Red light hair
Sit back under the light.
Low-level red light for the scalp, a comfortable seat, and nothing to do while it runs.
What it is
Red light hair therapy uses low-level red light, aimed at the scalp. There is no UV and next to no heat. You sit back with the device over your head, and that is all there is to do.
Like red light on the skin, it is a slow habit rather than a one-off. The people who use it come regularly, over months.
People come for
- A regular scalp routine
- Adding to the hair care you already do
- A quiet sit with a book
What a session is like
- Length
- 30 minutes
- Wear
- Your normal clothes. Clean, dry hair.
The science
What the research says
Most of the research on red light for hair is on pattern hair loss, the gradual thinning that tends to run in families, with devices used several times a week for months. It is a small field, and most of its studies are short.
The larger trials
In four randomized trials, men and women with pattern hair loss used either a low-level laser comb or an identical-looking sham device on the scalp three times a week for 26 weeks. Hair counts in a marked area rose more with the real device than with the sham, and no serious side effects were reported. The device was a hand-held laser comb and the trials lasted six months, so they cannot say what happens with other devices, with longer use, or when hair thins for other reasons.

What a review of the field found
A systematic review of eleven studies found that most reported more hair, or thicker hair, after low-level light treatment, and that people's own satisfaction was positive but less striking than the measurements. The authors themselves urged caution in reading the results: the studies were few, and they varied in device, dose, and design.

Questions
Does it feel hot?
No. At most, faintly warm.
Will it regrow my hair?
Many people come to us for fuller, thicker-looking hair. Studies of people with pattern hair loss have found more hair after months of regular use, and results vary from person to person. Consistency matters, which is why we recommend four sessions a week.
How often should I come?
We recommend four sessions a week.
