If you have high-porosity hair that is experiencing frizz and dryness then you'll want to incorporate some moisture treatments and moisturizing ingredients into your routine. For example, oils, humectants and BTMS are all great moisturizers, though you'll want to be sure to use them in accordance with your Unique Hair Profile. Do keep in mind that humectants are best used when the dew point in your geographic region is between 5°-15°C/40°-60°F.
