cost of a hair system is high

cost of a hair system is higher than you think.  This is what one poster wrote: cost of a hair system is high

The one clinic I’ve found near me has hair systems starting from $900 (!) and it’s assumed i will need 3 of those per year. Then I need a cleaning of the hair system and re-attachment every 3 weeks costing $130 each time.

Annual cost is thus: $2700 for hair system itself + $2300 for re-attachments = $5000!! This is not including all the hair styling products and special kinds of schampoos needed (which is not cheap). What the heck?? Why is it so expensive?

I heard you can buy cheaper from online stores but that it’s basically a gambling not getting different kind of hair or a damaged system etc. Anyone with experience?
