Shampoos for Curly Hair

General Recipe:

1. Primary Surfactants (10-15%): Mild surfactants such as Sodium Cocoyl Isethionate or Cocamidopropyl Betaine. These cleanse the hair and scalp without stripping too much natural oil which is crucial for curly hair.

2. Secondary Surfactants (2-7%): Secondary surfactants like Sodium Lauroyl Sarcosinate or Sodium Methyl Cocoyl Taurate can help to boost the cleansing power and increase lather.

3. Conditioning Agents (2-7%): These help to hydrate and soften curly hair, which tends to be drier than straight hair. Ingredients can include Cetyl Alcohol, Stearyl Alcohol, or Behentrimonium Methosulfate.

4. Humectants (3-8%): These are ingredients like Glycerin or Propylene Glycol that can help to attract and retain moisture in the hair.

5. Proteins (1-5%): Ingredients like Hydrolyzed Wheat Protein or Hydrolyzed Silk can help to strengthen the hair and add shine.

6. Thickening Agents (0.5-2%): Agents such as Xanthan Gum or Hydroxyethylcellulose can be used to adjust the viscosity of the shampoo.

7. pH Adjusters (0.1-1%): These can be used to balance the pH of the shampoo. Citric Acid is a common choice.

8. Preservatives (0.5-1.5%): Ingredients such as Phenoxyethanol or Sodium Benzoate are used to prevent microbial growth in the shampoo.

9. Water (to 100%): The remaining percentage of the formula is water, used as a solvent.

Additional ingredients like fragrance, colorants, or botanical extracts can also be added to customize the product. These shampoos are designed to enhance curls and reduce frizz, often more moisturizing than other types.
