Bleaching Powder
It should be noted that by dechlorinating the hair for the first time, by removing the hair pigments, the texture and color of the hair changes. With the activation of chemicals, dechlorination powder naturally generates heat. Because the hair roots are closer to the head, the hair roots are warmer than the rest of the hair. Therefore, it is likely that the roots become lighter than the rest of the hair due to the heat released from the scalp. Therefore, it is better to use a weaker formula on the roots when dechlorinating the hair to ensure a uniform lightening of the hair.
