I did bleach the knots & it did not take long so I recommend 3-5mins max or less. I used a 40 developer with the purple powder pak. Also did not pluck the frontal bc it was pretty good for my liking! Also be gentle with frontal it does shed a bit but not excessively. And last I do not use ANY products on this hair but water bc it curls up naturally to a very pretty curl pattern.
