HairDirect is basically an internet salon. They offer the same services and products as a brick and mortar salon at about half the price of a unit. They sell the same hair as anyone else, except you pay extra for a haircut. I used HairDirect as my first online hair supplier, and the results were mixed. The first unit I got was really good, but the reorder on the same specs wasn't even close, even after 3 tries. The hairtechs are very nice, and their return policy is excellent. If you need some hand-holding support in your DIY hair adventures, this is the place; but you will pay extra for that support. Their product line is the most varied, and they carry products you see nowhere else. I don't know if my experience was typical, and I rather suspect it's not, many wearers swear by them. But you will pay extra, and if that's an acceptable risk, give them a try.
