Cysteine Plus Straightening Kit for Natural & Color-Treated Hair Tone 1–7, 150 ml | pH Protein Lab

Step 1 Wash the hair twice with a neutral shampoo to open the hair fiber, then dry thoroughly.

Step 2 Divide the hair into four sections. Wear gloves during application.

Step 3 Apply a generous amount of pH CYSTEINE+ to the hair, staying 0.5 cm away from the scalp, and comb through with a fine-tooth comb. For damaged hair, apply pH CYSTEINE+ only up to the start of the damaged area, and gently pull the remaining product on the comb toward the ends.

Step 4 Roll each of the four sections from the ends toward the roots into a coil (snail shape), while applying gentle tension, and secure with a clip. Recommended processing time: 60–70 minutes.

Step 5 Rinse the hair thoroughly with water only.

Step 6 Dry the hair completely.

Step 7 Straighten the hair fiber using professional straightening techniques.

Step 8 Wash the hair with salt-free shampoo, then apply a salt-free mask and leave for 5–10 minutes. Rinse well and dry.

Step 9 Finally, apply a treatment serum to the hair.
