After a long, hot Summer, platinum blonde highlights often turn to dishwater blonde highlights. This hair treatment includes lemon extract to clarify and brighten, honey and wheat germ to nourish, and oil to moisturize dry hair.

For the recipe and instructions .

Here's what you need. (This will make plenty. If you have short hair, you can halve this recipe.)

1/2 cup olive oil
2 tablespoons honey
2 tablespoons lemon extract
Juice and pulp of half a lemon
2 tablespoons wheat germ

Mix all ingredients together well. Put the mixture in the sink and pull it through dirty hair, making sure to get the roots and ends. Pull hair back and wait 20 to 30 minutes. Take a hot shower, combing the mixture through your hair. Since this is a treatment and not a conditioner, you'll want to shampoo and condition to remove it all (especially the wheat germ).
