I actually just had my styist use the Chi on me when she cut my hair - I asked what she was putting on it and she told me the chi stuff but said or sometimes she uses biosilk so I'm guessing there isn't that much difference - she's the type person who would say - I use this in this case, this in another.... I have always used the Biosilk and I didn't notice any better or worse with the Chi... I will ask her when she gets back from vaca...I wonder if the Chi is formulated to work with their flat iron?
I have the CHI silk infusion. I like it, but I don't use it much anymore. My hair is fine so it doesn't take much of the silk infusion. I just use a pea size amount otherwise it would get that greasy feeling.
Maybe it depends on your hair type? I have very thick very course hair so anything I use just soaks on in and you would never know I put anything on it - even the little bits of spray wax I piece with LOL.
I've used biosilk and flat ironed not a prob for me - I was told not to use too much (you can always add more) and not to get too close to your scalp.
^ yeah I have very thick hair as well it doesn't get greasy or oily when I put it on, but it does weigh my hair down a little. I love volume so thats why I am thinking about swtiching to chi,.perhaps it will take a way the frizz and flyways mostly and let me keep the volume. I bought it so I will see how it goes. Thankyou all for replying.
