DD has been obsessed recently with having blonde hair. She particularly wants to achieve a platinum blonde look. She has used various dyes in the past, but the one she persuaded me to use on her hair yesterday was l'Oreal Preference Extreme Platinum. She has very strong, thick hair, but it appears very damaged now. She admits now that this was the third time that it has been dyed in three weeks.
She hasn't been able to comb/brush it as it appears that clumps of hair are coming out. She used the conditioner after the dye, as usual, then I told her to use loads of the same conditioner again. Hair is still very brittle.
Does anyone have any tips on how to repair this? Or any advice you can give at all would be greatly appreciated. Many thanks.
