Pour two inches of water in a cup (four inches if your hair is really thick or long). Plop two (or four, if you're doubling it) antacid tablets into the water and let it fizzle, until it's all dissolved.
Squeeze out two squirts of baby shampoo into the fizzing antacid. Use a spoon and stir things up really well, until it's all mixed.
Pour the antacid shampoo on your hair and work it in with your fingers. Sit back and relax for 10 minutes; let it sit on your hair.
Rinse it completely with warm water. Apply your regular shampoo and wash, then condition your hair as usual.
Pour a quarter to a half cup of regular, undiluted ketchup (the same one you use for burgers and fries) into a cup.
Step into your shower, wet your hair down and empty the ketchup over your hair. Make sure to massage it in with your fingers or comb it through with a comb, so that each strand is coated and spread to the ends.
Text a friend, watch a show on television or just take a nap. However, leave the ketchup in your hair for at least 20 minutes, before rinsing.
Shampoo and condition your hair as usual.
Lemon and Baking Soda
Mix 2 tablespoons of baking soda into a quarter cup of lemon juice. To that, add one teaspoon of baby shampoo or some other type of mild shampoo. Stir it up to completely to combine the ingredients.
Pour the mix over your hair and comb it through to the ends.
Put on a plastic cap (a shower cap will work just as well). Make sure you tuck all of your hair in, so that it is completely covered.
Wait for 30 minutes and then remove the cap. Go into the shower and rinse your hair out using warm water, to remove all of the mix. Shampoo and condition your hair as normal.
