Do Red Light Helmets Actually Work for Thinning Hair?

What red light therapy can (and can't) do if you're dealing with hair loss, thinning, shedding or androgenic alopecia.

This post contains a paid partnership with CurrentBody.

Easy to use: hands-free, whole head coverage and comes in two sizes for a comfortable and effective fit.

If you’re dealing with hair loss, you’ll know this already: it’s exhausting. Not just emotionally, but practically. The promises, the claims, the before-and-afters that feel wildly optimistic, all of it can make you want to opt out entirely.

So, when devices like the CurrentBody Hair Helmet cross my desk, my instinct isn’t excitement, it’s caution. And then curiosity.

Because, while haircare has become more sophisticated in recent years, more science-led, more scalp-focused, it’s also become noisier. And, if you’re living with androgenic alopecia, as I am, or have any kind of hair loss, thinning or shedding issues, then you don’t have the luxury of buying into the hype. You need things that support progress, not distract from it.

I’ve been using the CurrentBody Hair Helmet consistently - 10 mins a day, usually at my desk while I power through my inbox.

What the Science Says…

So what does this CurrentBody Hair Helmet do and how does it work? Red and near-red light therapy isn’t new, nor is it fringe. In clinical and trichology settings, specific wavelengths of light have been used to support hair growth by improving the environment in which follicles operate.

The CurrentBody Hair Helmet uses two targeted light ranges:

• 650-660nm red light, which has been shown to help reactivate dormant follicles by stimulating cellular activity at the follicle level.

• 620-630nm light, which focuses on calming the scalp, reducing inflammation and supporting overall scalp health.

Combined, these wavelengths aim to do the three things that matter when you’re dealing with hair loss issues:

1. Wake up follicles that have slipped in dormancy.

2. Improve circulation so follicles receive more oxygen and nutrients.

3. Create a calmer, less inflammatory environment for growth to resume.

The clinical data is solid rather than sensational. In trials over 12 weeks, results showed:

• 72% reduction in hair loss

• 123% faster hair growth

• 26% increase in hair thickness

None of this suggests miracles. It’s not an overnight transformation, it’s steady improvement and, with hair, that’s exactly what you want.

This is the kind of change LED therapy aims for: improved density through follicle support. Progress here is incremental, subtle, and meaningful if hair loss is something you’re managing long term.

Where this fits if you’re already treating hair loss.

If you’re already using a topical scalp treatment, whether it’s minoxidil (as I am) or another growth-supporting product, this is where the helmet tends to fit in nicely. It’s not about helping products ‘sink in’ more, but about creating better conditions for them to do their job. Improved circulation, a calmer scalp and healthier follicles all make a difference, which is why LED therapy is often used alongside topical treatments in clinics rather than as a replacement. It’s very much a team effort rather than an either/or.

If you’re using both, timing matters:

• Apply topical treatments separately from LED sessions.

• Allow products to fully absorb before using the helmet, or use the helmet at a different time of day.

What’s noticeable hair is reduced scalp visibility as dormant follicle are encouraged back into activity. This is how improvements often shows up at the start.

My personal reality check.

For me, recovery from androgenic alopecia didn’t start with a device. It started when I finally sought proper help and began a treatment plan that included topical minoxidil. That was the foundation.

What appeals to me about LED therapy, and this helmet in particular, is that it’s FDA-cleaned, non-invasive, pain free, drug free and incredibly easy to use. There’s no systemic impact, no hormonal involvement, and no irritation masquerading as ‘activation’.

It’s also something you use consistently and quietly, without drama. The full-coverage, hands-free designs is important here because being able to be consistent is so vitally important when embarking on any treatment. And, when it comes to hair, it’s this kind of consistency that tends to outperform everything else

LED therapy doesn’t force growth where follicles are no longer viable, but it does support the ones that still are. Thicker in appearance, better coverage and improved hair quality are often the earliest wins..

The Bottom Line.

The CurrentBody Hair Helmet isn’t a replacement for medical treatment, nor is it a cosmetic gimmick. It sits in the incredibly important middle ground: evidence-backed support that helps existing treatments work better while supporting scalp health and follicle function.

For anyone navigating hair loss, that middle ground is where most meaningful progress now lives. And that, in itself, feels like progress.

If you’re considering LED therapy as part of your hair loss strategy, the CurrentBody Hair Helmet is one of the more credible options I’ve seen - particularly when used consistently and alongside established treatments.

If you do decide to try it, there’s an exclusive 10% discount code available using the code EMMAGUNS, which makes experimenting feel a little less daunting. As ever, consistency matters more than anything else.
