A true friend knows exactly how to fix what ails her closest confidantes. Stress at work calls for evening cocktails and chatter, while recovery from a lover’s quarrel requires long, analytical phone calls at all hours of the night. The truest gifts of friendship — patience, acceptance and honest advice — cannot be wrapped up with a satin ribbon and exchanged during the holidays. However, all of these heartfelt exchanges can lead to certain, more-material gifts that only a close friend would know to give. With the right insider information, one may determine the perfect remedy for a friend’s most pressing beauty conundrums.
