Longer Hair:
Remember Rapunzel? Once her braid was long enough, she tossed it down to the prince and girl was outta there. Today, she'd be in trouble. Between dye jobs, stress, and styling, growing hair can be a beyotch. To the rescue: these accelerators and illusionist tricks.
In-Shower Secret
Shampoo matters! "Hair follicles are only 1.25 mm below the surface of the scalp, so cleansing ingredients really can reach them," says Elizabeth Cunnane Phillips, a hair scientist at the Philip Kingsley Trichological Clinic, in New York. Look for formulas enriched with vitamins E and B5, zinc, iron, and copper — they increase keratin production, the building block of hair.
Game-Changing Treatment
Instead of having your stylist trim ratty ends, find one who offers the Brazilian Blowout Professional Split-End Repair (about $25, brazilianblowout.com). Amino acids and seaweed extracts bond tattered fibers (like a liquid Band-Aid) for up to a month.
