We do not use a reflexive pronoun after verbs which describe things people usually do for themselves, such as wash, shave, dress:
He washed [himself] in cold water.
He always shaved [himself] before going out in the evening.
Michael dressed [himself] and got ready for the party.
We only use reflexives with these verbs for emphasis:
He dressed himself in spite of his injuries.
She’s old enough to wash herself.http://learnenglish.britishcouncil.org/ ... e-pronouns
When NOT to use reflexive pronouns
1. There are a number of verbs in English with which we rarely or never use reflexive pronouns (as they are in other languages).
They include: adapt, complain, concentrate, get up, hide, lie down, meet, move, relax, remember, shave, shower, sit down.
2. After a preposition of place or location we use a personal pronoun and not a reflexive pronoun.
• He put the backpack next to him.http://www.grammar.cl/Notes/Reflexive_Pronouns.htmhttp://www.englishlanguageguide.com/gra ... ronoun.asphttp://www.bbc.co.uk/worldservice/learn ... v109.shtml
