The human skin is more acidic than a dog’s; this means the pH is lower. The top layer of skin is known as the acidic mantle and is the one that causes the acidic nature.

For that reason, when manufacturers are making human shampoo and soaps, they design them with a low pH to protect and maintain the skin’s nature.

To avoid that, you can go for cheaper options like using an electrical nit comb as it works wonders. Apart from that, you can use baby oil to remove the lice.

Using a dog shampoo may seem like a wise decision and alternative, but it is not. You may end up causing more harm to your skin and expose it to diseases. Find another solution such as using a block of bar soap for the time being until you get your shampoo. Similarly, don’t use human shampoo on dogs as it will interfere with their skin and cause more issues; instead, use plain water.
