In today’s digital age, we are constantly exposed to screens and devices emitting blue light, also known as High Energy Visible (HEV) light. While the potential adverse effects of blue light on our eyes and sleep patterns are well-documented, the impact of HEV light on our hair and scalp is a topic that has gained less attention. Let’s explore the benefits of using a “Blue Light Shield” for hair and scalp protection and delve into the harmful effects of HEV light on our precious locks and scalp health.

Understanding Blue Light and HEV Light

what is blue light

Blue light is a component of the visible light spectrum with a short wavelength and high energy. It is emitted by natural sources like the sun, as well as artificial sources such as LED screens, smartphones, tablets, and fluorescent lighting. Blue light exposure has been linked to digital eye strain, disrupted sleep patterns, and potential long-term damage to our eyes.

High Energy Visible (HEV) light is a subset of blue light with wavelengths ranging from 380 to 500 nanometers. HEV light is notorious for its ability to penetrate deeper into the skin compared to other forms of light, and it can have detrimental effects on various aspects of our health, including our hair and scalp.

The Harmful Effects of HEV Light on Hair and Scalp

  1. Oxidative Stress and Hair Damage:

HEV light can lead to oxidative stress on the scalp and hair follicles. Oxidative stress occurs when there is an imbalance between the production of harmful free radicals and the body’s ability to neutralize them. This imbalance can cause cellular damage, and in the case of the scalp, it can affect the health of hair follicles.

  1. Premature Aging of Hair:

Exposure to HEV light has been linked to premature aging of the hair. The oxidative stress caused by HEV light can lead to the breakdown of proteins and essential lipids in the hair, resulting in dryness, brittleness, and a lackluster appearance. Over time, this can make hair look and feel older than it actually is.

  1. Hair Color Fading:

HEV light can also impact the vibrancy of hair color. It can lead to the fading of dyed or natural hair color by degrading the pigments responsible for hair coloration. This effect is particularly noticeable in individuals with vibrant or unnatural hair colors.

Some hair products feature both color protection and blue light shield for maximum color longevity. Click here for more information on JOC Color Protection Products with Blue Light Shield.

  1. Scalp Health:

The scalp is the foundation of healthy hair growth, and its well-being is closely linked to the health of your hair. HEV light can potentially harm the scalp by causing inflammation and increasing the production of sebum, leading to conditions like dandruff and oily scalp.

Given the potential harmful effects of HEV light on hair and scalp health, the concept of a “Blue Light Shield” has emerged as a protective measure. A Blue Light Shield, often found in specialized hair care products and treatments, is designed to mitigate the negative impact of HEV light. Here are the key benefits of using a Blue Light Shield for your hair and scalp:

  1. Protection from Oxidative Stress:

A Blue Light Shield forms a protective barrier against HEV light, preventing it from penetrating deep into the hair and scalp. This shield helps reduce the oxidative stress caused by HEV light exposure, preserving the health of your hair follicles and scalp.

  1. Retaining Hair Color:

For individuals with dyed hair or those who wish to maintain their natural hair color, a Blue Light Shield can help prevent color fading caused by HEV light. By blocking HEV light from reaching the hair shaft, the shield helps retain the vibrancy and longevity of your chosen hair color.

  1. Scalp Health Maintenance:

A healthy scalp is the foundation for healthy hair growth. A Blue Light Shield can contribute to scalp health by reducing inflammation and the risk of scalp conditions like dandruff and excess sebum production. A well-balanced scalp is essential for strong, resilient hair.

  1. Enhanced Hair Care Products:

Many hair care products now include Blue Light Shields as a key ingredient.

  2. Wear Protective Headgear: In situations where you anticipate prolonged exposure to HEV light, such as outdoor activities, consider wearing a hat or cap to shield your hair and scalp from direct sunlight and artificial light sources.
  3. Use Screen Filters: Apply screen filters or install blue light-filtering apps on your electronic devices to reduce the amount of HEV light emitted from screens.
