I am no beauty expert, but two things I know is that the Rachel haircut is arguably the most significant chop in recent history and that Drunk Elephant is one of the most buzzy names in the industry right now. Combine these two things and you’re onto a winner. The skincare brand (which is the fastest-growing in Sephora’s history) just branched out beyond vitamin C serum and overnight oils into hair and body products, and enlisted the help of Jennifer Aniston’s long-time hairstylist Chris McMillan. Yes he is the man behind the ‘Rachel.’
