Review: Easy, cheap way for my dark brown hair to lighten up. - 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.
Review: Love this! - 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.

### ⭐⭐⭐⭐ Great for subtly lightening hair - just don’t go overboard
*by C***S on May 8, 2025*

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.
