Scoop out a boat section from the base of the scalp. Apply Godrej Professional's No Ammonia Pre Lightener mixed with 20 VOL in the ratio 1:2.
Divide the front section of the head into three, which will give you two temporal sections on either side.
Mirror this on the other temporal section.
For the overhead apex section, use Godrej Professional's No Ammonia Pre Lightener mixed with 20 VOL in the ratio 1:2 until you achieve the level 9 undercoat. Follow with mild shampoo to stop the processing of the pre-lightener.
For the root touch-up, use shade 5.1 from Godrej Professional's No Ammonia range, with 20 VOL. Apply on to the roots and then feather it out to about 3-4 inches into the hair length to create a connection with the rest of the pre-lightened lights.
While the roots are processing, apply Pearl Blonde with 20 VOL 1:1 ratio from mid-lengths to the ends. Process this for 15-20 minutes.
Wash and condition the hair with Godrej Professional Colour Lock Shampoo and Mask.
