Surprisingly, the crosslinking baths themselves gelled, the cause of which was traced to a small amount of water present in the solvent [19]. Systematic studies of materials based on this chemistry followed shortly thereafter [20,58], resulting in the development of rationally designed polyurea aerogels derived from the reaction of isocyanates with water. Aerogel has been widely used in tissue engineering for the regeneration of different types of tissues, such as bones, skin, blood vessels, and cartilages.
Applications of Aerogels
However, severely damaged hair may require a trim to remove the damaged ends. High porosity hair will make your ends look very frayed and damaged. Another way to determine your porosity level is to look at the ends of your hair. Check out our article on everything you need to know about hair porosity to learn more.
Aerogels for Biomedical, Energy and Sensing Applications
Aerogels have the advantages of biodegradability and low density that make them a good choice for solving serious environmental problems. Researchers have proposed and developed many techniques that produce green and sustainable electrodes, based on aerogels, as a solution for pollution and other environmental concerns [73,74,75]. In an experimental study, Strobach et al. reported the synthesis of optically transparent and thermally insulating monolithic silica aerogels with high solar transparency, especially developed for the solar thermal receiver. They elaborated the effects of annealing at different annealing temperatures. They explained that the structures and properties of aerogels could be controlled by controlling the temperature. In addition, the time and temperature of annealing were helpful in the optimization of aerogels for better optical and thermal properties.

FAQs about High Porosity Hair
Both heat damage (from excessive use of hot styling tools) and mechanical damage (from vigorous brushing or wearing tight styles) can also cause high-porosity hair. Li et al. introduced a modified evacuated receiver with solar transparent aerogels in order to improve the receiver performance. In addition, they developed and validated an optical-thermal model for modeling the energy transfer in the collector. Figure 5 exhibits the traditional evacuated receiver that was chosen as a standard model and the modified receiver that was designed with the addition of aerogels at an angle of 120° at a directly illuminated region. The results revealed that the effects of aerogels on the modified receiver are significant. Aerogels coating’s emittance greatly affects the receiver performance.
Modern analytical techniques allow detailed characterization of materials and structure–property correlation from the molecular to macroscopic through the nano-scale regimes, in a continuous and often overlapping fashion. The gelation process itself is followed by multinuclear liquid-phase NMR, with light, X-ray, and neutron scattering, as well as rheology. Relevant to the nanoscopic structure of aerogels is the particle size and assembly, as well as the pore volume and structure. The usual methods to probe the solid framework include SEM, TEM, as well as X-ray, and neutron-scattering techniques. The pore volume and structure are evaluated from the micro- to meso- to macro pore size regimes via gas sorption methods (typically N2 at 77 K and CO2 at 0 °C). A non-distractive “look” inside macroscopic aerogel monoliths is usually achieved via X-ray tomography.
Don’t shampoo too often
Use a generous amount of deep conditioner, leave it in, and if possible, try to keep it warm using heat. To understand what hair porosity is, you need to understand a little bit about how your hair is made. Sign up to our newsletter and get exclusive hair care tips and tricks from the experts at All Things Hair. Many factors can play into this (such as the type of protein treatment used), so it is always a good idea to start slowly and pay attention to how your hair responds.
I’m just a girl who transformed her severely damaged hair into healthy hair. I adore the simplicity of a simple hair care routine, the richness of diverse textures, and the joy of sharing my journey from the comfort of my space. Notably, high porosity hair may not always necessitate protein treatments unless it has been previously damaged by the aforementioned factors. They can tell by the condition of your hair and how it reacts to products and treatments. The cause could be anything from over-processing with chemical treatments to damage from heat styling. When caring for high-porosity hair, make sure the scalp and hair are free from product buildup.

Unfortunately, those with high porosity hair often have to deal with knots and tangles. You’re lucky if you have naturally smooth hair because you don’t usually have to deal with tangles. On the other hand, having straight hair doesn’t necessarily mean that your shingles are flat or that you can’t have high-porosity hair. It might cost more, but having the chemicals applied by a trained professional makes a big difference for the safety of your hair.
Apple cider vinegar is another beneficial ingredient for highly porous hair. The acidity of the vinegar can help seal the hair cuticle to trap moisture. Medium (Normal) Porosity – the hair cuticles are raised enough to readily absorb moisture, oils, and chemicals. Normal porosity hair tends to hold moisture, shine, and absorb color and chemicals better than low or high-porosity strands. Protein treatments can help repair the hair cuticle and reduce hair porosity. Using a protein treatment can help fill in the areas in your cuticle that have damaged cells.
You know that just-got-out-of-bed look even if you’ve already washed and conditioned your hair? If you find yourself constantly reapplying moisturizer and conditioner to soften your hair, then that is a good indicator that you have high porosity hair. Fluid easily gets absorbed when you put a sponge on a surface with water. That absorbing ability is called “porosity.” It’s how water or other fluids can easily pass through small holes and get into an object. In this article, we’ll help you determine what porosity is, how to know if you have high porosity hair, and how to care for it properly. This doesn’t mean you have to stop styling your hair, just be more patient with a bit lower heat.
Co-owner, Nikki Lee, has several celebrity clients, such as Heidi Klum, Christina Applegate, Nelly Furtado, and Jewel. Sherry explains that glosses are a great way to add shine to your natural hair color, refresh old hair color, or blend out any grays. If you’re someone who struggles with frizz or dry hair, this treatment conditions, softens, and adds vibrancy to your locks.
