Cystine Hair Smoothing System
Manageable, beautiful hair is possible with the Cystine Hair Smoothing System. This formulation system has been proven to make curly and unruly tresses shiny and sleek. The system contains Crodasone™ Cystine and other proteins to help hair look and feel healthy.
Additionally, this system leaves hair easier to style and in many cases requires less time to style. With a salon inspired straightening treatment and protein leave-in conditioner, and a shampoo and Keravis™ hair strengthening conditioner designed for use at home, the effects of the Cystine Hair Smoothing System can last for 4-5 weeks, depending on the hair type.
Instructions for use:
- Shampoo and rinse hair twice with the Cystine Smoothing Shampoo
- Towel dry to remove excess moisture
- Starting at the nape of the neck, use 3.5cm sections of hair and apply the Cystine Smoothing Treatment, starting at the base through the ends
- Repeat procedure, saturating the entire head
- Rinse after 30 minutes and wash with Cystine Smoothing Shampoo
- Towel dry to remove excess moisture
- Apply the Protein Leave-In Conditioner
- Blow dry hair until 90% dry, then go over the length of 3mm wide sections of the hair 3-5 times with straightening irons
- Use the Cystine Smoothing Shampoo and Keravis Hair Strengthening conditioner exclusively as needed after treatment
To exploit the trend for biomimetic proteins, an alternative version of this system is available containing Croda's diverse range of Keratin proteins, called Keratin Therapy. View the Keratin Straightening System here.
