They say in the instructions accompanying the product it must be done in a ventilated room, if you can do it in your garden, it would be even better.
During application, I wondered what would have happened if I threw asthmatic, or if I had a problem in the eyes ...
The product is really too strong (step dryer and straightening iron surtt) Me, I put more than 4 hours before finishing the application, I had to breathe and wipe my tears every time.
For the result, I admit that it is good! I am on the 3rd day of the application (not washed), and they are really sweet, I have very dry hair, kind Maghreb, and here I am really happy with the result
Will I redeem? for the result, and for the price of the product, definitely yes!
Would I recommend it? bin! ... In case tt not for people with breathing problems and sensitive eyes!
