Sun-In Spray-In Hair Lightener, Tropical Breeze - 4.7 fl oz

Works great. I noticed it lightened my hair in about three days.

as a natural blonde i love that it lightens my hair and does it good if you’ve never died your hair before! definitely keep your hair moisturized because it does make it dry

Great hair lightener that works with your hairs down natural high lights.

I have been using Sun-In spray for decades. I have very dark brown hair and I like the streaked look. I do get streaks added in the winter but in the summer, I can usually achieve some nice looking lighter brown streaks with Sun-In. I saw some pics of people who went from black hair to almost blonde and that could NEVER happen to me unless I poured a bunch of bottles on my head and basked in the sun for hours several times or used a hair dryer and repeated the application process several times..This does contain peroxide which is what lightens the hair but it is in a much milder concentration that what hairdressers use. It still can cause damage though so be careful and watch for signs of split ends and breakage..The tropical Sun-In has a decent scent. I didn't and don't mind the original either. I have heard that this one is more powerful than the lemon scented one. I don't know if that is true or not but this one seems to work a bit faster for me..I just spray my hair before I go out in the sun or sometimes I will spray then blow dry. The heat activates the peroxide which speeds up the lightening but you don't need heat for this to work. It's the peroxide that lightens. I only get streaks that are a few shades lighter but that's fine with me. I don't see much damage when I use this although my hairdresser warned me that I would be ruining my hair if I continued using it. After 30 years of use, I think I know my hair better than anyone and, used properly, this doesn't dry it out or break it .It is best to use on virgin hair - hair that has not been colored or chemically treated.It's easy and does work for streaks but do know that if you have dark hair, you may get a red or brassy tone rather than a blonde or light brown. I often go through the red phase before I get to the lighter brown color/dark blond because I have red undertones. I think this works best on blondes and those with light hair but it does a good job on dark hair as well but generally more subtle. Use it sparingly until you see the results you are going to get and if your hair dries out from it. It all depends on the condition of your hair and the undertones. Wash it out and condition hair well to avoid dryness and damage and you will get a nice beachy looking head of hair. I have never been able to turn my hair a completely different shade using this product though. For that,I would go to a professional.

I use sun-in in every few months over the top of my hair and blast it with the blow drier. I have very, very dark, cool toned hair, but the sun lightens my ends and makes them almost auburn. So Sun-In every so often helps me bring the warmth further up the shaft, making my hair look more dimensional and cohesive. It looks super natural and my hair looks glossy and healthy. Will repurchase.

It seems to work ok but is not lightening my hair the way I wanted.

Works as expected.

I got this to use to slowly, subtlety lighten my hair without the rest of me getting all sunburned. Most lightening products abuse my hair and leave it dry, brittle, and angry. This stuff is amazing- my hair is happier, silkier and smoother when I use this than when I don't. I didn't blow dry my hair like it says to- but I still got decent results at a nice, slow pace. No complaints whatsoever.
