Power-packed with a unique nourishing oil blend and our C3 Custom Care Complex, Crystal Serum improves the hair's texture and brings extremely damaged hair back to its optimal healthy state. This restructuring treatment is most effective on hair that's been damaged from daily styling, over-processing or hair that may be over-bonded from multiple color treatments.

Crystal Serum is also the first step in the two-step, professional in-salon treatment, Crystal Cashmere System.

  1. Cleanse hair well using Clear Haze Universal Shampoo. If heavily soiled, repeat cleansing. Rinse hair thoroughly and towel-dry excess water. 
  2. Depending on hair's density and length, pump 1 oz. / 30 ml of Crystal Serum into an applicator bottle or color bowl. Emulsify product between hands to activate thermic reaction. 
  3. Using your hands, apply in 2 inch sections, starting 1 inch off the scalp and working through the ends for complete saturation. Start at the nape of the neck and work your way upwards towards the crown and sides, finishing at the front.
  4. Comb through to evenly distribute and to avoid over saturation. 
  5. Process for 15 minutes* 
  6. Rinse thoroughly and towel dry excess water.
  7. Style hair as usual.


  • If heavy product or mineral buildup is suspected, consider a demineralizing treatment prior to performing Crystal Serum in order to achieve optimum results. 
  • *Processing time can be increased for additional benefits on extremely damaged hair. Use your professional judgement based on your client's level of dryness. 
  • Crystal Serum is an ideal choice for hair that is potentially overloaded with bonding treatments or over-proteinized, causing hair to be brittle and dry. This treatment will aid in restoring the hair's suppleness. 
  • Crystal Serum can be used as an add-on service post texturizing and perming services to restore the hair's elasticity by hydrating and nourishing, for an overall transformation.
  • If hair is in need of strength, move on to step two, Cashmere Fusion Restorative Treatment.
