Inadequate intake of essential nutrients, particularly: vitamins, such as:: biotin, vitamin D, and iron minerals and proteins, can impact hair health. Nutrition deficiency can weaken hair follicles, which leads to hair thinning and loss.
Hormonal imbalances
Hormonal fluctuations, such as: those experience during pregnancy, menopause, and thyroid disorders can contribute to hair loss. Hormones play a crucial role, in regulating the hair growth cycle, and any imbalances can disrupt the normal growth process.
Medical conditions or treatment
Certain medical conditions, like: alopecia areata, (autoimmune disease) scalp infections, and certain medications, such as: chemotherapy drugs, can trigger permanent or temporary hair loss.
Environmental factors.
Exposure to environmental pollutants, excessive heat styling, frequent use of harsh hair products, and tight hairstyling, that pull on the hair, can damage follicles and result in hair loss.
Types of hair loss

Male pattern baldness

Androgenetic alopecia is the most common form of hair loss In men, which is characterized by, receiving hairline and thinning hair on the crown. It is caused by, genetic factors and hormonal changes.
Female pattern hair loss

This is similar to male pattern baldness, female pattern hair loss involves gradual thinning of hair across the scalp, primarily, affecting the center part and the crown area. Hormonal imbalances, genetics, and aging contribute to this type of hair loss.
Alopecia arietta
Alopecia areata is an autoimmune condition, that causes patchy hair loss. It occurs, when the immune system mistakenly attacks hair follicles, resulting, in hair falling out, in small, round patches.

What is red light therapy?

Red light therapy, also known as:, low-level light therapy LLLT or photobiomodulation PBM, is a non-invasive treatment, that, involves the wavelength of red and near-infrared light, to stimulate cellular activities. These wavelengths penetrate the skin, reaching underlying tissues and interacting with cells to produce therapeutic effects. But, how does red light therapy work? Let’s, take a look.
How does red light therapy work?
Red light therapy works at the cellular level, which involves various biological processes in the body. Here is a breakdown of its mechanism for improving hair health.
1: Increased blood circulation

Red light therapy stimulates blood flow to the treated area, promoting the delivery of oxygen and nutrients to the hair follicles. This increases circulation, nourishes follicles, and supports their healthy functioning.
2: Stimulation of hair follicles
The red and near-infrared light wavelengths penetrate the scalp and reach the hair follicles, this light energy is absorbed, by, the follicles triggering a series of cellular reactions. It stimulates the mitochondria, which are the powerhouses of the cells, promoting ATP adenosine triphosphate production. 80p is crucial for cellular energy, which fuels hair growth processes. In other words, it’s actually, a long word for our cell energy.
3: Reduction of inflammation
Red light therapy has anti-inflammatory properties that, can help to reduce inflammation, in the scalp. Inflammation can contribute to hair loss by, disrupting hair follicle activities. By, reducing inflammation, red light therapy, creates a more favorable environment for hair growth.
