Hi again rw80..... time -difference between here and where you are means I`m only getting back to this now as I was sleeping ...... seems like ``lovehair`` has answered all of your other questions anyway....... very helpful he is too ..... again, just to repeat...be aware that you`re best off not to go for the ``finished / desired look`` initially ....some knots will be weakened by the Nair, but not enough so that they ` give` immediately ...but they will give way/fail over the next few days as you brush, so more hair will shed out , and the system will look thinner.
Don`t worry about the ` timing` ......Nair won`t damage the lace...... just take your time, and do a specific [small] area at a time, rather than trying to do the whole lot..
All Toplace systems are made with human hair...the only synthetic hair is gray..this is because if /when you want /need to color the hair, as it oxidises over time, the synthetic hair doesn`t ` take` color ..it remains gray ! .......best wishes with it ...wearing can be a steep learning-curve ..these early ` issues` you`re having are all part of the learning-curve and will help you to formulate your specs. for a custom-made system......all the best !
