lady with red hair or lady with the red hair??

Hi, which of the following sentences should be considered correct??

1a) The lady with red hair is my neighbour.

1b) The lady with the red hair is my enighbour.

2a) The lady in red dress is my teacher.

2b) The lady in the red dress is my teacher.

3a) The old man in the red car is my boss.

3b) The old man in red car is my boss.

It seems 1a, 1b, 2a, 2b and 3a are correct but not 3b. Am I correct??

Thanks

2a) The lady in red dress is my teacher => it needs 'the' before the 'red dress' because the speaker is talking about a lady who is already known. Besides, in this case 'red dress' is a countable noun. 3b) the same here. It needs 'the' before the 'red car'. Both sentences, they sound not right without 'the'.

 I agree!

There are times articles are not needed, i.e. Women in high heels and short skirts usually get a lot of attention.  In general statement like this, no article is needed.
