Do you ever wonder why a product works for you but not for your daughter? You ask questions like “but we have same hair texture, why is her hair always dry?” It might be that you have different hair porosity.
Hair porosity is how well your hair is able to absorb and hold moisture. How the cuticle (the flexible outer layer of your hair) determines how easily moisture and oils pass in and out of your hair. Knowing this will help you tailor the right products to use in your hair.
How do you check the porosity of your hair?
There are two methods:
Float Test: Take a some strands of ‘freshly washed’ hair from a comb or brush and drop them into a glass of lukewarm water. Set your timer for 4 minutes and wait. Your hair will float if it has low porosity and would sink if it has high porosity.
The Slip’n’Slide Test: Take a strand of hair and slide your fingers up the shaft (toward the scalp). If you feel little bumps along the way, this means that your cuticle is lifted or damaged and you have high porosity. You have low porosity hair if your fingers slip smoothly upwards.
In my next post, I will talk about the products to use for each type of porous hair.
