There is no hard and fast rule about what does and what doesn't make a "TS".  If a girl is on hormones, doesn't need to shave her face, has breasts (natural or implants), lives full time as a girl, female voice, and has feminine actions and manners, then I would tend to call that person a TS.

If they don't live full time as a girl, they still need to shave, are not on hormones, no breasts, sound like a guy, acts like a guy, only dress as a girl for work, etc... then I would tend to classify that person as a TV.

Although, let me stress, there are exceptions to every rule.  Not everyone fits into nice little labels.  A TS or TV could be made up of a mixture of those two examples.

If the ONLY thing you are going by is long hair.... then there sure are a lot of TS's walking around that don't even know they are TS!!!!
