How do you make shampoo made of kalamansi?

To make kalamansi shampoo, start by extracting the juice from fresh kalamansi fruits. Combine the juice with a gentle, natural base shampoo, mixing in a ratio of about one part kalamansi juice to three parts shampoo. Optionally, you can add a few drops of essential oils for fragrance and additional benefits. Finally, store the mixture in a clean bottle and shake well before each use.
