I love it!
Effects didn't last as long as advertised but to be fair,  it DEFINITELY works. It certainly creates a lot of fumes but if you've ever had a keratin treatment,  then you know that  THAT'S to be expected. This set offers A LOT OF TREATMENTS!  A LOT!!!  MANY!!!!!!...treatments come from this set!  MANY!  The instructions are spot on and different hair gets different results. After personal experience,  I opine that one should leave ALL available areas of ventilation open!  As a healthcare professional, I would suggest that one put a wet cloth inside of your masks (applicator and recipient)...with doors and windows open so that the gasses that linger will get trapped in the wet cloth if / when it goes beyond your mask or whatever is not drawn outside. It WILL!  NOW, that's certainly NOT meant to ring as a negative.  We all know that we all could die by driving or flying but we still do it everyday. This is a GREAT product!  It works beautifully!..."IF"...!!!! You follow the instructions.  Yes, there are fumes, but your  car does the same and we all know to keep the garage door open while it's running.  Same thing!  Good ventilation,  follow the instructions...beautiful results!
