The ability of molecules to penetrate the hair shaft depends on various factors, including their size and structure, the condition of the hair, and the presence of any barriers on the hair surface. In general, smaller molecules have a better chance of penetrating the hair shaft, compared to larger ones.
The average diameter of a human hair strand is about 75 micrometers (0.075 millimeters). The cuticle layer, which is the outermost protective layer of the hair, consists of overlapping scales with gaps between them ranging from 1 to 30 nanometers (nm).
For molecules to penetrate the cuticle layer, they typically need to be smaller than these gaps, which are on the scale of a few nanometers. Molecules with a molecular weight below 500 Daltons (Da) are generally considered favorable for hair penetration. This range includes substances such as small organic molecules, vitamins, amino acids, and certain cosmetic ingredients.
In terms of size, molecules with a diameter of less than 1-3 nm have a better chance of passing through the gaps between the cuticle scales and penetrating the hair shaft. Here are some examples of molecules and their sizes:
These molecules fall within the size range, that allows them to potentially penetrate the hair shaft.
However, it’s important to note, that not all molecules can easily penetrate the hair shaft. The cuticle layer acts as a barrier, and the hair’s hydrophobic nature can further limit penetration. Researchers have developed various techniques, such as specialized delivery systems and conditioning agents, to enhance molecule penetration.
Ultimately, while smaller molecules generally have a better chance of penetrating the hair shaft, the ability to penetrate depends on multiple factors, including molecular weight, size, hair condition, and the presence of other barriers.
Water is the only substance on earth that naturally occurs in three physical states: liquid, solid, and gas. Depending on temperature and atmospheric pressure, water can change from one state to another, a process called physical phase change.
The 3 phases of water changes are, Liquid is water, solid is ice and gas is vapor.
And maybe there is more to water? Who knows, only the future, and science will tell.
Water is, by nature, most often structured. In the free flow of water in nature, the water twists and turns, creating a natural vortex. A drop of water contains trillions of water molecules held together by weak hydrogen bonds.
The tendency of water molecules to bond is called cohesion. The fact that water molecules cohere using weak hydrogen bonds, is what gives water its fluid consistency. Water’s polarity also makes it adhesive, which means that it will be attracted to other types of molecules with positive and negative charges.
Cohesion and adhesion are some of water’s most remarkable qualities. They are strong enough to work against the force of gravity, allowing water to move to the top of a tree hundreds of feet high. Motion, air, and vortex is an absolutely essentials for the structural quality of water.
When looking at water molecules photographed by Dr. Masaru Emoto, the molecules from a stream of untouched nature water have a high concentration of harmonic hexagonal water molecules, which indicates structured or clustered water with a higher energy level.
This natural structured water is more energy-filled, and adds more energy to living organisms, plants, and minerals. Unstructured water on the other hand, has less energy.
Nearly 70% of the mass of the human body is water.
