What is the potential for the sun to change hair color?

I was thinking about naturally lightening my hair color with the sun. Do you know how long it will take? Right now my hair is medium-brown, i'd like to make it just brown. Is it possible? What potential does the sun have for lightening hair color?What is the potential for the sun to change hair color?
I have two answers for your initial question. You can lighten your hair via Sun-In, a powerful hair lighteninig product that is tricky, but delivers, or saturate it with lemon juice and sit out in the sun.





Option #1:


Sun-In typically has a bad name, because it is tricky to use, and occasionally gives bad results. It comes in a spray bottle, and it is about 5 dollars at most stores. It has a natural look, is long lasting, has a great color, and is versatile. You can easily add more at the roots for touch ups to maintain your desired color. Sun-In also works fairly fast.





A common misinterpretation is that Sun-In will make your hair ginger. This is not true, unless you use it incorrectly and go swimming while it is in your hair. This is also damaging for your hair, so don't do it!





How It Works:


When you use Sun-In, heat is what lightens your hair. Naturally, this would only be available when it is hot and sunny, but you don't even have to go outside to get its effects. You can spray it through your hair and use a blowdryer's heat to undergo the process. Its effects are almost immediate, so you don't want to put too much at first.





Here are some facts from the website I listed below:


- Sun-In uses a low volume hydrogen peroxide


- Most hair colors and all lighteners use hydrogen peroxide, and most blonde shades use a much higher volume than Sun-In, therefore Sun-In is NOT going to ';fry'; your hair any more than traditional color


- The difference is that Sun-In lightens your hair without depositing a color into it as it lightens, so natural ';warm'; pigments show through. So depending on how much natural ';warm'; pigments are in your hair will determine the results you'll get


- Using a blow dryer on high heat will yield much more even and less brassy results








Option #2:


To have more control over the lightening process, I recommend using lemon juice. Lemon juice is acidic, and isn't the best for your hair if used frequently, so I recommend deep conditioning before you start the process. After washing your hair, wring out excess water with a towel. Get a squirtbottle and fill it with lemon juice and a little bit of water, to have extra control over how light your hair gets. Spray it evenly through your hair for an all around lightened color, or select sections for a streaked look. Put on a good sunscreen and sit out in the sun for an hour or so. This will get boring, so you can go jogging or do other activities. Bring a waterbottle to stay hydrated, and make sure your hair gets enough sun!





Good Luck!
