Infrared is a light wavelength that penetrates deeper into the hair shaft, heating the hair evenly and safely from the inside out. It’s designed to steam the hair instead of applying a direct heat. This allows you to use less heat, and by minimizing the exposure to heat, you alleviate styling stress on the cuticle. Hair’s overall appearance is improved, and it looks shinier.

This is helpful because hot tools can be harsh on the outer layer of hair, lifting up the cuticle, which dries out strands, and can leave hair looking damaged. Once that happens, it’s harder to maintain your given style because water from the air in the form of humidity will enter the hair shaft and puff it up, making it look frizzy.


Conventional styling tools provide infrared waves in the Near and Middle segments. These infrared rays have wavelengths that are not sufficient to penetrate hair or the scalp for healthy styling. Because of non-penetration, these shorter infrared rays heat the air surrounding the hair and conduct the hot air to the surface of the hair. The hair is heated by means of conduction from the surface which causes frizzy, dry and damaged hair.

SA’s styling tools use the longer wavelength from Far Infrared technology to generate deep penetrating heat. This penetrates directly into the cortex of hair cuticles, heating from the inside out. It creates an effect that relaxes and softens hair. The hair is heated evenly, giving a gentle drying process in half the time thereby reducing heat exposure. Water molecules on the surface of the hair break apart into smaller droplets and get absorbed into the hair. Moisture is then locked within the cuticles to give a protective barrier to reduce chemical and bacteria build-up.

Conventional irons leave the cuticles dry and frizzy. Small blood vessels in the scalp supply cells with essential nutrients and oxygen and carry away waste products. When the scalp lacks a supply of nutrients and oxygen, toxins build up that can lead to unhealthy hair, dry scalp and reduced follicles. Some of these toxins include carcinogenic heavy metals and poisons from food processing, lactic acid, free fatty acids, uric acids and subcutaneous fat associated with aging and fatigue.

Toxins are encapsulated by water and blood that are trapped throughout the body, including the scalp. Where the toxins have accumulated, blood circulation is blocked and cellular energy is impaired. However, when Far Infrared penetrates the scalp, they stimulate micro vibrations that cause a thermal reaction that elevates tissue temperatures. The energy from Far Infrared vibrates the water molecules and reduces the ionic bond between water/blood and toxins. As water breaks down, the encapsulated toxins are released. Because of the thermal energy, the scalp reacts by dilating all the blood vessels providing improved circulation to carry the toxins away. Improved circulation delivers nutrients and oxygen rich blood cells to revitalize tissues therefore leading to rejuvenated scalp to reduce dandruff, maintain healthy follicles to prevent hair loss, and healthy hair.

Why Far Infrared Has These Benefits

All molecules vibrate at a certain frequency. Cells in our body absorb the most energy when the heat source has the same intrinsic vibration frequency as the cells themselves. Only Far Infrared has a specific frequency with 8-14 microns wavelength that allows it to penetrate the skin and energize the cells. This range, sometimes called “Vital Rays”, has special regenerative effects on the body.

Is Far Infrared Safe?

Far Infrared is safe and healthy for the human body. Any excessive exposure passes through the cell without any adverse effects. One can be exposed to Far Infrared heat for hours and it will not cause burns to the skin. In fact, hospitals use it to warm newborn infants.

In summary, Sa’s Far Infrared hair dryers and flat irons can not only dry the hair faster, but also activate vital functions to maintain healthy hair and scalp. The use of Far Infrared’s penetrating rays reduce frizz, make the hair soft, shiny and retain moisture.
