biosilk and chi are basically the same thing they are both made by farouk sandrrra is right about the diversion in the salon/drug store industry, doesnt mean that the items sold in drug stores are always fakes, but they are black market products, sold by outside distributors to drug store chains? something like that, anyhow people like me, who rely on the sale of retail products in our salons lose out when they are sold in drug stores. like for instance we have a customer who comes in and buys up all the clearanced items we sell and actually we are doing a limit thing but its hard to enforce when people come in together, anyhow, he buys it all up for sixty to seventy off reg. price and sells it in his own store, or sells to small chains for half price..see what im saying? anyhow, thats the diversion issue, if that makes sense...as far as generic alternatives to chi or biosilk....i dont know any sold in drug stores but regis design line has a Silk Drops that is the regis version..and it sells for 10.95 so not too bad...honestly there isnt anything like chi silk infusions tho..lol..its one of my fave products. =)
