Blondes and sandy brunettes know that water and swimming can be hazardous to your hair. Anybody who swims a lot can suffer from green hair syndrome, though, not just those with light hair. If you want to prevent green hair, all you have to do is simply never expose it to air, sunlight, water or chemicals.

Since that's not possible, this guide will show you some ways to prevent and remove green hair if yours happens to get tinted from sunlight and swimming.

If you're not going to be washing your hair, you can wear a swim cap when showering to protect your hair from exposure to the water and the chlorine that's in your municipal water supply. If you're swimming, wearing a swim cap will also protect your hair from the additional chlorine and chemicals used in a swimming pool that are notorious for turning hair green. A swim cap will keep water from getting to your hair and prevent the chemicals from altering the hair and causing the green color.

So you went swimming without the swim cap in step one. Yes, swim caps aren't the most attractive and it's not like you're a professional swimmer, right? So now you have lightly tinted green hair. What to do?

Wash with tomato juice. It can be straight tomato juice from a can or a jar, real tomato juice you make yourself or tomato paste. The canned tomato juice seems to work the best, but you can even use V8 Juice if you'd like.

The tomato will strip the green from your hair safely and naturally and leave your hair feeling soft and luxurious.

If tomatoes aren't your thing or you are allergic to them, there are some other home remedies to try on your hair to remove the green. These remedies are often recommended by beauty and salon professionals for blondes seeking an inexpensive and non-chemical way to prevent green hair.

Baking Soda Paste

Take some baking soda and add a little water until you have a glue paste. Using your fingers, smooth the paste along the strands of your hair until coated and let is sit on the hair for a few minutes. Rinse away completely with warm water, making sure to let the water run clear.

Lemon Juice Wash

Lemon juice can help strip oils and the green tint from your hair. If your hair's been dulled by chemicals, lemon juice will make it look fresh and vibrant again. You don't want to use it too frequently, though, so if you're a regular swimmer, try to use the other options and save lemon juice as a last resort to remove or prevent green hair.

Vinegar Wash

Just like the lemon juice, you can wash your hair with vinegar and rinse it through to help remove buildup and prevent green hair after swimming.

Salons will suggest that you buy a clarifying shampoo that contains EDTA (Ethylene Diamine Tetra Acetic Acid). If you swim regularly, use the EDTA shampoo immediately after getting out of the pool, so the chemical removes the chlorine green effect before it settles in. These shampoos can be used regularly for those with light hair who get green hair just from the normal shower or bath.

If all other steps fail, you can always go to a salon and ask them how to deal with your particular hair problems and green tinting.
