A leader in keratin smoothing
In the past formaldehyde has been the main ingredient in keratin smoothing treatments for years, but now there’s a wholly holistic approach to keratin smoothing—Keratherapy’s 100 percent Formaldehyde-free Pure Renewal Plus! With zero Formaldehyde, this groundbreaking formula removes up to 90 percent of curl or wave, eliminates frizz, adds shine and drastically improves the manageability of tough tresses without those familiar offensive odors!
Full of essential nutrients and proteins, the reparative Pure Renewal Plus packs a stronger punch compared to its Pure Renewal predecessor by offering maximum curl and volume reduction without causing permanent structural change to the hair for up to 12 weeks. This treatment works with color-treated tresses, is safe for all hair types whether normal, coarse or resistant, and—being Formaldehyde-free—has an incredibly fast and easy application time with zero down time!
