This product is amazing. My hair is medium brown to dark brown. I was expecting it to turn red, but it turned blonde! I was extremely happy. The product smells awesome, another plus. It was a strawberry blonde. But yeah, I suppose the color you end up with depends on your hair undertones. :))) HAPPY !!!

I have been paying for costly professional highlights for the past 20 years with very good results and LOTS of compliments. I happened upon this product at a popular drug/convenience store in the clearance isle and tested on the roots closest to nape. I had fabulous results then started using on crown for "touch-ups" between highlights. Eventually I began to spot highlight my whole head. My husband says the color is the best he's ever seen it and that I was a fool to have wasted over $16K (yes, $16,000 over 20 yrs) when I could have done this all along. My hair feels great and doesn't have nearly the damage (breakage/split ends) after being processed for hours. My hair was platinum until age 5 then a darker ashe blond with red undertones. With this product and a 3x a week use I now have maintained platinum with golden blond undertones and LOVE the color! The strongest validating point was when a hairdresser said she wished she could get this color!! Run ladies, don't walk to try this product!!!!

I love Sun-In! I've used it for about 3 years, since after Touch of Sun ceased production. It's a bit harsher than the old one, but not totally damaging. I am a dark brunette and get to a lighter dishwater blonde using this. I mentioned waiting on my order the other day and a colleague noted that she didn't realize I colored. I've also been asked what color I use to get it such a nice blonde. Due to the nature of the product, you get not a "flat blonde", but natural tones and highlights all with a few sprays and a blow-drier!

this product is great for lightning your hair. this product is specific for light brown hair or blonde shades, not for dark colored hair. after reading some reviews i can see that others didn't take the time to read that part of the bottle! i have sandy blonde almost brown and it works great and makes my hair look blonder!! DEFINATLY strand test!! ( better safe than sorry!!)

I've used this product for over a decade. I use it every summer to give me summery highlights. They last until they grow out. Very natural and looks great!

This product is great to use as a lightener. It's affordable and it works. In response to lizzie dancer- the reason your hair turned reddish was NOT the product. It just means your hair NATURALLY has red tones in it.

I just bought this in hopes of highlighting my medium-dark brown hair to give it some of those sexy Victoria's Secret highlights that the models have. I didn't think it'd work right away, but I just sprayed it in my damp hair, blow dried it and it's already got some noticeable lighter coloring where I sprayed it. I love this product and greatly recommend it!

You must be bright, otherwise it makes a mess. I like very much the result, even though when you keep it on it smells, so you have to wash your hair again before leaving the house.

Lets be honest: this is not meant to be used as overall color. I have strawberry blonde hair and normally pay upwards of [$]for highlights. I have used similar products before. In my opinion, if you use it sparigly and it achieves a great result. I use it 2-3 times every 3-4 months and deep condition and treat my hair well in meantime, it looks like I got a bit of sun and gives my hair a bit of a brighter look, I use very very little. Ok, so it is perfect salon hair but it is very very close and saves me over 1K per year.

I have really dark blonde hair that is really bright blonde in the summer when I'm out in the sun. But because lately I've had to be indoors or working nights my hair has been really dark. You don't even need to be out in the sun for this stuff to work, but it will take more time and application. I did not notice any "reddening" but my hair does have a slight red undertone. This stuff is really great because the blondeness does not look fake or dyed, its like how my hair was when I was a kid and always outside playing in the sun. I reccommed!
