Honestly speaking there is not a formal standard in current Chinese hair market, as a hair factory in our experience the remy hair about 10 years ago was the best quality hair but things have been changed recent years. For the rapid price rise of the hair material many manufacturers began to use non-remy hair or no machine remy to low the cost. Obviously that kind of hair is not high quality even it’s called 5A, 6A,
even 7A or more A means nothing, it’s just a kind of trick. So when you want to buy high quality hair don’t ask the vendor how many A it is, ask the them how could they guarantee the hair? How long it could be lasted? Acid bath all not? Full cuticle or not? For seabeautyintl we guarantee our Luxury European style virgin cuticle hair could last 1-3 years with healthy cuticle intact, no acid bath or harsh chemical, only green processing with gentle and slow treatment!
