you can't completely tell most of the time with a strand of hair. How your hair is when wet and also when it dries is usually an indicator. The strand does look like the elusive "z" shape according to Andre Walker associated with 4b hair characteristics. You may find that you have more than one type on your head which is common. I used to get caught up in hair typing but it ends in headaches. I think I have 3 types on my head alone but my concern has become more about giving my hair the respect it deserves after the many years of abuse.
