Mordechai Alvow of Pashah has spent years developing the formulas in his Yarok treatments to bring dry, flaky, and lifeless manes back to life. He has seven serums targeted for specific hair colors (blondes, brunettes, redheads) and problems (dry, sun-damaged, etc.). The ingredients are mostly essential oils (coconut, lavender, chamomile). Alvow looks at your hair and scalp, selects a serum, massages it into your head, then puts you under a steam machine. That’s followed by a shampoo and blow-dry. At the end, even the most fried and scrunchy tresses look new.
