When you have low-density or low-porosity hair, you need to use something gentle that won't strip your hair too much. Both Shampoo A and Shampoo B would be great options, but you can also purchase a gentle shampoo so long as it is Blacklist-free and the pH is balanced between 4.5-5.5. Additionally, we recommend choosing lighter oils in your products that are suitable for low-porosity hair, like Squalane. You may even want to substitute with humectants, such as Aloe Vera Gel or Okra Gel, since these provide a lot of moisture without weighing your hair down.
