Very helpful, responded to emails within a very short time and were very helpful and informative, great, beautiful quality genuine remy hair! I had a bad experience with 2 other online hair suppliers that sent me cheap, thin hair claiming to be remy, but as soon as I opened this package from Sophia hair I was immediately happy and grateful that once again I was going to have long luscious locks, the hair is amazing. Tangle free, soft and silky real thick human remy hair! Thank you! Will always be buying my hair from Sophia and am so glad I found them!
