Magic Sleek Treatment in Scarsdale
$375+An innovative hair straightening system with wash and wear results.
Experience the next generation of hair straightening at Numi Hair Salon in Scarsdale. Magic Sleek is a 100% formaldehyde-free treatment that eliminates frizz, smooths unruly hair, and delivers sleek, shiny, manageable results that last up to 6 months, without the harsh chemicals found in traditional keratin treatments.
