Answer:
If you have hair with poor porosity, you should choose a perming solution that is suitable for your hair type. Here are some options:
1. Acid Perming Solution: Acid perms are good for hair with poor porosity. They have a lower pH level, which means they are less harsh and can minimize damage to the hair. Acid perms provide a softer and more natural-looking curl or wave.
2. Low-alkaline Perming Solution: Low-alkaline perms have a pH level between acid and alkaline perms. They are a suitable choice for hair with poor porosity because they strike a balance between gentle processing and effective curling. Low-alkaline perms are often recommended for fine or fragile hair.
3. Moisturizing or Conditioning Perming Solution: Look for a perming solution that includes moisturizing or conditioning ingredients. These solutions can help add moisture to your hair and improve its overall condition. Moisturizing or conditioning perms can make your hair more receptive to the perming process and reduce the risk of damage.
Remember, it's always a good idea to consult with a professional hairstylist or trusted product manufacturer for specific recommendations based on your hair's needs and condition. They can provide personalized advice to ensure you select the most appropriate perming solution for your hair.
