Does this product cause brassiness in blonde/ highlighted hair? I've had two experiences with keratin treatments and both caused some degree of brass

Most keratins will cause the hair color to fade or become brassy. Mostly reddish undertones. It will subside but you should do a toner 1-2 weeks later if it does not change. Blondes are okay if they are lifted past orange. Just color treated hair. More so brunettes/light brunettes. This product however is not real. The consistency and smell is different and it shows in the results. Fake. I contacted the provider expressing my issue and was not responded back to. Beware. P.s Licensed professional.

what is the shelf life of this keratin?

0 days. I would HIGHLY recommend not purchasing this product. Had it applied at a high end salon in NYC and it made my hair fall out. General thinning and then a large bald spot. Took months of steroid injections into my scalp and supplements for my hair to start growing back. After sharing my story online I learned that I am not the only one who has experienced this adverse reaction. Several salon owners contacted me to let me know that they are taking legal action for damage caused to their clients from using this product and the corresponding flat iron. Take caution.

is this formaldehyde-free?

NOOOO!!!, DO NOT BUY THIS PRODUCT,,IT HAS DESTROYED MY HAIR. Yes, I am that serious. Amazon shouldn't even support this supplier.
