How to Make Shampoo
To make your own shampoo, start by getting a bar of soap that's made with all natural ingredients. Then, use a cheese grater or knife to cut up the soap so you have 4 ounces of soap flakes. Next, bring a quart of water to a boil and pour it over the soap flakes, which will make them dissolve. Once all of the soap flakes have dissolved, add a 1/4 cup of almond oil and 8 drops of your favorite essential oils, like peppermint and lavender oil. Finally, let your shampoo cool before transferring it to a bottle.
Gather ingredients. This shampoo recipe can be made with any type of soap flakes. Castile soap flakes are commonly used in shampoo, but you can also make shampoo using flakes you create from a regular bar of soap.  Just make sure the soap is made with natural ingredients that you'd want to use in your hair. You will need: Soap flakes Boiling water Almond oil Essential oils Flake the soap. If you didn't buy pre-flaked soap, use a cheese grater or a knife to cut off small flakes that will dissolve in hot water. You need about 4 ounces of flakes to make a quart of shampoo. Place the flakes in a large bowl. Boil the water. Pour a quart of water into a small saucepan and bring it to a boil on the stove. Alternatively, heat a quart of water to boiling in the microwave. Pour the water over the flakes. The boiling water will immediately dissolve the small soap flakes. Use a spoon to stir the mixture to make sure the flakes dissolve completely. Add the oils. Pour in 1/4 cup almond oil and 8 drops of your favorite essential oil, like lemon balm or peppermint. Stir the mixture well and allow it to cool. Pour the shampoo into a bottle. Use a funnel or simply carefully pour the shampoo into an old shampoo bottle to store it for later use. Gather ingredients. Shampoo for dry hair has ingredients that provide extra moisture and prevent the hair from getting too frizzy. Dry hair is also susceptible to getting damaged and broken, so this shampoo is made to strengthen the hair shaft. Pick up these ingredients from a health food store: Chamomile tea Liquid castile soap Olive oil Tea tree essential oil Peppermint essential oil Rosemary essential oil Make the tea. Steep a chamomile tea bag in 2 oz. boiling water for 10 minutes. If you have loose chamomile flowers, use about 1 tablespoon. Strain the tea and set it aside to cool. Heat the castile soap. Pour 12 oz. of soap into the measuring cup. Heat the soap in the microwave in 1-minute increments until it is hot. Do not bring the soap to a boil. You can also heat the soap in a small pot on the stove; just make sure it doesn't get too hot. Add the oils. Stir in 1/2 oz. olive oil, 1/4 oz. tea tree oil, and 1/8 oz. each peppermint and rosemary oils. Stir the soap, gently after adding each oil. If bubbles form, spray the surface of the soap with rubbing alcohol. Mix in the tea. Add the chamomile tea to the hot soap. Pour it slowly to avoid creating bubbles. Set the shampoo aside to cool.

The shampoo will work will without these ingredients. A blender or coffee grinder will work in place of a food processor. Place the mixture in a spice shaker. Pour it into an empty, clean salt or pepper shaker, which you can use to shake the mixture over your head when you want to use it. Store the remainder of the shampoo in an airtight container so that you can use it when it's time to refill the spice shaker. Use the dry shampoo when your hair is completely dry. Otherwise, it will stick to your hair. Apply the shampoo to your roots, use a brush to distribute it throughout your hair, let it sit for 10 minutes, then brush it vigorously to remove the excess powder from your hair.
