New formula does not work the same as the original, maybe it's the purple they added which I don't need, but it does not lighten nearly as well as before. Glad the smell is not as horrible so that improved. I've used the original since the pandemic! Very sad.... have to find something else now...

Excellent product if you strictly follow the instructions, I make sun-kissed just with 3 usages,the only negative make the hair very freeze

⭐ 1 star – Completely ruined my hair I used the John Frieda Go Blonder Lightening Spray while I was on holiday, thinking it would gently lighten my hair. When I returned, I told my hairdresser that I had used the spray because I normally have highlights done and have never had an issue with my hair snapping. My hairdresser carried out a strand test before doing my highlights, as she always would. The strand test snapped because of the condition of my hair following the use of this product. As a result, my hairdresser was unable to do my highlights at all. I have never had this happen before, and I'm absolutely devastated that a product I used expecting to lighten my hair has left it in a condition where I can't even have my usual salon treatment. I really wish the packaging made it much clearer that using this product can potentially cause such serious problems when you subsequently have your hair professionally coloured or highlighted. I will never use this product again and would strongly advise anyone who regularly has their hair coloured or highlighted to think very carefully before using it.

bought this and used for a few months and it worked but it damages deep into your hair permanently and you cant see it which is worse and there was no warning on the bottle to say u cant get highlights done because it will cause a bad chemical reaction and make your hair dissolve and come out and be absolutely fried and not the same( use if u want to damage ur hair deeply overtime)

Used as intructions show, made the top o my hair very orange after a month!

Ruining my hair!!!! Do not use! Bleaching effect and dry damaged hair

I haven't bought John Frida hair lighter in a while, have been using a different one and wasn't really getting the results. Last time I used it it was quite good so I decided to switch back and bought two bottles online…. Wow they are so tiny and could not for the life of me Figure out how to get the bottle to work and spray.!!?? why are they using this strange nozzle? I ended up having to break it and putting it in a Sun in container! Why can't we just use easy sprayers? So frustrated and I haven't even used the product yet….

The number of people blatantly admitting they didn't follow the instructions at all and then leaving 1* reviews is crazy! (i.e. using on brown hair, already bleached hair, using over 10 times). I have very fine dark blond/ light brown hair and used this spray as an alternative to balayage as dyeing it many times has made my ends incredibly dry and damaged. I used on my grown out roots and it works absolutely perfectly, matched my roots nicely to the dyed hair whilst still keeping it soft and in good condition. It came out slightly brassy at first but looks wonderful once I used purple shampoo. I will absolutely continue using this once my roots have grown out again, and love it as an alternative to expensive/ damaging salon trips. It's unfortunate how many people don't bother to follow the instructions at all and then leave bad reviews, however I do think that they should make it more clear that you cannot necessarily go and get your hair dyed again after using this, as it seems that many people have been disappointed by that. If you are on your healthy hair journey, committing to no more heavy bleaching and have dark blonde/ almost-blonde hair, I would really recommend this product! Allowed me to still have the blonde look whilst taking care of my hair and is such a great price.

Turned my blonde hair ginger don't buy absolutely awful

I had virgin black hair and I know that it won't make my hair blonde, I just wanted brown hair. It did get somewhat lighter. Only kind of brassy but blue shampoo helps if you don't like it, so if you want brown hair go for it. No hair damage but do not bleach hair after using it if you do not want melted hair. I would buy two of them since it runs out fast for longer hair.
