Does this product eliminate the need for an additional leave in conditioner and a heat protecting spray?

Hi Denise, This is really up to you. The b3 Ionic Extension Refresh is formulated to blend natural hair and extensions and also repair damage. If you are looking for extra deep conditioning this should not act as a replacement, we would recommend the b3 Instant Restore & Protect Reconstructor for a deep condition. Again, this will prevent and repair damage but it should not be used in place of a heat protectant.

Can I use for second day styling on dry hair? Does this work as a heat protectant?

Hi! This product should be used on clean damp hair as a cleanser to detangle, revive and seamlessly blend natural and extension hair; it is not meant to spray on dry hair. It will not harm your hair but there will be no benefits of spraying it on dry hair

Is this product authentic? I spent a lot of money on my extensions and I don’t want them ruined by knock off items.

Hi! Yes these products are authentic Brazilian Bond Builder products.
