Problem with ordering 1B is the knots behind the hairline are often visible. I have tried bleaching them but while the knots disappears they seem to be significantly weakened. Result: fullcap sheds to unusable status within a few weeks.

To get round this problem I'm considering ordering blonde hair next time them dyeing it myself to 1B colour using Clairoll 120, which I've used on other lighter brown units to good efffect.

My questions are:

1. is this a sensible option?
2. how long does the colour stay put?
3. if I want to leave some blonde highlights or streaks is it just a matter of wrapping sticky tape around some of
the blonde hair and dye the rest 1B?
