Use Directions

One ‘n Only Brazilian Tech Keratin Smoothing System creates beautiful, shiny hair – smooth as silk!

  1. Shampoo hair twice using Keratin Pre & Post shampoo. Towel dry to remove excess moisture.
  2. Run a wide-tooth comb through the hair before applying keratin smoothing treatment.
  3. Section the hair into 4 parts. Shake bottle well. Pour Keratin Smoothing Treatment into a bowl and stir with brush. Start with 2oz–3 oz. and add more treatment as needed. Wearing gloves is recommended.
  4. Starting at the nape, part the hair into 1" sections. Using a tint brush, apply cream 1/4" away from scalp; apply from scalp to ends on each section.
  5. Comb treatment through each section with a fine-tooth comb, making sure it is evenly distributed.
  6. Continue the process until entire head is treated. You can then use a wide tooth comb on the entire head to ensure even application. Start timing when treatment application is complete on entire head. Reference instruction booklet for timing.
  7. Rinse hair thoroughly and gently shampoo again with Keratin Pre & Post Smoothing Shampoo and remove excess moisture.
  8. Apply Keratin Leave-In Conditioner and comb through to detangle hair.
  9. Blow-dry hair 90% on a medium-hot setting, directing air flow from scalp to ends and using fingers or a brush.
  10. Using a flat iron, start at the nape area. Working on 1∕8" sections, slowly pass the iron from root to ends 4–5 times, infusing the treatment into the hair. (Flat iron should be at 400°–410°F for color-treated or highlighted hair and 450°F for normal or coarse/resistant hair). Repeat on all sections of hair. It is recommended not to shampoo hair for 48 hours after treatment. If hair gets wet or damp during this 48-hour period, blow dry immediately and flat iron on medium heat. It is also recommended that within this 48-hour period, hair be worn down and no clips, pins, ponytail holders or headbands.
