My hair has led a rather audacious existence in her 30-plus years. She’s dabbled in the murky waters of at-home kits, entertained a long and loving affair with foil highlighting, and even felt the tingling sensation of bleach applied directly to the scalp. She’s considered a permanent wave -- more than once and during different decades -- and she’s gone from bombshell blonde to oxblood red to coffee-bean brown and back again happily. In other words, she’s been around the block. This isn’t her first deep-conditioning treatment, ya dig?
