The current role of laser/light sources in the treatment of male and female pattern hair loss.
J Cosmet Laser Ther. 2007 Mar;9(1):27-8. Review.
Over the past several years there has been great interest in the potential role of laser/light-based treatments for male and female pattern hair loss. Despite aggressive marketing and centers claiming great success in the treatment of hair loss there is little scientific data supporting laser/light sources in hair loss. This paper is a consensus of hair loss experts on the current scientific data, mechanisms of action, safety, protocols and recommendations regarding laser/light treatment for hair loss. The authors believe that, while seemingly safe, there are no controlled, peer-reviewed studies validating current devices for hair loss and that all patients should be medically evaluated for any hair loss by a physician specialist to rule out other underlying medical conditions or the etiology of hair loss.
I korthet, det finns inga vetenskapliga bevis for att det funkar.
Fast lita inte pa mig, vi saljer inte lasrar.

Phototherapy of androgenetic alopecia with low level narrow band 655-nm red light and 780-nm infrared light
Sang Seok Kim, MD, Kangdong Sacred Heart Hospital, Seoul, South Korea; Min Woo Park, MD, Kangdong Sacred Heart Hospital, Seoul, South Korea; Chong Ju Lee, MD, PhD, Kangdong Sacred Heart Hospital, Seoul, South Korea. Available online 20 January 2007.
Background: The therapeutic application of low energy laser has been used for photobiostimulation and low level laser therapy causes an increase of microcirculation of tissue and a reduction in inflammation. However, the effect of low level laser therapy on the stimulation of hair growth has not been investigated.
Object: To examine the effects of 655-nm red light and 780-nm infrared light on patients with androgenetic alopecia (AGA).
Methods: Patients treated their scalp by themselves, using a portable light source (655 nm and 780 nm), and irradiation was performed for 10 minutes once a day. Hairs in precisely defined circle at vertex (AGA region) and occipital sites of the scalp in 24 AGA male patients were evaluated using global photography and phototrichogram. Each circumscribed area of the scalp, centered with a dot tattoo to ensure reproducibility, was photographed just after shaving and two days later, the same area was again photographed. From the photo-images the hair density and anagen/telogen ratio (A/T ratio) were determined by image analyzer program. Each patient was evaluated at 0, 4, 9, and 14 weeks of phototherapy. After 14 weeks, the degree of satisfaction of patients and physicians were assessed.
Result: The results can be summerized as follows: (1) The mean hair counts of baseline were 137.3/cm2 on the vertex and 153.3/cm2 on the occiput, with the hair density of the occiput being significantly higher than that of the vertex. (2) The mean hair counts after 14 weeks, at the end of treatment, were 145.1/cm2 on the vertex and 163.3/cm2 on the occiput. Therapy with 655-nm red light and 780-nm infrared light significantly increased the density of hairs on both the vertex and occiput (P < .005). (3) The ratio of anagen/telogen (A/T ratio) of baseline was 79.7 on the vertex, 89.6 on the occiput and A/T ratio at the end of treatment were 84.7 on the vertex and 91.9 on the occiput, respectively. (4) The number of satisfied patients at the end of treatment was 20 (83.3%). No side effects were reported. Conclusion: The hair counts was affected beneficially in the vertex and occipital regions of the patients with androgenetic alopecia after 14-weeks of phototherapy with 655-nm red light and 780-nm infrared light.

Journal of the American Academy of Dermatology Volume 56, Issue 2, Supplement 2, February 2007, Page AB112 Poster Abstracts, 65th Annual Meeting Har även sett en studie/försök från den gamla Helium-Neon lasern (632,8 nm & 10 mw) som idag anses vara i princip värdelös, där fick 55,3 % respons av endast laser behandling. Det är/var för dåligt och nutida laserhuvar har en mycket bättre effekt och högre nanometer. Lägg sedan till Finasterid + Minox så att DHT nivåerna sänks, så får du en superboost och även lasern gör bättre nytta !! Det är väl självklart att laser gör bättre nytta om “roten” till det onda (DHT) minskas ? Jag tror att det ibland kan uppstå ett moment 22 annars för en del, lasern ökar blodcirkulationen och då är risken att det tillförs mera DHT till hårsäcken invärtes. Beroende på hur mycket hår personen har tappat och under hur lång tid…så krävs mera kompletteringar. För någon som börjar tappa hår så är laser+ minxo ofta tillräckligt, har det gått längre så rekommenderas även finasterid eller åtminstone saw palmetto. Tex har vi många kunder som kört med minox under flera år innan de kom hit, efter 4-5 mån med laser så börjar de få respons…det behöver inte innebära att lasern ensam ligger bakom återväxten..utan det är förmodligen kombinationen…helt plötsligt uppstår en synergi effekt och både laser & minox blir effektivare !! Jag skulle aldrig rekommendera en AGA kund endast laser, är både onödigt och dumt. Åtminstone minox bör man komplettera med. Det finns många studier på minox på nätet, senaste jag läste redovisade att ungefär 17% fick återväxt av endast minoxidil bruk, däremot bromsas håravfall för de flesta. Om inte det talar för lasers roll i det hela så.. ..
