I have what seems to be the entire Infra line. I have the shampoo, conditioner (treatment), silk infusion, keratin mist, 44 iron guard, shine spray, holding spray....
I think that's it.
The shampoo is okay. I haven't noticed anything special.
The conditioner (treatment) doesn't provide a whole lotta slip, so I have to follow with a moisturizing conditioner. It's supposed to be good for hair that is flat ironed often and that's mine, so...
I'm absolutely in love with the silk infusion.
I use the keratin mist after just about every shampoo regardless of what line I'm using. I haven't seen anything benefit wise yet, but I figure the extra protein can't hurt.
I use the iron guard before blow drying. It doesn't weigh my hair down or make it feel coated or anything.
The shine spray doesn't have oil in it to weigh my hair down so I really like that.
The holding spray works well, but I don't use it too often.
I just started using this line about 6 months ago and I don't use it exclusively, so I'm still finding the good in all the products. I will say that my hair is very light and bouncy and smells great after I use the entire line in my wash regimen.
