Sorry for the late reply, I must have missed your post somehow.
Faire is sometimes used in a reflexive construction such as:
Je me fais faire les ongles. -- I am having my nails done.
Ils se sont faits agrandir la salle. -- They had the living room enlarged.
In these reflexive constructions (se faire + infinitive) the role of the subject is always a more passive one. One is having something done rather than doing it onself. Another example:
Je m'aide moi-même. -- I help myself.
Je me fais aider. -- I let myself being helped.
