I've been using some of the John Frieda Go Blonder products for a while now so I thought I would review them for you.
The best thing is that is actually works. I can't really show you any before and after photos because its hard to see in photos due to different lighting, but you can tell it works because when your hair grows you start to get visible roots. Its a gradual change in colour though, you may not even notice any difference after the first spray but I found after I had done it a few times my hair was noticeably more blonde. Note - I wouldn't say it was particular lighter in colour, its more that it becomes a brighter more vibrate yellow colour. I love this spray, its amazing. I've tried things like honey masks and lemon lightening before to lighten my hair but it has never been very successful for me. Whereas this really does work. The only negative is that the bottle really is very small. Its not going to last more than 5 or 6 good sprays.
The bottle claims the spray can be used for all over lightening (which is how I used to it), to create highlights or to blend in roots if you have already dyed your hair blonde. To create highlights would be very difficult and would take a lot of work to get it right so I wouldn't recomend it for highlights. However if you have dyed your already light brown/dark brown hair blonde it would be a great way to blend in your roots.
Obviously though the spray has got hydrogen peroxide and other chemicals in which some
people do not like using on their hair. It also requires applying heat to
your hair which can be damaging. However, you only need to use
the spray a few times so the damage using the chemicals and heat should
not be too bad. Its worth it for me anyway.
I do really like these products. Obviously they are only going to work if you have blonde hair to start with. My hair is naturally a dark blonde, its been getting darker as I've got older which is why I wanted to try these products. I've heard they may also work on light brown hair. From what I've seen, there isn't really any other products like this that you can get in a regular pharmacy. I suppose something like sun-in is similar to the spray, I am yet to try this out as there is very little sun where I live (its like permanently cold and raining in the north of England). I haven't heard too many good things about sun-in anyway.
If you don't have blonde or light brown hair, this post is pretty irrelevant to you, however there is a similar product by John Frieda for darker hair called Brilliant Brunette which claims to bring out rich, multi-dimensional brunette tones and add shine. From reviews I've seen its meant to be quite good for making brunette hair richer in colour. Have you tried any of these blonde/brunette products? Let me know what you thought of them :)
