I have been doing hair extensions for 5 years and although Great Lengths is the best quality out there it's not affordable for most. I am certified with both Great Lengths and So Cap. I am offering So Cap hair extensions 3 Bundles for fullness for $400 and a full head (5 bundles of 18 inch) for $650. (Typically 5 is enough but for extra thick hair more may be necessary at an additional charge) Most salons charge $1200 to $1500 for this service. Prices include hair and cut.
