Description
Technical Field
The invention relates to a method for treating alopecia by using low-energy laser and a hair care comb.
Background
Low energy laser therapy of alopecia is a non-invasive treatment aimed at stimulating the blood circulation and hair growth of the scalp. Such treatment modalities typically employ low power laser devices, such as low energy laser helmets or combs.
Low energy laser helmet: this is a head-mounted device incorporating a low energy laser transmitter. By directly irradiating laser light onto the scalp, the blood circulation of the scalp and the liveness of hair follicles can be promoted.
Low energy laser comb: this device is similar to a conventional comb, but has low energy laser emitters built into the teeth of the comb. While combing the hair, laser light may be irradiated to the scalp to stimulate hair growth.
Low energy laser hair growing helmet: this is a germinal helmet that covers the entire head, with low energy laser emitters. When the mask is used, the laser can uniformly irradiate all parts of the scalp, thereby promoting hair growth.
Semiconductor laser therapy (Low Level Laser Therapy, LLLT) is widely used as a miraculous revolutionary treatment for various painful and non-painful conditions such as dermatological lesions, arthrosis, neuropathy, muscle, tendon, myofascitis, vascular lesions, and other related conditions. The infrared laser with single wavelength is emitted to act on nerve roots, nerve stems and ganglia or pain spots and acupoints (clinical research shows that the laser with the wavelength of 810nm is most suitable for penetrating into human bodies) to generate a series of biological stimulation effects, regulate the pathophysiological states of the immune system, the nervous system, the blood circulation system and the tissue metabolism system of the human bodies, and play roles in easing pain, diminishing inflammation, promoting wound healing, promoting callus growth, nerve repair, improving organism immunity, improving blood circulation, promoting metabolism and the like, so that the purposes of curing diseases and recovering are achieved.
Four major therapeutic actions of semiconductor lasers:
diminishing inflammation and detumescence: the semiconductor laser irradiation can improve phagocytic capacity of leucocytes, activate cytochrome oxidase, enhance phagocytic capacity of body fluid, increase local immunoglobulin, enhance adrenal cortex system function, regulate immunity, diminish inflammation and inhibit bacteria, improve blood circulation, and relieve local congestion and edema.
Pain relieving and pain easing: the semiconductor laser irradiation can reduce peripheral nerve excitability and improve pain threshold; promoting the release of analgesic substances such as enkephalin, and reducing the content of 5-hydroxytryptamine in local tissues; accelerating blood circulation and reducing the accumulation of pain-causing substances.
Tissue repair: the semiconductor laser irradiation can promote wound healing, increase capillary blood vessel density of granulation tissue, improve microcirculation of the granulation tissue of the wound, promote ATP synthesis and stimulate protein synthesis; promoting proliferation of cell fibroblast, enhancing cell differentiation, regenerating new epithelium, and promoting repair of damaged tissue and bone tissue.
Physiological regulation: the semiconductor laser irradiation can enhance the immunity of the organism, strengthen the metabolism of cells and the organism, improve the circulation, regulate endocrine and make the blood and the cells bidirectionally regulate.
Drug and dose:
like other forms of drugs, LLLT has its active ingredient or "drug" (irradiation parameters) and "dose" (irradiation time).
Energy (J) or energy density (J/cm 2) is often used as an important feature of low power laser doses, but this ignores the fact that energy has two components, power and time: energy (J) =power (W) ×time (seconds) there is not necessarily a correlation between them, in other words, if the power is doubled, the time halved, the energy is the same but a different biological response is often observed.
LLLT is therefore best described in terms of two separate sets of parameters:
(a) Medicine (irradiation parameters)
(b) Dose (time)
In addition, there is evidence that different wavelengths, pulses, coherence, polarization, etc. have some impact on the magnitude of the bioregulation effect.
Therefore, the method for treating the alopecia is important by adjusting the power density of the low-energy laser lamp to a proper range, so that the laser lamp generates low-energy laser to irradiate the scalp layer and stimulate the cell proliferation of the scalp layer.

Relevant test records and literature records:
the literature of clinical efficacy studies of low energy laser treatment of androgenic alopecia mentions that Chin J Dermatol, july 2016, vol.49, no. 7, vol.2016, vol.49, vol.7, vol.2016:
the low-energy laser generally refers to a laser with a wavelength range of 500-1 nm and an energy of 1-4J/cm 2. It is reported that low energy lasers, particularly in the wavelength range of 650-900nm, with powers as low as 5mW, promote hair growth.
She Yaqi, yang Kai, liniment, etc. the mechanism of action of low energy laser in treating androgenetic alopecia [ J ]. Chinese cosmesis, 2019,28 (8): 151-154. Literature mentions:
low energy lasers have a majority of treatment wavelengths in the range 500 to 1 100nm, power densities in the range 3 to 90mW/cm2 and energies in the range 1 to 10J/cm2. LLLT is generally considered to be effective in treating androgenic alopecia using a light source with a wavelength range of 650-900nm and a power density of 5 mW.
The effectiveness and safety of low intensity laser devices for treating male and female hair loss one multicenter, randomized, sham device control, double-blind study literature mentions: LLLT having a wavelength of 500-1, 100 nanometers, a power density of 1-4J/cm 2 and a power density of 3-90 mW/cm2 are commonly used, and have proven beneficial in a variety of conditions, including wound healing, joint pain relief, mucositis prevention and treatment, and skin conditions LLLT having a wavelength of 650-900nm and a power of 5mW is considered an effective therapeutic option for male and female alopecia patients, based on anecdotal experience, despite the lack of comprehensive research to evaluate laser modalities.
