The melanin problem no international brand addresses
Indian hair carries a higher concentration of eumelanin, the pigment responsible for black and dark brown tones, than the hair types most global colouring formulas are calibrated for. This matters because lifting dark pigment requires more developer strength or longer processing time, and most off-the-shelf international brands set their baseline for medium-brown European hair. The result: Indian hair either comes out with a brassy, orange-red undertone when lifted, or requires a second bleaching session that the packaging never mentions.
