Sun-In Hair Lightener Spray, Lemon, 4.7 Ounce

I have used Sun In for many years on and off. I recently was using the Tropical Breeze variety and it worked great on my dark brown hair. I didn't even realize how much lighter my hair was getting until I compared pictures from before I started using Sun In and after. The Lemon kind is fine as well. Some say the Tropical Breeze has more peroxide and is "stronger". I haven't really noticed much difference between the two. I spray Sun In on my dry hair and just leave it in. I don't even blow dry it or go in the sun half the time. Sometimes, I spray it and blow dry. When it gets warmer, I will certainly go out in the sun with Sun In in my hair because that will speed up the lightening. I like lighter brown hair but it gets damaged when my stylist does it. I get no damage when using Sun In. It's gradual but that's fine with me. It looks natural too. The only thing is that I don't really get highlights. I get all over lightening. It's probably because I don't spray just a few strands separately but just spray it wherever. Obviously where I spray, it will lighten. I have seen pictures of black haired women going blond just from Sun In but that wouldn't happen with me. It just takes me down a few shades which is all I want. In all, it's a cheap and easy way to lighten even dark hair. I have had my hair professionally highlighted and still used Sun In to brighten my look. It CAN turn a bit brassy at times. I recently dyed over my hair with a dark blonde hair color which toned down the brassiness but didn't lighten my hair overall since you can't go from dark to light without bleaching or peroxide. So now, whenever I see that my hair is looking a little yellow or brassy, I will just dye it with the dark blond and I am good to go. I'm pleased with the product and have been for decades. NOTE: The photo I attached is me at my darkest natural color. The second photo is after three bottles of Sun In and sun exposure. It was starting to get brassy so I eventually toned it down but you can see it really does lighten! I do think though that the second picture makes my hair look a bit lighter than it really is. It really depends on the lighting.

At the beginning of the summer, I thought about Sun In that I used when I was a teenager so I searched and found it here. It's very simple to use. No messy at-home hair color kits. I did not use the hairdryer method as suggested. I sprayed it on when I was going to the beach or kayaking and let the sun do the work. It slowly lightens your hair over time so you would need to be patient, but the results after several uses is great. Will plan to use it again next year.

Definitely will lighten your hair. I used on vacation to help lighten and hide grays. Just be careful and don’t use TOO MUCH. Overall it did what I wanted it to do. And no damage to my hair.

I am naturally dirty blonde with long hair. I use to get highlights every couple of months and it got so ridiculously expensive, I stopped 6 years ago and haven't had my hair professional highlighted since. My sisters and I put lemon juice in our hair during the summer and I am very happy that I found a product that provides the same highlights, if not better, year around. Winter time is always tough because my hair gets darker and I'm tempted to go to the salon, but with this product, I will never be tempted again! I think the trick to this product is to start slow, very slow. I purchased a bottle of the tropical and started with spraying a little on my fingers and adding it to a few strands around my face because I was afraid that it would damage my hair or turn it a funky color. I would do this every other time before I would blow dry my hair, and I really liked the results. No damage and no strange, unnatural color - I also should mention I use this when my hair is towel dried before blow drying. I then got a little braver and started to directily spray it on small sections on the top of my hair, framing my face and then running my fingers through that section to distrubute it. I didn't saturate with the philosophy that less is more. The top half of my hair is now really, really blonde and I am asked all the time if I get my hair high lighted. When I reply with Sun In, people usually do not believe me. I really did not use very much each time, and one bottle lasted my a year and a half. I was shocked it lasted me that long. It is a very good investment for the price. Now my next step is the under layer of my hair. It has gotten significantly darker now that it is January and there is a definate difference in color from the top layer of my hair. I've started to spray about 3-5 times around my bottom layer, towards the roots, and I am fairly confident that I will get the desired results. Through my experience, the key to this product is patience, patience, patience - less is more! I have always heard negative things about Sun In my whole life, but all of those myths are busted. I ordered one in lemon and one in tropical and that should last me a few years. I'm very glad I took that chance and started to use this product and I really hope they never stop selling it!

I used to pay thousands every year to get blonde highlights done. But the pandemic came along and changed things. So I tried this stuff from the 80s. And now I’ll never go back to the stylist for color! Note that I am of northern European heritage and was a natural blonde as a child, but my hair darkened as I grew up. So that’s why this stuff works for me. I understand that it turns natural dark hair a lovely shade or orange. I apply it to damp hair and then go sit in the sun for a bit. And when the sun isn’t available, I hit it with a hairdryer on high heat and low speed. The sun does it best, but the hairdryer technique does successfully lift my color a few shades and gets me through winter. When I first started, I applied it heavily over several inches of growout. It took a whole bottle to lift the roots to match the treated hair. And for a while, it was pretty brassy / orangey. I kept going though because I learned that the grassiness just meant I hadn’t lifted it enough yet —and I am glad I persisted. After over 2 years of use, I have lovely highlights that rival those I used to pay thousands for. I just hit my part and about 3 inches on each side, and then the new growth around my face. I prefer to use the sun but will use the hairdryer in the dark of winter. When I use the sun, I apply every 2-3 weeks. And with the hairdryer. I apply weekly and run outside anytime the sun shows itself over the winter.

I have brown hair, it isn't dark but it's not light either and I also have grown out highlights left over from last summer. I had really high hopes for this product because I was hoping it'd work just as well as going to the salon. As of now I've used it 3 times. I'm starting to tell a slight difference in the shade of my hair color. It's very subtle, and frankly, I think I'm the only one who can tell. It hasn't done anything to my already color treated hair (I was terrified it'd make orange streaks through my hair where old highlights were left behind) which is really good but the color difference is not as obvious as I was going for. However for the price, I think it is a fine product & maybe if I was a natural dirty blonde it'd work better and give me the color I was trying to go for.

As I neared my 44th birthday, the gray hairs were starting to come in. I have always hoped that when the gray struck, I'd be an enlightened woman who didn't feel that she needed to hide her gray. My hair is short and curly, so I wash-and-go. I don't wear make-up. But, alas, as I was looking under the fluorescent lights in the bathroom at work, I did not like seeing those gray hairs popping up. Where I live, many woman have kids at age 20. People already mistakenly assume that I am my children's (ages 11, 9, and 8) grandmother. And that's without gray hair. So, what to do? With 3 kids and a full-time job, I can barely make it to the hairdresser's every 3 months for a quick cut. I really didn't see how I'd fit in a color. And then there's the expense. Coloring at home was not attractive, as I'm not very coordinated when it comes to arts and crafts. I could only imagine that I'd do it all very unevenly. "If only there was something easy, like Sun-In," I thought. Back in the early 1990's, I used Sun-In during my college years. I was a lifeguard in summer, and I loved having my hair look lighter. I continued through the school year with Sun-In and a hair dryer, and my dark brown hair turned into a nice caramel. I loved it. Well, what do you know? Sun-In still exists! I read a little bit about it, and bought a bottle. After just 2 treatments with the hair dryer, the hair on top of my hair is lighter and the grays much less visible....even under those fluorescent lights. So I'm going to continue with once a week treatments to achieve a very subtle, but meaningful, change. I don't think the grays are gone, but they aren't showing up against the lighter hair as they did against my dark hair. It really is a remarkable difference. I know that won't work forever. But perhaps by the time I'm all gray, I will have become that enlightened woman who doesn't care and embraces her age. A girl can hope!!

I absolutely love this product! I use it to lighten my natural ashy brown hair. My hair is now a lightish brown and I love the natural highlight in my hair. I have noticed no damage to my hair. But I don't use it everyday. If I did I'm positive I'd eventually become platinum blonde. I haven't dyed my hair in years and started using it on virgin hair. I eventually became bored with my hair and wanted to lighten/change the color of my hair with little to no damage. (it took me too long to get long and healthy hair to just mess it, I've grown too attached to it quite frankly) My hair is wavy and the best time to put it in ur hairs is when you hair is still damp from the shower. To evenly distribute the product in your hair, while still damp (towel dry) spray as much or little as you want and then brush it through your hair while still damp/wet. Then after your hair is brushed either blow dry or lay out in the sun. For me, to get extra results after I blow dried my hair, I spray more in areas that I want lighten or all over (just light sprits) then I use a hair straightener. It leaves my hair extra shiny and smooth as well as lightens faster than just blow drying by itself. Though I don't do this very often because I know that heat from blow drying or straightening your hair is damaging, so when I do I put coconut oil serum in conjunction to using Sun In in my hair to help protect it from damage. The great thing is though is the coconut oil serum didn't interfere with the Sun In lightening effects.
