Hi anubi5.... As far as I can recall, `oils`as such are not recommended for systems ...not because they are not good for hair, but because they travel down to the knots and undo them ---- although if the knots have been sealed with knot-sealer, I guess there`s very little chance of that happening.... so far, none of my systems have ever felt coarse/processed on arrival....the stylist often remarks on how soft the hair is [ and did so again yesterday when cutting the fullcap].... It`s hard to say why this hair is breaking for you ..... I can`t see why/how the factory would over-process hair on a particular batch but obviously i`m totally ignorant of what can happen there on any given day.... I`d just advise anyone who thinks the system hair is very coarse etc. on arrival, to just contact John directly rather than go ahead and wear and then find you`re having problems.....I hope the oil will help..let us know as time goes on...cheers, Paul.
