B3 Hair Treatment & Pure Essence Oil (after-care)

Reaction Treatment B3 & Pure Essence Oil. During your in-salon iStraight straightening service in addition to many beneficial products they will be using on your hair to ensure a beautiful result your treatment will end with two professional strength products that you can take home as an addition to your other home aftercare treatments. You can also use both products if you do not chemically process your hair but for best results, we recommend them if you do.

B3 Hair Treatment (aka, Reaction Treatment B3)

The first one is B3 Hair Treatment made with keratin, silk, collagen, plus 14 various natural oils, extracts, and proteins that will nourish your hair from the inside out.

Pure Essence Oil

The final jewel to our aftercare products is a luxurious Pure Essence Oil. This oil is so light it instantly absorbs without creating an oily feel and leaves you with soft, manageable, and incredibly shiny healthy hair. This oil is excellent for protecting the cuticles and will prolong the straight, polished, silky, beautiful results of your iStraight treatment. If you do not have a straightening procedure done but use a blow dryer and iron it will also act as a heat protectant.

Pure Essence Oil is made up of such low molecular weight ingredients that it easily washes out with your next shampoo. Other brands usually contain silicones that build up over time and end up dulling your hairs shine although it may look shiny at first.  The key ingredients in this luxurious product are Argan Oil, Jojoba Oil, Olive Oil, Grape Seed Oil, and Rice Oil.

*None of the Innosys-iStraight Hair or Hydration aftercare products are tested on animals. Our whole line of products is cruelty-free.
