow after you die; the skin shrinks, making hair appear longer. Cutting your hair doesn’t make it grow faster, but it can help reduce split ends. Hair is one of the fastest-growing tissues in the body.
