Frequently Asked Questions
General Questions
Does light therapy actually work?
Yes, light therapy has solid scientific backing and is used in both skincare and hair treatment for its documented benefits. Red and near-infrared light stimulate the skin's natural regeneration processes, promote collagen production, and can reduce visible signs of ageing such as fine lines, wrinkles, and pigment spots. At the same time, blue light can effectively combat acne by reducing bacteria and sebum production.
Regarding hair care, research has shown that red light can stimulate hair follicles and improve blood circulation in the scalp, which can contribute to healthier hair growth and reduce hair loss.
It is important to remember that results may vary from person to person, and for the best effect, light therapy should be used regularly as part of a holistic skin or hair care routine.
Is light therapy completely safe?
Yes, our products are safe to use!
Light therapy is a gentle, painless, and non-invasive treatment that is safe for daily use.
How does the treatment feel?
The treatments provide a lovely, warm, and soothing sensation on the skin. They are completely pain-free and an easy way to give yourself a little luxury and professional skincare at home.
Many of our customers say that they not only use light therapy for the results but also because it's a truly relaxing moment – a small break in everyday life where they can unwind and enjoy some self-indulgence.
Is there scientific proof that light therapy has an effect on hair growth?
There are several scientific studies that show that light therapy can contribute to increased hair growth and reduced hair loss. Here are some of the most recognised:
Avci, P. et al. Role of Low-Level Light Therapy (LLLT) in Androgenetic Alopecia: A Review. Lasers Surg Med 46, 144-151 (2014).
Jimenez, J. J. et al. Low-Level Laser (Light) Therapy (LLLT) for Treatment of Hair Loss. Am J Clin Dermatol 15, 195-210 (2014).

Red Light Cap
How does the Red Light Cap work?
It looks like a regular baseball cap – but advanced technology is hidden under the brim. Our CE-certified red light cap uses 110 diodes with red (660 nm) and infrared (850 nm) light in low-level laser therapy (LLLT) to stimulate blood circulation in the scalp. The result is better oxygen and nutrient absorption, a healthier scalp, and hair that grows stronger and thicker over time. The light energises the hair follicles, reduces hair loss, reactivates growth at the root, and can also alleviate discomfort such as itching, irritation, and redness. It is comfortable to use, and you only need 10-30 minutes a day to achieve results – easy, safe, and completely without side effects.
Is there scientific evidence that light therapy has an effect on hair growth?
There are several scientific studies that show that light therapy can contribute to increased hair growth and reduced hair loss. Here are some of the most recognised:
Avci, P. et al. Role of Low-Level Light Therapy (LLLT) in Androgenetic Alopecia: A Review. Lasers Surg Med 46, 144-151 (2014).

Is it too late for me to start red light therapy treatment for hair growth?
Research shows that red light therapy works as long as the hair follicles are still alive. In people who are gradually losing hair (e.g., thinning hair, receding hairline), red light can activate passive hair follicles and contribute to new hair growth – even in areas that are starting to bald.
However, if you have been completely bald for many years (often 5+), the hair follicles usually enter a dormant phase. In this case, red light therapy will most often have little to no effect. However, it is impossible to know exactly when hair follicles die, so some may still experience an effect even after a long time.
To make it safe to try, we offer a 7-month money-back guarantee, so you can test whether red light therapy works for you without risk.
How quickly can I expect results?
1-2 months
Hair loss may temporarily increase at the start, as weak hair makes way for stronger new growth
3-4 months
You may start to see some hair growth and a reduction in hair loss
5-6 months
Further reduced shedding and visible new growth results
6+ months
Continued use will yield even better, more visible results and very minimal shedding!
We recommend using the cap for 10-30 minutes a day. It has a built-in timer function that makes it beep and turn off when the specified time has elapsed. The more often you use the cap, the better the effect.
Does it help with all types of hair loss?
Yes, red light therapy strengthens hair roots and provides a deep and lasting improvement to the entire hair structure.
Therefore, it helps with almost all hair problems, whether it's hair loss, thinning hair, bald patches, or something else.
How often should I use the cap?
We recommend daily use of 10-30 minutes. The time can also be spread out over the day.
