Women can spend up to two and a half years of their life washing and styling their hair. That’s a lot of time spent doing our hair, but how much do we really know about it? Here are 20 strange hair growth facts that you may not have known about your hair.
20 Strange Hair Growth Facts

3. Individual hairs go through 3 phases: anagen (growing), catagen (transitional), and telogen (shedding).
