The User Profile API may help you.

use the event.sender.id received from the messenger bot server (/webhook), and follow the request below

curl -X GET "https://graph.facebook.com/v2.6/<USER_ID>?fields=first_name,last_name,profile_pic,locale,timezone,gender&access_token=<PAGE_ACCESS_TOKEN>"

then you could get the returned json below

{
     "first_name": "Peter",
     "last_name": "Chang",
     "profile_pic": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-xpf1/v/t1.0-1/p200x200/13055603_10105219398495383_8237637584159975445_n.jpg?oh=1d241d4b6d4dac50eaf9bb73288ea192&oe=57AF5C03&__gda__=1470213755_ab17c8c8e3a0a447fed3f272fa2179ce",
     "locale": "en_US",
     "timezone": -7,
     "gender": "male"
}
