I placed and order and now I am waiting to arrive. Obviously, I have the regular set of doubts of most first-timers. however, there are three other things I wanted to ask:

1. I plan to do highlights after attachment. Can I be fairly sure natural hair will colour the same way as unit hair (hair-sample matched)?

2. The frontline – I have seen many picture on this forum and some of them look great, but many of them look like the hair at the front line come from the back, forward, parallel to scalp, and then at the very front they just bent upwards. I do not think it looks natural at all. Rather like some dense comb-over. So, on the hairline, can you actually see hair 'growing' from the scalp?

3. Knot bleaching - I read somewhere that it was necessary years ago but not anymore. Still, I found some posts of people that are bleaching knots of their new units. What's the deal with that?
My unit is supposed to be 75%, dark-ish blond.

I look forward to input on these issues.
