I have a friend who I do hair for free for as she pays for everything when we go out! Anyway as I pay for the hair I've always bought the chespest crap on eBay for £40 as however much I say to look after them she just doesn't! I saw the hair yesterday. It's disgusting! I've bought some from SJK budget range and fitting tomorrow. Her hair type is really thin! Most wouldn't fit hair extensions to her I doubt but she insists and it's not damaging her hair she's had 3 sets in so far. My question is her hair is so fine that when she puts it up you can see all the hair at the root poking out. I really don't know how to explain that lol like you can see her scalp everywhere! It's not nice hair at all. And no matter how I do them they seem to show because there's not enough hair to cover them. She's fine with it but I'm not! I've been qualified 3 years and have done loadssss of all methods. I'm confident I know what I'm doing but advice would be good
