The Science Behind Hair Growth: Understanding the 4 Key Stages

Ever noticed more hair falling during stressful times? You’re not imagining it.Emotional and physical stress can directly impact your scalp, triggering excessive shedding or delayed regrowth — a condition known as telogen effluvium. ⸻ 1. How Stress Affects the Hair Cycle Under stress, your body releases cortisol, a hormone that disrupts the normal hair growth phases.This can push many follicles into the resting (telogen) stage too early, causing noticeable thinning weeks or months later. ⸻ 2. The Reversible Nature of Stress Hair Loss The good news: this type of shedding is usually temporary.Once stress levels balance, hair follicles often resume normal activity — but giving them an extra boost can accelerate recovery. ⸻ 3. Supporting Recovery Through Scalp Stimulation Incorporating red light therapy into your self-care routine helps reactivate stressed follicles by increasing scalp circulation and energy production at the root.It’s a calming, restorative process — one that mirrors inner healing.

Red light therapy isn’t just a beauty trend, it’s a scientifically proven innovation in scalp health and follicle rejuvenation.Known as Low-Level Laser Therapy (LLLT), it’s trusted by dermatologists and clinicians worldwide to stimulate hair growth naturally and safely. 1. The Science Behind Red Light Therapy Red light therapy works by emitting low-level wavelengths of 660nm (red light) and 850nm (near-infrared light).These wavelengths penetrate deep into the scalp, reaching the hair follicle cells and energizing them through a process called photobiomodulation enhancing ATP (cellular energy) production. The result? Stronger follicles, thicker strands, and visibly improved hair density. 2. Improving Blood Flow and Oxygen Supply Healthy hair starts with a nourished scalp.Red light therapy increases microcirculation, ensuring follicles receive more oxygen and nutrients vital elements for continuous growth and repair. 3. Reducing Inflammation and Follicle Stress Inflammation is one of the silent culprits behind hair loss. Red light helps reduce oxidative stress and scalp inflammation, creating the perfect environment for dormant follicles to awaken. 4. Consistency Is Key With just 30 minutes a day, the Jozouri HairGrowPro Cap makes this clinical-grade therapy effortless.Over time, users report reduced shedding, stronger strands, and revived confidence, all from home.

If you’re experiencing hair loss, you’re not alone. Many people face this common concern, but you can take action. Understanding the root cause of the condition may be the first step towards regaining hair confidence, but a supercharged beauty-tech treatment might just be the solution enter red light therapy for hair loss. What causes hair loss in men and women Genetics Genes determine your sensitivity to a hormone called dihydrotestosterone (DHT), the leading cause of hair loss in both men and women. Known as androgenic alopecia, or male or female pattern baldness, it causes follicles to shrink and hair to become finer and shorter with each growth cycle. Hormonal changes Hormones influence the body’s sensitivity to DHT. For women, pregnancy and menopause can cause hormones to fall out of balance, while thyroid issues can disrupt the hormones that regulate the hair growth cycle. Diet and nutrition As follicles need fueling with a steady supply of nutrients to function properly, nutritional deficiencies can cause hair shedding. A calorie-restricted diet can also lead to hair loss as energy is diverted away from the scalp to prioritise essential bodily functions. Lifestyle factors Sleep quality, stress and illness all influence the body’s ability to properly nourish hair follicles. While restorative sleep puts the body into a state of repair, producing hormones essential for hair growth, a lack of sleep is known to increase cortisol levels, disrupting the growth cycle, added to by stress and anxiety. Hair care habits Use of bleach, hair dye and heat styling tools can all lead to hair breakage and the appearance of thinning. Tight hairstyles and accessories can also damage follicles over time, causing hair loss known as traction alopecia.   How red light therapy can help hair loss   Red light therapy is a safe and non-invasive treatment that targets hair loss at a cellular level, boosting hair growth and density by: Energising cells Red light wavelengths increase the production of ATP (the energy currency of cells). This extra energy helps cells to function more efficiently, boosting growth and reactivating follicles in the resting phase. Extending the hair growth cycle This added cell energy also helps to keep hair follicles in the growth phase for longer, preventing the follicle from entering the resting and shedding phases. Reducing inflammation Red light therapy calms the body’s inflammatory response, soothing scalp conditions and creating a healthier environment for growth. Boosting circulation The energy from red light therapy improves blood flow, supplying follicles with oxygen and essential nutrients and removing toxins. This supports overall scalp health and provides follicles with the building blocks needed for healthy growth. A science-backed at-home solution, the CurrentBody Skin LED Hair Growth Helmet uses a spectrum of red light (620-660nm) to improve scalp condition and hair quality, for a calmer, healthier scalp and thicker, stronger hair.  When to see a specialist if your hair is falling out If you notice sudden, severe, or patchy hair loss, it’s best to consult a healthcare professional for advice. Helping to determine and address any underlying causes or alleviate strand-related stress, specialist advice can be an important step in your regrowth journey.
