Det har genomförts försök & studier av olika läkare och forskare
runt om i världen. Inga av studierna har påvisat några biverkningar
(vilket är ganska så logiskt då samam våglängd som skapar liv används).
Alla studierna har varit positiva med olika grad (procent)redovisad återväxt !!
Det som saknas, i många personers ögon, är däremot långtgående studier. Hur länge ger behandlingen effekt egentligen ? Måste man stödbehandla direkt efter avslutat grund program ? Många såna frågor skulle man vilja ha svar på !! Nu får man istället utgå ifrån de befintliga klinikerna utomlands som har funnits längre än här i Sverige.
De har samlat på sig erfarenheter gällande preparat, utrustning (styrka & nanometer) och stödbehandlingar. Ingen av de här klinikerna vill bekosta långa, stora oberoende studier. Det finns en viktig anledning till det. Om LLLT (Low Level Laser Therapy) blir godkänd som medicinsk behandlingsform mot håravfall, ja då får ingen utan korrekt utbildning (läkare) utföra behandlingarna längre !! Laser mot håravfall omsätter enormt summor världen över och har varit stort i många länder redan från 2001 och framåt. Här nedan infogas en studie som t.om USA´s dermatologer ansåg så pass bra att de valde att publicera den i deras eget uppslagsverk !! Detta är enormt stort med tanke på att dermatologer rent allmänt har varit laser mot håravfalls största motståndare !!
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.

Excimer laser therapy of alopecia areata–side-by-side evaluation of a representative area]
[Article in German]

We report for the first time on hair regrowth in alopecia areata of the scalp achieved with the 308-nm xenon-chloride excimer laser in a prospective side-by-side trial. The alopecia areata had shown progression over a period of three years, and various treatments had not been effective. Out of a number of affected areas, one representative lesion was chosen; one half of it was treated, the other half remained untreated. After 27 sessions (200 – 4000 mJ/cm2, cumulative dose 52.6 J/cm2) over 3 months, only the treated area showed hair growth; which suggests that this was most probably not a spontaneous remission.

BACKGROUND: Alopecia areata is a rapid and complete loss of hair in one or several patches, usually on the scalp, affecting both males and females equally. It is thought to be an autoimmune disease which is treated with different modalities with variable success. Laser treatment of different wavelengths has been used in the management of this problem. OBJECTIVE: To study the effect of the pulsed infrared diode laser (904 nm) in the treatment of alopecia areata.Methods. Sixteen patients with 34 resistant patches that had not responded to different treatment modalities for alopecia areata were enrolled in this study. In patients with multiple patches, one patch was left as a control for comparison. Patients were treated on a four-session basis, once a week, with a pulsed diode laser (904 nm) at a pulse rate of 40/s. A photograph was taken of each patient before and after treatment. RESULTS: The treated patients were 11 males (68.75%) and five females (31.25%). Their ages ranged between 4 and 50 years with a mean of 26.6+/-SD of +/-13.8, and the durations of their disease were between 12 months and 6 years with a mean of 13.43+/-SD of +/-18.34. Regrowth of hair was observed in 32 patches (94%), while only two patches (6%) failed to show any response. No regrowth of hair was observed in the control patches. The regrowth of hair appeared as terminal hair with its original color in 29 patches (90.6%), while three patches (9.4%) appeared as a white villous hair. In patients who showed response, the response was detected as early as 1 week after the first session in 24 patches (75%), while eight patients (25%) started to show response from the second session. CONCLUSION: The pulsed infrared diode laser is an effective mode of therapy with a high success rate for resistant patches of alopecia areata.
