maybe you can try.. but i somehow feel your hair quality is
around the same as mine (which is quite difficult to absorb
colours, I remember many years ago I buy blonde colour hair dye to
dye my virgin hair
, and the result turn out to be dark brown on
my hair)
if want 100% success, you can buy hair bleach powder and 9% or 12%
cream developer, but beware of timing cause the longer you let the
paste stay on your hair, the lighter it's going to become ( can
become bee hoon colour if leave too long and may be very damaging
to your hair)
but i don't think hair bleach powder can be found and bought easily
nowadays
the last hair bleach powder I used on my hair is WELLA
brand's
I somehow couldn't find it in the major chain supermarkets now
