Yeah I agree with your previous post, I've sourced, in other words found good quality hair from several hair extension factories but to be completely honest you need atleast $50k to have them perfect, also if you do decide to proceed and import the hair the factories won't manufacture hair for you in small quantities, you need to order thousands of packets, decide how much hair to put in a packet and you also need to source the beads, tape replacements and etc from the same factory in some cases, which all needs to be bought in huge quantities.
I was about to do it but realised I think for me at this minute is too much of hard work to try and make work.
The only time sourcing and importing hair will work out and be worth while for your business is if you're planning on wholesaling them.
Other than that, you need to keep on top of your stock levels because you don't want angry clients waiting weeks for hair.
All in all, the extension business is good money and wholesaling hair is amazing money but you NEED a reputation which can take years and years to build.
I'm happy to help with some info if any if you want to inbox me.
