Noticing more hair fall than usual? Or feeling like your strands are thinning out faster than they used to? You’re not alone, and more importantly, you’re not without options.
Red light therapy is quickly becoming a go-to for people who want thicker, fuller, healthier hair. It’s gentle, non-invasive, and yes, it actually works by using the power of light.
Backed by clinical research (even NASA studied it), red light therapy is safe to use at home and designed to support your scalp from the root. Whether you’re just starting to notice changes or dealing with ongoing hair concerns, this could be the support your scalp has been needing.

What Is Red Light Therapy?
Red light therapy (also known as low-level laser therapy) uses specific wavelengths of red and near-infrared light - usually between 630 and 850 nanometres — to support your body’s natural healing processes, especially at the scalp.
It was first used to help with wound healing and skin repair. These days, it’s commonly used to improve scalp health and support hair growth.
At Curerest, we use 850nm red light, which goes deeper into the scalp to energise your follicles and help kickstart growth right where it matters most.
How Red Light Therapy Supports Hair Growth
Hair grows in phases:
-
Anagen (growth)
-
Catagen (transition)
-
Telogen (rest/shedding)
But stress, hormones, inflammation, or even buildup on the scalp can disrupt this natural cycle, causing strands to thin, shed prematurely, or stop growing altogether.
Red light therapy helps bring that cycle back into balance by working deep at the cellular level.
1. It Recharges Your Follicles
Red light energises your cells by boosting ATP — your cells’ natural energy source. Think of it like recharging your hair follicles’ batteries. When your scalp cells have more energy, they stay active longer and produce stronger, healthier hair.
2. It Increases Blood Flow and Nutrient Delivery
Red light gently increases circulation in the scalp. This helps deliver more oxygen and nutrients to each follicle — giving your roots what they need to grow and thrive.
3. It Calms Scalp Inflammation
Ongoing scalp inflammation is a hidden trigger for hair thinning. Red light helps soothe irritation, reduce redness, and create a healthier environment where new growth is more likely to happen.
4. It Wakes Up “Sleeping” Follicles
Hair growth can slow down or stop altogether in some areas. Red light helps encourage dormant follicles back into the growth phase (anagen), especially in early-stage hair loss or thinning.
Why It’s So Popular (Especially Right Now)
Between work stress, hormonal shifts, postpartum recovery, and lifestyle factors — it’s no surprise more people in their 20s and 30s are noticing changes in their hair.
Here’s why red light therapy is quickly becoming a go-to solution:
✅ It’s natural – no harsh chemicals
✅ It’s safe – gentle on the scalp and skin
✅ It’s non-invasive – no pills, no needles, no downtime
✅ It’s proven – backed by decades of clinical research
✅ It’s easy – fits into your weekly self-care routine at home
It’s Especially Helpful If You’re Experiencing:
-
Early-stage hair thinning
-
Postpartum or hormonal changes
-
Slowed or stunted hair growth
-
Shedding triggered by stress or inflammation
What Does the Research Say?
Red light therapy isn’t a passing trend — it’s been studied for decades, including by NASA, who used it to support healing in space. That research helped spark deeper studies into how red light helps our cells here on Earth — including the ones responsible for hair growth.
📚 A Few Key Studies:
-
A 2017 study found that men and women using red light therapy experienced noticeable improvements in hair density, thickness, and scalp coverage after just 16 weeks.
-
A 2014 trial showed significantly more hair regrowth in participants using red light helmets compared to those who received a placebo.
-
The Australasian College of Dermatologists supports red light therapy as a valid treatment for pattern hair loss (androgenetic alopecia).
Long story short: the science is solid.

Are There Any Drawbacks?
Red light therapy is very safe, with little to no risk — but there are a few things to keep in mind:
⚠️ It’s not a quick fix – results take time and consistency
⚠️ It works best in early to moderate stages of hair thinning
⚠️ It’s not a standalone cure – for best results, pair it with a scalp-first routine
It’s also totally fine to use alongside other treatments like topical serums, medicated shampoos, or gentle exfoliators.
