It's possible to buy loose hair (rather than hair that is pre-attached to a weft) for much cheaper than packs of hair wefts. Although it is possible to make your own hair extensions using loose hair, the process is very difficult and time consuming, so it is not recommended.
How much does it cost to make your own hair extensions?
Type Average Cost
-------- --------------
Sew-in $275+
Weave $100 to $600
Fusion $200 to $1,000
Glued-in $300 to $500
