Keratin

Starting at $330
Reduces frizz, improves manageability, and softens the hair, making daily styling easier. Results and longevity vary with your hair's starting condition and home care.
For the keratin and express blowout, these are both smoothing treatments; this is not meant to be a straightener or relaxer. These types of treatments are meant to “eliminate frizz, increase manageability, repair damage, and leaves the hair noticeably softer with luminous shine.” (keratincomplex.com)
