Hey! I'm new to this site (although have been here before just reading posts) and have found it quite helpful! It's funny how we are all normally so protective over who our suppliers are! To be honest, I've been dying to find some good suppliers but haven't wanted to come right out and ask anyone!
I have been doing various methods of hair extensions for years, but recently went on a refresher course with Belle Hair Extensions (who I do NOT recommend btw) and they give you no help what so ever in finding suppliers, the suppliers they recommend are honestly rubbish.
Anyway, after doing a lot of homework and trying different suppliers, I now use a few different suppliers, depending on what the client wants. I haven't found 1 supplier who supplies everything that I need, that is why I tend to switch around.
Anyway, the cheapest I have found (and would only recommend for darker shades) is hairxtensions.co.uk. They only last around 3 months and are chinese remy, but are perfect for clients on a budget who only want extensions short term. They are also very reliable and have excellent customer service. I only use nail tip from them.
For Indian Remy on the cheaper scale, I use Melissa at SMP Beauty. She only does 0.5g hair though, but it is decent quality Indian Remy lasting around months max. I get nail and stick tip from her.
For better quality Indian Remy Nail, Stick and Wefts I use hairextensions-shop.com. They have two different hair types, Elite and Premium. Excellent quality and good price also.
I have recently placed my first order from Hair Planet, a 20" remy weft. It looks and feels amazing, same thickness top to bottom. Time will tell how good it is! I also want to try Foxy for a change, but haven't ordered from them yet.
And of course I will be trying hair from the suppliers mentioned in this thread!
