A High-Porosity Routine. To replenish moisture loss and repair the damage often present in high-porosity types, professionals say using a richly hydrating leave-in treatment each day is a must.
Hair porosity refers to how your hair handles hydration and you can have high porosity hair or low porosity hair. This test will help you figure out which type you are and what products to use.
Scalp hair was reported to grow between 0.6 cm and 3.36 cm per month. The growth rate of scalp hair somewhat depends on age (hair tends to grow more slowly with age), sex, and ethnicity. [3] Thicker hair (>60 μm) grows generally faster (11.4 mm per month) than thinner (20–30 μm) hair (7.6 mm per month). [4]
Connected porosity is more easily measured through the volume of gas or liquid that can flow into the rock, whereas fluids cannot access unconnected pores. Porosity is the ratio of pore volume to its total volume. Porosity is controlled by: rock type, pore distribution, cementation, diagenetic history and composition. Porosity is not controlled ...
This porosity can range in size, from sub-micron to voids greater than 10 mm, depending on the casting. Casting defects caused by porosity can affect the part’s structural integrity, creating a failure point. Porosity can also prevent the part from being pressure tight. This will impact performance if the part is designed to hold gases or ...
The original hair type chart, also known as the hair typing system, was created by Andre Walker, Oprah Winfrey's hairstylist, in the 1990s. He debuted the system on Winfrey's show to promote his ...
