The laser hair growth cap typically consists of a cap, helmet, or hat embedded with numerous tiny laser diodes or light-emitting diodes (LEDs) that emit low-level laser light in specific wavelengths. When the cap is worn on the scalp, these lasers or LEDs emit light energy that penetrates the scalp tissues without generating heat. This light energy is thought to stimulate cellular activity, increase blood circulation to hair follicles, and promote the production of adenosine triphosphate (ATP), which is essential for cellular function and hair growth. As a result, hair loss has a negative psychological impact in addition to having an aesthetic impact, frequently leading to a decline in quality of life.
Through its photobiomodulatory action, low-level light therapy (LLLT) is a reliable non-thermal treatment for various dermatologic conditions. In addition, due to their affordability and simplicity, home laser and light therapy equipment for dermatologic diseases such as hair loss and aging skin are growing in popularity. Low-power lasers are reportedly used to treat pain or stimulate and improve cellular function, unlike the powerful lasers used in laser surgery to cut or burn tissue. Recent studies have shown effectiveness in controlling myopia, and the benefits seem to be restricted to a certain range of wavelengths. The Food and Drug Administration (FDA) of the USA has approved a number of these devices.
What is a Laser Cap?
A laser hair growth cap, also known as a laser hair growth or a laser therapy cap, is a wearable device to treat baldness while encouraging hair growth. It utilizes low-level laser therapy (LLLT), also called cold laser therapy or photobiomodulation, to stimulate hair follicles and encourage hair regrowth in individuals experiencing various degrees of hair thinning or loss. The idea behind laser caps is that by providing the necessary energy and stimulation to hair follicles, they can transition from a resting phase (telogen) to a growth phase (anagen), leading to thicker and fuller hair over time. Laser caps are designed for convenient home use and are typically used for several minutes a few times a week. They are considered a non-invasive and safe option compared to surgical hair restoration procedures, but it’s essential to consult a dermatologist before starting any hair loss treatment. The degree of success may also depend on factors such as the reason for hair loss, the level of hair thinning, and individual response to the therapy.
How Does Laser Therapy Regrow Hair?
Here are a few ways laser therapy could promote hair growth:
- Increased Blood Circulation: The low-level laser light emitted by laser therapy devices is believed to stimulate blood circulation in the scalp. Increased blood flow can promote healthy hair growth by providing the hair follicles more oxygen and nutrients.
- Stimulation of Hair Follicles: The laser light is absorbed by molecules within the cells of hair follicles. This absorption can increase the production of adenosine triphosphate (ATP), which provides energy to cells. This boost in energy may help stimulate the follicles to transition from a resting phase (telogen) to a growth phase (anagen).
- Reduced Inflammation: Some research suggests that LLLT may have anti-inflammatory effects. Chronic inflammation in the scalp can contribute to hair loss, and by reducing inflammation, laser therapy may create a more conducive environment for hair growth.
- Activation of Anagen Phase: Hair follicles have different growth phases, including anagen (growth), catagen (transitional), and telogen (resting). Laser therapy is believed to extend the duration of the anagen phase, leading to increased hair growth.
- Stimulation of Cellular Metabolism: Laser light may influence the metabolism of cells in the hair follicles, enhancing their overall function and promoting hair growth.
Reduction of Dihydrotestosterone (DHT) Effects: Occasionally, hair loss occurs, especially in cases of androgenetic alopecia (male- and female-pattern thinning or baldness), the hormone dihydrotestosterone (DHT) plays a role in miniaturizing hair follicles. Some studies suggest that LLLT may help counteract the adverse effects of DHT on hair follicles.
Are LLLT Devices Safe for Hair Growth?
LLLT (Low-Level Laser Therapy) devices are generally considered safe for hair growth when used as directed and within appropriate guidelines. These devices emit low-level laser or LED light not associated with generating heat, so there’s minimal risk of burns or discomfort. LLLT devices are known to have minimal side effects. Some individuals might experience mild scalp tingling or temporary redness, which usually subsides quickly after treatment. Several LLLT devices for hair growth have received clearance from regulatory agencies like the Food and Drug Administration of the USA (FDA) for safety and effectiveness. This can provide additional assurance of their safety. Some LLLT devices are not recommended for individuals with certain medical conditions, like skin cancers or photosensitivity disorders. You must read the product information and consult a dermatologist if you have concerns about using the device.
Benefits of Laser Hair Growth Cap
A laser hair growth cap offers several potential benefits for individuals seeking to address hair thinning or hair loss:
