Keratin Salon Direct Keratin Hair Treatment, 4 oz | Frizz Control, Formaldehyde Free, Salon Quality, Smoothing Treatment, Long Lasting, Cream for All, Frizzy, Curly, Dry, Damaged Hair

Main Highlights

  • DELIVERS SALON QUALITY RESULTS AT HOME, SAFELY and EFFECTIVELY: Keratin Salon Direct provides comparable results to traditional salon Brazilian-type keratin smoothing treatments when it comes to removing frizz and smoothing hair โ€“ but without the harmful chemicals. And, because KSD works from the inside out to strengthen and fortify hair, results with KSD mean hair is not only smoother, but also healthier looking and more manageable.
  • STRONGER and HEALTHIER LOOKING HAIR: Utilizes a process that we developed exclusively for salons which penetrates deeply into hair to infuse a unique blend of keratin, botanical extracts and vitamins that result in not only smoother hair, but a restoration of natural luster for overall healthier and more manageable hair
  • SIMPLE AND FAST APPLICATION IS EASY: Once completed, hair can be washed immediately, curled, or colored which means no strict rules or restrictions when the treatment is complete. No worrying about getting it wet once the treatment is complete. You can exercise, swim, and use pins, clips or wear a ponytail immediately. You can even apply color immediately following the KSD treatment!
  • CONVENIENT AND SAFE FOR YOU TO USE AT HOME: (1) Apply it to your clean damp hair (2) Leave it on your hair for the recommended amount of time (3) Blow dry your hair and then flat iron until silky. Thatโ€™s it! Style any way you want! Your hair will look like you just left the salon, and the gorgeous look and feel will last for months. Your hair can be curled or dried with a round brush for volume - the fabulous look only professional treatment can deliver!
  • KERATIN SALON DIRECT MISSION: We are the people who developed keratin treatments only available in salons! We are now making it available to use and apply in the comfort of your own home. We developed KSD so that salon clients could get a transformational, long lasting, and safe salon treatment that brings hair to its ideal, most beautiful condition without damaging the hair or using dangerous chemicals - without the need of a stylist or a salon professional!
